There's this little provision of the UCC in your state. Take a look at Article 4, section 4-405 in your state's UCC, and you will probably see that once you know of your depositor's demise, you may (not must) pay checks for up to 10 days after the date of death. The assumption is that the checks have to have been issued before death, of course, so watch for any creative attorneys-in-fact who attempt to pull funds out "post mortem," after their authority has ceased to be effective. Their checks should be rejected "Account owner deceased" or "no authority to pay."
Suppose your customer died on Tuesday, March 1, and you learned of the death on Tuesday, March 8. You'd be able to honor checks through March 11 only (ten days after death).
And I think you'll also see in ยง4-405 the phrase "unless ordered to stop payment by a person claiming an interest in the account." So, if a creditor of the estate figures out you're holding the checking account at your bank and comes in on March 9 to tell you to stop paying checks, the creditor has an interest in the account, and you'd have to stop paying any more checks at once.
And, after the tenth calendar day following the date of death, no further checks would be properly payable from the account.
