Updated July 26, 2026. Quick answer: Maine sets probate compensation using “reasonable” compensation with no percentage schedule. The two numbers that decide what an estate actually pays are the fee basis and the small-estate threshold — and whether that threshold reaches real estate, which is where most published guidance goes wrong.
What probate costs in Maine
| Item | Maine |
|---|---|
| Fee model | reasonable-fee |
| What the fee is calculated on | UPC state: reasonable compensation (18-C M.R.S. §3-719); no percentage schedule. |
| Court filing fee | varies by county |
| Small-estate threshold | $40,000 base (net of liens), adjusted for inflation per 18-C M.R.S. §1-108 — collection of personal property by affidavit, 18-C M.R.S. §3-1201; 30-day wait. Current inflation-adjusted figure not confirmed this session (courts’ form AF-102 reflects the operative number). |
Why Maine has no single answer
Maine does not publish a percentage schedule that produces one number, so any source quoting you a firm figure is estimating. What the statute actually fixes is the standard: UPC state: reasonable compensation (18-C M.R.S. §3-719); no percentage schedule. That makes three things decide the bill — how many billable hours the administration takes, whether any beneficiary contests, and whether the estate qualifies for the small-estate route below and skips most of it. Get the fee basis in writing before engaging anyone.
For states that DO publish a schedule, and to compare, use the probate cost calculator.
What is the small estate limit in Maine?
$40,000 base (net of liens), adjusted for inflation per 18-C M.R.S. §1-108 — collection of personal property by affidavit, 18-C M.R.S. §3-1201; 30-day wait. Current inflation-adjusted figure not confirmed this session (courts’ form AF-102 reflects the operative number).
The small-estate route here does NOT clear real estate on its own. If the person who died owned a house in their sole name, that transfer needs a separate procedure or full probate, whatever the dollar limit says. This is the single most common mistake made about small-estate affidavits, and most cost guides omit it entirely.

If the estate is still being planned rather than settled, the usual way to keep a house out of probate entirely is a living trust, which carries its own upfront cost: whether a living trust is worth it in Maine.
Does a house have to go through probate in Maine?
Usually yes, if the house was solely owned. Because Maine’s small-estate route does not clear a solely owned house, an estate that looks small on paper can still face full administration — and the fee is usually calculated on the gross value of that house, not the equity in it. That is the single most common and most costly surprise in this area, and it is fixable in advance rather than after.

How Maine compares to the other 50
Maine’s small-estate threshold of $40,000 ranks 38 of 50 jurisdictions with a stated figure, and sits close to the national median of $51,500. The range runs from $15,000 at the bottom to $400,000 at the top, so where an estate falls relative to the line matters far more than any national “average probate cost” figure. On fee model, Maine is one of 30 of 51 jurisdictions using the reasonable-fee approach.
Death taxes in Maine, separately
Maine levies an estate tax, one of 13 jurisdictions that do. That is a different question from probate cost and is decided by different statutes, but families routinely conflate the two.
Estate tax: yes – 2026 exclusion $7,160,000 (2025: $7,000,000; 2024: $6,800,000; indexed annually); rates 8% / 10% / 12% (top 12%)
What this does not include
The figures above are the probate cost — the court and compensation side of settling an estate. They are separate from any state estate tax or inheritance tax, which are taxes on the transfer itself and are owed whether or not the estate goes through probate. Appraisal, bond premium, publication, and real-estate commissions if property is sold are additional and are not set by the fee statute.
Before you hire anyone
- Ask which statute the fee is charged under, and get the citation. In Maine the governing provisions are below.
- Ask whether the quoted fee is calculated on gross value or net of debts. Gross-value states charge on the full house value even if a mortgage covers most of it.
- Ask whether the personal representative is also claiming compensation, and on what basis.
- Ask in writing whether the estate qualifies for the small-estate route, and if a solely owned house is involved, whether that route reaches it.

Maine in the rest of the picture
Probate cost is one of four things Maine decides for a retiree and their heirs. The other three — income tax on withdrawals, estate tax, and inheritance tax — are priced separately:
- Every tax Maine charges a retiree: Maine retirement taxes
- What a move out is worth: leaving Maine

- Corridor comparison: Maine To New Hampshire
