You had every right to have a whinge love! The way my solicitor explained the mortgage stuff was: Think about when you go to the building society to get a mortgage - they give so times so much to the greater earner, then a lesser proportion to the lower earner (the amount you can borrow). So, even if a joint owner doesn't live in the property, he is still liable for the larger amount - as he was the "first" on the mortgage. So, in my case, most of our mortgage was based on his income. (Actually I wasn't working when we moved here - I was doing my OU degree and bringing up 4 kids). So, just because Lycra-man has gone the building society don't care. I could say, yes, you pay me XXX for maintenance etc., and I will cover the mortgage. Then, things get tight financially for me - so I default on the mortgage - so the Building Society go after him - as the main earner/borrower.
Now, in your case, if you earn less, then you should pay less. If you take over the whole mortgage, then the above applies to you, as it does me.
My circumstances are similar to yours re: spousal maintenance. I actually earnt more than Lycra man when we married; he moved into my house that I'd bought and I carried on paying the larger percentage, if not all, of everything for 3 years. Then when ES came along, I gave up work. My solicitor says that I therefore stopped paying into a pension. So I can have spousal maintenance (she is in no doubt about it whatsover) because I gave up work, as we both agreed, to bring up a large family. Then I got my degree, trained as a mental health nurse, and only worked part-time. This suited Lycra Man and me - we never saw the point of having kids and paying someone else to bring them up.
Change your lawyer, Wisey! Or give him a rocket!
Oh, must just say, Lycra man popped round to pick up YS this morning, me and daughter convinced he's either had a spray tan (a nice shade of tango) or he's jaundiced.
