Remove Bio Father from My Birth Certificate

The laws in Wisconsin governing amending a birth certificate can be found here:

https://docs.legis.wisconsin.gov/sta...tatutes/69.pdf

You need to look at sections 69.11 and 69.12. Both explicitly deny the ability to add, delete or change the name/identity of a parent from the BC.

It would appear that under WI statute 882.04, an adult adoption may get you a new birth certificate with the adopter listed as daddy. Once that happens, new daddy is your BC daddy forever. Well, unless you grow tired of them and have someone else adopt you. I doubt the court will look favorably on that. Keep in mind though, the court is not required to grant the adoption. When the court hears you reason, they may find it not to be sufficient to warrant an adoption. Without knowing the case law on the subject, which is often more important than law itself, I cannot speak to your odds.
