Hi Michael,(posted 7828 days ago)I am sorry to hear of all the hassles. I know when someone has an affair it is often difficult to think on a day to day basis however I am sure if you have the mortgage account number as others have said you can contribute towards it even though it is in your wife's sole name. As her husband you must have a very good chance of having a vested interest and you need to deal with a solicitor who has vast experience of this as I am sure you must have numerous rights, something which, believe it or not, you have none if you are not married and not on the mortgage/deeds. You don't mention whether or not you are on the deeds of the property, if you are then this is a very good sign, if not then unfortunately you are going to have a fight on your hands, however the court system will be the only way through this. Please don't let this person destroy you. I spent a long and wearisome 5 years fighting my ex after he left with my best friend, he is still, unsuccessfully trying to hurt me and failing miserably. My fiance (yes I'm getting married again despite everything) lost his house through his ex-wife's extra-marital affair but there is life on the other side. Good luck and I hope it all works out for you in the end.
