My niece and her then partner had baby boy, child has fathers surname.
They are no longer together (he is a waste of space).
so for the last few years she has her surname child has fathers surname.
She is due to marry shortly and child with still have fathers surname.
I really don't see the point of unmarried couple giving children the fathers surname.
If a mother has let's say 2 children by 2 different fathers then the children have different surnames...... It's wrong in my opinion. If they aren't married then give the child the mothers surname.
