Maryland Ancillary Probate

An out-of-state owner who leaves Maryland real property needs ancillary probate through the Register of Wills. See the foreign personal representative process.

By Settled Editorial

When someone who lived in another state dies owning real estate in Maryland, that Maryland property can need its own Maryland step, even though the main estate runs in the home state. Maryland handles this through its foreign personal representative process under the Estates and Trusts Article, Title 5, Subtitle 5. The home-state representative files authenticated documents with the Register of Wills in the Maryland county where the property sits, and can then deal with the land.

This runs in two directions for Maryland families. A Maryland resident who owned land in another state faces that other state's process. An out-of-state resident who owned Maryland real estate faces the Maryland step, and that is the case this page walks through. Below you will find when a Maryland proceeding is needed, how the foreign personal representative path works, the small-estate route, the Maryland taxes that still apply, and how planning avoids the whole thing. If you are still opening the main estate, start with the Maryland probate guide.

What Is Ancillary Probate?

Ancillary probate is a second proceeding in a state where the deceased owned property but did not live. The main proceeding, in the state where the person lived, is called domiciliary probate. The second one exists because real estate is governed by the law of the state where the land sits, not the state where the owner lived. A court in one state cannot pass title to land in another. To clear title to Maryland real estate, the Maryland record has to be opened, even when the main estate is handled somewhere else.

A Maryland ancillary matter usually reaches:

  • Real estate physically located in Maryland
  • Leasehold property in Maryland
  • Tangible personal property kept in the state

It does not reach property in the home state, property in a third state, or anything that already passes outside probate, such as trust assets, survivorship property, or an account with a payable-on-death beneficiary.

When a Maryland Proceeding Is Needed

Two situations come up, and Maryland families run into both.

A Maryland Resident Who Owned Out-of-State Property

If a Maryland resident dies owning a vacation home, farm, or mineral interest in another state, the Maryland estate handles the Maryland assets, and the other state's court handles the property there. That ancillary proceeding, with its own rules and costs, belongs to the other state. This guide cannot map every state's procedure, so confirm the requirements with an attorney licensed where the property sits.

An Out-of-State Resident Who Owned Maryland Property

If someone who lived in another state owned Maryland real estate at death, the estate is administered first in the home state, and a Maryland step then reaches the Maryland land. This is the case a Maryland guide can address directly, and the rest of this page focuses on it.

Two Maryland structure points matter before you file. First, Maryland probate runs through two offices in each of its 24 jurisdictions: the elected Register of Wills, which opens the estate, files the will, keeps the records, and collects the fees, and the Orphans' Court, a three-judge probate court that supervises administration and hears disputes. Maryland is not a single circuit-court-clerk state. In Montgomery, Harford, and Howard counties there is no separately elected Orphans' Court, so the circuit court judges sit as the Orphans' Court instead.

Second, watch the Baltimore names. Baltimore City is an independent city, separate from Baltimore County. Each has its own Register of Wills and its own Orphans' Court, so property in the city and property in the county go to different offices. Confirm which jurisdiction the land is in before you send anything.

The Maryland Foreign Personal Representative Process

Maryland does not always require a full second estate. Subtitle 5 lets the home-state representative, called a foreign personal representative, act on Maryland property after filing with the Register of Wills. A foreign personal representative is not required to take out Maryland letters. (Source: Md. Code, Estates and Trusts §5-501, mgaleg.maryland.gov.) Once qualified in the home state, that representative may exercise in Maryland the powers of the office, may sue and be sued here, and holds the same authority over Maryland real property as a Maryland-appointed representative. (Source: Md. Code, Estates and Trusts §5-502, mgaleg.maryland.gov.)

Step 1: Confirm the Home-State Estate and Gather Authenticated Documents

The Maryland step builds on the home-state proceeding, so that estate usually needs to be open first. From the home-state court, obtain a copy of the appointment as personal representative and the will, if there is one, each authenticated under the federal full-faith-and-credit statute, 28 U.S.C. §1738. "Authenticated" means copies that carry the issuing court's certification, not plain photocopies.

