If you’re asking how much does it cost to file letters testamentary in Delaware, you’re likely handling an estate after someone has passed and you need legal authority to act on behalf of that estate. Letters testamentary are the court-issued documents that officially name you as executor (or personal representative) and let you manage assets like bank accounts, real estate, or investments. Knowing the exact filing cost matters because it’s your first concrete step in probate and unexpected fees can delay things or strain an already tight budget.

What is the filing fee for letters testamentary in Delaware?

As of 2024, the standard filing fee to submit a petition for letters testamentary in Delaware’s Register of Wills office is $25. This fee applies whether you're filing in New Castle, Kent, or Sussex County. It’s a flat fee no sliding scale based on estate size and it’s paid when you submit your petition, not later in the process.

Are there other mandatory costs besides the $25 filing fee?

Yes but only if certain conditions apply. For example:

  • If the will hasn’t been witnessed or self-proved under Delaware law, you may need to file affidavits from witnesses. There’s no fee for filing those, but getting them signed and notarized could involve small notary fees ($5–$15).
  • If the estate includes real property, you’ll likely need certified copies of letters testamentary later each copy costs $5 through the Register of Wills.
  • There’s no separate “probate court” fee in Delaware for letters testamentary the Register of Wills handles this entirely, and the $25 covers the core filing.

You won’t pay attorney fees, appraisal fees, or bond premiums just to file for letters testamentary those come later (and only if needed). A full breakdown of what each fee covers is available in our filing fees cost breakdown.

When do you actually need to file for letters testamentary?

You need letters testamentary if the deceased owned assets solely in their name with no designated beneficiary or joint owner like a house titled only in their name, or a bank account without a payable-on-death (POD) designation. If all assets pass automatically (e.g., via joint tenancy, beneficiary designations, or a living trust), probate and therefore letters testamentary may not be necessary at all.

For example: Maria died leaving a Delaware condo in her name alone and a $40,000 savings account with no POD. Her daughter must file for letters testamentary to sell the condo and close the account. But if that same account had named her daughter as beneficiary, the $40,000 would transfer directly no filing required.

Common mistakes people make when calculating the cost

One frequent error is confusing the $25 filing fee with other estate-related charges like the Delaware inheritance tax (which doesn’t apply to spouses, parents, children, or siblings, and is calculated separately) or optional services like expedited processing (not offered for letters testamentary in Delaware). Another mistake is assuming postage, certified mail, or document preparation services are mandatory they’re not. You can file in person, by mail, or via the Register of Wills’ online portal (where available), and prepare forms yourself using free templates from the Delaware estate paperwork guide.

Where do you pay the $25 fee and how?

You pay it directly to the Register of Wills office in the county where the deceased lived at the time of death. Payment methods vary slightly by county: New Castle accepts cash, check, or money order; Kent and Sussex accept checks or money orders only (no cash). Credit cards aren’t accepted for this filing. You’ll also need to bring two copies of your completed petition and any supporting documents details on required forms are explained in our probate document fees explanation.

What’s next after paying the $25 fee?

After payment, the Register of Wills reviews your petition usually within 3–5 business days if everything is complete and accurate. If approved, you’ll receive your letters testamentary (often as a stamped, certified document). From there, you can begin gathering assets, paying debts, and distributing what remains always following Delaware’s probate timelines and reporting requirements.

Before filing, double-check that the will is original (not a copy), that all names and addresses match official records, and that you’ve listed all known heirs even distant ones as required by law. A helpful summary of all related expenses including optional but common out-of-pocket costs is in our expense summary.

Next step: Gather the original will, a certified copy of the death certificate, and the $25 filing fee. Then go to the Register of Wills office in the correct county or mail your petition with a self-addressed stamped envelope.
