My Sister got divorced and her ex remarried. My sister still lives in the matrimonial house with her kids, pays all the bills, mortage etc with no financial input from her ex. The mortgage lender won't let Sis take the ex off the joint mortgage, back up for them I suppose if she becomes unable to support it on her own, she is managing at the moment.
Her worry is that her ex still has a claim to any equity in the house as he is still jointly named on the title deeds. Ex has verbally told her that he no interest in the house and she can keep it but is there a legal document, valid in the UK, that he can sign to relinquish all claim to any value in the property?
Sis is concerned that if Ex dies her home would be classed as part of his estate or if Ex gets into financial difficulties he could force her to sell up to bail himself out.
I have heard of Quit Claim deeds but are they valid in the UK?
Any ideas
