Contest a Will in Maine: At a Glance
Here are the Maine facts that decide whether you can contest a will in Maine:
| Deadline to contest | 3 years after the decedent’s date of death is the outside limit for any formal testacy (will contest) proceeding — 18-C M.R.S. §3-108. If the will was already admitted through INFORMAL probate, a proceeding to contest it and to appoint the person with legal priority may be commenced within the LATER of 12 months from the informal probate or 3 years after death — 18-C M.R.S. §3-108(3). If the will is offered in a FORMAL testacy proceeding, written objections must be filed before or at the noticed hearing — 18-C M.R.S. §3-404. To vacate a formal testacy order already entered, the petition must be filed before the earlier of: entry of the order approving final distribution (or 6 months after a closing statement is filed if the estate closed by statement), or the §3-108 3-year outside limit, and in no event more than 12 months after entry of the order sought to be vacated — 18-C M.R.S. §3-412(3) |
| What starts the clock | The decedent’s date of death starts the 3-year outside clock (18-C M.R.S. §3-108). For an informally probated will, the alternative clock starts on the date of the informal probate (12 months). For a formal testacy proceeding, the clock is the notice of the hearing on the petition — objections must be filed by the hearing (18-C M.R.S. §3-403, §3-404). For vacating an entered order, the clock starts at entry of that order (18-C M.R.S. §3-412(3)) |
| Who can contest | “Interested persons” under 18-C M.R.S. §1-201 — heirs, devisees, children, spouses, domestic partners, creditors, beneficiaries, and any others having a property right in or claim against the estate, plus persons having priority for appointment as personal representative and fiduciaries representing interested persons. Section 1-201 expressly states that who counts as an interested person may vary and is determined according to the particular purpose and matter involved in the proceeding. A formal testacy proceeding is commenced by an interested person’s petition under 18-C M.R.S. §3-401 |
| No-contest clause | YES with a probable-cause exception. A provision in a will penalizing an interested person for contesting the will or instituting other proceedings relating to the estate is UNENFORCEABLE if probable cause exists for instituting the proceedings — 18-C M.R.S. §3-905. A parallel provision applies to comparable clauses under 18-C M.R.S. §2-516. So the clause is given effect only against a contest brought without probable cause |
| What the filing is called | Petition for formal testacy proceeding (a “petition for formal probate of will,” a “petition to set aside an informal probate of a will,” a “petition to prevent informal probate,” or a “petition for an order that the decedent died intestate”) filed in the county Probate Court — 18-C M.R.S. §3-401. A party responding to a will offered in formal probate files WRITTEN OBJECTIONS to the probate of the will under 18-C M.R.S. §3-404. A challenge to an order already entered is a petition for vacation or modification under 18-C M.R.S. §3-412 |
| Court | The Maine Probate Court for the county with venue (Maine has a separately administered Probate Court in each of its 16 counties, run at county-government level, not part of the Judicial Branch trial court system). Venue is set by 18-C M.R.S. §3-201. Jurisdiction over formal proceedings is under 18-C M.R.S. §1-302 / §3-401 |
| Jury trial | NO in the Probate Court — “in any proceeding under this Code, the court shall sit without a jury” (18-C M.R.S. §1-306). However, that same section provides that on timely demand by any party, a proceeding not within the exclusive jurisdiction of the Probate Court may be REMOVED for trial to the Superior Court under the procedures the Supreme Judicial Court provides by rule, where a jury may be available. You may be able to obtain a jury only through that removal route — check with the county Probate Court or a licensed Maine attorney |
| Typical cost | UNVERIFIED — no official Maine court or state bar publication states a typical dollar range for a contested will case. Filing fees are set by each county Probate Court’s fee schedule; attorney’s fees vary widely. Check with your county Probate Court or a licensed Maine attorney |
The Deadline to Contest a Will in Maine
The window is short in some states and long in others, and it is measured from a specific event rather than from the day you learned about the will. That is why the first thing to find out is the date the will was admitted and whether you received formal notice. If the deadline has not run, everything else on this page is available to you.
If it has, the remaining options are narrow and usually involve proving you never got the notice the law required.
Grounds to Contest a Will in Maine
Statutory grounds a contestant must prove under 18-C M.R.S. §3-407 — lack of testamentary intent, lack of testamentary capacity, undue influence, fraud, duress, mistake, and revocation. Improper execution / forgery are also contested, but there the proponent carries the initial burden of prima facie due execution (18-C M.R.S. §3-407; execution requirements at §2-502; forgery/fraud affecting a self-proving affidavit at §3-406)
Who has to prove what: Under 18-C M.R.S. §3-407, proponents of the will carry the burden of prima facie proof of due execution in all cases (and, if petitioners, prima facie proof of death and venue); CONTESTANTS then carry the burden of establishing lack of testamentary intent or capacity, undue influence, fraud, duress, mistake, or revocation.
Parties have the ultimate burden of persuasion on matters for which they have the initial burden. Maine does NOT apply a burden-shifting presumption of undue influence in will contests: proof of a confidential relationship permits an inference of undue influence but does not raise a presumption and does not shift the burden — In re Estate of Lewis, 2001 ME 74.
Maine case law requires a confidential relationship to be shown by clear and convincing evidence in this context. (A separate statutory presumption of undue influence, shifting the burden to the transferee, applies to lifetime transfers by elderly dependent persons under 33 M.R.S. §1022 — that is not the will-contest standard.)
