Advice please

A couple of years back our non Ltd business went bust, the last straw came when the landlord hired a baliff to come in and ring fence the stock which he later sold to fund our rent arrears. Prior to this we were getting calls from various suppliers chasing for money owed and one in particular wouldn't settle for any form of payment scheme we tried to set up. Before the baliff came we even offered them the choice of coming in and taking back any of their stock to reduce the money owed but they refused.

Anyway after closing some suppliers contacted us at home and either by letter from themselves or via a court and we reached payment plans with them to pay off the debts. This particular one though we hadn't heard anything from so we assumed they written off the debt against their tax, that is until last August when we received a county court letter asking us to pay or offer a payment plan. It was unusual from the others though in that the supplier had included all our house details in the claim to the court.

We sent back the form offering to pay a monthly amount which was accepted by the court, however a short time later we got another letter stating the supplier wanted a re-determination. We couldn't attend court but sent a letter explaining our circumstances and the result was that our offer of payment was accepted for 6 months after which time we had to file and serve upon the court a schedule of assets & liabilities and a schedule of income & expenditure together with supporting documentation to evedence the figures set out in the 2 schedules. This will be due in March.

As said we've not had anything like this in the past so does anyone have any idea what the supplier can gain by taking this approach ? Do they think we've got money stashed in an offshore account or something ?

I must state that the business was just a small retail shop so the supplier certainly knows that there was no fortune to be made, it was just a hobby that we turned into a business (bad mistake). The fact that they sent house details with their original claim makes me wonder if they are looking to put a charge on the house. Can they do that ?

Would also appreciate just what supporting documentation you think we should send in i.e. we've no savings, the house is in negetive equity, no working car etc.

Thanks in advance.
