How inherited property moves in Massachusetts
Verified state rules behind the county data.Probate rules matter because they determine when a public court record appears and which inherited properties never appear in an ordinary probate case.
What changes for an heir
Massachusetts does not reassess on transfer and has no inheritance tax, but it does have an estate tax, and it shows up as a title problem rather than a holding cost. For deaths on or after January 1, 2023 an estate owes no tax where the federal taxable estate is not more than $2,000,000 (MGL c.65C section 2A(g)), and the credit against the tax is capped at $99,600 (section 2A(f)); the Department of Revenue sets the filing threshold at gross estate plus adjusted taxable gifts above $2,000,000. The computation changed again for deaths on or after August 1, 2025. At death a lien arises automatically on the Massachusetts gross estate and runs ten years from the date of death (MGL c.65C section 14(a)), but it ceases to attach to personal property sold for value by the person entitled to sell it (section 14(e)), so in practice it is real property where the lien blocks clear title. The Department of Revenue states that a release of that lien is needed to obtain clear title and sell or transfer the real estate: a Certificate Releasing Massachusetts Estate Lien where a return is due, or, below the threshold, an affidavit of the personal representative recorded in the registry of deeds.
Where probate records appear
Probate and Family Court masscourts.org, the Massachusetts Trial Court case access site. Estates and administrations are a publicly available Probate and Family Court case type; every division has cases online back to 2000 and document images back to 2009, and older files are obtained from the division where the case was filed or from a courthouse public kiosk.
Ways property can avoid ordinary probate
Revocable living trusts, including the nominee and realty trusts common in Massachusetts conveyancing, and joint tenancy or tenancy by the entirety. Voluntary administration under MGL c.190B section 3-1201 reaches personal property only. Massachusetts has not enacted a transfer-on-death deed for real property: the nonprobate transfer provisions in MGL c.190B Article VI cover contractual arrangements (section 6-101) and registration of securities in beneficiary form (sections 6-301 to 6-311).
Small-estate route
voluntary administration under MGL c.190B section 3-1201, for a decedent domiciled in Massachusetts who left an estate consisting entirely of personal property, the total of which may include a motor vehicle plus other personal property not exceeding $25,000 in value. It may be filed after 30 days from the death and only while no petition for appointment of a personal representative has been filed with the court of the county where the decedent resided. Any real estate takes the estate out of this procedure.
Timing investors should understand
The statutory floor is one year: a creditor may not hold the personal representative to answer unless the action is commenced within one year after the date of death and, before that year runs, process is served or a notice of the claim is filed with the register (MGL c.190B section 3-803(a)). Massachusetts has no publication based claim window. Informal appointment cannot issue until at least 7 days have elapsed since the death, or 30 days for a non-resident decedent (MGL c.190B section 3-307(a)). A voluntary administration statement may not be filed until 30 days after the death (section 3-1201). The Massachusetts estate tax return and payment are due nine months after the date of death, with an automatic six month extension of time to file where at least 80 percent of the tax is paid by the original due date (Department of Revenue).
