Massachusetts charges the same $375 to open an estate, then prices the accounts by size and by year
G.L. c. 262, § 40 enumerates the fees of the registers of the probate and family court, and it flattens the opening step. A single $375 fee covers a petition for formal probate of a will, an adjudication of intestacy and appointment of a personal representative, a formal appointment of a successor personal representative, supervised administration, an informal probate of a will and/or appointment of a personal representative, and an informal appointment of a successor. Choosing the informal route does not save a filing fee in Massachusetts — it saves time and notice work.
What is not flat is the accounting. The fee for filing an account turns on the gross value shown in Schedule A and, above a point, is charged for each year or fraction of a year the account covers. There is no fee where the gross value accounted for is $1,000 or less. Between $1,000 and $10,000 the fee is $75, and the statute caps the total at $170 "regardless of the time covered by the account."
Above $10,000 the cap disappears and the per-year charge begins: $100 a year from $10,000 to $100,000; $150 a year above $100,000 to $500,000; $200 a year above $500,000 to $1,000,000; $400 a year above $1,000,000 to $2,000,000; $750 a year above $2,000,000 to $5,000,000; $1,500 a year above $5,000,000 to $7,500,000; $2,500 a year above $7,500,000 to $10,000,000; and $3,500 a year above $10,000,000. A slow estate is a more expensive estate here in a way the opening fee never signals — a five-year administration of a $600,000 estate carries five $200 charges, not one.
Selling property is priced on the same sliding logic: a petition or application for sale of real or personal estate by a fiduciary costs $100 where the gross value accounted for is $100,000 or less, $250 up to $250,000, $500 up to $500,000, $750 up to $1,000,000, and $1,000 above that. Petitions for leave to lease or to mortgage real estate are $75 each, removal of a fiduciary is $100, a subsequent bond or a petition for a new bond, discharge, modification or reduction of surety is $75, and a contempt summons is $5. The section also lists the filings that carry no fee at all, including the appointment of a guardian and the resignation of any fiduciary.
