Thank you for your question
My name is Clare
I shall do my best to help you but I need some further informtaion first
What agreement has been reached?
You can make any agreement that you wish - but the only way that it will protect you is if it is turned into a Court Order within divorce proceedings.
Anything less will mean that your ex can always make a further application
Depending on how long you have lived together anything less than a 50/50 share of the assets could leave you at risk.
I hope that this is of assistance - please ask if you need further details
