Maine Will Contests

How to contest a will in Maine: the grounds, who has standing, filing a formal testacy case before the Judge of Probate, and the deadline under Title 18-C.

By Settled Editorial

A Maine will contest is a formal court challenge that asks a Judge of Probate to decide whether the document admitted to probate is really the decedent's valid will. You cannot bring one just because you dislike how the estate was divided. The challenge has to rest on a legal ground the statute allows, you need standing as an interested person, and you have to file within the deadline Maine's probate code sets. This guide covers the grounds, who can file, where and when, no-contest clauses, and what the process looks like.

Maine handles a will challenge as a formal testacy proceeding under Title 18-C of the Maine Revised Statutes (18-C M.R.S. section 3-401). Most Maine wills are never contested. When the facts raise a real concern, such as a caregiver who appeared late and took most of the estate, a signing during serious illness, or a signature that looks wrong, a formal testacy proceeding is the mechanism Maine law provides. A good place to start is the Maine will requirements guide, which covers the rules the will had to meet in the first place.

What a Will Contest Is (and Is Not)

A will contest asks the court to declare that the will, or part of it, is invalid. Win the challenge and the admitted will is set aside, so the estate passes either under an earlier valid will or, if there is none, under Maine's intestate succession rules.

A contest is the wrong tool in a few common situations. It is not for a person who simply expected more, who dislikes how the property was split, or who thinks the personal representative is handling the estate poorly. That last complaint is aimed at the fiduciary, not the will, and you raise it through the accounting and administration process rather than by attacking the document. The Maine executor duties guide explains what a personal representative has to do and how their conduct gets reviewed. For how an estate moves through the Probate Court overall, see the Maine probate guide.

Who Can Contest a Will in Maine

Only an interested person can bring a formal testacy proceeding. That means someone with a real financial stake, a person who would receive more if the will were set aside. The most common contestants are:

  • Heirs at law. People who would inherit under Maine's intestate succession statute if there were no valid will. That group starts with the surviving spouse and children and reaches out to parents, siblings, and more distant relatives, depending on who survives.
  • Beneficiaries under a prior will. If an earlier will left you more than the one admitted to probate, you have a stake in setting the later document aside.
  • Beneficiaries named in the contested will, usually when an earlier version treated them better.

Friends, distant relatives who would not inherit under intestacy, and charities named in no version of the will generally lack standing. The test is direct: would you actually be better off financially if the will were declared invalid? Where the answer is no, the court will not hear the challenge.

A surviving spouse also has a separate elective-share right that does not depend on winning a contest. That is its own remedy under Title 18-C, and a spouse who was left little may reach a better result through the elective share than through litigation over the will.

The Grounds for Contesting a Will in Maine

Maine does not let a court throw out a will on a hunch. In a contested case, the person defending the will (the proponent) has to make out a prima facie case of due execution, and the contestant has to prove one of the grounds the statute allows. Under 18-C M.R.S. section 3-407, contestants carry the burden of establishing lack of testamentary intent or capacity, undue influence, fraud, duress, mistake, or revocation. Each side has to prove the points it raises by a preponderance of the evidence, meaning more likely than not.

Here is what those grounds mean in plain terms.

Lack of Testamentary Capacity or Intent

Testamentary capacity means the person had enough mental ability to make a will when they signed it. Maine measures capacity at the moment of signing, not before or after. A person can have an off-and-on condition and still sign a valid will during a clear period. To have capacity, the person generally had to understand that they were making a will, have a rough sense of what they owned, know the family members who would ordinarily inherit, and understand how the will gave their property away.

Testamentary intent is a related idea: the signer actually meant the document to serve as a will. A contest on these grounds usually leans on medical records from around the signing date, statements from people who saw the person then, and, in harder cases, a physician or geriatric specialist who can speak to mental state.

Undue Influence

Undue influence is the ground raised most often. It happens when someone pressures or controls the will-maker enough to replace that person's real wishes with their own. Courts look at whether the influencer had a close or fiduciary relationship with the decedent, had the chance to apply pressure, took part in getting the will made, and ended up with an outsized share. Red flags include a signer who was isolated from family, a companion or caregiver who arrived shortly before the will changed, and a beneficiary who picked the drafting attorney or sat in on the signing.

Fraud, Duress, and Mistake

Fraud means the will-maker was deceived in a way that shaped the document. One version is a lie that changes the plan, such as convincing the signer that a child had cut off contact so the signer disinherits that child. Another is a trick about the paper itself, such as telling the signer they are signing a power of attorney when the document is actually a will. Duress means the will was procured by threats or force. Mistake covers a will that does not say what the signer believed it said. Forged signatures fall in this family too, and those cases often turn on a document examiner comparing the signature with known samples.

Improper Execution and Revocation

A will has to be executed the way Maine law requires, and a will can be revoked. If the proponent cannot show the will was properly signed and witnessed, the document fails, so a signing defect is really the flip side of the proponent's execution burden. Revocation is a separate ground: a later will or a valid act of revocation can cancel the document offered for probate. For the signing formalities themselves, including witnesses and self-proving affidavits, see the Maine will requirements guide.

