Maryland Probate Petition Filing Guide

Losing a loved one is hard enough without navigating the legal system that follows. If you've been named as a personal representative or you're an heir trying to understand what comes next, you'll likely need to file a probate petition in Maryland. The process has specific rules, required forms, and strict deadlines and missing even one step can delay the estate for weeks or months. This guide walks you through what a Maryland probate petition actually involves, how to file one correctly, and where most people go wrong.

What is a probate petition, and when do you need to file one in Maryland?

A probate petition is the legal document that asks the Orphans' Court in the county where the deceased person lived to open a probate estate. Without this filing, no one has the legal authority to manage the deceased person's assets, pay their debts, or distribute property to heirs.

You need to file a probate petition when someone dies and leaves behind assets that require court supervision. This includes bank accounts, real estate, vehicles, investments, or personal property held solely in the deceased person's name. In Maryland, probate is handled by the Register of Wills in each county, not a general circuit court.

If you're unsure whether probate is necessary, the key question is whether the deceased owned assets that don't automatically transfer by law such as through joint ownership, beneficiary designations, or a living trust. You can learn more about how to open a probate estate in Maryland if you need help making that determination.

Who can file a probate petition in Maryland?

Maryland law sets a clear order of priority for who may file:

A person named as personal representative (executor) in the will
A surviving spouse or heir if no will exists
A creditor of the estate, under certain conditions

If you were named in the will as executor, you have first priority. But being named doesn't automatically mean you have to serve you can decline. If no one named in the will is willing or able to serve, the court can appoint someone else. Maryland's probate petition requirements for executors outline what's expected of you before and after filing.

Which Maryland court handles probate petitions?

Probate petitions in Maryland are filed with the Register of Wills in the county where the deceased person was a legal resident at the time of death. Each county has its own Register of Wills office, and they operate under the supervision of the local Orphans' Court.

For example, if the deceased lived in Montgomery County, you'd file with the Montgomery County Register of Wills. If they lived in Baltimore City, you'd file with the Baltimore City Register of Wills. Filing in the wrong county will get your petition rejected.

The Orphans' Court itself handles contested matters, hearings, and approvals of certain estate actions. If you need help understanding the forms used at this level, this guide to Orphans' Court petition forms covers the documents you're most likely to encounter.

What forms do you need to file a Maryland probate petition?

The specific forms depend on whether the deceased left a valid will. Here's what you'll typically need:

When there is a will (testate estate)

Petition for Probate (Register of Wills form) this requests that the court accept the will and appoint the personal representative
The original will a photocopy won't do; the court requires the original document
Death certificate a certified copy
Fiduciary bond (if required) some wills waive this, but the court may still require one

When there is no will (intestate estate)

Petition for Administration similar to the probate petition, but for estates without a will
Death certificate
Fiduciary bond more commonly required when there's no will

You can find a detailed breakdown of each form and what goes on them in our filing petition forms walkthrough. Getting the forms right the first time saves you from return trips to the Register of Wills office.

How do you actually file the probate petition step by step?

Here's the process as it typically plays out:

Gather the documents. Collect the original will, certified death certificate, and any information about the deceased's assets and debts.
Complete the petition form. Fill out the appropriate petition from the Register of Wills. You'll need details like the deceased's full legal name, date of death, county of residence, names and addresses of heirs, and an estimated value of the estate.
File the petition. Bring or mail the completed petition, the original will, and the death certificate to the Register of Wills in the correct county. There's a filing fee, which varies by county but is generally based on the estate's value.
Take the oath. The personal representative must swear an oath of office before the Register of Wills or a designee.
Receive Letters of Administration or Letters Testamentary. Once approved, the court issues these documents, which give the personal representative legal authority to act on behalf of the estate.

What information goes on the probate petition form?

The petition form asks for specific details. Having this information ready before you start filling it out will make the process smoother:

Full legal name of the deceased (as it appears on legal documents)
Date and county of death
Whether the deceased left a will, and if so, where it was found
Names, addresses, and relationships of the surviving spouse, children, and other heirs
Estimated value of the estate (real property, personal property, bank accounts, etc.)
Your name, address, and relationship to the deceased
Whether you're requesting a fiduciary bond

One detail people frequently get wrong: the estimated estate value. Maryland uses this figure to determine filing fees and, in some cases, whether the estate qualifies for simplified procedures. You don't need an exact number at this stage, but your estimate should be reasonable. If you significantly undervalue the estate, expect the court to ask questions later.

How much does it cost to file a probate petition in Maryland?

Filing fees vary by county and are generally calculated based on the gross value of the estate. As a rough range, fees can be as low as a few hundred dollars for small estates to over a thousand for larger ones. Some counties also charge additional fees for certified copies of Letters Testamentary or Letters of Administration.

Beyond filing fees, you should budget for:

Certified copies of the death certificate (you'll likely need several)
Cost of publishing a notice to creditors (required in many cases)
Potential legal fees if you hire a probate attorney

Check with your local Register of Wills office for their current fee schedule, as these amounts are set at the county level.

What are common mistakes people make when filing?

After helping many Maryland residents navigate this process, here are the mistakes that come up most often:

Filing in the wrong county. The petition must go to the county where the deceased resided, not where they died or where the property is located.
Submitting a copy instead of the original will. The Register of Wills needs the original. If you can't find it, you'll need to address that with the court before proceeding.
Leaving out required heirs. Maryland law requires you to list all known heirs, even if you believe they won't contest the estate. Omitting someone can create legal problems down the road.
Underestimating estate value. This triggers problems with fees, tax filings, and court scrutiny.
Not understanding fiduciary duties. Once appointed, the personal representative has a legal obligation to act in the estate's best interest. That means keeping detailed records, paying valid debts before distributing assets, and filing required accountings with the court.
Waiting too long. Maryland doesn't have a strict deadline for opening probate, but delays create complications assets can lose value, creditors may file claims, and heirs may take action.

What happens after the petition is approved?

Once the Register of Wills issues Letters Testamentary or Letters of Administration, the personal representative can begin managing the estate. This includes:

Opening an estate bank account to handle all financial transactions
Inventorying assets and filing an inventory with the Register of Wills (typically due within 90 days of appointment)
Notifying creditors by publishing a notice in a local newspaper
Paying valid debts and taxes from estate funds
Filing a final accounting with the court showing all income, expenses, and proposed distributions
Distributing remaining assets to heirs after court approval

Each of these steps has its own timeline and requirements. Missing a deadline for the inventory or accounting can result in the court removing the personal representative.

Quick checklist before you file

Use this as a final review before heading to the Register of Wills:

✅ You've identified the correct county for filing
✅ You have the original will (if one exists)
✅ You have a certified death certificate
✅ You've completed the correct petition form (probate or administration)
✅ You've listed all known heirs with their addresses and relationships
✅ You have a reasonable estimate of the estate's gross value
✅ You're prepared to take the oath of office as personal representative
✅ You know the filing fee amount and have payment ready
✅ You understand that once appointed, you're legally responsible for managing the estate properly

Next step: Call or visit your county's Register of Wills office before you file. Most offices are willing to answer procedural questions and can confirm which forms you need for your specific situation. A 15-minute conversation before you file can prevent weeks of delays afterward.
