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 long have you lived together in total, how much is the property worth and how much is outstanding on the mortgage?
What income do you each have?
The good news is that yes you can indeed offset your claim on her property against her claim on your savings
Given the medium to short length of the relationship neither of you has substantial claims on the other - although the considerable difference in your incomes means that a small lumo sum in lieu of spouse maintenance may be a real possibility.
I hope that this is of assistance - please ask if you need further details
Whether it is income or savings is not relevant to the issue - it is money that is there!
You are most welcome - I hope all goes well
