To remove an ex's name of an excisting mortgage, normally you would have to fill out a ''transfer of equity form'' from the excisting mortgage lender to have a name removed. Would I still have to fill one out if I would remortgage my house with a new lender which will be in my sole name?
You will need to have the title put into your sole name at HM Land Registry, and you will therefore need to both execute a land registry form TR1 transferring the title from your joint names to your sole name.