How Execution Is Proved in a Contested Case

Maine gives self-proved wills a real advantage in a fight. Under 18-C M.R.S. section 3-406, a will that is self-proved satisfies the execution requirements without any attesting witness having to testify, unless there is evidence of fraud or forgery in connection with the proving affidavit. When the will was witnessed but not self-proved, the testimony of at least one attesting witness is required to establish proper execution if that witness is in Maine, competent, and able to testify. Execution can also be shown by other evidence, and an attestation clause signed by the witnesses raises a rebuttable presumption that the signing happened the way the clause recites. That is one reason a self-proving affidavit matters so much: it takes the routine question of due execution off the table and forces the contestant to fight on capacity, influence, or fraud instead.

The Deadline to Contest a Maine Will

Maine gives you more time than many states, but the clock is real. Under 18-C M.R.S. section 3-108, a proceeding to contest an informally probated will may be commenced within the later of 12 months from the informal probate or 3 years from the decedent's death. That same section sets an ultimate time limit of 3 years after death for starting probate and testacy proceedings, with a handful of narrow exceptions written into the statute.

What this means for most families: many Maine wills are admitted through informal probate handled by the Register of Probate, and the window to challenge one runs to whichever comes later, a year after that informal probate or three years after the death. A longer deadline is not a reason to wait. Witnesses move and forget, medical records get harder to pull, and a personal representative may distribute assets in the meantime. Anyone weighing a real challenge should act while the evidence is fresh. For how these dates fit alongside the other estate deadlines, see the Maine probate timeline guide.

Where and How You File

You bring a will contest as a formal testacy proceeding in the Probate Court for the county handling the estate. Maine has a Probate Court in each of its 16 counties, each presided over by an elected Judge of Probate. You can find the right court through the Maine court directory.

The proceeding starts with a petition. Under 18-C M.R.S. section 3-401, an interested person can ask the court to probate a will, to set aside an informal probate, or to declare that the decedent died intestate. A party who opposes the will has to spell out the objections in their pleadings under 18-C M.R.S. section 3-404, so vague dissatisfaction is not enough. From there the case moves like other civil litigation: notice to the interested persons, discovery such as depositions and records requests, and a hearing before the Judge of Probate. Many contests settle before a hearing because the cost and family strain of a full fight are high.

No-Contest (In Terrorem) Clauses in Maine

Some wills include a no-contest clause, also called an in terrorem clause, that tries to cut off any beneficiary who challenges the will. Maine limits how far that goes. Under 18-C M.R.S. section 3-905, a provision that penalizes an interested person for contesting the will or bringing other proceedings about the estate is unenforceable if probable cause exists for starting the proceeding.

In practical terms, a beneficiary who challenges a will in good faith, with a reasonable basis, does not automatically forfeit an inheritance just because the challenge fails. A challenge filed with no real basis is a different story, and the clause can apply. Because probable cause is a fact question, anyone facing a no-contest clause should weigh the strength of the evidence carefully before filing.

What Happens If a Contest Succeeds

If the court sets the will aside, the estate does not vanish. It passes under the next controlling document or rule. When there is an earlier valid will, the estate follows that document. When there is no earlier will, the estate passes under Maine's intestate succession statute, which names the heirs in order. A court can also invalidate only part of a will, such as a single gift tainted by undue influence, and leave the rest standing.

Weighing the Cost and Whether to File

Will contests are slow and expensive, and they can divide a family for good. Even a fairly clean case can run a year or more and reach well into five figures in attorney fees, plus costs for experts, depositions, and records, and relatives often testify under oath about a loved one's mind and private affairs. Before filing, it helps to answer a few questions honestly:

  • Do you have standing? Would you truly receive more if the will were set aside?
  • Do you have a real ground? Is there evidence of incapacity, undue influence, fraud, duress, or a signing defect, and not just disappointment?
  • Is there a no-contest clause, and how strong is your good-faith basis under the probable-cause test?
  • Is the likely recovery worth the cost and the strain, and could a negotiated settlement resolve it faster and for less?

A licensed Maine probate attorney can look at the records, tell you whether a ground holds up, and confirm the current deadline for your case.

Common Questions

How long do I have to contest a will in Maine?

Under 18-C M.R.S. section 3-108, a contest of an informally probated will may be brought within the later of 12 months from the informal probate or 3 years from the decedent's death, and the code sets an outer limit of 3 years after death for probate and testacy proceedings, subject to narrow statutory exceptions.

Can I contest a will if I am not named in it?

Yes, if you are an interested person, meaning you would inherit under Maine's intestate succession rules or under an earlier will. The question is whether you would be better off financially if the will were set aside.

What grounds can I raise in Maine?

Under 18-C M.R.S. section 3-407, a contestant can try to prove lack of testamentary intent or capacity, undue influence, fraud, duress, mistake, or revocation. The proponent, in turn, has to establish that the will was properly executed.

Does a no-contest clause mean I lose everything if I challenge the will?

Not automatically. Under 18-C M.R.S. section 3-905, a no-contest clause is unenforceable if probable cause exists for bringing the challenge, so a good-faith contest with a reasonable basis does not trigger the forfeiture.
