transfer of deeds when mortgage still in both names

I am very confused and wondered if anyone could help....

I have spent the last 3 years going through court for my son and my house. I have a non molestation order and non residence order against my ex partner. I have also just managed to get a court order for the transfer of the house deeds into my sole name.

My solicitor has told me that i firstly need to ask my mortgage lender to take my ex parter off of the mortgage. If they wont do this then at least their agreement to the deeds of the house being transferred into my sole name. However, having spoken to the lender they say that a deed cannot be transfeered to me if they dont agree to taking my ex partner off. They say thst a deed must be in the same name as the mortgage.

I doubt that the lender will take my ex partner off the mortgage as i will not be seen as a good financial prospect being a single mother of a disabled child:A living on benefits, even though ive been paying for the mortgage alone for the last 2 and a half years. He is not a good prospect either as the last i heard he wasnt in employment.

Has my time been wasted by getting a cout order to transfer the deeds as it appears thst it is useless if the lender dont agree to transfer the mortgage. it will be made impossible to sell the house if my ex partner is still on the deed due to the other orders preventing him from contacting me or being anywhere near me.

Thank you in advance
