Responsible person

Whoever has control of the premises or event for its main use — the person who holds the Martyn's Law duty.

The responsible person is the individual or organisation with control of the premises (or event) for the relevant use. It is usually the operator — not always the landlord, and not a hirer. Legal responsibility cannot be passed on by a hire contract, although tasks can be shared.

Identifying the responsible person matters because the duties fall on them. Where control is genuinely shared or unclear, it is worth getting that pinned down early.

Who it affects: Owners, operators, licensees, event leads and anyone who controls a venue.
