There is nothing to stop you moving to another lender, of course,apart from the negative equity.
The situation you find yourself in with the existing lenderrefusing to remove someone is not uncommon if the remaining person does not haveenough income to support the mortgage or of there has been a history of arrears.
The document you need is a deed of trust where she still owns halfof the property and you on the other half, but she owns her half, holding it ontrust for you.
In the deed you would covenant to make all the mortgage paymentsand pay the bills and insure the property et cetera and in consideration ofthat, she would covenant to make no claim on the property at any stage in thefuture.
A solicitor will draft the deed for you..about £200 plus vat. Ideally it should be registered at HM Land Registry
There is no document that she can sign whereby you can do what you like with the property without her signature. If you decide to rent the property, you can rent it out, but you do need the lender’s consent
