Please ensure that you make no decision without obtaining full information from a UK Insolvency expert. This is a serious step and should not be taken until you have a clear understanding of what is involved and whether UK bankruptcy is suitable to your circumstances.have been having a look, do you inform your mortgage company you intend to file for bankrupcy and then hand the keys in... or do you just (And I don't mean JUST as I know it is a big step) hand the key in and then the shortfall after the house is sold is the unsecured loan....?
