# SenderInSignatories (/docs/errors/chain/SenderInSignatories)

The multisig sender was included in the `other_signatories` list, but that list must contain only the remaining signatories. Remove the sender's own account from `other_signatories` before resubmitting.

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