Maine Probate Court: How the 16-County System Works
Most states run their probate systems through a centralized court structure. Maine does not. The state operates 16 independent, county-run probate registries, each presided over by an elected, part-time judge. If you need to settle an estate in Maine, the first thing to understand is that you are not dealing with one system — you are dealing with whichever of those 16 registries has jurisdiction over where the decedent was domiciled at death.
That distinction matters immediately. Filing in the wrong county wastes time, delays your Letters of Authority, and creates complications for every downstream task: transferring real estate, closing bank accounts, and notifying creditors.
Which Maine Probate Court Has Jurisdiction
Jurisdiction follows the decedent's domicile — the county where they lived at the time of death. If your parent owned a camp in Aroostook but lived in Portland, the Cumberland County Probate Court handles the estate. The out-of-state camp property is dealt with in that proceeding.
Maine's 16 county probate courts are:
- Cumberland County Probate Court (Portland) — the busiest court in the state, serving Maine's largest population center. The Cumberland County Registry of Deeds also adopted the new flat $40-per-document recording fee effective January 1, 2026, ending the old per-page calculation.
- Penobscot County Probate Court (Bangor) — serves the second-largest metro area. Handles a large volume of informal probate filings for uncomplicated estates.
- York County Probate Court (Alfred) — covers southern Maine's coastal communities, including Kennebunk and Saco.
- Kennebec, Somerset, Androscoggin, Oxford, Franklin, Waldo, Knox, Lincoln, Sagadahoc, Hancock, Washington, Piscataquis, Aroostook — each operates independently.
Every registry runs on the same underlying statute — Maine Revised Statutes Title 18-C (the Maine Uniform Probate Code) — but local administrative practices, scheduling, and fee collection vary. Calling your specific registry before filing avoids surprises.
The Two Main Probate Tracks
Maine's Uniform Probate Code gives families a choice between informal and formal probate. Most uncomplicated estates take the informal track.
Informal probate is an administrative process handled by the Register of Probate, not a judge. The personal representative files an Application for Informal Probate (Form DE-201(I)), and if the paperwork is in order, the Register issues Letters of Authority without scheduling a hearing. This is the default route for estates where no one contests the will and there are no creditor disputes.
Formal probate requires a court hearing before a judge. It applies when the will is contested, when there is doubt about whether a will is valid, when the nominated personal representative is disputed, or when the estate presents complex title issues — common with older rural Maine properties where historical deeds were never properly recorded.
There is also voluntary administration (also called small estate affidavit), available when the gross probate estate is under $52,500 (the 2026 inflation-adjusted threshold) and consists only of personal property with no real estate. This avoids the probate court entirely. See the Maine small estate affidavit guide for the mechanics.
What It Costs to File
Probate court filing fees in Maine are tiered by estate value under 18-C M.R.S. § 1-602. These are the current brackets:
| Estate Value | Filing Fee |
|---|---|
| $10,000 and under | $40 |
| $10,001 – $20,000 | $60 |
| $20,001 – $30,000 | $75 |
| $30,001 – $40,000 | $95 |
| $40,001 – $50,000 | $125 |
| $50,001 – $75,000 | $190 |
| $75,001 – $100,000 | $250 |
| $100,001 – $150,000 | $325 |
| $150,001 – $200,000 | $375 |
| $200,001 – $250,000 | $450 |
| Over $2,000,000 | $1,200 (plus $250 per $500k) |
These fees are subject to CPI adjustments. Verify the current schedule with your specific county registry before filing.

What Happens After You File
Once the Register of Probate reviews the application and issues Letters of Authority, the personal representative has legal power to act. From that point, the Maine Uniform Probate Code imposes a strict chronological compliance chain:
- Within 30 days of probating the will: The Register must notify all devisees by mail that devises have been made to them.
- Within 3 months of appointment: The personal representative must compile an inventory of the estate (Form DE-405) listing every asset and its fair market value at the date of death.
- Upon appointment: The personal representative publishes a Notice to Creditors in a newspaper of general circulation in the decedent's county, once per week for two consecutive weeks. This publication starts the four-month creditor claim window.
- Six months after appointment, nine months after death: The earliest a personal representative can file Form DE-602 (Sworn Statement) to close the estate under informal proceedings.
The One Process Every Maine Estate Needs
Whether or not the gross estate approaches the $7,160,000 estate tax exclusion for 2026, Maine places an automatic lien on all real property at the moment of death. This lien does not disappear on its own. Before selling or transferring the family home, the personal representative must file Form 700-SOV (Statement of Value) with Maine Revenue Services to obtain a Certificate of Discharge of Estate Tax Lien. That certificate must then be recorded at the county Registry of Deeds — at the flat $40 fee effective January 1, 2026.
This step surprises families who assume a modest estate has nothing to do with estate taxes. The lien applies regardless of estate size. Skipping it means the title company blocks the closing.
What the 16-County System Means in Practice
Because each registry operates independently, the same form can have different margin requirements or submission preferences across counties. Knox County and Cumberland County may handle informal filings identically on paper but differ in how quickly they process applications during busy months. Some registries still accept paper filings only; others have adopted the ICON/EZ-Filing digital docketing system.
If you are an out-of-state executor managing a Maine estate remotely — which is common for families of people who retire to Maine's coast or interior — this fragmentation is the primary friction point. A probate attorney in Maine will know the local registry clerk by name. A first-time executor will not.
For estates with no contested assets, no real property complications, and a total gross value under the small estate threshold, the formal probate system may not be necessary at all. For everyone else, understanding which of the 16 county registries handles your case — and calling them early — is the first practical step.
