Maine Prenuptial Agreement
Maine prenuptial agreements are governed by 19-A M.R.S. §§ 601–611. Challengers must prove either involuntary execution, OR unconscionability at signing plus all three of inadequate disclosure, no written waiver of disclosure, and lack of financial knowledge. Unconscionability alone is not enough. Spousal support waivers are enforceable with a minimum of public assistance eligibility.
Bottom line: Maine earns an A grade. UPAA consistency, execution-only unconscionability review with no second look at divorce, a tough conjunctive challenge standard, and a narrow alimony floor at public assistance eligibility give Maine prenups more certainty than most other states.

Maine UPAA 19-A M.R.S. §§ 601–611
Separate Property
All assets can remain separate property, avoiding costly divorce settlements. Joint assets and debts titled in both names can be split 50/50 according to a prenuptial agreement.
Unconscionability Single Review (Pro-Prenup)
Maine reviews prenuptial agreements for unconscionability ONLY at execution (signing), not at enforcement (divorce). This prevents courts from second-guessing agreements based on changed circumstances during marriage, providing greater certainty and discouraging litigation challenges.
Unconscionability Standard—19-A M.R.S. § 608 Two-Prong Test
A prenup is unenforceable if the challenging party proves: (1) involuntary execution due to coercion or undue pressure; OR (2) the agreement was unconscionable at execution AND (a) lacked fair and reasonable disclosure of the other's property/obligations, (b) no written waiver of disclosure, AND (c) challenging party lacked adequate knowledge of the other's finances.
Spousal Support Public Assistance Minimum
Courts may override spousal support waivers if enforcement would make one party eligible for public assistance at separation or divorce. However, courts can only require support "to the extent necessary to avoid that eligibility" under 19-A M.R.S. § 608(2).
Timing
No minimum specified, but we recommend signing the prenup 60+ days before the wedding, with both parties having 2-3 weeks to review the final version to minimize challenge risk. Reach out to an attorney at least 4-6 months before the wedding with your draft prenup. Better yet, sign the prenup before proposing.
Independent Counsel
Not required, but separate counsel dramatically strengthens enforceability if the agreement is later challenged. Maine courts closely scrutinize whether parties had opportunity for independent legal review.
Financial Disclosure
"Fair and reasonable disclosure" of property and financial obligations required under 19-A M.R.S. § 608, or written waiver. PerfectPrenup includes both.
High Burden to Challenge
Challenging party must prove either involuntary execution or unconscionability plus lack of disclosure by preponderance of evidence. Maine courts favor enforcement of prenuptial agreements but require waivers of statutory marital rights to be "clear and unmistakable."
Child Support and Custody
Child support and custody clauses are unenforceable and could undermine the entire agreement. Do not include.
Maine Prenuptial Agreement Court Cases
Hutchinson v. Gomez, 2026 ME 40
The Law Court vacated the trial court's ruling on the marital home provision, holding that the prenup's "intends to purchase" language created a binding obligation on the husband to acquire the Chandler's Wharf condominium that was the wife's sole consideration for her broader waivers, and remanded for adjudication of the breach-of-contract claim.
Riemann v. Toland, 2022 ME 13
Addressing an issue of first impression, the Law Court held that a prenuptial attorney-fee waiver is unenforceable as against public policy when applied to litigation of parental rights and responsibilities, regardless of the parties' ability to pay.
Dow v. Billing, 2020 ME 10
The Law Court affirmed that the prenup's "now owned" qualifier limited the husband's nonmarital-property waiver to assets he held at execution, so the 401(k) created during the marriage remained marital property subject to division — reinforcing that waivers of statutory marital rights must be "clear and unmistakable."
Ackerman v. Yates, 2004 ME 56
The Law Court affirmed that the parties' 1978 prenup, which addressed only property rights using terms like "estate" and "interest," did not waive spousal support, holding that broad introductory recitals cannot expand the scope of specific operative provisions.
