If you were born in Connecticut, you can get a new birth certificate showing female, male, or non-binary by mailing DPH your own notarized affidavit and a notarized affidavit from a licensed doctor, PA, APRN, or psychologist. No surgery or court order is required, and there is no amendment fee.

How it works

Since 2015 (Public Act 15-132), Connecticut issues a replacement birth certificate to reflect a gender change. The provider affidavit states that you have had "surgical, hormonal, or other treatment clinically appropriate" for your gender transition; the provider decides what is appropriate for you, and surgery is not required. The new certificate replaces the old one, is not marked "amended", and the original is sealed.

You can change your name in the same request by including a certified court order. A later change to the sex on the certificate requires a court order.

This only works if you were born in Connecticut. If you were born in another state, contact that state's vital records office; if that state requires a court order, Connecticut Probate Courts can issue an order confirming a gender change for residents born elsewhere.

Steps

  1. Get the provider affidavit signed and notarized[3][1]

    Ask your doctor, PA, APRN, or psychologist to complete the Affidavit of Health Care Practitioner and sign it before a notary. Many clinics (including Planned Parenthood of Southern New England and Anchor Health) write these letters for patients.

  2. Sign your own affidavit before a notary[3]

    Complete the Affidavit of Applicant, choosing Female, Male, or Non-Binary. If you also want your new legal name on the certificate, check the box and include a certified copy of your court order.

  3. Mail everything to DPH Vital Records[3][2]

    Send both affidavits, a photocopy of your photo ID, any court order, and (optional) the certified copy request with a $30 money order payable to "Treasurer, State of Connecticut" to:

    Connecticut Department of Public Health, Office of Vital Records, Record Replacement Unit, 410 Capitol Avenue, MS #11VRS, Hartford, CT 06134.

    Credit cards and personal checks are not accepted. Questions: 860-509-7956.

    Cost
    Free amending the sex designation; $30 certified copy of the new birth certificate from DPH (each)

  4. Changing only your name? Go to the town of birth[4]

    Optional

    If you are not changing the sex marker, send the town clerk (registrar of vital statistics) in the town where you were born an original certified name change order, the notarized "My Name Change Affidavit," and a photo ID, in person or by mail.

Use the new certificate to update records that follow your birth certificate (school, some employers, passport renewal when federal policy allows). Your Connecticut license can be changed separately by self-attestation (form B-385). Federal passport and Social Security sex markers cannot currently be changed; names can.

Tips3 tips from people who have done this
  • Print the forms on plain white paper; DPH asks for it.
  • Order at least one certified copy with your packet so you do not need a second request later.
  • Think carefully before choosing; a second change to the sex on the certificate requires a court order.
