Maine Probate Court: Jurisdiction, Process, and Key Filings

Maine Probate Court operates as a county-level court system with exclusive jurisdiction over estates, guardianships, conservatorships, adoptions, and trusts. The court's authority derives from Title 18-C of the Maine Revised Statutes, the Maine Uniform Probate Code, which took effect on July 1, 2019, replacing the prior statutory framework. Understanding the court's jurisdictional scope, filing requirements, and procedural structure is essential for executors, heirs, guardians, attorneys, and any party with a legal interest in decedent estates or protected persons in Maine.

Definition and scope

Maine Probate Court is not a unified statewide tribunal. Maine operates 16 county probate courts, each presided over by a separately elected Probate Judge (Maine Judicial Branch). This county-based structure means that venue — the correct court to file in — is determined by the county in which the decedent was domiciled at the time of death, or the county in which a minor or incapacitated person resides.

The court's subject-matter jurisdiction under Title 18-C of the Maine Revised Statutes includes:

• Probate of wills and determination of intestate succession
• Administration of decedent estates (supervised and unsupervised)
• Appointment and oversight of personal representatives
• Guardianship and conservatorship of minors and adults
• Adoption proceedings
• Formal and informal trust administration
• Name changes in certain circumstances

Scope and coverage for this page is limited to Maine state probate jurisdiction. Federal courts do not exercise probate jurisdiction as a general rule — a boundary the U.S. Supreme Court affirmed in Marshall v. Marshall, 547 U.S. 293 (2006). Matters involving federally recognized tribal members and trust property held by the federal government for tribal nations may implicate separate jurisdictional frameworks; see Maine Tribal Law and State Jurisdiction for that boundary. Interstate estate matters involving real property located in multiple states require ancillary probate proceedings in each relevant state and are not fully resolved by Maine proceedings alone.

How it works

Maine's probate process operates along two parallel tracks under the Maine Uniform Probate Code: informal proceedings and formal proceedings. The distinction is procedurally significant and determines the level of judicial supervision.

Informal proceedings are administrative in nature. A Probate Registrar — not a judge — reviews and approves routine petitions without a hearing. Informal probate is available when the will is uncontested, the estate is straightforward, and no interested parties object.

Formal proceedings require a judicial hearing before the Probate Judge. These are mandatory when a will is contested, a personal representative appointment is disputed, or supervised administration is requested by any interested party.

Standard probate timeline and filing sequence:

1. File the petition for probate — submitted to the Probate Court in the county of domicile within a reasonable time after death; Maine law does not impose a strict filing deadline but the 3-year statute of limitations on creditor claims creates practical urgency (Title 18-C §3-803).
2. Appointment of personal representative — informal appointment issued by the Registrar; formal appointment requires a judge's order after notice to heirs.
3. Inventory and appraisal — the personal representative files a sworn inventory within 3 months of appointment, listing all probate assets at fair market value.
4. Notice to creditors — published once per week for 3 consecutive weeks in a newspaper of general circulation in the county; creditors then have 4 months from first publication to file claims (Title 18-C §3-801).
5. Payment of debts and taxes — the estate pays valid claims in statutory priority order before any distribution to heirs.
6. Final accounting and closing — the personal representative files a sworn statement of account; informal closing is by sworn statement, formal closing requires a court order.

Filing fees are set by individual county probate courts within limits established by statute. For a breakdown of associated costs, see Maine Court Filing Fees and Costs.

Common scenarios

Intestate succession — when a decedent dies without a valid will, Title 18-C §§2-101 through 2-122 govern distribution. A surviving spouse receives the entire estate if no descendants or parents survive; otherwise the share is apportioned by formula. The Probate Court appoints an administrator (rather than an executor) to manage the estate.

Small or insolvent estates — Maine provides a simplified procedure for estates where the total probate value does not exceed $40,000 (the homestead allowance plus exempt property allowance plus one year of family maintenance). A surviving spouse or children may collect assets directly by sworn affidavit without full probate administration (Title 18-C §3-1201).

Guardianship of an incapacitated adult — a petitioner files in the county where the proposed ward resides. The court appoints a visitor to investigate and report, and the alleged incapacitated person has the right to counsel. A guardian ad litem may be appointed separately. The court issues the least restrictive guardianship order consistent with the person's needs.

Testamentary trusts — trusts created by will fall under probate court jurisdiction during estate administration. Standalone revocable living trusts generally do not require probate, which is a primary reason estate planners recommend them; see Maine Estate Planning Legal Framework for the planning dimension.

Will contests — formal objections to the validity of a will must be filed before the appointment of a personal representative in informal proceedings becomes final, or within the contest period established after formal probate. Grounds include lack of testamentary capacity, undue influence, fraud, and improper execution under Title 18-C §2-502.

Decision boundaries

The Probate Court's jurisdiction is exclusive but bounded. Several adjacent matters fall to other courts or agencies:

Probate vs. non-probate assets is a critical classification boundary. Assets that pass outside the probate estate — including jointly held property with right of survivorship, beneficiary-designated accounts (life insurance, IRAs, 401(k) plans), and assets held in a revocable living trust — are not subject to Probate Court administration and do not appear in probate inventory. The personal representative has no authority over these assets. This distinction directly affects creditor access: non-probate assets generally pass free of estate creditor claims unless a specific statute applies.

Appeals from Probate Court decisions go to the Maine Superior Court, not to the District Court. The Superior Court conducts a de novo hearing on the record in most circumstances, giving the appeal a fresh review rather than a deferential standard. Further appeals proceed to the Maine Law Court (the state's highest court). The full appellate structure is described in Maine Appellate Process.