Estate of Barrows (Barrows I), 2006 ME 143, 913 A.2d 608
The Law Court held that the parties' 1997 prenup was ambiguous as to whether it applied at death (versus only at divorce) and remanded to the Probate Court for a factual determination of the parties' intent.
Blanchard v. Blanchard, 2016 ME 140, 148 A.3d 277
Applying pre-UPAA common law to a 1986 agreement signed four days before the wedding, the Law Court affirmed enforcement of the prenup despite a substantial wealth disparity (Ronald's net worth exceeded $750,000), holding that the agreement was neither procedurally nor substantively unconscionable given Sharon's six-week review period, independent counsel, and incorporated requested changes.
Estate of Barrows (Barrows II), 2008 ME 62, 945 A.2d 1217
On remand from Barrows I, the Law Court affirmed that Kelene Barrows had effectively waived her elective share, holding that a "waiver of all rights, whenever acquired" reaches both premarital and during-marriage property even where the agreement uses different language to describe each category.
Estate of Martin, 2008 ME 7, 938 A.2d 812
The Law Court held that for premarital agreements executed after September 28, 1987, the UPAA (19-A M.R.S. §§ 601-611) supersedes the pre-UPAA common-law "fair disclosure" requirement and that prenups are construed under standard contract-construction principles.
Foley v. Ziegler, 2005 ME 117
The Law Court held that where a prenup unequivocally bars any award of spousal support, the trial court cannot order one spouse to provide health insurance to the other, because health-insurance coverage is itself a form of support that has been validly waived.
Hoag v. Dick, 2002 ME 92, 799 A.2d 391
The Law Court confirmed that premarital agreements applicable in the event of divorce are enforceable in Maine and synthesized the pre-UPAA common-law framework (Rolfe/Wilson burden-shifting on "clearly disproportionate" provisions) with the UPAA, while noting that lack of opportunity to obtain independent counsel weighs against enforceability.
5-Step Checklist: How to Sign & Execute a Prenup in Maine
Step 1: Download and read the Maine prenuptial agreement
Start with our free template. It is written for Maine-specific statutes and case law under 19-A M.R.S. §§ 601–611 (Uniform Premarital Agreement Act). 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 matrimonial or divorce lawyer in Maine
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 2–3 weeks to review the final draft and have it signed 60+ days before the wedding. Maine courts treat lack of opportunity to review and obtain independent counsel as a factor against enforcement (Hoag v. Dick) — last-minute pressure is one of the most successful challenge grounds in Maine.
Step 5: Review and sign the prenup with your attorney
Both attorneys present can serve as witnesses and notarize on the spot, satisfying all requirements in one signing ceremony. Maine does not require notarization for validity under 19-A M.R.S. § 603, but it adds evidentiary weight if challenged. We HIGHLY recommend having the prenup reviewed and signed with an attorney.
Maine Prenuptial Agreement: Frequently Asked Questions (2026)
1. Are prenups enforceable in Maine?
Yes. Maine has adopted the Uniform Premarital Agreement Act, codified at 19-A M.R.S. §§ 601–611, which governs all prenups executed on or after September 28, 1987. To be enforceable, a prenup must be in writing, signed by both parties, executed voluntarily, and not unconscionable at the time of signing. Maine courts favor enforcement and place the burden of invalidating the agreement on the challenging spouse.
2. How much does a prenup cost in Maine?
Traditional attorney-drafted prenups in Maine typically cost $2,000 to $20,000 total when both parties retain separate counsel, with Maine attorney hourly rates ranging from $200 to $350. Portland-area rates run higher than rural counties. Online services start around $599 per couple with optional attorney review add-ons.
3. Do prenups need to be notarized in Maine?
No. Maine does not require notarization for a prenup to be valid under 19-A M.R.S. § 603 — only writing and signatures from both parties are required. However, notarization is strongly recommended because it adds evidentiary weight if the agreement is later challenged and helps defeat claims of forged or coerced signatures.
