If a relevant partner of a local authority has reasonable cause to suspect that a person is an adult at risk and appears to be within the authority’s area, it must inform the local authority of that fact.

If the person that the relevant partner has reasonable cause to suspect is an adult at risk appears to be within the area of a local authority other than one of which it is a relevant partner, it must inform that other local authority.

If a local authority has reasonable cause to suspect that a person within its area at any time is an adult at risk and is living or proposing to live in the area of another local authority (or a local authority in England), it must inform that other authority.

For the purpose of this section a relevant partner of a local authority is a person who is a relevant partner of the authority for the purposes of section 162.
