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 and debts are there and what income do you each have?
How old are you both and are there any children involved?
Did he bring any assets at all to the relationship - where was he living before moving in with you?
Is there a paper trail of these large lump sums he received?
