Thank you, yes you are pretty spot on with your assumptions. The court order was for him to remove me from liability regarding the mortgage within 28 days of said order, which obviously he hasn't done. He wants to do it now as he has been stuck in a variable rate mortgage for goodness knows how long now, and is keen to obtain a better rate.
I'm still named on the deeds of the house and with the land registry, the forms I have been sent are for me to sign to transfer propriety of the property in to his name, and agreeing to relinquish any financial claim on it.
