[Please read the first post before posting an answer.] Assalam Alaykoum, I will convert to Islam soon and thus need to think about changing my western first name, middle name and surname (also called “family name” or “last name”). I just read this article: https://islamqa.info/en/7180 At the very bottom of the article it is written: My non-Muslim father married a non-Muslim women, lived with her for 15 years, had 3 children with her, then they separated and never saw each other again (except for one occasion perhaps). My father then met my non-Muslim mother, they lived together for 25 years, they had 1 children (me), then my father died. The problem is: My father never officially divorced with the other women, he never officially married my mother, when he died he officially was still married to the other women. Thus my question is: For my surname, should I take the surname of my father or the surname of my mother? Another idea would be to take the surname of one of my parents as my surname, and take the surname of my other parent as my middle name. I have four options: 1) My surname = surname of my father ; My middle name = nothing 2) My surname = surname of my mother ; My middle name = nothing 3) My surname = surname of my father ; My middle name = surname of my mother 4) My surname = surname of my mother ; My middle name = surname of my father I personally have no preference.
