Maine Probate Bond
Under 18-C M.R.S. §3-603, most Maine personal representatives appointed in an informal proceeding pay no bond at all — no waiver to sign, no premium to shop, nothing. That default flips for formal proceedings, where bond attaches unless the will relieves it, and it flips again if a special administrator is being appointed, the will expressly requires bond, or an interested party files a §3-605 demand. Title 18-C took effect September 1, 2019, replacing the older Title 18-A code — a lot of what still ranks online about Maine probate bonds cites the repealed statute. This page covers the current §3-603 triggers, the §3-604 amount formula, the restricted-account reduction, and what a bond actually costs once one is required.
Two proceedings, two opposite bond defaults
Most probate guides talk about bond as one universal rule per state. Maine doesn't work that way — the Probate & Family Court track you're on decides which default you start from.
Informal proceeding
Default: no bond required
Handled by the register without a hearing — built for uncontested estates. Under §3-603, bond is simply not required, unless:
- • You're being appointed special administrator
- • The will expressly requires a bond
- • An interested party files a §3-605 demand
Formal proceeding
Default: bond may be ordered
Goes before a judge, with notice to interested parties — typically a contested will, unascertained heirs, or a disputed appointment. Under §3-603, the court may order bond by court order, except bond isn't required if:
- • The will relieves the personal representative of bond
- • ...unless an interested party requests bond and the court finds it desirable
Notice the asymmetry: informal proceedings need an affirmative trigger to require bond; formal ones need an affirmative will provision (that survives a possible court override) to avoid it. Not sure which track your case is on? Our national probate bond guide covers how informal and formal proceedings work across UPC states generally.
The $5,000 demand that overrides “no bond” in an informal case
Even a clean informal appointment with no will bond clause isn't permanently bond-free. Under §3-605, “any person apparently having an interest in the estate worth in excess of $5,000, or any creditor having a claim in excess of $5,000,” can file a written demand with the register that forces bond — the same $5,000 figure Massachusetts uses in its own UPC-derived §3-605, since both states codify close to the original uniform text.
Once notice of a demand is received, the statute requires the fiduciary to suspend exercising office powers except those needed to safeguard estate assets — distributions, sales, and account closures stop — until bond is posted or the demand lapses. You then have 30 days to file a suitable bond. Miss the window and it becomes cause for removal and appointment of a successor personal representative.
The demand requirement only ends if the demanding party's own interest in the estate ends, or the bond is separately excused under §3-603 or §3-604 — a creditor who gets paid in full, for example, loses standing to keep the demand alive. Compare this to Massachusetts, where every personal representative files a bond regardless of proceeding type and the §3-605 demand instead forces sureties onto an already-filed bond, not the filing itself.
Cut the bond by locking down estate cash instead of bonding all of it
When bond is required, §3-604 doesn't just set an amount and stop there — it sets the amount using a sworn estimate, then gives the register a specific way to reduce it. If estate assets are deposited with a domestic financial institution in a manner that prevents their unauthorized disposition — a restricted or blocked account most Maine banks can set up — the register may permit the bond to be reduced by that deposited value. Money that can only leave the account with court authorization doesn't need a second layer of surety protection on top of it.
18-C M.R.S. §3-604 — bond amount with a restricted-account reduction
18-C M.R.S. §3-604. The register must also confirm the bond is executed by a corporate surety, or an individual surety secured by pledge of personal property, mortgage on real property, or other adequate security.
This only works if the deposit genuinely blocks unauthorized withdrawal — a regular checking account the fiduciary can freely draw on doesn't qualify. Ask your bank for a restricted or blocked fiduciary account before you apply, and bring the account confirmation to your bond application so we can quote the reduced figure instead of the full sworn estimate. Curious how the numbers move once you have both figures? Run them through the probate bond calculator.
What a Maine probate bond costs by estate size
There's no statutory premium rate in Maine — §3-604 sets the bond's coverage amount, not what you pay for it. The premium runs a small percentage of that sworn-estimate figure, consistent with the 0.5%–1.5% industry-standard range for probate fiduciary bonds we track nationally. Fiduciaries with strong personal credit and a straightforward estate price toward the low end; estates with real property, business interests, or credit challenges price higher.

Illustrative range based on the 0.5%–1.5% industry-standard premium band, not a Maine statutory rate
| Sworn estate estimate (§3-604 bond amount) | Strong credit, straightforward estate | Credit challenges or complex estate |
|---|---|---|
| $25,000 | ~$125–$250/yr | ~$375–$625/yr |
| $100,000 | ~$500–$1,000/yr | ~$1,500–$2,500/yr |
| $250,000 | ~$1,250–$2,500/yr | ~$3,750–$6,250/yr |
| $500,000 | ~$2,500–$5,000/yr | ~$7,500–$12,500/yr |
| $1,000,000 | ~$5,000–$10,000/yr | ~$15,000–$25,000/yr |
Figures are illustrative, applying the 0.5%–1.5% industry premium band to sample bond amounts — actual quotes depend on underwriting review of credit, estate complexity, and any §3-604 restricted-account reduction.

