You signed a prenuptial agreement. You had it notarized. You moved on with your life, built a family, built assets — and then, years later, a judge threw it out.

This happens more often than most people expect. And it almost never happens because of something obvious — a typo, a missing signature, a forgotten page. It happens because the prenup was drafted without understanding how courts in that specific state evaluate these agreements, and without the factors that cause judges to uphold them rather than dismantle them.

The good news is that courts don't throw out prenups randomly. The same factors appear in case after case. Some prenups are almost impossible to challenge. Others are essentially waiting to fail. The difference between the two is knowable in advance — which means it's preventable.

Here are the six factors that determine whether a prenup holds up, ranked by impact.

The Six Factors That Determine Whether Your Prenup Holds Up

One important framing note before diving in: asset division is strong in nearly every state. A well-drafted prenup that keeps pre-marital assets in each party's name — bank accounts, real estate, business interests, investments — is enforceable with high confidence almost everywhere. The factors below apply primarily to alimony and spousal support provisions, where most prenup challenges actually occur and where state law diverges most dramatically.

If protecting pre-marital assets is your only goal, a prenup does that reliably across the country. If you also want to limit alimony exposure — which is where most of the legal complexity lives — these six factors are what you need to get right.

Factor 1 — Both Parties Have Independent Attorneys

This is the single most powerful enforceability factor in prenup law, and it's the one most couples underweight. Getting both parties represented by independent family law attorneys doesn't just check a box. It fundamentally changes how a judge evaluates the agreement — both at signing and years later at enforcement.

How a Judge Actually Thinks About Attorney Representation

Put yourself in the judge's position. A prenup comes before the court, challenged by one spouse. The judge — a generalist state court judge, not a matrimonial specialist — has to decide whether to enforce or invalidate an agreement signed years or decades earlier.

If both parties had independent matrimonial attorneys at the time of signing, the judge is looking at a document that two specialists in family law reviewed, advised on, and signed off on. These are attorneys who spend their entire careers drafting and litigating prenuptial agreements. They know the state statutes cold. They know the case law. The judge's instinct, unless something is plainly wrong or established precedent clearly requires a different outcome, is to defer. Why would a generalist judge second-guess two matrimonial attorneys who were specifically retained to protect each party's interests?

The answer, in most cases, is that the judge won't. Attorney representation on both sides is the closest thing to a prenup enforcement guarantee that exists.

What Happens When One Party Has No Attorney

Now flip the scenario. One party — typically the less-monied spouse — had no attorney when the prenup was signed. At enforcement, the judge can't defer to professional review that never happened. Instead, something else occurs: the judge effectively steps into the role of attorney for the unrepresented party.

Every provision gets examined more closely. Was there full financial disclosure? Is anything overreaching? Did the unrepresented party genuinely understand what they were signing and what they were giving up? The judge isn't neutral anymore — the judge becomes a de facto advocate for the person who had no legal representation, because no one else was there to protect them at the time.

This dramatically raises the chance of invalidation. Not because the prenup was necessarily unfair, but because there's no professional presumption of fairness to lean on. The judge has to make that determination independently, which means every vulnerability in the document gets surfaced and scrutinized.

Almost No State Requires It — But Almost Every Court Rewards It

Here's the frustrating part: the vast majority of states don't legally require independent counsel for a prenup to be valid. Only California mandates it as a precondition for enforcing spousal support provisions. In most other states, you can technically sign a prenup without an attorney and have it be legally valid.

But "technically valid" and "likely to survive a challenge" are different things. The absence of attorneys doesn't void a prenup — it invites scrutiny that the presence of attorneys forecloses. It's the single cheapest insurance policy available in the entire prenup process.

The practical implication for how to use PerfectPrenup: the document gets you to the attorney already 80% done — with a state-specific, case-law-calibrated, 15+ page prenup that reflects your state's controlling statutes. The attorney's job at that point is review and refinement, not drafting from scratch. Family law attorneys charge $200–$400 per hour. Bringing a near-finished document cuts that time dramatically — and both parties still get the attorney representation that makes the agreement nearly bulletproof.

Factor 2 — Your State's Review Standard

The second most important variable is one most couples never hear about: when does your state's court evaluate whether your prenup is fair?

This is the difference between single-review and dual-review states, and it determines whether a judge can second-guess your prenup years after you signed it — or whether signing with proper process locks it in permanently.

