to the housing officer, don't know anything about ha but it seems silly as he doesn't live there any more. Out of interest does his mail still go there?
As for divorce, I am learning more about that every day!
If you have been separated 2 years, you can apply for a divorce on that basis. However he would have to agree. I actually lived in the same house with my STBX but we were separated. We did not sign a separation agreement, I just explained to my solicitor that for several years we had not lived as husband and wife (i.e. other than the obvious he did his own washing, cooking etc)
As for the finances, unless you live in Scotland where the date of separation is more relevant, you will both have to provide disclosure as to what you both have up to when you have any assets valued - not the date you separated. If his circumstances have changed since he moved out he will have to own up to it (ditto to you winning the lottery!)
Bank statements, pay slips, tax returns, pension etc will have to be provided. Obviously this can be tricky when someone is self employed etc, but it can be quite normal to request 3 yrs worth of bank statements to show any paper trail of money diverted etc
Hope that helps...I hate it when you go on here with a genuine concern and people go off at a tangent about something else!!!
