A warrant issued in a debtor's maiden name remains enforceable unless the address is incorrect, which would render it invalid. There are numerous precedents supporting this position, though they are too extensive to list comprehensively here.
It is crucial to avoid completing a PE2 or TE9 form or disclosing your current address. Doing so would immediately activate CPR 75.7(7), enabling the council to issue a new warrant at your updated address. This action would effectively reset the process, inviting bailiffs to resume enforcement even before the authority has addressed your Rule 6 notice.
Putting your car on someone else's driveway prevents the bailiff from removing it; otherwise, the enforcement is in breach of Paragraph 14(6) of Schedule 12 of the Tribunals Courts and Enforcement Act 2007.
While suggesting PE2 or TE9 may come from a place of goodwill, following this route in your particular situation could lead to unintended consequences, ultimately working against your interests.