Single-Review States — Scrutiny at Signing Only

In single-review states, a court evaluates fairness at exactly one point in time: the moment the prenup was executed. The legal question is whether the agreement was unconscionable at execution — that is, whether it was fundamentally unjust on the day both parties signed it.

Courts ask: Was it voluntary? Did both parties have adequate financial information about each other? Was anyone coerced or deceived? Was the deal so one-sided at signing that it was unjust as written?

If the procedural checklist is satisfied — both parties had attorneys, adequate time to review, complete financial disclosure, no pressure — a single-review state court will generally enforce the prenup. It doesn't matter if the income gap widened dramatically over the course of the marriage. It doesn't matter if one spouse left the workforce to raise children. The deal was evaluated at signing. That's the entire inquiry.

This creates a highly predictable environment. Follow the process, and the prenup holds.

Dual-Review States — Courts Can Re-Examine at Divorce

Dual-review states apply a second layer of scrutiny on top of the signing-day review. Courts in these states also ask whether enforcing the prenup would be unconscionable at the time of divorce — sometimes decades after the agreement was signed.

This distinction sounds procedural. Its consequences are not.

In a dual-review state, a prenup that was completely reasonable the day you signed it can be unwound at divorce if circumstances changed enough. One spouse's income grew dramatically. The other left the workforce. What seemed like a fair limitation on alimony at engagement now looks, to a judge, like it would leave one party unable to support themselves.

There's also a strategic reality that's worth naming directly: when a spouse knows they can challenge the prenup at divorce, they have more incentive to file for divorce and more grounds to litigate. The agreement becomes a starting position in negotiation rather than a settled outcome. Dual-review states don't just create legal uncertainty — they create financial incentives that work against the stability of the marriage itself.

State Enforceability Grades — How the Biggest States Stack Up

The grades below reflect enforceability of alimony and spousal support provisions specifically. Asset division is strong in all of these states.

‍Texas and New Jersey (A+): Single-review, and uniquely, neither state imposes a statutory alimony floor. A prenup in either state can limit spousal support to near-zero and courts will generally uphold it — even if the result would leave a spouse eligible for public assistance. Texas courts have held explicitly that a hard bargain is not grounds for relief from a freely signed contract. New Jersey takes a similarly strong pro-enforcement position. For couples who want the most reliable alimony protection available, these are the benchmark jurisdictions.

Florida (A): Single-review with a public assistance floor. Courts will override an alimony waiver only if enforcement would leave a spouse dependent on government benefits — a low bar that doesn't meaningfully constrain most prenups. Florida courts interpret prenup language broadly in favor of enforcement and consistently uphold agreements challenged on fairness grounds when the procedural requirements were met.

Illinois (A-): Single-review with an "undue hardship" standard that sits slightly above public assistance. Illinois courts have defined undue hardship narrowly — In re Marriage of Amyette (2023) described it as a mathematically demonstrable likelihood of homelessness or sub-standard housing. In re Marriage of Barnes (2001) established that alimony waivers are valid under the Illinois Uniform Premarital Agreement Act when the agreement is voluntary, disclosure is fair and reasonable, and there's no unconscionability — and In re Marriage of Prill (2021) confirmed the standard cleanly: "unfair does not equal unconscionable." Illinois is an excellent prenup state with a marginally higher floor than Texas or Florida.

New York (C): Dual-review for spousal support. Property provisions are reviewed only at signing, but maintenance provisions are reviewed again at enforcement. Courts can strike alimony provisions that would be unconscionable given circumstances at divorce. A public charge floor applies — courts will invalidate waivers that would leave a spouse dependent on government assistance. New York prenups can and do hold up with careful drafting, but the dual-review standard creates meaningful uncertainty and litigation incentive. More on the 2025 disclosure trap in Factor 3.

California (C): The most aggressive dual-review state. No bright-line threshold for conscionability — it's evaluated at judicial discretion at enforcement. Two landmark cases define the current landscape, examined below.

The California Deep Dive — What Dual-Review Looks Like in Practice

California produces the most instructive case law on dual-review risk, and it's the state where document quality matters most. Three cases frame the current environment.

In re Marriage of Facter (2013) — Complete Waiver Struck Down

Facter was the first California appellate decision to apply dual-review unconscionability to spousal support, and it established the principle directly. An attorney husband earning approximately $1 million per year with over $10 million in assets divorced his wife of 16 years. She had been out of the workforce during the marriage and had no separate assets. The prenup contained a complete spousal support waiver.

