The bailiff called about a fine owed by someone else

The bailiff may only take control of goods that belong to the debtor.^[1]

If the debtor is your son, relative, or a housemate using your address for correspondence, the bailiff is unable to execute the warrant of control.

It is not for you to tell the bailiff where the debtor is, and you can tell the bailiff to quietly leave the property.

If the bailiff takes a money transfer from you under the pain of taking your belongings, you have a right to recover the money together with your costs,^[2][3] by making a small claim.^[4]

You can reclaim the money by making a chargeback.^[5]

If a money transfer was taken by the bailiff knowing you are not the debtor, he may have written on the receipt that you paid voluntarily,^[6] to indicate you willingly gave the money on the debtor’s behalf. This commits an offence.^[7][8]

If bailiffs remove your goods for someone else's debt, then make a third-party claim,^[9] and you may recover damages for the interference with your goods,^[10] together with your costs.^[2][3]
