Since you're in louisiana, i thought i could help. couple of questions, when you say "mortgage", what exactly do you mean. in louisiana, a mortgage is only a security interest in immovable property, if he signed it, then that meant he *was* part owner at that time and granted the bank/lender that mortgage. there is no real disadvantage to having him on that that i can think of, in fact, it's probably be problems if he wasn't and he was your husband at the time. even if you are thinking about the promissory note, that would make the signers liable on the note, it doesn't really give either one of you rights in the property. if you're talking about that he is on the title, then that depends on whether it was community property or separate, if y'all did a partition, and other issues.