4. Can a prenup waive alimony or spousal support in Maine?
Yes, with one exception. 19-A M.R.S. § 604(4) expressly permits parties to modify or eliminate spousal support, and Maine courts enforce complete waivers, including waivers of related support like health insurance (Foley v. Ziegler, 2005 ME 117). The only override is § 608(2): if enforcement would cause one spouse to qualify for public assistance, a court may require support "to the extent necessary to avoid that eligibility."
5. Can a prenup determine child custody or child support in Maine?
No. The final paragraph of 19-A M.R.S. § 604 expressly bars prenups from adversely affecting a child's right to support, and Maine courts retain exclusive best-interests jurisdiction over custody. Including such clauses is not just unenforceable — under Riemann v. Toland, 2022 ME 13, even a prenup attorney-fee waiver is void when applied to child-related litigation.
6. How long before the wedding should you sign a prenup in Maine?
Maine has no statutory waiting period, but best practice is signing 60+ days before the wedding with 2–3 weeks of review time. Maine courts treat lack of review opportunity as a factor against enforcement (Hoag v. Dick, 2002 ME 92). Blanchard v. Blanchard, 2016 ME 140, upheld a prenup signed four days before the wedding because the wife had a six-week review window — review time matters more than signing-day proximity.
7. Do both parties need a lawyer for a prenup in Maine?
No, independent counsel is not statutorily required. However, both parties having separate attorneys is the single strongest factor supporting enforceability — the Law Court has flagged dual representation as supporting enforcement in Blanchard, Hutchinson v. Gomez, and Riemann, while flagging absence of counsel as a factor against enforcement in Hoag.
8. What makes a prenup invalid in Maine?
Under 19-A M.R.S. § 608, a prenup is unenforceable only if the challenger proves: (1) involuntary execution due to coercion or duress; OR (2) the agreement was unconscionable at execution AND the challenger lacked fair financial disclosure, did not waive disclosure in writing, and could not have had adequate knowledge of the other's finances. Wealth disparity alone is not enough — the agreement must "shock the conscience" (Blanchard).
9. Does Maine review prenups for fairness at the time of divorce?
No. Maine reviews unconscionability ONLY at execution, not at enforcement. 19-A M.R.S. § 608(1)(B) anchors the inquiry to whether the agreement was "unconscionable when it was executed," and § 608(3) makes unconscionability a question of law for the court. Maine is not among the fourteen states that permit substantive-fairness review at divorce, which makes Maine prenups more enforceable than precedent from before 1987.
10. Can a prenup protect a business or inheritance in Maine?
Yes. 19-A M.R.S. § 604(1) permits parties to contract regarding "any of the property of either or both of them whenever and wherever acquired or located," including business interests, future inheritances, and appreciation during the marriage. Without a prenup, Maine's equitable distribution statute (19-A M.R.S. § 953) gives judges broad discretion to divide marital property — a prenup is the only way to lock in a fixed outcome.
11. What financial disclosure is required for a Maine prenup?
19-A M.R.S. § 608(1)(B) requires "fair and reasonable disclosure" of property and financial obligations OR a written waiver of disclosure. Best practice is to do both: attach a comprehensive asset/liability schedule listing all assets, debts, income, retirement accounts, and business interests, AND include a written waiver clause. Note that disclosure failure alone does not invalidate a prenup in Maine — the agreement must also be unconscionable.
12. Can a prenup be modified or revoked after marriage in Maine?
Yes. 19-A M.R.S. § 607 allows parties to amend or revoke a prenup after marriage by signing a written amendment, enforceable without consideration. Oral modifications have no legal effect. One Maine quirk: prenups executed before October 1, 1993 automatically become void 18 months after the parties have or adopt a minor child unless re-affirmed in writing — but this rule does NOT apply to any prenup executed on or after October 1, 1993.
