Texas Prenuptial Agreement
Texas prenuptial agreements are governed by the Texas Uniform Premarital Agreement Act (Texas Family Code § 4.001 et seq.). Courts apply single review only — unconscionability is assessed at signing, not additionally at divorce. Only two defenses are permitted: involuntary execution or unconscionability; common law defenses are explicitly prohibited. Texas has no alimony floor — complete spousal support waivers are fully enforceable with no public assistance minimum, regardless of marriage length or future circumstances.
Bottom line: Texas earns an A+ grade. Single review, only two permitted defenses, banned common law challenges, and no alimony floor make Texas the strongest enforcement state in the country alongside New Jersey.

Texas Prenup Laws: Key Statutes Explained
Texas Uniform Premarital Agreement Act
Separate Property
All assets can remain separate property, avoiding costly divorce settlements. Joint assets and debts titled in both names are split 50/50 as marital property.
Unconscionability at Execution Only
Courts review unconscionability only at signing, not at enforcement. Changed circumstances during marriage will not invalidate a valid prenup.
Unconscionability Standard
A prenup is invalid only if extremely one-sided AND signed without fair financial disclosure (or written waiver) AND the challenging party lacked knowledge of the other's finances. Financial imbalance alone is not enough—even highly one-sided agreements are upheld.
Spousal Support Minimum
Complete waivers of spousal support are enforceable regardless of marriage duration or future circumstances. There is no public assistance minimum.
Timing
Courts have upheld prenups signed one day before the wedding when it was discussed for months prior. However, signing 30-60 days before with 1-2 weeks review time reduces challenge risk.
Independent Counsel
Not required if waived in writing. Lack of separate representation does not invalidate an agreement. However, independent counsel dramatically strengthens enforceability if challenged.
Financial Disclosure
"Fair and reasonable disclosure" of property and financial obligations required, or can be waived in writing.
Extremely High Burden to Challenge
Only two defenses allowed: involuntary execution or unconscionability. Common law defenses are prohibited. Challenging party bears the burden of proof.
Child Support
Child support and custody clauses are unenforceable and could undermine the entire agreement. Do not include.
Texas Prenuptial Agreement Court Cases
Marsh v. Marsh, 949 S.W.2d 734 (Tex. App.—Houston [14th Dist.] 1997)
Held that lack of attorney representation alone doesn't make agreement unconscionable; disparity and one-sidedness don't automatically equal unconscionability. Party has duty to read document before signing and is supposed to know contract contents.
Chiles v. Chiles, 779 S.W.2d 127 (Tex. App.—Houston [14th Dist.] 1989)
One-sided nature of prenup doesn't equal unconscionability; even disproportionate agreements aren't necessarily unconscionable.
Moore v. Moore, 383 S.W.3d 190 (Tex. App.—Dallas 2012)
Agreement set aside as involuntary due to fraud and duress where husband misrepresented changes, prevented wife's attorney from reviewing until hours before wedding, and directed her to hire attorney of his choosing.
Williams v. Williams, 720 S.W.2d 246 (Tex. App.—Houston [14th Dist.] 1986, no writ)
Signing prenup one day before wedding doesn't render it unconscionable where couple discussed terms for six months prior and wife had business experience.
Sheshunoff v. Sheshunoff, 172 S.W.3d 686 (Tex. App.—Austin 2005)
Marital property agreement case applying § 4.105, which mirrors § 4.006; court held that challenging party failed to timely raise defenses and that § 4.105(c) independently bars common-law defenses.
In re Marriage of I.C., No. 16-0770, 551 S.W.3d 119 (Tex. 2018)
Texas Supreme Court case enforcing "no-contest" clause in prenup; wife lost $5 million payment by attempting to rescind agreement, triggering forfeiture clause.
Osorno v. Osorno, 76 S.W.3d 509 (Tex. App.—Houston [14th Dist.] 2002)
Threat not to marry without signed prenup is insufficient to constitute duress; party has legal right not to marry.
Fazakerly v. Fazakerly, 996 S.W.2d 260 (Tex. App.—Eastland 1999)
Held that "the mere fact that a party made a hard bargain does not allow him relief from a freely and voluntarily assumed contract".
5-Step Checklist: How to Sign & Execute a Prenup in Texas
Step 1: Download and read the Texas prenuptial agreement
Start with our free template. It is written for Texas-specific statutes and case law under the Texas Uniform Premarital Agreement Act (Texas Family Code §§ 4.001–4.010). Read it in full — know what you are getting into legally with marriage. The 15+ pages is written thoroughly to include rebuttals to common legal challenges and fallback provisions. Texas is a community property state — without a prenup, virtually everything acquired during the marriage is split 50/50 regardless of who earned it or how it was titled.
Step 2: Draft changes on your own
See a clause you don't like? Copy it into an AI like Claude, explain what you'd like to change or what you want the clause "to do." Save any changes as a separate alternate version — don't overwrite the original. Bring both versions to your attorney review. Note: AI is often gender-biased and crafts terms beyond what is legally required. Push back on its output.
