Thank you for your question
My name is Clare
I shall do my best to help you but I need some further informtaion first
Is there any reason why you have not yet forced the sale?
Are you now willing to commit to court action?
Has she paid for any structural alteration or improvements to the property?
In that case there is no reason why you should not receive your full 50%!
Technically yes you can claim.
I would include it in the claim but make it an area for negotiation
You are most welcome - good luck
