Delaware Probate Petition: Where to File in Person

After someone passes away in Delaware, the person handling their estate eventually needs to file probate petition forms with the right court. Knowing exactly where to walk in and hand over those documents matters more than most people realize. Show up at the wrong location, and you waste a trip and when you're already dealing with grief and paperwork, that's the last thing you need. This article breaks down the specific offices where you can submit Delaware probate petition forms in person so you can get it done right the first time.

Where exactly do you submit Delaware probate petition forms in person?

In Delaware, probate petition forms are filed in person at the Register of Wills office in the county where the deceased person lived at the time of their death. Delaware has three counties, and each one has its own Register of Wills:

New Castle County Register of Wills located in the New Castle County Courthouse, 500 North King Street, Suite 1300, Wilmington, DE 19801
Kent County Register of Wills located in the Kent County Courthouse, 38 The Green, Dover, DE 19901
Sussex County Register of Wills located in the Sussex County Courthouse, 1 The Circle, Suite 2, Georgetown, DE 19947

Delaware does not use a single statewide probate court. The Register of Wills in each county handles the probate process, including accepting petition forms, issuing letters of administration or letters testamentary, and overseeing estate administration. If you're unsure which county applies, the determining factor is the decedent's domicile their legal residence at the time of death, not necessarily where they died.

What forms do you bring when filing in person?

Before heading to the Register of Wills, gather the documents you'll need. The specific forms depend on whether the person left a will (testate) or died without one (intestate). Common forms include:

Petition for Probate of Will and Grant of Letters Testamentary (if there is a will)
Petition for Grant of Letters of Administration (if there is no will)
The original last will and testament, if one exists
A certified copy of the death certificate
A list of the decedent's known assets and debts

You can find detailed filing requirements for executors in our guide to Delaware probate court filing requirements, which covers exactly what each county expects.

When should you file the probate petition?

Delaware law requires that a will be presented to the Register of Wills within a reasonable time after death. There's no strict statutory deadline like you might find in other states, but waiting too long can create legal complications particularly if creditors need to be notified or if heirs disagree about the estate.

In practice, most attorneys and experienced executors recommend filing within 30 days of the date of death. The sooner you file, the sooner you can legally manage the decedent's bank accounts, property, and obligations.

Do all three county offices handle probate the same way?

The basic process is similar across New Castle, Kent, and Sussex counties because all three follow Delaware's probate code. However, there are practical differences worth knowing:

Office hours vary. Some offices accept walk-in filings only during certain hours. New Castle County, being the busiest, may have longer wait times than Kent or Sussex.
Filing fees differ slightly. Check with the specific county office for current fees, as they can change.
Scheduling. Some offices prefer or require you to call ahead and make an appointment before submitting your petition. Others accept walk-ins.

It's worth calling the relevant Register of Wills office before your visit to confirm hours, fees, and whether an appointment is needed. This small step can save you from showing up and being turned away.

Can someone else file the petition on your behalf?

Yes. If you're the named executor but can't go in person maybe you live out of state or have health issues your attorney can file the petition for you. Delaware allows the attorney representing the estate to appear and submit documents at the Register of Wills office. In some cases, the executor may need to sign certain forms ahead of time, and the attorney carries those signed documents to the courthouse.

If you're handling probate without a lawyer, you'll need to go in person or arrange for proper legal authorization. For a step-by-step look at the full filing process, see our article on how to file probate forms in Delaware.

What happens after you submit the forms?

Once you submit the petition and supporting documents at the Register of Wills office, several things happen:

Review The Register of Wills reviews the petition to make sure it's complete and properly filled out.
Oath The executor or administrator typically takes an oath of office, sometimes on the spot, sometimes scheduled for a follow-up visit.
Letters issued If everything checks out, the Register issues Letters Testamentary (with a will) or Letters of Administration (without a will). These letters give you the legal authority to act on behalf of the estate.
Notification You'll be responsible for notifying heirs, beneficiaries, and creditors as required by Delaware law.

The timeline from filing to receiving your letters can range from a few days to a couple of weeks, depending on the county and whether your paperwork needs corrections. Our overview of the Delaware Surrogate Court form submission process gives more detail on what to expect step by step.

What mistakes do people make when filing in person?

Filing probate forms sounds straightforward, but common errors trip people up regularly:

Going to the wrong county. The petition must be filed in the county of the decedent's legal residence, not where they died or where the property is located.
Bringing copies instead of originals. The Register of Wills needs the original will, not a photocopy. Without it, the court may treat the estate as if no will exists.
Missing signatures or notarization. Many probate forms require notarized signatures. Showing up with unsigned or unnotarized documents means another trip.
Forgetting the death certificate. You'll need a certified copy not a hospital document or funeral home letter.
Not bringing enough copies. Some offices want multiple copies of certain forms. Call ahead to ask how many.

Do you need to pay a filing fee?

Yes. Delaware's Register of Wills offices charge filing fees for probate petitions. The amount depends on the size of the estate and the specific county. As of recent years, fees typically start around a few hundred dollars and may increase based on the estate's value. Contact the county office directly for current fee schedules, and ask whether they accept cash, check, or credit card payment methods vary by location.

Practical checklist before you go

Confirm the correct county based on the decedent's legal residence
Call the Register of Wills office to verify hours, appointment requirements, and accepted payment methods
Bring the original will (if one exists)
Bring a certified death certificate
Bring all completed and signed petition forms, notarized where required
Bring multiple copies of each form
Bring a valid photo ID
Bring payment for the filing fee
Prepare to take the oath of office if required that day

Getting these items ready before your visit keeps the process moving and reduces the chance of delays. If you want a broader overview of each step in the estate process, start with our filing requirements guide for executors and work through the process from there.
