If the sheriff officer breaks a lock or window which subsequently needs to be replaced, the creditor might pass on the cost of replacement and repair to you.
At any stage, you can make arrangements to pay the sheriff officer part or all of the debt.
You have the right to ask for identification from the bailiff, and they are obliged to show you their ID if you request to see it. They should have a booklet carrying the Scottish court service crest, with photo ID inside.
You can make a formal complaint against a sheriff officer by writing to the Sheriff Principal if you feel that their behaviour has been unreasonable.