Same statute, 16 different registries to file with
Maine probate runs through 16 county Registries of Probate — Androscoggin, Aroostook, Cumberland, Franklin, Hancock, Kennebec, Knox, Lincoln, Oxford, Penobscot, Piscataquis, Sagadahoc, Somerset, Waldo, Washington, and York. Each has its own elected Judge of Probate and Register of Probate, and the bond is filed with whichever county register has jurisdiction over the decedent's estate — typically the county where the decedent was domiciled at death.
The §3-604 amount formula and §3-603 triggers don't change by county — Maine runs one statewide statute, not county-by-county rules. What changes is which register reviews your bond paperwork and which local form conventions apply. Tell us your county at the start and we prepare the bond your registry accepts the first time, instead of one that gets bounced back for the wrong cover sheet or acknowledgment format.
Official Maine Requirements
"Bond is not required of a personal representative appointed in informal proceedings, except upon the appointment of a special administrator, when an executor or other personal representative is appointed to administer an estate under a will containing an express requirement of bond or when bond is required under section 3-605."Maine State Legislature — Maine Revised Statutes • 18-C M.R.S. §3-603
From petition to a bond your registry will accept
Confirm your proceeding type
Informal (register-approved, no hearing) or formal (judge-approved, with notice) — this alone tells you which §3-603 default you're starting from.
Check for a §3-603 trigger
Special administrator appointment, an express will bond clause, or a §3-605 demand already on file — any one of these means bond applies even in an informal case.
File your sworn estate estimate
If bond is required and the will or court order hasn't fixed an amount, you file a sworn statement estimating the personal estate's value and expected year-one income under §3-604.
Set up a restricted account, if it helps
Depositing assets at a bank in a form that blocks unauthorized withdrawal can reduce the register-approved bond amount before you apply.

Maine probate bond questions: triggers, amounts, and filing
My estate is going through informal probate. Do I really not need a bond?
Correct, in most cases — this is the part of Maine law that trips people up, because it's the opposite of what many neighboring states do. 18-C M.R.S. §3-603 states plainly that "bond is not required of a personal representative appointed in informal proceedings," full stop, unless one of three things is true: the appointment is for a special administrator, the will contains an express bond requirement, or a §3-605 demand has been filed. If none of those apply to your informal case, there is no bond to buy — not a waived one, not a reduced one, none.
I'm being appointed as a special administrator. Does the informal-proceeding exemption apply to me?
No. §3-603 carves out special administrators by name as one of the three exceptions to the no-bond default — the statute exempts personal representatives "appointed in informal proceedings, except upon the appointment of a special administrator." Special administrators are typically appointed to protect an estate quickly, before a full personal representative is qualified, and Maine treats that emergency, less-vetted appointment as bond-worthy regardless of whether the broader case is informal or formal.
My will says no bond is needed, but this is a formal proceeding — am I safe?
Usually, but read the exact clause. §3-603 says bond "is not required of a personal representative appointed in formal proceedings" if the will relieves the requirement — but that relief evaporates "if bond has been requested by an interested party and the court is satisfied that it is desirable." So a will's no-bond clause controls only until someone with a stake in the estate asks the judge to order one anyway, and the judge agrees it's warranted. A formal proceeding puts a judge in the room in a way an informal one doesn't, which is exactly why that override only exists on the formal side.
Someone is demanding I post a bond in my informal case. What's the threshold and how long do I have?
Under §3-605, anyone "apparently having an interest in the estate worth in excess of $5,000, or any creditor having a claim in excess of $5,000," can file a written demand with the register that forces bond — regardless of proceeding type or what the will says. Once you're notified, you must "suspend exercising office powers except those needed to safeguard estate assets" until the bond is filed, and you have 30 days to post a suitable bond or it becomes cause for your removal and the appointment of a successor. The demand right ends only if the demanding party's own interest in the estate ends, or the requirement is separately excused under §3-603 or §3-604.
Can I lower my Maine bond amount by putting estate cash somewhere specific?
Yes — this is a concrete lever most fiduciaries don't know exists. §3-604 lets the register "permit the amount of the bond to be reduced by the value of assets of the estate deposited with a domestic financial institution" when that deposit is structured to prevent unauthorized withdrawal — a restricted or blocked account, essentially. If half your estate's liquid assets sit in a restricted account at a Maine bank, you can potentially cut your bond requirement roughly in half rather than bonding the full sworn estimate.
Does the county I file in change my bond amount or which form I need?
The bond amount and the governing statute are identical statewide — §3-604's sworn-estimate formula doesn't vary by county. What changes is where you file and which elected Register of Probate reviews the bond: Maine runs probate through 16 separate county Registries of Probate (Androscoggin through York), each with its own register and judge. Tell us your county up front and we prepare the bond form that specific registry accepts, rather than a generic form that gets kicked back at filing.
