Making changes to birth certificates

The state of Washington Center for Health Statistics has adopted a birth correction policy. The changes took effect January 15, 2015. Every birth certificate ordered from the King County Vital Statistics Office will have a copy of the new policy along with updated forms to fill out for corrections. As of January 15, 2015 the state of Washington is requiring both parents signatures on the Affidavit of Correction to process corrections for names on a birth certificate. Our office will continue to send the new policy for the next few months to ensure that our customers have the correct form for processing birth corrections. The Affidavit of Correction must be returned within one year of the issue date to receive a replacement copy for free. If after the year, the fee for a birth certificate is $25.00.

Download the Affidavit of Correction and the policy (PDF). Print out the form and follow the instructions for completing the form.

If you have any questions about processing the Affidavit of Correction, contact the Washington State Center for Health Statistics at 360-236-4300, toll free 1-800-525-0127 for Washington state residents only or King County Vital Statistics Office at 206-897-4551.

Sex designation change on a birth certificate

"X" means a gender that is not exclusively male or female, including, but not limited to, intersex, agender, amalgagender, androgynous, bigender, demigender, female-to-male, genderfluid, genderqueer, male-to-female, neutrois, nonbinary, pangender, third sex, transgender, transsexual, Two Spirit, and unspecified.
