I recently had a child with a married woman who claimed she was separated.
Since she is still legally married to another man, my name is not on the birth certificate. Legally, am I responsible for child support since I am not the father in the eyes of the law?
While I am not licensed to practice law in your state, I can give some general guidance on this issue. The rest of my answer is based on my experience practicing law in Georgia as a licensed Georgia attorney.
Generally, a child born within a marriage is presumed to be the child of the husband. Therefore, you are correct. You are not the father of the child under the eyes of the law and are not obligated to pay child support.
However, in the event that they do get a divorce, the husband can dispute paternity and essentially have the child de-legitimized; meaning the presumption that the child is his under law is removed. At that point, assuming a paternity test proves that you are the biological father, you can he held accountable for child support.
Alternatively, if you decide you want legal recognition as the child’s father and, after a paternity test, you are proven to be the biological father, you could again be held accountable for child support.
