Maine Probate Timeline

How long does probate take in Maine? Most estates settle in 6 to 12 months. Maine runs informal administration as the common path, and the practical floor comes from the 4-month creditor claim window that starts at the first published notice, layered on the 3-month inventory deadline after appointment. Contested estates and taxable estates run longer.

This guide maps the Maine probate timeline phase by phase, lists every statutory deadline with its citation, and explains what shortens or stretches the process. Maine estates run under Title 18-C, the Maine Uniform Probate Code that took effect September 1, 2019 and replaced the repealed Title 18-A. For the full process from filing to closing, start with the Maine probate guide.

How Long Maine Probate Takes: 6 to 12 Months

Most Maine estates that use informal administration close within 6 to 12 months from the personal representative's appointment. Here is why that range holds:

• 6 months reflects the practical minimum. The personal representative cannot safely distribute assets until the creditor claim window closes, and that window runs 4 months from the first published notice under 18-C M.R.S. § 3-801, on top of the time it takes to open the estate.
• 9 months is a common landing point for a straightforward estate with cooperative heirs, a clear will, and no real estate sale.
• 12 months or longer fits estates that sell real property, file a Maine or federal estate tax return, or face a dispute among heirs.

Formal or supervised administration adds court hearings and typically runs 9 to 18 months. A small estate collected by affidavit can finish in about 1 to 2 months. The Maine probate court of record is the county Probate Court, where the Register of Probate handles informal filings and records and the Judge of Probate decides formal and contested matters. Maine does not use a Surrogate's Court or a Register of Wills.

Maine Probate Deadlines at a Glance

These clocks do not all start on the same day. The inventory deadline runs from appointment, the published creditor window runs from first publication, and the 9-month bar and the tax returns run from the date of death. Track each start date separately.

Phase 1: Opening the Estate (Weeks 1 to 4)

Probate begins when someone files with the Probate Court in the county where the decedent lived.

Weeks 1 to 2: Gather Documents and File

• Order certified copies of the death certificate from the municipal clerk or the Maine CDC records office. The first copy costs $15 and each added copy costs $6, so order enough for the banks and agencies you will contact. Our first steps after a death in Maine guide walks through this stage.
• Locate the original will. A person who has custody of the will must deliver it with reasonable promptness after death to someone able to secure its probate or to the register of probate (18-C M.R.S. § 2-515).
• File the application to open informal probate and to appoint a personal representative.

Weeks 2 to 4: Appointment and Letters

• The register reviews the application and, for an informal estate, issues the appointment and the letters that give the personal representative authority to act.
• Maine does not require a bond by default. The will can waive it, and the statute sets when a bond applies (18-C M.R.S. §§ 3-603 to 3-606).
• The personal representative obtains certified copies of the letters for banks, brokerages, and government agencies. The 3-month inventory clock now starts.

Phase 2: Inventory and Creditor Notice (Months 1 to 4)

Two clocks run side by side during this stretch: the inventory deadline and the published creditor window.

The 3-Month Inventory

Within 3 months after appointment, the personal representative must prepare an inventory of the decedent's property, listing date-of-death fair market values and any encumbrances (18-C M.R.S. § 3-706). Maine lets the personal representative either file the inventory with the court or mail it to interested persons who ask for it. Steps that keep this on schedule:

• Notify banks, brokerages, and insurers, and request date-of-death balances.
• Catalog real estate, vehicles, and personal property, and order appraisals where value is uncertain.
• Separate probate assets from assets that pass outside probate, such as jointly held accounts and beneficiary-designated accounts.

The 4-Month Creditor Window

The personal representative publishes a notice to creditors after appointment. Creditors then have 4 months from the date of first publication to present their claims or be forever barred (18-C M.R.S. § 3-801). A creditor who receives a mailed notice gets the later of that 4-month window or 60 days after the mailing. The Maine creditor claims guide covers how to publish, whom to notify, and how to allow or disallow a claim. During this window the personal representative should hold off on distributions, because paying heirs early can expose the personal representative to liability if a valid claim arrives.

Phase 3: Claims, Taxes, and Debts (Months 4 to 9)

Once the published claim window closes, the personal representative resolves claims and turns to taxes and debts.

Resolve Claims and Pay Debts

• Allow or disallow each presented claim, and pay allowed claims in the statutory order of priority.
• Watch the 9-month ultimate non-claim bar. Under 18-C M.R.S. § 3-803, claims that arose before death are barred unless presented within the earlier of the § 3-801 notice window or 9 months after death. That 9-month cutoff applies even when no notice is published.

File the Tax Returns

• File the decedent's final federal Form 1040 and Maine Form 1040ME. These returns are due April 15 of the year after death, with an automatic 6-month extension available.
• File the Maine estate tax return, Form 706ME, only if the estate exceeds the Maine exclusion amount. The return is due 9 months after death (36 M.R.S. § 4107). The Maine exclusion has a $5,600,000 base for deaths since 2018 and is indexed for inflation, reaching $7,160,000 for 2026 deaths. Confirm the current figure with Maine Revenue Services.
• File the federal estate tax return, Form 706, only if the gross estate exceeds the federal exemption ($15,000,000 in 2026) or the estate elects portability. Form 706 is due 9 months after death (26 U.S.C. § 6075). See our federal estate tax guide for Maine estates for details.

