Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
How much is the house worth and how much is outstanding on the mortgage?
What other assets are there and what income do you each have?
When was the Decree Absolute?
Was there no financial settlement at that time?
Have you also remarried?
Did you have legal advice at that time
Just to check - the house is currently worth £185,000 and there is a mortgage of £175,000 outstanding?
So why is he asking for £50,000?
What nonsense - he has no such claim
What do you actually wish to do with the house?
have you spoken to the mortgage company about this?
