My son has got the finance for a home for me, we now want my name on the title so the house is in my name as-well. He has just separated and wants my name on and his wife's off. She wishes for this as well.

Have you closed on the home? If not, at the closing, you indicate who will be on the title. However, the lender may have something to say about that.

If you have already closed on the home and you want to change ownership, the lender has to approve the change in a case like this.

So, either way, you need to contact the lender.

Yes, whose name is on the loan? If the wife's name is on the loan, the son may have to refi without her on it.
