I always train according to TILA - reasoning that if we're sued, it will be under TILA, not Reg Z. If the son lives there, and is signing the note - I'd recommend giving him the ROR.
I'm assuming that you are willing to release the husband from the loan? Too often, customers (and bankers!) think that because they quit claimed the property, or the divorce settlement says so - that they no longer have any obligation under our note. Not true!!
