I''ve decided I have nothing to hide by posting in here, so long as I keep it factual. I doubt STBX can dispute any of what follows.
I''m looking for your estimates of division here. The main issue is division of net proceeds of sale of the house, and whether that should be adjusted from 50:50 in his favour.
Ages: 42 (both)
No children from the marriage.
Cohabited 2 years, married 11.5 years, separated 3.5 years
Reason for separation - Adultery, though I''m told this is irrelevant when it comes to financial proceedings.
Incomes at separation: £20K each
Incomes now: me £20K; him ZERO (mature student)
Potential incomes in future: me £20K, him £30K+
Outgoings? Trickier!
Me: I''m with a new partner, we have a disabled son, partner is full-time carer for son. We rent a house which we had to furnish from scratch. My earnings are the only income into household. Outgoings = entire Income!
STBX: Currently living with family, but still paying costs for
FMH. He kept all furnishings etc.
Assets: cars of equal value, pension funds of equal value, nothing else. We both had savings of £3K at separation but suspect we''ve both spent that.
Liabilities: me None; STBX probably student loan.
FMH: value £100K, probably sell at auction for £80K, net proceeds estimated £50K. Both contributed equally to deposit of house, and to mortgage & household expenditure during marriage.
Situation:
STBX chose to stay in FMH following separation, was working, mortgage and all costs of FMH while I paid rent for new home elsewhere. House went on the market but no success at sale. STBX made decision after 18m to move out and become student (zero income), left FMH empty, did not ask if I wanted to move back in (didn''t even tell me what he''d done for a few months), did not ask me at that time to resume contribution to mortgage & bills. I presumed he''d made suitable arrangements given his decision (we weren''t exactly talking!) After 18m of studying (so 3y separated) he announces (realises?) he can no longer afford mortgage & costs, so starts nagging me to contribute - but I have no spare income due to paying rent etc for my own home.
I''m guessing the question comes down to whether I am responsible for the costs of the
FMH after he decided to give up his job and move out. I know he has no plans to move back, and the house is probably going to auction soon.
Please let me know if more info is needed. Thanks.