The California Court of Appeal struck the waiver. The court cited the "dramatic disparity" in financial positions and "inequality of bargaining power," finding it unconscionable to leave the wife with nothing after 16 years given the income gap. Facter opened the door for California courts to evaluate the practical consequences of enforcement, not just the procedural fairness of signing.

In re Marriage of Zucker (2022) — The 10% Watermark

Zucker gave practitioners the most concrete data point yet on where the floor sits. The parties had a prenup capping the wife's spousal support at $6,000 per month. By the time of divorce, the husband was earning approximately $250,000 per month. The trial court found that $6,000 per month was "merely 10% of the probable statutory order" and struck the provision as unconscionable. The Court of Appeal agreed, finding the cap "oppressive" given the income gap.

Critically, the Zucker court reached this result even on a pre-2002 prenup, routing through a public policy argument under Family Code §1612(a)(7). The message from California courts has been consistent: extreme alimony limitations in marriages with large income disparity are vulnerable regardless of how procedurally sound the signing was.

Zucker establishes the current watermark: alimony at 10% of the probable statutory award was struck down as oppressive. California's statutory formula runs roughly 40% of the payor's income for long marriages. Ten percent of 40% means a cap at approximately 4% of the payor's income crossed the line. A well-drafted California prenup needs to land meaningfully above that.

In re Marriage of Miotke (2019) — What Actually Holds Up

Not every California alimony provision fails, and Miotke is the important counterexample. A mutual alimony waiver was enforced when both spouses had similar earning histories and the wife had $107,000 in net worth at signing despite not working at that point. The court found no unconscionability — neither party had dramatically more financial power than the other, and neither faced genuine hardship from the waiver.

Miotke tells us California courts will uphold prenups between financial equals. The risk concentrates in marriages with large income or asset disparity — which describes many of the couples most motivated to get a prenup in the first place.

How PerfectPrenup Calibrates for California

The PerfectPrenup California template is built around the Zucker/Facter/Miotke triad. Rather than a flat alimony waiver or fixed dollar cap — both of which carry serious risk — the formula starts alimony at 10–20% of the payor's income (approximately 25–50% of the statutory amount), scaling with family size and marriage length. This positions the agreement well above the Zucker watermark.

More importantly, the California template cites these cases directly in the document — building the conscionability record at the time of signing. When a court reviews the agreement, the parties demonstrably understood what Zucker said, knew what the statutory formula produced, and chose terms calibrated against that precedent. That's meaningfully different from a generic template that contains none of this.

No one can guarantee a California judge's ruling. The goal is to land well above the threshold that was struck down, with case law support in the document, so the court has a principled basis for upholding the agreement rather than a ready-made precedent for striking it. Even in California, a well-drafted prenup can likely reduce alimony by roughly 75% from the statutory default — and protect assets strongly — which is dramatically better than no prenup at all.

Factor 3 — Full Financial Disclosure

Incomplete financial disclosure is one of the most common grounds for prenup invalidation, and it's entirely preventable. Courts don't require perfection — they require good faith. But "good faith" has a specific meaning here, and it's more demanding than most couples expect.

Everything Over $1,000 — No Exceptions

The threshold for what to disclose is low: everything with a value over $1,000. That means bank accounts, investment accounts, retirement accounts, real estate, vehicles, business interests, cryptocurrency, valuable personal property, and debts. All of it, listed in a financial disclosure schedule attached to the prenup.

Courts don't forgive "I forgot about that account" or "I didn't think it was worth disclosing." An asset that isn't disclosed isn't covered by the prenup — which means it can be split 50/50 at divorce as if the prenup didn't exist for that asset. And if a court finds that the omission was deliberate, it doesn't just lose that asset: it can invalidate the entire prenup on fraud grounds.

Disclose everything. The downside of over-disclosure is zero. The downside of under-disclosure is catastrophic.

How to Value Your Assets — And Why to Round Up Reasonably

You don't need a formal appraisal for most assets. You need a good-faith, reasonable estimate — and the direction to err is up, not down.

For real estate: print out the current Zillow estimate or use the most recent tax assessment. For investment and retirement accounts: use the current brokerage statement balance. For business interests: use a recent revenue multiple, an accountant's estimate, or the most recent valuation if one exists. For vehicles: use the purchase price or a reasonable fair market estimate — a car you bought for $30,000 can be listed at $30,000 or a reasonably depreciated figure. You don't need to account for every modification or improvement. You also don't need to inflate it beyond reason. If you paid $30,000, you don't list it at $100,000 because you replaced the tires and added a sound system.