Step 3: Find a lawyer in your state
Find a matrimonial or divorce attorney in your state. Avvo, Findlaw, and Justia are good. Look for someone with 10+ years experience. Call or email and ask them how much to review your draft prenup and help with signing. Send them your draft.
Step 4: Meet your lawyer 4–6 months before the wedding
Our recommendation: sign the prenup before proposing. That way, you both get the legal work out of the way, and you know this is the right person to marry. Already proposed? 4–6 months before the wedding should leave you enough time to give your spouse 1–2 weeks to review the final draft and have it signed 60+ days before the wedding. Texas has no statutory minimum — Williams enforced a prenup signed one day before the wedding after six months of discussion. That said, preventing the other party from consulting counsel until hours before the wedding is precisely the conduct that voided the agreement in Moore. Adequate time and genuine access to independent counsel eliminate this risk entirely.
Step 5: Sign with your attorneys and notarize, then store
Execute the agreement with both attorneys present. This is the best approach to reduce challenge risk. Texas Family Code § 4.002 requires only a writing signed by both parties — no witnesses or notarization are mandated by statute. That said, notarization is standard practice and necessary if the prenup affects real estate. So use an attorney or notaries, but we highly recommend attorneys.
Texas Prenuptial Agreement: Frequently Asked Questions (2026)
1. What is a prenuptial agreement?
A prenuptial agreement is a legal contract signed before marriage that determines how assets, debts, and finances are handled during the marriage and if it ends. In Texas — a community property state — virtually everything acquired during the marriage is owned equally by both spouses and split 50/50 at divorce, regardless of who earned it. A prenup lets couples override that default: keep assets and debts separate, set their own terms for spousal support, build in privacy protections, and move any future dispute out of the courtroom and into mediation or arbitration. It is not a prediction of divorce — it is the legal architecture of the financial partnership.
2. Are prenups enforceable in Texas?
Yes — Texas is one of the strongest prenup enforcement states in the country. Under § 4.006 of the Texas Family Code, courts review unconscionability only at signing, not again at divorce. Only two defenses exist: involuntary execution or unconscionability coupled with inadequate financial disclosure. Section 4.006(c) goes further than most states by explicitly barring all common-law contract defenses — meaning fraud, duress, mistake, and undue influence cannot be asserted as independent grounds to void the agreement. The challenging party bears the full burden of proof. As Fazakerly v. Fazakerly put it: a hard bargain does not entitle a party to relief from a freely and voluntarily assumed contract.
3. What makes a prenup invalid in Texas?
Under § 4.006, only two grounds exist. First, involuntary execution — courts examine whether each party had access to independent counsel, whether assets were misrepresented, whether information was withheld, and whether duress or coercion occurred. Moore v. Moore voided a prenup on this ground because the husband prevented the wife's attorney from reviewing the agreement until hours before the wedding and directed her to hire counsel of his choosing. Second, unconscionability — but this requires all four elements simultaneously: the agreement was unconscionable at signing, the challenging party was not given fair financial disclosure, did not sign a written disclosure waiver, and lacked adequate knowledge of the other party's finances. One-sidedness alone is not enough. Leave child custody and child support out entirely — Texas courts will not enforce them and their inclusion can jeopardize the rest of the agreement.
4. How much does a prenup cost in Texas?
Attorney-drafted from scratch: $1,500–$5,000+ per side. A smarter approach: start with a free Texas-specific template, use an AI like Claude to draft changes, then hire an attorney only to review and assist with signing — typically around $500 per side. The key cost driver is complexity (number of assets, business interests, real estate, prior children). Either way, the cost is a fraction of litigating property division in a Texas divorce, where community property disputes routinely run $15,000–$50,000+ per side.
5. Can a prenup override community property in Texas?
Yes — this is the primary reason Texas couples get prenups. Under Texas Family Code § 3.002, all property acquired during marriage is presumed community property, owned equally by both spouses. A prenup under § 4.003 lets you reclassify what would otherwise be community property as separate property. That includes income earned during the marriage, investment gains, retirement contributions, and business appreciation. Without a prenup, a spouse's entire salary is community property from the first paycheck. With one, each spouse can keep what they earn. Joint assets and debts — anything both parties sign for together — can be designated 50/50 community property by agreement.
6. Can a prenup waive alimony in Texas?
Yes — and Texas enforces complete spousal support waivers more readily than almost any other state. Section 4.003(a)(4) explicitly permits the "modification or elimination of spousal support." Unlike many UPAA states, Texas did not adopt the provision (sometimes called UPAA § 6(b)) that allows courts to override a spousal support waiver if enforcement would make one party eligible for public assistance. There is no statutory alimony floor. A waiver will be upheld as long as the agreement itself passes the § 4.006 enforceability test — meaning it was signed voluntarily with adequate financial disclosure or a written disclosure waiver.