Step 2: File With the Register of Wills Where the Property Sits

A foreign personal representative administering Maryland property files with the register of the county where the largest part in value of the Maryland property is located. The filing includes the authenticated copy of the appointment, the authenticated will, and a verified application that describes all of the decedent's Maryland property and sets forth its market value and how that value was determined. The register then determines the Maryland inheritance tax due, and can require added proof of value or run an independent review. (Source: Md. Code, Estates and Trusts §5-504, mgaleg.maryland.gov.) If the property sits in more than one Maryland county, ask each register how it wants the record handled. Use the Maryland Register of Wills directory to find the right office.

Step 3: Notify Creditors

A foreign personal representative dealing with Maryland property publishes notice to creditors once a week for three successive weeks, and the register enters the estate in a "Claims Against Nonresident Decedents" docket, where an unpaid claim can stand as a lien against the Maryland real and leasehold property for up to 12 years. (Source: Md. Code, Estates and Trusts §5-503, mgaleg.maryland.gov.) The broader Maryland claim deadlines are covered in the Maryland creditor claims guide.

Step 4: Pay the Inheritance Tax and Clear Title

Once the tax is paid or secured, the register issues the foreign personal representative a receipt, and no full ancillary administration is required for those assets, because a foreign personal representative is not required to take out letters in Maryland (§5-501). Until the inheritance tax is paid or secured, the unpaid amount stays a lien on the property. (Source: Md. Code, Estates and Trusts §5-501, mgaleg.maryland.gov; the lien rule is §5-505, mgaleg.maryland.gov.) With the receipt in hand, the representative can transfer the Maryland land to the people entitled to it. If a foreign personal representative fails within a reasonable time to transfer title, the Orphans' Court can order the transfer directly. (Source: Md. Code, Estates and Trusts §5-506, mgaleg.maryland.gov.)

Small-Estate and Simpler Paths

A full track is not always required. Maryland administers an estate as a small estate when the property subject to administration in Maryland is $50,000 or less as of the date of death. That ceiling rises to $100,000 when the surviving spouse is the sole legatee or heir. (Source: Md. Code, Estates and Trusts §5-601, mgaleg.maryland.gov.) A small estate still opens with the Register of Wills, but the paperwork and the wait are shorter. When a nonresident's only Maryland asset is a modest one, ask the register whether the small-estate route fits before you plan a longer proceeding.

Maryland Taxes on the Property

Maryland is the one state that levies both a state inheritance tax and a state estate tax, and the Maryland real property owned by a nonresident stays within reach of both.

Inheritance tax. Maryland charges a 10% inheritance tax on the clear value of property that passes to certain takers. (Source: Md. Code, Tax-General §7-204, mgaleg.maryland.gov.) Close family is exempt: property passing to a spouse, a child or other lineal descendant, a parent, a grandparent, or a brother or sister owes no inheritance tax. (Source: Md. Code, Tax-General §7-203, mgaleg.maryland.gov.) So a Maryland house left to a child passes free of the tax, while the same house left to a niece, a nephew, or a friend carries the 10% charge. This is the tax the register settles when a foreign personal representative files under §5-504.

Estate tax. Maryland also imposes a separate estate tax with a $5 million exemption that is not indexed, and a top rate of 16%. (Source: Md. Code, Tax-General §7-309, mgaleg.maryland.gov.) Only larger estates reach it, so most ancillary matters deal with the inheritance tax alone.

How to Avoid a Maryland Ancillary Proceeding

The cleaner fix is to keep the Maryland property out of probate before death. These are planning tools, not remedies after a death.

Revocable Living Trust

A revocable living trust holds property during life and passes it to named beneficiaries at death without probate in any state. One trust can hold real estate in several states, and a successor trustee has authority everywhere, which is why a trust often answers a multi-state real estate question. A trust only works for property actually retitled into it, so the deed into the trust has to be recorded.

