DH other house

[moostermum]

My DH has another house which he had when we met. I moved in and then we bought another house with my deposit and kept his house to rent out.
The old house is in his name only and his BTL mortgage.
We want to add my name to it but do we need to change the mortgage name or the deeds?

Thanks

Both
Normally the title and the mortgage need to be in the same names

You can have an interest in the equity but not the debt. This may mean postponing the transfer of legal title to a future re-mortgage or the full repayment of the existing debt. What are you trying to achieve though - an equity share or joint and several responsibility for the debt?