The goal isn't precision. It's demonstrated good faith. A court that sees thorough, generous disclosures is going to be far less sympathetic to a claim of hidden assets than one that sees a sparse list that conveniently omitted the most valuable things.

What Happens When You Hide Assets

Two outcomes, both bad. If a hidden asset is discovered at divorce, it typically gets split 50/50 as marital property — because it wasn't included in the prenup's separate property protections, it falls back into the default divorce rules. The prenup you signed to protect that asset ends up not protecting it at all, because you didn't disclose it.

The worse outcome: if a court finds that the non-disclosure was intentional — that you knew about the asset and left it off the list — it can invalidate the entire prenup on fraud grounds. You don't just lose the hidden asset. You lose the entire agreement. Every protection you negotiated, gone, because you tried to hide something.

Hiding assets doesn't protect them. It either loses them at divorce or loses the whole prenup.

New York's 2025 Rule — Income Must Be in the Document

If you're getting married in New York, there's a new disclosure requirement that has caught many couples off guard. Per J.M. v. G.V. (2025 NY Sup. Ct.), a maintenance waiver in New York must now include the parties' actual income figures and the calculated statutory maintenance amount being waived. Without that specific schedule in the document, the maintenance waiver is void — even if everything else about the prenup was properly executed.

Any New York prenup drafted before this ruling, or any template that doesn't account for it, has a meaningful vulnerability. PerfectPrenup's New York template includes this schedule as required.

Factor 4 — Document Quality

A prenup is only as strong as the document itself. A poorly drafted agreement — one that uses generic language, omits state-specific provisions, lacks fallback clauses, and doesn't cite controlling case law — gives a motivated challenger a roadmap to dismantle it. A well-drafted one closes those doors.

Generic Templates Don't Know What State You're In

Most online prenup templates are the same document regardless of where you live. They're written to be broadly applicable across all 50 states, which means they're optimized for none of them.

This matters enormously in practice. Alimony provisions that are entirely safe in Texas may be dangerously aggressive in California. Disclosure requirements that satisfy Florida courts may fail New York's 2025 income disclosure rule. The timing language that works in Illinois may not meet California's mandatory seven-day waiting period. A state-specific prenup isn't a marketing claim — it's the difference between an agreement that reflects controlling statutes and case law in your jurisdiction and one that was designed for no particular state at all.

No Case Law Citations Means No Conscionability Record

In dual-review states especially, the content of the document matters beyond just the legal provisions. Citing controlling case law inside the prenup itself — Zucker in California, J.M. v. G.V. in New York — demonstrates that both parties understood the legal landscape at the time of signing. It makes it significantly harder for a challenging party to claim they didn't understand what they were agreeing to or what they were giving up. It builds the evidentiary record for conscionability before anyone sets foot in a courtroom.

Generic templates contain none of this. They were written to apply everywhere, so they reference nothing specific to your state. In a dual-review challenge, that's an absence the challenging party will exploit.

Backup Clauses — What They Are and Why They Matter

Even a well-drafted prenup can have individual provisions challenged. What happens when a court strikes one of them is where most people don't think ahead.

Backup clauses — sometimes called reformed formula fallbacks — are alternative provisions that activate automatically if a primary clause is struck or modified by a court. Instead of leaving a judge to decide from scratch what an invalidated alimony cap should be replaced with, you've already negotiated a replacement — one that's more conservative but still far better than the full statutory default.

Without backup clauses, a struck alimony provision gets replaced by whatever the judge decides, which in practice means the full statutory award. The agreement that was supposed to limit your alimony exposure suddenly provides no protection at all on that point, because there was nothing in the document to fall back to. With backup clauses, a struck primary provision triggers a pre-negotiated fallback that still limits exposure — just less aggressively.

PerfectPrenup includes fallback language for alimony provisions specifically, because that's where challenges concentrate.

15+ Pages Is a Feature, Not a Problem

Most couples encountering a 15–20 page prenup for the first time wonder if it's unnecessarily complex. It isn't. A sophisticated prenup is long because it's doing real legal work that short documents can't accomplish.

State-specific statute references. Controlling case law citations. Backup alimony formulas. Financial disclosure schedules for both parties. Asset update and reaffirmation provisions. Transmutation prevention language. Severability clauses structured to protect surrounding provisions if one is struck. Language comprehension provisions that reduce challenge risk for non-native English speakers. Definitions that close loopholes.