The Surviving Spouse Deadline

A surviving spouse who wants the elective share, worth half of the marital-property portion of the augmented estate, must file the election within 9 months after death or within 6 months after the will is probated, whichever expires later (18-C M.R.S. § 2-211). The Maine surviving spouse rights guide explains the election, the homestead allowance, and the family allowance.

Phase 4: Distribution and Closing (Months 9 to 12)

The last phase moves the remaining property to the heirs and closes the estate.

• Distribute the property under the will or, if there is no will, under Maine intestacy law.
• Collect a signed receipt from each person who receives a distribution.
• Close an informal estate by filing a verified closing statement after debts, taxes, and expenses are paid and the property is distributed (18-C M.R.S. § 3-1003). The Maine probate accounting guide walks through the closing statement and the final numbers.

The personal representative is entitled to reasonable compensation. Maine sets no fixed fee schedule (18-C M.R.S. § 3-719), so the amount tracks the work the estate required. The Maine executor duties guide covers the job from appointment through closing.

The Small Estate Affidavit: A Faster Path

Not every Maine estate needs full administration. A successor can collect personal property by affidavit once 30 days have passed since death, when the value of the entire estate, wherever located and net of liens, stays under the inflation-adjusted cap. The cap starts from a $40,000 base and equals $52,500 for 2026 deaths (18-C M.R.S. § 3-1201). This path covers personal property such as bank accounts and vehicles. It does not transfer real estate. Because it skips the appointment and the published creditor window, an affidavit estate can finish in about a month or two.

What Can Delay Maine Probate

Several things push an estate past 12 months:

• Will contests. A challenge to the will means hearings before the Judge of Probate and can add 6 to 18 months.
• Real estate sales. Listing, marketing, and closing a property sale adds time that market conditions can stretch.
• Estate tax filings. A Maine 706ME or a federal 706 keeps the estate open until the return is filed and any tax is settled.
• A hard-to-find or uncooperative heir. Locating a missing heir or resolving a dispute adds court steps.
• Business interests or out-of-state property. Uncommon assets take longer to value and transfer, and property in another state may need ancillary probate there.
• Insolvent estates. When debts outrun assets, the personal representative must follow the statutory priority order, which adds care and time.

How to Keep the Estate on Schedule

You cannot erase the mandatory waiting periods, but you can avoid the delays that are within your control:

1. Open the estate early. The 3-year outer limit to begin probate (18-C M.R.S. § 3-108) is generous, but every week you wait pushes the whole schedule back.
2. Publish the creditor notice promptly. The 4-month window cannot start until the first publication runs.
3. Organize the estate's records first. Pull account statements, deeds, and titles before you build the inventory.
4. Keep heirs informed. Regular updates cut down on objections that stall the closing.
5. Bring in a licensed Maine attorney for the hard parts. A contest, an insolvent estate, or a taxable estate is worth professional help.
6. Track your Maine checklist. Our Maine estate settlement checklist lists each task and deadline in order.

Frequently Asked Questions

How long does probate take in Maine?

Most Maine estates settle in 6 to 12 months through informal administration. Formal or supervised estates, and estates with a will contest or a taxable estate, often run 9 to 18 months or longer. A qualifying small estate handled by affidavit can close in about 1 to 2 months.

Can Maine probate finish in under 4 months?

For a standard estate, no. The 4-month creditor claim window that starts at the first published notice (18-C M.R.S. § 3-801) plus the 3-month inventory deadline (§ 3-706) set a practical floor. Only the small estate affidavit path, available 30 days after death, closes faster.

Does the creditor clock run from the date of death or from the notice?

The 4-month claim window runs from the date of first publication of the notice to creditors, not from death (18-C M.R.S. § 3-801). A separate ultimate bar cuts off pre-death claims 9 months after death whether or not any notice is published (§ 3-803).

When must the personal representative file the inventory in Maine?

Within 3 months after appointment, the personal representative must prepare an inventory of the estate's property with date-of-death fair market values and any encumbrances, then file it with the court or mail it to interested persons who request it (18-C M.R.S. § 3-706).

Is there a deadline to start probate at all in Maine?

Yes. Informal and formal probate or appointment proceedings generally may not begin more than 3 years after the decedent's death (18-C M.R.S. § 3-108). Limited exceptions apply, so a family unsure about the deadline should talk to a licensed Maine attorney.

How fast is the Maine small estate affidavit?

The affidavit under 18-C M.R.S. § 3-1201 becomes available 30 days after death. It covers personal property only, not real estate, and the estate value cannot exceed the inflation-adjusted cap, which is $52,500 for 2026 deaths. Collection often wraps up within a month or two.
