If you’re handling an estate in Delaware and need to file for letters testamentary, knowing the exact filing fees and what they cover isn’t just helpful, it’s necessary. You’ll need this information before submitting paperwork to the Register of Wills, especially if you’re acting as executor and want to avoid delays or rejected filings due to incorrect or incomplete payment.

What are letters testamentary in Delaware?

Letters testamentary are official court documents that give an executor legal authority to manage and distribute a deceased person’s estate when there’s a valid will. In Delaware, these are issued by the Register of Wills after a probate petition is filed and approved. They’re not automatic you must apply, provide required documents (like the original will and death certificate), and pay the correct fee.

How much does it cost to file for letters testamentary in Delaware?

As of 2024, the base filing fee for letters testamentary in Delaware is $25. This is a flat fee charged by the Register of Wills for processing the application. It does not include other potential costs like certified copies, postage, or attorney assistance if needed.

You can find more details about current filing fees and accepted payment methods in our explanation of Delaware probate document fees.

What else might cost money during this process?

While the $25 filing fee is the only mandatory cost for the letters themselves, people often overlook related expenses:

• Certified copies: $5 each (useful for banks, brokers, or real estate transfers)
• Mail or courier fees: If you’re mailing documents instead of filing in person at a Register of Wills office
• Legal help: Not required, but some executors hire an attorney for complex estates fees vary widely
• Publication notice: Required in some counties if heirs are unknown or hard to locate (not a Register of Wills fee, but a separate cost)

Common mistakes people make with letters testamentary filing fees

One frequent error is assuming the $25 fee covers everything. It doesn’t. Some filers show up with only $25, then realize they need three certified copies ($15 extra) or that their check was made out to the wrong office name. Others try to pay with cash at offices that only accept checks or money orders.

Another mistake: using outdated fee information. Fees rarely change, but they do so always verify on the official Delaware Register of Wills website before filing.

Where do you pay and how?

Fees are paid directly to the Register of Wills office in the county where the deceased lived at the time of death. Offices accept checks or money orders made payable to “Register of Wills” (plus the county name, e.g., “Register of Wills – New Castle County”). Cash is not accepted at most locations.

Some counties offer online filing options, but payment still requires a valid check or money order mailed separately unless otherwise specified. For clarity on accepted formats and timing, refer to our breakdown of how much it costs to file letters testamentary in Delaware.

Do you always need letters testamentary?

No. If the estate is small under $30,000 in personal property and no real estate you may qualify for a simplified procedure called “small estate affidavit,” which has no filing fee. But if the estate includes real property, stocks, or bank accounts requiring formal transfer, letters testamentary are usually required.

Next step: Before you file

Double-check these four things:

1. You have the original signed will (or a certified copy if the original is lost)
2. You’ve completed the correct Register of Wills petition form for your county
3. You’re bringing or mailing a check or money order for $25, payable to “Register of Wills” + county name
4. You’ve printed and brought two extra copies of all documents (for your records and possible clerk review)
