Petition to Probate a Will Requirements in Maine

Requirements one by one

Informal application or formal petition

Maine's county Probate Courts handle two ordinary tracks. An informal case is a verified application directed to the register. A formal testacy case is litigation begun by an interested person's petition for a judicial order after notice and hearing. Under 18-C M.R.S. § 3-107, probate and appointment may be combined in one proceeding, but neither request is legally required to include the other.

Section 1-201 defines an interested person broadly enough to include affected heirs, devisees, children, spouses, domestic partners, creditors, beneficiaries, appointment-priority claimants, and fiduciaries representing interested people. The Probate Court has decedent-estate jurisdiction under § 1-302. Venue under § 3-201 is the decedent's domicile county, or any county containing the nondomiciliary decedent's property. Later proceedings ordinarily remain where the first one began unless transferred under the Code.

Filing facts and original will

The informal application under 18-C M.R.S. § 3-301 states the applicant's interest; the decedent's death, age, and domicile; spouse, children, heirs, devisees, addresses, and minor ages; nonresident venue; existing representatives; notice demands; and why the filing is timely. Will probate adds the applicant's beliefs about execution, revocation, and whether this is the last will. A joined appointment application adds the proposed representative's name, address, and priority.

For informal probate, the original must already be with the court or accompany the application. The ordinary authenticated-copy substitute is a will already probated in another jurisdiction. Section 3-303 separately requires an original, apparently executed and unrevoked will for original informal probate.

A formal petition under § 3-402 requests testacy and heir determinations, imports the specified informal-application facts, and states whether the original is already with the court or accompanies the petition. If neither is true and no authenticated foreign-probate copy accompanies it, the formal petition must state the will's contents and explain why it is lost, destroyed, or unavailable.

Delivery and the three-year rule

A will custodian's duty under 18-C M.R.S. § 2-515 begins after death. The will must be delivered with reasonable promptness to someone able to secure probate or, if no such person is known, to an appropriate court. Maine supplies no fixed number of days, but a willful failure can produce damages and, after a court order, contempt.

18-C M.R.S. § 3-108 still states an ordinary three-year limit, but it is no longer an absolute bar. PL 2025, c. 168 permits a proceeding after three years when no succession or estate-administration proceeding occurred during the first three years. That late representative may possess assets only as needed to confirm successors' title; non-administration claims cannot be presented; and homestead, exempt-property, and family allowances cannot be satisfied. Other listed exceptions cover specific missing-person, contest, post-death property-control, and personal-injury settings.

Proof

For informal probate, 18-C M.R.S. § 3-303 permits a will with the apparent signatures and a compliant attestation clause to be probated without more. In other cases, the register may presume execution from the instrument or accept a sworn statement or affidavit from a person who knows the execution circumstances, whether or not that person was a witness.

In an unopposed formal case, § 3-405 permits an order on the pleadings or an open-court hearing. If execution evidence is needed, one attesting witness's affidavit or testimony is sufficient, with other evidence available when that witness proof cannot be obtained. In a contested execution dispute, § 3-406 treats a self-proved will as satisfying execution without witness testimony unless fraud or forgery evidence affects the acknowledgment or affidavit. A witnessed but non-self-proved will ordinarily requires one competent, available in-state witness, while preserving other evidence and witness affidavits.

Notice, hearing, and objections

Informal probate has no scheduled hearing, but it is not notice-free. Sections 3-306 and 3-310 require notice to demandants, nonwaiving heirs and devisees, existing representatives, and—on the appointment request—people with prior or equal appointment rights. The Department of Health and Human Services also receives notice if the decedent was at least 55. Under 18-C M.R.S. § 1-401, required notice follows the Supreme Judicial Court's rules. Maine Rule of Probate Procedure 4 uses ordinary mail and publication for a specified person whose address or whereabouts cannot be found with due diligence. 18-C M.R.S. §§ 3-302 to -303 and § 3-307 prevent informal probate or appointment before 120 hours have elapsed after death.

Formal probate has a hearing. Section 3-403 names the spouse, children, other heirs, devisees and executors in relevant wills, existing representative, notice demandants, and—when the decedent was at least 55—DHHS. Unknown people and known people with unknown addresses receive publication. M.R. Prob. P. 4 ordinarily uses restricted-delivery certified mail or personal service, and Rule 12 sets the hearing at least 14 days after the first publication or completed service on everyone served another way, whichever is later. An opponent states the objections in the pleadings under § 3-404.

Nominee, bond, and letters

The person given priority by a probated will ranks first under 18-C M.R.S. § 3-203. The appointee must be at least 18 and not found unsuitable in a formal proceeding. Section 3-601 requires acceptance of the office and any required bond before letters; § 3-103 makes issuance of letters the start of estate administration and representative authority.

Section 3-603 generally dispenses with bond in an informal appointment unless the will, special-administrator rule, or qualifying demand requires it. In a formal appointment the court may order bond, while a will's relief from bond ordinarily controls unless an interested person requests bond and the court finds it desirable. If neither will nor order fixes the amount, § 3-604 uses the estimated personal estate plus expected personal- and real-estate income for the next year. Under § 3-605, a person with an estate interest or a creditor claim over $5,000 may demand bond; failure to provide required security within 30 days after notice is cause for removal.

What trips people up

Three years is the ordinary window, not always the end of the inquiry. The 2025 amendment creates a broad late route when the first three years passed without a succession or administration proceeding, but the late representative's possession and payment powers are substantially restricted.

Informal does not mean no notice. The register may act without a hearing, but the moving party still must serve the people and agency named in §§ 3-306 and 3-310. The later information duty of an appointed representative does not replace those opening notices.

The original and copy rules depend on the route. An authenticated copy of a will probated elsewhere is an express substitute. An ordinary photocopy is not the same thing, and a lost or unavailable domestic original belongs in the formal evidentiary route.

Common questions

Must the informal application wait for a hearing?

No. Informal probate is handled by the register without a hearing, but the statutory notices still apply and the register cannot issue the probate statement before 120 hours after death.

Can a will be offered more than three years after death?

Sometimes. Section 3-108 lists several exceptions, including the current route for an estate with no succession or administration proceeding during the first three years. That route does not restore the representative's ordinary powers to possess assets, pay claims, or satisfy family protections.

Does a self-proved will eliminate every hearing or objection?

No. Self-proof addresses execution evidence. A formal proceeding still follows the notice and hearing framework, and fraud or forgery evidence affecting the acknowledgment or affidavits can prevent automatic reliance on self-proof.
