My wife is a revert. She holds the surname of her mother. Her father has passed away. Is she obliged to change her surname to her fathers lineage as a revert? It was not her choice and she doesn't know what to do in this situation

Ustadh AbdulAziz al-Haqqan

Her lineage is to her father, and Allah Jalla wa ʿAlā says, the meaning of which is: call them by their fathers. So, she can change it to her father's.
