My question involves name change laws in the State of: Louisiana.
Okay here is my issue: I was married and in the marriage me and my soon to be ex-husband had two children together. We separated and lived apart and I got pregnant and had a third child for my boyfriend. Being I am still legally married my child received my ex's last name. My child just turned two in Jan of this year. We just established a legal paternity and have the paper work stating that my ex is not the father. My ex wants to keep this child with his last name even though a few months ago at my lawyer’s office he went in and signed an AOP stating that he knew he was not the father of my last child. With that paper signed and legal paternity results, my question is as followed:
Can we legally change my child’s last name to his bio dads and also on the birth certificate?
