Sign over deeds but keep paying mortgage

Is it possible to keep paying a mortgage but sign over the deeds to someone else? Or sign over half the house to someone else but keep the mortgage in one name only?

I don't need answers with comments around the foolishness of doing something like that. Just facts. Thanks.

No you cant, as the bank hold the deeds to the property as security over the mortgage.

A mortgage is defined along the lines of:
"A mortgage is the transfer of an interest in property (or the equivalent in law - a charge) to a lender as a security for a debt "
You're effectively trying to convert your mortgage into a personal loan.

Theoretically yes it's possible but you need the bank to agree to it and usually they don't. Sometimes it can happen that a husband and wife will stay joint mortgagees but the property can be transferred into one name only. I've acted before in these circumstances but it is unusual.