Who Can Contest a Will in Maine
“Interested persons” under 18-C M.R.S. §1-201 — heirs, devisees, children, spouses, domestic partners, creditors, beneficiaries, and any others having a property right in or claim against the estate, plus persons having priority for appointment as personal representative and fiduciaries representing interested persons. Section 1-201 expressly states that who counts as an interested person may vary and is determined according to the particular purpose and matter involved in the proceeding.
A formal testacy proceeding is commenced by an interested person’s petition under 18-C M.R.S. §3-401 Being unhappy with the will is not standing; losing something because of it is. Check the earlier will and the intestate rules for Maine before filing, because they decide whether you are an interested person.
No-Contest Clauses in Maine
YES with a probable-cause exception. A provision in a will penalizing an interested person for contesting the will or instituting other proceedings relating to the estate is UNENFORCEABLE if probable cause exists for instituting the proceedings — 18-C M.R.S. §3-905. A parallel provision applies to comparable clauses under 18-C M.R.S. §2-516. So the clause is given effect only against a contest brought without probable cause
The Steps to Contest a Will in Maine
Step one is the deadline check above. Step two is evidence: the medical records around the signing date, the names of the witnesses, the drafting lawyer’s file, and the financial records that show who benefited.
Step three is the filing — Petition for formal testacy proceeding (a “petition for formal probate of will,” a “petition to set aside an informal probate of a will,” a “petition to prevent informal probate,” or a “petition for an order that the decedent died intestate”) filed in the county Probate Court — 18-C M.R.S. §3-401.
A party responding to a will offered in formal probate files WRITTEN OBJECTIONS to the probate of the will under 18-C M.R.S. §3-404. A challenge to an order already entered is a petition for vacation or modification under 18-C M.R.S. §3-412. Step four is discovery and, in most cases, a settlement conference; the small minority that reach trial are decided by the judge.
Settling Instead of Fighting
YES. Competent successors may agree among themselves in a written contract executed by all affected to alter the interests, shares, or amounts to which they are entitled under the will or under intestacy, and the personal representative must abide by the agreement, subject to the rights of creditors, taxing authorities, costs of administration, and non-party successors — 18-C M.R.S. §3-912 (private agreements among successors binding on the personal representative).
Maine courts also have discretion to refer parties to mediation; the Judicial Branch Court Alternative Dispute Resolution Service (CADRES) provides mediators (https://www.courts.maine.gov/programs/adr/index.html)
Other Maine rules: (1) Maine recodified its probate code effective September 1, 2019 — the current law is Title 18-C; the older Title 18-A citations still found online are superseded. (2) Probate Courts in Maine are COUNTY courts, one per county, separate from the Judicial Branch trial courts — filing, fees, and local practice vary by county.

(3) No jury in Probate Court; a jury is possible only by timely demand for removal to Superior Court on matters not within exclusive probate jurisdiction — 18-C M.R.S. §1-306. (4) Self-proved will presumption: a will self-proved under 18-C M.R.S. §2-503 satisfies the execution requirements WITHOUT testimony of any attesting witness, unless there is evidence of fraud or forgery affecting the acknowledgment or affidavit — 18-C M.R.S. §3-406(1).
If the will is witnessed but not notarized or self-proved, testimony of at least one attesting witness is required if that witness is in Maine, competent, and able to testify — 18-C M.R.S. §3-406(2).
(5) No presumption of undue influence from a confidential relationship in will contests — only a permissible inference, and the burden does not shift (In re Estate of Lewis, 2001 ME 74) — this is more contestant-unfavorable than many states. (6) Maine has NO ante-mortem (pre-death) will validation procedure — no such provision appears in Title 18-C; a will’s validity is litigated only after death.
(7) Extended clocks exist in narrow situations under §3-108: proceedings may be brought any time after a prior dismissal based on doubt about the fact of death; within 3 years after a conservator can establish the death of an absent or missing protected person;
and within 6 years of accrual for a personal-injury claimant without actual notice of the death (recovery limited to applicable insurance if commenced more than 3 years after death).
(8) A formal testacy order is final as to all issues the court considered or might have considered, but may be modified or vacated if the proponents of a later-discovered will were unaware of its existence at the earlier proceeding — 18-C M.R.S. §3-412
The Evidence That Wins or Loses a Will Contest
Capacity cases turn on the weeks around the signing: the medical chart, prescriptions, a dementia diagnosis, and what the drafting lawyer and the witnesses saw that day. A will signed in a lawyer’s office with two disinterested witnesses and a self-proving affidavit is hard to attack; a will signed at a kitchen table with the main beneficiary present is not.
Undue influence cases turn on the relationship — who drove the parent to the appointment, who chose the lawyer, who was in the room, and whether the new will departed sharply from earlier ones and from what the parent said to other people.
Improper execution is the narrowest ground and the cleanest: Maine sets exact witness and signature rules, and a will that misses them fails regardless of what the signer intended. Before you contest a will in Maine, gather the prior wills, the medical releases, and the names of everyone at the signing.
Most of that evidence has to be requested formally once the case is filed, and the deadline does not wait for it.
What to Expect When You Contest a Will in Maine
A will contest is a lawsuit about the document, not about fairness. When you contest a will in Maine, the court asks whether the person who signed it had capacity, signed it freely, and signed it correctly. It does not ask whether the split was reasonable. That is why the strongest cases rest on medical records and witness accounts from the weeks around the signing.
Most families who contest a will in Maine settle. Courts encourage it, many states have family settlement rules that let the heirs agree to a different division, and a settlement avoids the cost and delay of trial. The deadline, the grounds, and the no-contest clause above are the three facts that set your bargaining position before any of that begins.
