text: last name issue? would it be wrong to change my last name to my daughter's (her sperm donor's) last name? could my husband and i do it legally without any repercussions? her sperm donor does not have any contact (of his own free will) but he won't give up his rights. which i don't understand, but that's another story. my husband is willing to do it, as he has no ties to his current last name. do you think it is possible? go for it. if that would make u feel more like a family. i dont see anything wrong.
