# Reject Transaction Rejecting a send transaction involves actions by the proposer and co-managers. 1. By default, the proposer gets asked to approve the transaction they proposed as mentioned in [Propose Transaction.](/sui/user-guide/propose-transaction.md) 2. The co-manager(s) can reject the proposed transaction and the threshold must be met to execute the rejection. Please read next section - Co-Manager(s) Actions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
