What to know:
- A Maine prenup needs little on paper: under 19-A M.R.S. §603 it must be in writing and signed by both partners, and it is enforceable without consideration; no notary or witnesses are required.
- A Maine prenup takes effect on marriage with no waiting period, and a court weighs two things if it is challenged: whether you signed voluntarily and whether you had fair financial disclosure (19-A M.R.S. §608).
- Without a prenup, a Maine court first sets apart each partner's own property, then divides the marital property in proportions it considers just, and "just" does not always mean equal (19-A M.R.S. §953).
- Hiring two attorneys in Maine commonly runs $2,100 to $7,400 for the couple at published family-law rates of $200 to $300 an hour, since each partner needs their own lawyer.
- First offers a flat-fee online prenup for couples in Maine, built around the disclosure and timing that Maine courts look at, with online notarization included.
If you are planning a wedding somewhere in Maine, whether that is a Portland waterfront or a quiet town further north, a prenup might be one of the practical items on your list alongside the venue and the guest count. It is a document that lets you and your partner decide in advance how your finances would work if the marriage ever ended, instead of leaving that to a court's own judgment. Maine saw the lowest refined divorce rate among states in 2024, at 10.0 per 1,000 married women, according to the National Center for Family & Marriage Research. A prenup is a planning tool for the couples who marry anyway and want clarity from the start.
Maine also happens to make prenups straightforward. The rules are short, the requirements are light, and you have real control over the parts that matter. Here is how it works.
Are prenups valid in Maine?
Yes. Maine has adopted the Uniform Premarital Agreement Act, a model law used across many states, and its requirements are refreshingly plain. Under 19-A M.R.S. §603, a Maine premarital agreement must be in writing and signed by both parties, and it is enforceable without consideration. That last phrase means neither partner has to give the other something of value in exchange for signing; the agreement stands on its own.
What the statute does not ask for is worth noting. Maine does not require a prenup to be notarized or witnessed to be valid. Some online content hedges on this point or gets it wrong. The statute is clear: writing plus two signatures. That is the floor.
A Maine prenup takes effect when you marry. There is no waiting period built into the law. If you want to see how Maine compares with the rest of the country, our guide on how prenuptial agreements vary across America lays out the state-by-state picture. If you are already weighing whether to put one together, a Maine prenup is well within reach.
What makes a Maine prenup enforceable?
Meeting the writing-and-signature floor makes a prenup valid. Keeping it enforceable if it is ever challenged comes down to two things a court checks.
Under 19-A M.R.S. §608, a Maine prenup is not enforceable if the challenging partner proves either that they did not sign voluntarily, or that the agreement was unconscionable when it was signed and they were not given fair financial disclosure, did not waive that disclosure in writing, and could not reasonably have known the other partner's finances. Unconscionable here means a term or agreement so unfair or one-sided that a court will not enforce it, judged as of the time it was signed rather than years later.
In plain terms, a court asks two questions. Did both partners sign of their own free will? And did each partner know what the other had? Maine's highest court, the Supreme Judicial Court, treats §608 as the controlling standard for these challenges. The reassuring part is that both of these factors are within your control. You decide how much time each partner has to read and think. You decide whether both of you lay your finances out in full. Full financial disclosure is the backbone of an enforceable agreement, which is why we walk through why disclosure matters so much in a separate guide. For the general checklist that applies in any state, see what makes a prenup enforceable.
How does Maine divide property without a prenup?
If a couple divorces in Maine without a prenup, the state's own rules step in. Maine is an equitable-distribution state, which means a court divides property based on what it considers fair rather than splitting everything down the middle.
Here is the sequence. Under 19-A M.R.S. §953, a Maine court first sets apart to each spouse that spouse's own separate property. Then it divides the marital property, meaning what the couple built during the marriage, in proportions the court considers just. And "just" does not always mean "equal." A judge weighs factors like each partner's contribution, the length of the marriage, and each person's economic circumstances, then arrives at a division that may or may not be fifty-fifty.
