Maryland Prenuptial Agreement
Maryland prenuptial agreements have no governing statute — enforceability is entirely judge-made law. However, Knizhnik (2024) held that courts apply single review only — unconscionability is assessed at signing, not additionally at divorce — and Martin v. Farber (1986) established that unconscionability alone cannot void an otherwise valid prenup. The key standard is whether the agreement was signed "freely and understandingly." Financial disclosure requirements and the alimony floor are not codified, leaving both judge-dependent.
Bottom line: Maryland earns a B grade. Single review and a high unconscionability bar are meaningful strengths, but the absence of a statute creates uncertainty on disclosure and support floor standards. A prenup is still far better than none.

Maryland Statute is Lacking
Maryland does not have specific laws that uphold the enforceability of prenuptial agreements. Instead, it relies on legal precedents.
Maryland Prenuptial Agreement Court Cases
Stewart v. Stewart, 214 Md. App. 458 (2013)
Prenuptial agreement signed four days before wedding was upheld where husband had $2 million in assets, wife had none, wife retained rights to alimony and monetary award, and court found no "overreaching" despite wife signing without attorney because she signed "freely and understandingly" and knew assets were substantial.
Knizhnik v. Knizhnik, Case No. 1732, Sept. Term 2022 (Md. App. Apr. 11, 2024)
Appellate Court of Maryland rejected the "second look" approach to prenuptial agreements, holding that unconscionability is reviewed only at time of execution, never at time of enforcement.
Martin v. Farber, 68 Md. App. 137 (1986)
Court held that an "otherwise valid" prenuptial agreement cannot be set aside on grounds of unconscionability alone, establishing leading Maryland authority that valid prenups cannot be invalidated solely for being unconscionable.
5-Step Checklist: How to Sign & Execute a Prenup in Maryland
Step 1: Download and read the Maryland prenuptial agreement
Start with our free template. It is written for Maryland-specific common law standards governing prenuptial agreements, including Cannon v. Cannon, 384 Md. 537 (2005), Stewart v. Stewart, 214 Md. App. 458 (2013), and Knizhnik v. Knizhnik (2024). 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.
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 2 weeks to review the final draft and have it signed 60+ days before the wedding. Maryland practitioners recommend a minimum of one week before the wedding — a 2021 case voided an agreement signed six days out, and courts look hard at whether the challenging party had adequate time to consult an attorney and understand what they were signing.
Step 5: Sign, notarize, and store the agreement
Execute the agreement with both attorneys present — their witness signatures carry more enforceability weight than a standalone notary. Maryland law requires only a writing signed by both parties — no witnesses or notarization are mandated. That said, notarization (without witnesses) is the standard practice; it authenticates signatures and provides evidence of voluntariness if the agreement is later challenged. Each party keeps a signed original, and so should each party's attorney. Store yours somewhere secure like a safety deposit box. Create a .pdf and save it via a backup drive and email.
Maryland Prenuptial Agreement: Frequently Asked Questions (2026)
1. Are prenuptial agreements enforceable in Maryland?
Yes. Maryland courts enforce prenups as contracts, but with heightened scrutiny because engaged couples are in a "confidential relationship" as a matter of law. The controlling standard comes from Cannon v. Cannon, 384 Md. 537 (2005): the party seeking to enforce the prenup bears the burden of proving there was no "overreaching" — meaning no unfairness in either the signing process or the terms. This is the reverse of most states, where the party attacking the prenup bears the burden. If the enforcing party can show full financial disclosure and voluntary execution, the agreement is very likely to hold. Maryland has no prenup statute, so all enforceability rules come from case law and general contract principles.
2. How much does a prenup cost in Maryland?
Attorney-drafted from scratch: $1,500–$5,000+ per side, depending on asset complexity. A more cost-effective approach: start with a Maryland-specific template, draft changes with AI assistance, then hire an attorney only to review, negotiate final terms, and supervise signing. That approach typically runs $500–$1,000 per side for the attorney portion. Additional costs may include financial advisor consultations ($200–$500/hour) if complex assets like businesses or trusts need valuation. Two attorneys (one per side) are not legally required but significantly reduce the risk of a later overreaching challenge.
3. What makes a prenup invalid in Maryland?
Maryland courts apply a two-prong "overreaching" test from Cannon v. Cannon (2005). Either prong failing can void the agreement. Prong 1 (procedural): Did the challenging party sign freely and understandingly? Courts look at whether there was adequate time to review, opportunity to consult independent counsel, and full financial disclosure. Prong 2 (substantive): Were the benefits received commensurate with what was given up? Terms so one-sided they "shock the conscience" fail this prong. Beyond overreaching, standard contract defenses also apply — fraud, duress, coercion, mistake, undue influence, or mental incompetence. Child custody or support provisions will not be enforced and can jeopardize the rest of the agreement.
4. Can a prenup waive alimony in Maryland?
Yes, but with risk. Maryland prenups can limit or waive alimony, and courts generally enforce these provisions under the Cannon overreaching framework. However, Maryland has no statute defining the outer boundary of alimony waivers, so enforcement depends on judicial discretion. A court may refuse to enforce a complete waiver if doing so would leave one spouse destitute or dependent on public assistance — particularly after a long marriage with significant economic disparity. The safer approach is to structure alimony as a formula tied to marriage duration and contributions rather than a flat waiver. This passes substantive-prong scrutiny more reliably while still giving both parties predictability.
