# SignatoriesOutOfOrder (/docs/errors/chain/SignatoriesOutOfOrder)

The `other_signatories` list is not sorted in strictly ascending account order, which the multisig pallet requires for a canonical account derivation. Sort the list and remove duplicates before resubmitting.

Declared by the `Multisig` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).
