How to Legally Change a Name in Delaware

Step 1 – Complete the Petition for Name Change

Eligible adults who want to change their legal name must fill out the Petition for Name Change. The form packet includes the Affidavit of Petitioner, which must be completed and notarized by a notary public.

Step 2 – Notarize Affidavit of Petitioner

The Petition for Name Change and the Affidavit of Petitioner must be presented to a notary public by the petitioner for notarization. Photo ID will be required.

Step 3 – File with the Court of Common Pleas

The Petition for Name Change and Affidavit must then be filed with the Court of Common Pleas in the petitioner’s jurisdiction.[1]

The following must also be provided:

  • Birth Certificate
  • Photo ID
  • Documents related to any previous name change
  • Order of Divorce or other court document related to this name change
  • Filing fee

After the filing is completed, the court will give the petitioner a court hearing date.

Step 4 – Go to Court Hearing

The petitioner must arrive 30 minutes early for their hearing to check in with the bailiff and be directed to the appropriate courtroom (proper dress is required). If the name change is approved, the judge will sign an order to be used as proof of the change.[2]

Marriage and Divorce

Delaware residents can update their name during the divorce or marriage process by having the name change included in their divorce decree or marriage license. If the name change wasn’t included in the marriage/divorce, a Petition for Name Change must be filed along with a certified copy of the divorce decree or marriage license to request the change.