7. Can a prenup protect my business in Texas?
Yes, and for Texas business owners this is critical. Without a prenup, the business itself may remain separate property if it was founded before marriage, but all income it generates and any increase in its value during the marriage are community property by default — meaning your spouse has an equal ownership claim to the profits and growth. A prenup can reclassify business income, appreciation, and distributions as the founder's separate property. It can also prevent the other spouse from claiming a management role or forced buyout in divorce. For businesses with partners or investors, a prenup can satisfy operating agreement requirements that personal marital disputes will not affect the entity.
8. Do I need a lawyer for a prenup in Texas?
Not technically. Section 4.002 requires only a writing signed by both parties — no attorney, no witnesses, no notarization. But whether each party had access to independent counsel is the first factor courts examine when a prenup is challenged for involuntary execution. Marsh v. Marsh held that lack of representation alone does not make an agreement unconscionable, but Moore v. Moore voided a prenup where one spouse was effectively denied access to independent counsel. Both sides having separate attorneys is the strongest evidence of voluntary execution. Use a template to cut drafting costs — don't skip the attorney review.
9. How far in advance should I get a prenup in Texas?
Sign 60+ days before the wedding and give each party at least two weeks to review the final draft with their own attorney. Texas has no statutory minimum waiting period, and Williams v. Williams enforced a prenup signed one day before the wedding after six months of prior discussion. The risk is not timing per se — it is whether each party had meaningful access to independent counsel. Moore was voided not because of a short timeline but because the husband actively denied the wife that access. Best practice: sign before proposing. No time pressure, and you will both know this is the right person to marry.
10. Can you get a prenup after marriage in Texas?
No — by definition a prenuptial agreement must be signed before the wedding. But Texas offers a closely parallel option: a postnuptial or marital property agreement under Texas Family Code §§ 4.102–4.105. These agreements can partition community property into separate property, assign future earnings, and restructure ownership of assets acquired during the marriage. The enforceability framework under § 4.105 mirrors § 4.006 — the same two exclusive defenses (involuntary execution and unconscionability) apply, and common-law defenses are likewise barred. If you missed the prenup window, a postnuptial agreement achieves functionally the same result.
11. Does a Texas prenup need to be notarized?
No — Texas Family Code § 4.002 requires only a writing signed by both parties. No witnesses or notarization are mandated by statute. However, if the prenup affects real property — reclassifying a home, land, or investment property as separate property — notarization is necessary to record the agreement in county deed records and ensure it is enforceable against third parties. As a practical matter, notarization is standard practice and adds a layer of authentication that strengthens the agreement if challenged.
12. Can a prenup include child custody or infidelity clauses in Texas?
Child custody and child support: no. Texas courts determine custody based on the child's best interests at the time of divorce, and § 4.003(b) prohibits any provision that adversely affects a child's right to support. Including these terms can undermine the credibility of the entire agreement. Infidelity clauses: enforceable in limited form. Texas permits at-fault divorce considerations, and a prenup can include financial consequences triggered by proven adultery — such as a modified property split or forfeiture of spousal support. But courts will not enforce clauses that function as punitive penalties disproportionate to the marital estate. Draft narrowly and keep the amounts reasonable relative to total assets.
13. How can a prenup be challenged in Texas?
Only through the two statutory defenses in § 4.006. The challenging party must prove either (1) involuntary execution — which requires showing that a party was denied access to counsel, subjected to fraud, duress, coercion, or misrepresentation, or was prevented from understanding the agreement — or (2) that the agreement was unconscionable at signing and the party was not provided fair financial disclosure, did not sign a written waiver of disclosure, and lacked adequate knowledge of the other spouse's finances. All three disclosure sub-elements must be proven together; failing on even one defeats the defense. Section 4.006(c) bars all common-law contract defenses. Osorno v. Osorno held that a threat not to marry without a signed prenup is not duress — a party has a legal right not to marry.
14. Can a prenup protect inheritance in Texas?
Inheritance received during marriage is already separate property under Texas Family Code § 3.001(2) — but that protection erodes quickly without a prenup. If inherited funds are deposited into a joint account, used to improve jointly titled property, or commingled with community assets, the inheritance can lose its separate-property character and become subject to 50/50 division. A prenup can lock in the separate-property classification regardless of how the inheritance is used, held, or invested during the marriage. For blended families, a prenup can also ensure that inherited assets pass to children from a prior relationship rather than to a surviving spouse.
15. Can a "no contest" clause be included in a Texas prenup?
Yes — and Texas enforces them. In In re Marriage of I.C. (Tex. 2018), the Texas Supreme Court upheld a forfeiture clause that stripped a spouse of a $5 million payment she would have received under the prenup because she attempted to rescind the agreement and lost. The clause was triggered simply by challenging the prenup — not by winning or losing on the merits. If you include a no-contest clause, understand that it binds both parties equally: whoever challenges the prenup and fails forfeits what the agreement would have given them. This is one of the strongest deterrents to frivolous challenges available in any state and a significant reason Texas prenups are particularly durable.
