we are both in good health. My stbx has pensions i don''t. One is around worth £31,000 the other less but he has not paid into them since 2005. I purchased the house in June 2003 and we got married in Nov 2008.
So what you have is a shortish and childless marriage, assuming there is no huge difference in income there will be little reason to move away from contribution, so he has contributed, but how much, and to what extent he should be compensated is a matter for you and he to decide.
If you have trouble deciding what would be fair think along the lines of what is it going to cost him to house, rent deposit ect, it may also be worth speaking to a mediator, if you can stay away from court, the cost can be eye watering, mediators are a good starting point.
How much do you actually earn, what dies he earn? You both have the right to make a claim, that does not mean the claim would be sucsesfull, the chances are any claim made would be very limited, sometimes to avoid court it could be best to make a small offer to end the matter once and forall, if you do only hand over money once you have a Consent Order.
It may be worth spending an about with a solicitor who can take some fine detail and advise you further, or post more detail here.