A four-to-six page template cannot cover what needs to be covered. Length isn't padding. It's protection.

PerfectPrenup runs 15–20 pages by design — and it's free. Download the version for your state, read every section, use AI to draft any modifications you want, and bring the near-finished document to a family law attorney for final review. You'll walk in with something that reflects months of state-specific legal research. Your attorney's job is to refine and sign off, not to start from a blank page.

Factor 5 — Timing

When you sign a prenup matters almost as much as what it says. Courts read timing as a signal about voluntariness — and late-stage prenups face a presumption of duress that's hard to overcome regardless of how fairly the agreement was drafted.

The Timing Ladder

• A few days before the wedding — High invalidation risk. The duress presumption is strong. Even with attorneys present, a court is going to look hard at an agreement signed when a party had no realistic ability to walk away from a wedding already in motion. Texas is an outlier here — courts have upheld prenups signed one day before — but Texas is the exception, not the rule.
• Under 30 days before — Risky in most states. Courts will scrutinize timing and look closely at whether the less-monied party had genuine ability to review, ask questions, and negotiate.
• 60+ days before the wedding — The safe zone. Duress arguments become much harder to sustain when there was ample time to review, consult, and decide. This is the minimum recommendation.
• Before proposing — Ideal. More on this below.

The practical recommendation: reach out to a family law attorney 4–6 months before the wedding, present the final version of the prenup 2–3 weeks before signing, and sign at least 60 days before the ceremony.

Sign Before Proposing — Prenups Are on the Path to Marriage

The best prenup isn't a last-minute legal ambush. It's a conversation two people have before committing to each other.

Signing a prenup before proposing means both parties approached the marriage with clarity about financial roles, responsibilities, and expectations — before wedding planning started, before venues were booked, before the social and emotional weight of a public engagement made it psychologically harder to walk away. There's no duress argument when the prenup predates the proposal. There's no "sprung on me before the wedding" narrative when the wedding wasn't even on the table yet.

It also means the prenup conversation happens in the right context: not as a legal interruption to wedding planning, but as part of figuring out whether and how you both want to build a life together. What are your financial roles? What do you each bring? What happens if things don't work out? These are marriage conversations, not divorce conversations — and they belong on the path to the proposal, not between the proposal and the ceremony.

California's Hard Rule — 7 Days, No Changes After the Final Draft

California imposes a statutory bright-line rule that has voided otherwise valid prenups: there must be a minimum 7-day gap between presenting the final draft and signing. No substantive changes can be made during that period. This isn't a recommendation — it's a legal requirement under Family Code §1615(c)(2), and violating it can void the agreement regardless of everything else that was done correctly.

The practical implication: in California, the prenup drafting process needs to be completed and finalized well before the signing date. You can't make a change on day 6 and sign on day 7. The clock resets with each substantive revision.

This is one reason PerfectPrenup recommends the 60+ day timeline generally, and why California couples especially should start the process 4–6 months out.

Don't Surprise Your Spouse

A prenup presented as a surprise — particularly close to the wedding date — signals something courts don't like: that one party wanted leverage, not partnership. Even if the surprise prenup is otherwise well-drafted and procedurally compliant, the circumstances of how it was presented become part of the duress analysis.

Present the prenup early. Explain the reasoning. Go through it together. A spouse who understands why the prenup exists, has had time to read and ask questions, and feels like a participant in the process rather than a recipient of a legal demand is a much weaker challenge at enforcement.

Factor 6 — What Should Never Be in Your Prenup

A few provisions don't just fail on their own — they can give a court grounds to question the validity of the whole agreement. Keep these out entirely.

Child Support and Custody — Never

Child support and custody provisions are unenforceable in every state without exception. Child support is a right of the child, not a right of either parent to waive in a contract. A court will not enforce any provision that purports to limit, waive, or predetermine child support or custody arrangements.

More importantly, including these provisions can give a judge grounds to look more critically at the rest of the agreement. If you're trying to do things a prenup can't legally do, a court may wonder what else was overreaching. Leave child support and custody out entirely.

Anything Illegal or Against Public Policy

Provisions that require illegal conduct, attempt to penalize a spouse for filing for divorce, or violate state public policy will be struck — and depending on how the agreement's severability language is written, a struck provision can contaminate the surrounding clauses. Use proper severability language, and don't include anything that's clearly impermissible under your state's law.

