When someone dies without a will in Delaware, their assets may pass through probate or sometimes through a simpler process using an heirship affidavit. This document helps prove who the legal heirs are, so property like real estate can be transferred without going through full court proceedings. But getting it wrong can delay things, cost money, or even block access to inherited property.

What is an heirship affidavit and when do you need one?

An heirship affidavit is a sworn statement that identifies the deceased person’s living relatives and proves they are legally entitled to inherit. It’s used most often when someone owns land or a house and there's no will. The state recognizes this document as proof of ownership for transferring deeds.

You might need one if a family member passed away, left a house behind, and never updated the title. Or if a relative died and the surviving family wants to sell or refinance the home but can’t because the name on the deed isn’t updated.

Common mistakes people make when filing an heirship affidavit

Even small errors can cause delays or rejection. Here are the most frequent problems:

Missing or incorrect information about the deceased

Some people skip details like the full legal name, date of death, or place of death. Others use nicknames instead of official names. That creates confusion. The affidavit must match public records exactly like the death certificate.

If the date of death is off by even one day, the document could be rejected. Always double-check this against the official death certificate.

Wrong list of heirs or incomplete family tree

It’s common to leave out distant cousins or forget that a child from a prior marriage also has rights. In Delaware, heirs include spouses, children, parents, and siblings but only if they’re alive and not legally disinherited.

For example, if a man had two children with his first wife and married again, both sets of children are eligible unless a will says otherwise. Omitting one group can invalidate the whole affidavit.

Not having enough signatures or improper notarization

The affidavit must be signed by at least two disinterested witnesses people who aren’t named as heirs. These witnesses must swear they know the facts stated in the document. They also need to sign in front of a notary.

A common mistake? Using a relative as a witness. Even if the relative is trustworthy, Delaware law requires witnesses to have no financial interest in the estate. If you’re unsure, check this guide on legal pitfalls.

Using outdated or incorrect forms

Delaware doesn’t publish a single standard form. Different counties may have slightly different versions. Some clerks accept self-made affidavits, but others require specific language.

Always confirm with your local county recorder’s office before filling anything out. A form missing a required clause like a statement about whether the deceased had a will might not be accepted.

Not filing with the right office

After completing the affidavit, it must be filed with the county where the property is located. Filing it in the wrong county can cause delays or force you to start over.

For instance, if a house is in New Castle County, the affidavit must go to the New Castle County Recorder’s Office not the one in Kent County. You can find the correct address and procedure through your local government website.

Ignoring the need for multiple copies

Most offices want at least three copies: one for the clerk, one for the new owner, and one for your records. Missing this step means you’ll need to refile later.

Also, keep a copy of the original signed affidavit and all supporting documents like death certificates and birth certificates for your files.

How to avoid these mistakes

Take your time. Review every section. Ask yourself: “Does this match what’s on the death certificate?” “Are all heirs listed?” “Do I have two non-family witnesses?”

Before signing, walk through the entire affidavit with a trusted friend or a lawyer familiar with Delaware probate rules. Even a quick review can catch issues early.

What to do next

Start by gathering key documents: the death certificate, birth certificates of heirs, marriage certificates (if applicable), and any existing deeds. Then, contact your local county recorder’s office to confirm the exact requirements.

Once everything is ready, complete the affidavit carefully. Have two witnesses sign in front of a notary. File the original and copies with the correct office.

If you're unsure about any part, don’t guess. Contact the county clerk directly or consult a local attorney. Getting it right the first time saves time and stress.

  • Check the full name and date of death against the death certificate
  • List every living heir children, spouse, parents, siblings
  • Use two witnesses who aren’t related and have no stake in the inheritance
  • Have all signatures notarized properly
  • Use the correct form for your county
  • File with the recorder’s office in the correct county
  • Keep copies of everything for your records
