These individuals are employed predominantly by the courts to
enter your property and remove goods that can and will be sold at
auction in an attempt to cover any debts you owe a lender who has
previously issued a County Court Judgement (CCJ) which you have
failed to pay.
If you can't repay your debts you may be declared bankrupt. Any
assets you have would be used to raise money to distribute to your
creditors (those people you owe money to). If you own a home you
may well be expected to sell it.
