What is the name of your state? CA We bought a new home for our son 7 years ago and put $40,000 down and he moved in. He has taken very good care of the home and married about 4 years ago. He has been responsible for everything on the house. He is now going to get a new loan and wants to add his lovely wife to the deed. Since the house has gone up almost $500,000. I have some concerns. I want to make sure that when we add her, that it now becomes 2/3 my husband and myself and son and his wife 1/3 with all of us as joint tenants (not 25% each). Will that work and how do we handle it. Our plan is that when we are dead, its his but should he get divorced in a few years....One 1/2 of his third is plenty I think. Since they have been married, they took out an equity loan of $50,000.....to pay some bills....so don't think we are stingy.
