Enforcement agents must on request show the debtor their identity and their authority to enter the premises. Paragraph 26 of Schedule 12 of the Tribunals, Courts and Enforcement Act 2007 states:
(1) The enforcement agent must on request show the debtor and any person who appears to him to be in charge of the premises evidence of:
(a) his identity, and
(b) his authority to enter the premises.
The warrant is the authority to enter premises to take control of goods. The enforcement address is always printed on the warrant.
Bailiffs do not need to show a paper or "wet signature" warrant. It can be shown on a device, and you can take a picture of it using your phone.
The moment a bailiff shows you a counterfeit warrant, or one that appears to have been made on a home computer, all enforcement authority and fees are revoked.
A private company cannot grant itself authority to enter premises by creating a document on a computer. The court itself must issue this authority.
This is a breach of paragraph 26(1)(b) of Schedule 12 of the Tribunals, Courts and Enforcement Act 2007.
You can now bring legal action under paragraph 66 of Schedule 12. Follow this article to begin proceedings.
Then use the law to get a certified copy of the warrant:
Nothing changes if the bailiff company shows a real warrant after attending. Paragraph 26(2) states:
(2) The request may be made before the enforcement agent enters the premises or while he is there.
If the bailiff is carrying a fake warrant or refuses to show it, call 999 and report a disturbance in progress and that you are in imminent danger.
When police arrive, explain that the individual is committing an offence under section 40(1)(d) of the Administration of Justice Act 1970:
Punishment for unlawful harassment of debtors
(1) A person commits an offence if, with the object of coercing another person to pay money claimed as a debt, he:
(a) harasses the other with demands calculated to cause alarm, distress or humiliation;
(b) falsely represents that criminal proceedings lie for failure to pay;
(c) falsely claims to be authorised in an official capacity; or
(d) utters a document falsely represented to have official character which he knows it has not.
Also refer to section 3 of the Forgery and Counterfeiting Act 1981:
The offence of using a false instrument
It is an offence to use a false instrument, knowing or believing it to be false, with the intention of inducing someone to accept it as genuine and act to their prejudice.
Making a forged document to obtain a money transfer not sanctioned by law is also an offence under section 7 of the Fraud Act 2006:
Making or supplying articles for use in frauds
(1) A person is guilty of an offence if he makes, adapts, supplies, or offers to supply any article:
(a) knowing it is designed or adapted for use in connection with fraud, or
(b) intending it to be used in the commission of fraud.
Show the police officer a specimen real warrant of control (download it here) or display it on your phone. Ask the police to place the bailiff under arrest.
This may itself be a criminal offence. If the police officer refuses to act or says it is a "civil matter", record their name and take a photograph. They may be committing an offence under section 26 of the Criminal Justice and Courts Act 2015:
(2) A police constable guilty under this section is liable to imprisonment for up to 14 years or a fine (or both).
(5) A police constable is to be treated as exercising their powers improperly in the following cases:
(a) fails to exercise a power or privilege of a constable
(b) does so to achieve a benefit or detriment;
(c) and a reasonable person would not expect such failure.
Then contact me, and we can pursue a private prosecution under section 1 of the Magistrates Courts Act 1980:
On an information being laid before a justice of the peace that a person has, or is suspected of having, committed an offence, the justice may issue:
(a) a summons requiring that person to appear before a magistrates' court, or
(b) a warrant to arrest that person.
