What Setoff Means for Account Holders
Setoff is a bank's right to use funds in your deposit accounts to cover a debt owed to the bank. If you have a loan, credit card balance, or other obligation with the bank, and you also have a multi-party account there, the bank can apply your share of the account balance toward the debt.
Without qualifying any other statutory right to setoff or lien and subject to any contractual provision, if a party is indebted to a financial institution the financial institution has a right to a setoff against the account.
A.R.S. § 14-6227The statute limits the setoff to the proportion that the debtor is beneficially entitled to under the account. If there is no clear evidence of each party's share, the bank assumes an equal split among all parties. So on a two-party account with no documented ownership percentages, the bank could offset up to half the balance.
Protecting the Non-Debtor Party
This rule matters most when one person on a joint account has debts and the other does not. The non-debtor party's share is protected from setoff. A bank cannot claim a security interest in the deposit account beyond what the debtor actually owns. But proving ownership proportions can be complicated if the account was set up without any formal agreement about who contributed what.
The amount owed to the bank determines how much the bank can take. If the debtor owes $5,000 but their share of the deposit accounts is only $3,000, the bank's setoff is limited to that $3,000.
For families managing joint accounts or multi-party accounts, understanding this statute helps avoid surprises. If one account holder takes on debt with the same bank, the other party's funds could be caught in the crossfire unless ownership shares are clearly documented.
