My mother was not married at the time (of writer's birth) When I went to get a copy of my birth certificate just a few years ago, there was nothing at all on file. I asked my mother about this and she told me that, since it was such an "improper" situation, the doctor didn't file a birth certificate when I was born. When she got married three years later, he filled out a form that I used all my life. It listed her husband as my father. It was not a birth certificate, but it was accepted by everyone who needed to see one.
