Yes, it is possible to make withdrawals to a bank account with more than one owner, provided that the Betano account holder is one of the co-owners of the bank account.
Rule for Joint Accounts
Your withdrawal will be processed if:
Your name appears as one of the account holders of the bank account (co-owner).
Your joint bank account has already been validated on Betano.
