Out-of-State Property in Massachusetts Probate: Ancillary Probate Explained

Probate jurisdiction follows the property, not the person. When a Massachusetts resident dies owning real estate in Florida, or when a Florida resident dies owning a vacation home on Cape Cod, the estate doesn't get to choose one convenient state and consolidate everything. Each state where real property sits has to deal with it separately.

This isn't a loophole or a bureaucratic quirk — it's a foundational principle of property law. Real estate is governed by the law of the state where it physically sits. No probate court in Massachusetts can transfer title to land in South Carolina, and no probate court in South Carolina can transfer title to a condo in Boston.

The practical consequence is a second probate proceeding called ancillary probate.

What Ancillary Probate Means

Ancillary probate is a secondary proceeding filed in a state where the decedent owned real property but was not domiciled (did not live) at the time of death. The primary (domiciliary) probate is filed in the decedent's home state.

Scenario 1: Massachusetts resident who owned property in another state. The primary probate is filed in Massachusetts. For each additional state where real estate was held — a Florida condo, a New Hampshire cabin, a Vermont ski property — an ancillary probate must be filed in that state, following that state's procedural rules, paying that state's filing fees, and dealing with that state's court clerks.

Scenario 2: Non-Massachusetts resident who owned real estate in Massachusetts. The primary probate is filed in the decedent's home state. The Personal Representative or a designated agent then files an ancillary probate in the Massachusetts Probate and Family Court in the county where the Massachusetts property is located.

Personal property (bank accounts, investment accounts, vehicles) is governed by the law of the decedent's domicile. Real property is governed by the law of the state where it's located. This is why a Massachusetts resident's checking accounts go through Massachusetts probate while their Georgia vacation home requires a Georgia ancillary proceeding.

Filing Ancillary Probate in Massachusetts

If a non-Massachusetts resident died owning real estate in the Commonwealth, the ancillary probate must be filed in the Probate and Family Court in the county where the property is located — not where the decedent lived, and not where the Personal Representative lives.

The filing requires:

• An authenticated copy of the foreign (out-of-state) will that was admitted to probate in the home state
• An authenticated copy of the appointment of the Personal Representative from the home state court
• The standard Massachusetts probate petition (MPC 150 for informal or MPC 160 for formal)
• A certified death certificate
• Massachusetts-specific forms (MPC 162, MPC 163, etc.) completed for the Massachusetts proceedings

The authentication of foreign court documents is handled through a process called exemplification — a certified copy issued under seal by the originating court that establishes the document's validity for use in another jurisdiction. Getting these authenticated copies can take two to four weeks depending on the originating state's court processing times, so this is worth initiating immediately after the primary probate is opened.

The Massachusetts court will review the foreign appointment and the will. If everything is in order, the magistrate (for informal proceedings) or a judge (for formal proceedings) will recognize the appointment and issue Massachusetts Letters of Authority, which are then used to transfer the Massachusetts real estate.

The Massachusetts Estate Tax Wrinkle for Non-Residents

Non-Massachusetts residents who owned real estate in Massachusetts face a specific estate tax issue that catches many executors off guard.

Massachusetts imposes an estate tax on Massachusetts-situated real estate owned by non-residents. If the Massachusetts real property is large enough — or if the decedent's overall estate, prorated to include the Massachusetts real estate, exceeds the $2,000,000 threshold — a Massachusetts estate tax return (Form M-706) may be required even though the decedent never lived in Massachusetts.

Additionally, regardless of whether any Massachusetts estate tax is owed, Massachusetts law automatically attaches a ten-year estate tax lien on all real estate situated within the Commonwealth upon the owner's death. To transfer or sell the Massachusetts property, the Personal Representative must either:

• File a Massachusetts estate tax return and obtain a Certificate Releasing Massachusetts Estate Tax Lien from the Department of Revenue, or
• File an Affidavit of No Estate Tax Due with the county Registry of Deeds (under G.L. c. 65C, § 14(a)) if the estate falls below the threshold

Neither step happens automatically. The title to the Massachusetts property remains clouded by this lien until one of these documents is recorded at the Registry of Deeds. A buyer's title insurance company will catch it, and the real estate transaction will not close until the lien is cleared.

For Massachusetts Residents: Managing Out-of-State Properties

When a Massachusetts resident dies owning property in other states, the Massachusetts estate handles everything within the Commonwealth. The Personal Representative then has to open separate ancillary probate proceedings in each additional state.

A few practical realities:

Each state has its own timeline and rules. Some states have simplified ancillary procedures (especially for small parcels), while others require a full probate proceeding mirroring their domestic process. States like Florida have their own expedited ancillary administration rules for non-residents. The Personal Representative typically needs to retain local counsel in each state where ancillary probate is required.

Massachusetts estate tax still looks at the full picture. For the Massachusetts Form M-706, the state taxes the full value of the gross estate (including out-of-state assets) if the decedent was a Massachusetts resident, but then applies a formula to apportion the tax to only the Massachusetts-located assets. Recent 2024 amendments to Massachusetts estate tax law altered how this apportionment works for real and tangible personal property located outside Massachusetts. If the estate approaches the $2,000,000 threshold and includes significant out-of-state real estate, a CPA experienced in Massachusetts estate tax law should review the Form M-706 calculation before filing.

Personal property does not trigger ancillary probate. If a Massachusetts resident had a bank account in Nevada, that account passes through Massachusetts probate using Letters of Authority — Nevada ancillary probate is not required. Only real estate (and in some states, tangible personal property like boats or aircraft) requires an ancillary proceeding in the state where it's physically located.

Practical Steps for Multi-State Estates

1. Identify all real estate owned by the decedent in any state. Pull the deed records for any property you're aware of, and run a search if there's any uncertainty. Real estate transactions create public records — they can be found.

2. Confirm domicile. Where was the decedent legally domiciled at the time of death? This determines which state receives the primary probate and which states receive ancillary proceedings.

3. Open primary probate first. The ancillary proceedings in other states need authenticated copies of the primary court's documents. Getting the Massachusetts primary probate or the foreign primary probate moving first creates the documentary foundation for everything else.

4. Contact the Massachusetts Registry of Deeds early. If there's a Massachusetts property involved — either as the ancillary state or as the primary state — contact the specific county Registry of Deeds to confirm their current requirements and recording fees for estate-related documents. Fees vary slightly by county (generally $105–$155 per instrument), and the formatting requirements for deeds, affidavits, and lien releases differ across registries.

5. Clear the Massachusetts estate tax lien before listing the property for sale. This is not optional and cannot be done at the closing table. The lien release or affidavit must be recorded before the purchase and sale agreement goes binding, or at minimum, before the closing date — and processing times at the DOR and Registry of Deeds create lead time that must be planned for.

Multi-state estates take longer, cost more, and require more coordination than single-state estates. The administrative burden on the Personal Representative is significantly higher. If you're managing a Massachusetts primary probate that includes out-of-state real estate, or an ancillary Massachusetts probate for a non-resident estate, the Massachusetts Probate Process Guide covers the Massachusetts-specific procedural requirements in detail, including the estate tax lien clearance process and the forms required to transfer Massachusetts real estate under probate court authority.
