Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
What assets do you each have now and how much do you each earn?
What about pension provision?
Excellent (well for this purpose)
Given all that you have said then there is little chance that your ex will be able to make any further claims off you as and when there is a divorce.
The matrimonial assets were shared equally between you both, you are evenly matched financially and able to make adequate provision for yourselves
Please ask if you need further details