Survivorship Title

Real estate held with a valid right of survivorship, including tenancy by the entirety between spouses, passes to the surviving owner outside probate. Read the recorded deed before you assume a transfer is automatic, because the survivorship right has to be stated in the deed.

Transfer-on-Death Deed, Starting October 1, 2026

Maryland enacted a transfer-on-death deed for real property that takes effect October 1, 2026, letting an owner name a beneficiary to receive the land at death without probate. (Source: 2026 Md. Laws Ch. 751 (House Bill 738), mgaleg.maryland.gov.) An out-of-state owner of Maryland real estate can use a recorded Maryland deed of this kind, once the law is live, to spare the family a later filing. The Maryland guide on how to avoid probate walks through each of these tools.

Cost and Timeline

The Maryland cost on the foreign personal representative path is mostly the inheritance tax the register settles, plus a modest register recording charge and any attorney fees. There is no separate per-county probate filing fee to invent here; Maryland's value-based probate fee schedule is statewide and set by statute, and the foreign-representative filing centers on the tax receipt rather than a new fee. An ancillary matter sits on top of the home-state estate, so the family pays the home-state costs plus the Maryland costs in each place.

Timeline depends on the county and on how fast the home-state estate can produce authenticated documents. A straightforward matter can move in a few months once those copies and a clear value figure are in hand, while an estate that has to sell the Maryland property or resolve disputed claims takes longer. Confirm both cost and timing with the register where the property sits. For the sequence a Maryland estate follows, see the Maryland probate timeline guide.

Practical Tips

Map the Maryland property first. Identify the county, or Baltimore City, where each parcel sits, since the filing goes to that register, and the city and the county are separate jurisdictions.

Order authenticated documents early. The Maryland step depends on authenticated copies of the appointment and the will under 28 U.S.C. §1738. Request them as soon as the home-state estate can produce them.

Pin down the value. The register determines the inheritance tax from the Maryland property's market value, so gather a defensible figure, such as an appraisal, before you file.

Check who inherits. The inheritance tax turns on the relationship of the taker. A Maryland house left to a child is exempt; the same house left to a collateral heir carries the 10% charge. The Maryland intestate succession guide explains who inherits when there is no will.

Confirm the local packet. Each Register of Wills can use its own checklists and forms. Verify the specific requirements with the office before you file. See the Maryland executor duties guide for the wider set of tasks a representative carries.

Frequently Asked Questions

What is ancillary probate in Maryland?

Ancillary probate is a second Maryland step used when someone who lived in another state owned Maryland real estate. The home-state estate handles most assets, and the Maryland step, filed with the Register of Wills where the property sits, clears title to the Maryland land through the foreign personal representative process in Estates and Trusts Title 5, Subtitle 5.

Do I have to open a full new estate in Maryland?

Often no. A personal representative already appointed in the home state can act on the Maryland property by filing authenticated documents and a verified application with the register, paying the Maryland inheritance tax, and taking a receipt, without a second full appointment. Confirm your facts with the register, since a Maryland property that has to be sold or that draws a dispute can still need more.

Where do I file for Maryland ancillary probate?

You file with the Register of Wills in the Maryland county where the largest part in value of the property is located. Baltimore City is its own jurisdiction, separate from Baltimore County, so confirm which office applies using the Maryland Register of Wills directory.

Does Maryland tax a nonresident's Maryland property?

Yes. Maryland's 10% inheritance tax reaches Maryland real property no matter where the owner lived, though a spouse, child or other lineal descendant, parent, grandparent, or sibling takes it exempt. Larger estates over the $5 million exemption can also owe Maryland estate tax.

How can I avoid Maryland ancillary probate?

Plan before death. A funded revocable living trust, valid survivorship title, or, once the new law is live on October 1, 2026, a recorded Maryland transfer-on-death deed can pass Maryland real estate outside probate, so no ancillary step is needed.
