If two bailiffs turn up and leave a notice, do they both have to sign their names on it?


No

To take control of goods, a person must have a certificate,[1] unless he is exempt,[2] otherwise he commits an offence.[3]

The bailiff is allowed to take other people onto the premises,[4] to assist him,[5] but they may not remain on the premises without the bailiff.[6]