5. Do I need a lawyer for a prenup in Maryland?
Not legally required, but strongly recommended. Maryland courts evaluate whether each party had the "opportunity" to consult independent counsel, and the absence of an attorney weighs toward a finding of procedural overreaching. In Stewart v. Stewart, 214 Md. App. 458 (2013), the court upheld a prenup signed without counsel — but only because the wife had adequate time to review, understood the husband's assets were substantial, and retained rights to alimony and a monetary award. Critically, Maryland places the enforcement burden on the party seeking to uphold the agreement. Having both sides represented by separate attorneys is the most reliable way to carry that burden.
6. Can a prenuptial agreement protect my business in Maryland?
Yes, and this is one of the strongest reasons to get a prenup in Maryland. Without one, if your business appreciates in value during the marriage — or if marital funds or your spouse's efforts contribute to its growth — a court may classify a portion of that increased value as marital property subject to a monetary award under FL Art. § 8-205. A prenup can designate the business, including future appreciation, revenue, and intellectual property, as separate property. For maximum enforceability, include a current business valuation in your financial disclosure, define how future growth will be treated, and specify a valuation method (or cap) for divorce purposes.
7. Does a Maryland prenup need to be notarized?
No. Maryland law requires only a written agreement signed by both parties. No witnesses and no notarization are legally mandated. That said, notarization is standard practice because it authenticates signatures and creates evidence of voluntariness — both useful if the prenup is challenged later. Notarization without witnesses is the typical approach. Having both attorneys present at signing carries even more enforceability weight than notarization alone, because their witness signatures directly address the "freely and understandingly" standard courts apply under the overreaching test.
8. Can you get a prenup after marriage in Maryland?
No — by definition, a prenuptial agreement must be signed before the wedding. However, Maryland recognizes postnuptial agreements under the same statutory authority, FL Art. § 8-101, which allows spouses to enter enforceable agreements relating to property and personal rights. Postnuptial agreements cover the same subjects (property division, spousal support, debt allocation) but face greater judicial scrutiny because the marital confidential relationship is already established and the consideration structure differs from a prenup. If you missed the window for a prenup, a postnup is the alternative — but expect your attorney to build in additional procedural safeguards.
9. What can't be in a prenuptial agreement in Maryland?
Maryland courts will not enforce prenup provisions that address child custody or child support — these are determined at the time of divorce based on the child's best interests, and including them can put the entire agreement at risk. Courts also reject provisions requiring illegal conduct, waiving criminal rights, or encouraging divorce. Lifestyle clauses (weight requirements, exercise mandates, religious observance) are generally unenforceable as violations of personal autonomy. Finally, any term that is unconscionable at the time of signing — meaning so extreme it shocks the conscience — will fail the substantive prong of the Cannon overreaching test.
10. Does Maryland follow the Uniform Premarital Agreement Act (UPAA)?
No. Maryland is one of roughly 20 states that has never adopted the UPAA or its 2012 revision (UPMAA). This means there is no statutory checklist for prenup validity, no codified disclosure requirement, and no statutory unconscionability standard. Everything is governed by case law — primarily Cannon v. Cannon, 384 Md. 537 (2005), which established the overreaching framework, and Stewart v. Stewart, 214 Md. App. 458 (2013), which applied it. The practical consequence: Maryland prenups depend more heavily on judicial discretion than in statutory states, making careful drafting and thorough disclosure even more important.
11. Can a Maryland prenup be overturned after signing?
Yes, but it is difficult. The party attacking the prenup bears the burden of proving a traditional contract defense (fraud, duress, coercion, mistake, undue influence, or incompetence) or proving that the enforcing party cannot satisfy the overreaching test. Courts have voided prenups presented days before the wedding with no time for review (Helal v. Helal, 2021), and where agreement terms were in a language the signing party could not read. However, in Stewart v. Stewart (2013), the court upheld a prenup signed just four days before the wedding where the wife had general knowledge of the husband's assets and retained alimony rights. The outcome is highly fact-specific. The best defense against a challenge: full disclosure, independent counsel for both sides, adequate review time, and terms that pass the substantive-commensurate-benefit test.
12. How far in advance should I sign a prenup in Maryland?
Sign 60 or more days before the wedding. Give your partner at least two weeks to review the final draft with their own attorney. Courts have voided agreements presented just days before the ceremony when the challenging party lacked time to understand the terms or consult counsel. Maryland has no statutory minimum waiting period, but the "freely and understandingly" standard from the case law means time pressure weighs heavily against enforceability. Contact an attorney 4–6 months before the wedding. The strongest approach: finalize and sign the prenup before the proposal, eliminating any argument that wedding pressure influenced the decision.
13. Can a prenup protect an inheritance in Maryland?
Yes. Inheritances are generally classified as separate property under Maryland law, but they can lose that protection if commingled with marital assets — for example, depositing inherited funds into a joint account or using them to improve a jointly titled home. A prenup can explicitly designate current and future inheritances as separate property regardless of how they are held or used during the marriage. This is especially important for second marriages where one or both spouses expect to receive family wealth and want to preserve it for children from a prior relationship. Include the inheritance expectation in your financial disclosure even if you have not yet received it.
14. Can I modify a Maryland prenup after it is signed?
Yes. Maryland treats prenuptial agreements as contracts, and contracts can be amended by mutual written agreement. Both parties must consent to the modification, and the amendment should be in writing and signed by both parties — notarization is advisable for the same evidentiary reasons as the original agreement. If circumstances change significantly during the marriage (new business, inheritance, children, career change), a written amendment or a postnuptial agreement under FL Art. § 8-101 can update the terms. Unilateral changes are not enforceable. If one party wants changes and the other refuses, the original agreement controls.
