Hello everyone, I've been in a similar situation... My husband works in the organs and we haven't scheduled anything yet, he can't right now because of work. We plan to do it in a year or two. If we give our baby a surname and patronymic that isn't from his marriage, will there be any problems with him not being married? And will I still be considered a single mother? Or is that already gone?
