If a bailiff seizes goods that are subject to a Hire Purchase (HP) agreement, seek advice urgently. Goods on HP do not belong to you until you make the final payment, but there may be circumstances in which they can be seized.
If goods have been seized wrongfully, then the owner of the goods can apply for them to be returned. If the goods belong to family or friends then a receipt or credit agreement may be required. They can take items jointly owned, however they may take the portion of capital which belongs to you.