A Note on Negotiation — What Heavy Back-and-Forth Actually Signals

Prenups shouldn't be highly negotiated documents in the way commercial contracts are. Small drafting tweaks, language clarifications, minor adjustments — that's normal and healthy. What isn't normal is a partner who treats the prenup as a term sheet for their preferred divorce outcome, demanding major changes to increase their potential payout in the event the marriage fails.

California's 7-day rule captures this intuition well: the final draft is presented, reviewed, and signed. It isn't a starting bid.

A prenup is an agreement about building a marriage — about roles, responsibilities, shared goals, and how you both intend to contribute to the relationship. It's not a negotiation about how to divide assets that don't yet exist, from a marriage that hasn't happened yet, in a divorce neither party should be planning for. If one party's primary interest in the prenup process is maximizing their divorce settlement, that's not a prenup problem. That's a compatibility problem, and it's better to know before the wedding than after.

Both parties should be able to read the prenup, understand every section, and agree that it reflects a fair and reasonable picture of what each person is bringing to the marriage and what each person is committing to. That's the standard. Not perfect equality on every line, but a document both parties can stand behind.

What a Prenup Is Actually For

Prenups carry a cultural reputation as cynical documents — exit plans dressed in legal language, proof that you're already planning for failure. This gets the purpose exactly backwards.

Removing the Financial Incentive to Destroy a Marriage

In many states, divorce without a prenup creates a substantial financial windfall for one party. State divorce law, applied by default to couples with no agreement, can transfer significant assets and create multi-year alimony obligations based purely on the duration of the marriage — regardless of who contributed what, how either party behaved, or what either person actually needs going forward.

That structure creates a financial incentive that corrodes marriages. If staying married means leaving significant money on the table compared to divorcing, that dynamic — even if never spoken aloud — puts pressure on the relationship. A prenup doesn't plan for divorce. It removes the payday dynamic, so both parties benefit from the marriage succeeding rather than from ending it.

Marriage is about two people contributing to a union — building something together over time. A prenup, designed well, reflects that reality. It aligns interests rather than creating competing ones.

A Prenup Is Worth Getting in Every State — Even California

Even in dual-review states with genuine uncertainty around alimony provisions, the math strongly favors getting a prenup. Asset protection is strong almost everywhere. Alimony can be substantially reduced from statutory defaults in every state. The open-ended judicial discretion that makes divorces so unpredictable and expensive — the blank check handed to a judge who knows nothing about your marriage — is constrained.

The goal of a prenup isn't a perfect outcome that locks in every negotiated term forever. It's a dramatically better outcome than the alternative. Don't let the complexity of dual-review states talk you out of an agreement that protects you substantially. A C-grade prenup state is still worth getting a prenup in. Don't let perfect be the enemy of dramatically better.

Before You Sign — Summary Checklist

Work through this before any prenup is executed:

Get independent attorneys for both parties. The single most important factor. Both parties need their own family law attorney — not the same attorney, and not an attorney with any connection to the other side. In California, independent counsel is legally required for alimony provisions. Everywhere else, it's the strongest signal a court can see that the agreement was voluntary and understood.

Know your state's review standard. Is your state single-review or dual-review? The answer changes how aggressively alimony provisions can be structured and how much litigation risk you're carrying. Check your state's page at PerfectPrenup for statutes, case law, and an enforceability grade.

Start 4–6 months before the wedding, sign 60+ days out. Late-stage prenups invite duress challenges. Build in enough time for both parties to review thoroughly, ask questions, consult with counsel, and sign without any wedding-day pressure in sight.

Consider signing before proposing. The ideal timeline. A prenup that predates the proposal has no duress narrative, no wedding pressure, and no "sprung on me at the last minute" argument available at enforcement.

Disclose all assets and income over $1,000 in writing. Attach financial disclosure schedules to the prenup. Round up on valuations. Use Zillow estimates, brokerage statements, and purchase prices. Hidden assets either get split 50/50 or void the whole agreement.

Use a state-specific document with controlling case law cited. Not a generic template. Your state's statutes and case law control enforcement. The document needs to reflect them — and in dual-review states, should cite them explicitly.

Confirm backup/fallback clauses are included for alimony provisions. If a primary clause is struck, a fallback should activate. Without it, a struck provision gets replaced by the full statutory default.

Never include child support or custody provisions. Unenforceable everywhere. Can undermine the validity of the surrounding agreement.
