How can I change my daughters' birth certificates to reflect their biological father?

Full question:

I put the wrong father on the birth certificates of both of my daughters. they are now 13 and 15 and would like to legally have their biological fathers name, whom I've been married to for 6 years. We did conduct an independent DNA test for both children. My ex husband who is not the biological father but is on the birth certificate has not been involved for the past 12 years and will not object. I am unsure of his whereabouts but he was served with a copy of the DNA test results 12 years ago and is aware of the fact that he is not the father. Where do i start to not only change the girls' names but also the birth certificates?

Answer:

In California, you can change the names on your daughters' birth certificates by following specific procedures. First, you'll need to file an affidavit stating why the changes are necessary. This affidavit must be supported by another credible person who knows the facts. You can file this with the state or local registrar (Cal. Health & Safety Code § 103225).

It's important to note that changes to a birth certificate can only be made if there is no conflicting information about parentage on the original certificate (Cal. Health & Safety Code § 103230). If your amendment is accepted, the State Registrar will send copies of the amended record to the local registrar and county recorder (Cal. Health & Safety Code § 103245).

Once the amendment is processed, you will receive a certified copy of the newly amended birth record without any additional charge, unless the amendment is filed within one year of the event (Cal. Health & Safety Code § 103250).

Due to the complexity of this process, it may be beneficial to consult with a local attorney who can advise you based on your specific situation. You may also be able to change your daughters' names to match their biological father's name at the same time.
