Note that the expedited recredit process only applies to ‘substitute checks’ under the Check 21 law.
Reporting Errors
If you find an error in your checking account, and a substitute check was involved, you should report it promptly. You have 40 days from the time your bank provided the substitute check to you (or from the statement date where the error appears).
You should report the error in writing. Describe what’s wrong, how much is at stake, and exactly which check the bank needs to research. The more detail you can provide the better.
Time Frames
The bank has up to 10 days to research your claim. If they cannot resolve the issue, they must add the funds in question to your account (the ‘expedited recredit’) until they complete their research. The maximum credit you’ll receive during this period is $2500, so larger errors can be a problem.
The bank has up to 45 days to complete their research and either reject or accept your claim.