That uncertainty is what a prenup addresses. A Maine prenup is how a couple decides in advance which property is separate and how the rest is divided, in place of the court's judgment. You are writing the rules yourselves, before there is any dispute, while you both have full information and goodwill.
What can a Maine prenup cover?
A Maine prenup can address most of the financial questions a marriage raises. Couples commonly use one to designate which assets stay separate, how property acquired during the marriage will be treated, how debts are assigned, and whether either partner will pay or receive spousal support. If one partner is bringing a business, an inheritance, or student debt into the marriage, the prenup can spell out how those are handled.
There are limits a court will still police. A prenup cannot decide child support or child custody in advance, because those are determined by a child's best interests at the time, not by a contract signed years earlier. And a court retains the power to set aside terms that were unconscionable when signed, under the §608 standard. Within those boundaries, a well-drafted Maine prenup is designed to give both partners a clear, shared understanding of how their finances work as a married couple.
How much does a prenup cost in Maine?
Cost is where the two paths diverge sharply. The traditional route means each partner hires their own attorney, because a single lawyer cannot represent both sides of an agreement. That doubles the bill.
Hiring two attorneys for a prenup in Maine commonly runs $2,100 to $7,400 for the couple, at published Maine divorce-lawyer rates of $200 to $300 an hour. The exact figure depends on how much back and forth the drafting takes and how complex your finances are. For the broader national context on what drives prenup pricing, our guide on how much a prenup costs breaks it down.
An online flat fee is the other path. No hourly rates, no back and forth billed by the tenth of an hour, no surprises at the end. Here is the comparison side by side.
| Path | What it covers | Cost for the couple |
|---|---|---|
| Two Maine attorneys (one each) | Hourly drafting and negotiation | $2,100 to $7,400 (at $200 to $300/hour) |
| First Self-Serve (online) | Written agreement, disclosure workflow, online notarization | $649 flat for the couple |
The flat fee covers both partners. It is a fixed price for the couple, not a per-person rate.
How do you get a prenup in Maine?
The practical steps are simpler than most people expect. You and your partner each gather a full picture of your finances: assets, debts, income, anything you would want the other to know. You agree on the terms, which is often the conversation that takes the most thought. You put the agreement in writing, both sign it, and you are done. Notarizing it is optional under Maine law, though it is worth doing because a notarized signature is straightforward evidence that both partners signed.
Timing is the one piece worth planning around. Maine sets no waiting period, but how much time each partner had to read and consider the agreement matters if the prenup is ever challenged. A late signing hands a partner who later challenges the agreement an argument. Signing months ahead removes that argument entirely.
Getting a prenup in Maine online is legal and enforceable. Nothing in Maine law treats an agreement differently because of how it was produced. What matters is writing, signing, full disclosure, and enough time to review, and First's online process is built around exactly those points.
Frequently asked questions
Are prenuptial agreements enforceable in Maine?
Yes. Under Maine's Uniform Premarital Agreement Act, a prenup must be in writing and signed by both partners, and it is enforceable without consideration. A court will decline to enforce one only if a partner proves they did not sign voluntarily, or that it was unconscionable when signed without fair financial disclosure.
Does a Maine prenup have to be notarized?
No. Maine does not require a prenup to be notarized to be valid; the statute asks only that it be in writing and signed by both partners. Notarizing it is still worth doing, because a notarized signature is straightforward evidence that both partners signed. First includes online notarization at no extra cost.

Do both partners need a lawyer for a prenup in Maine?
No. Maine does not require either partner to be represented for a prenup to be valid. A court looks at whether both partners signed freely and knew what the other had. Disclosure and timing are within your control, and they are what a well-built online process is designed around.
When should we sign a prenup in Maine?
As early as you reasonably can. Maine sets no waiting period, but how much time each partner had to read and think about the agreement matters if it is ever challenged. A late signing hands a partner who later challenges the agreement an argument; signing months ahead removes it.
