With a few basic exceptions, such as clothing, bedding and furniture (as well as 'tools of a trade', where applicable), bankrupts lose all of their possessions. They also lose their interest in their home which (if they own a property outright or have a mortgage) normally means that they'll actually lose the house.
Bankrupts also lose their interest in any business that they run, which usually results in the closure of the business. They also face considerable difficulties in opening and operating a bank account. See here for full information:
