What should we do with checks that never cleared the bank?

Two clocks start when you write a check.

The bank’s clock runs six months. Under UCC section 4-404, a bank does not have to pay an uncertified check presented more than six months after its date, although it may still pay it in good faith. After about 180 days you can no longer count on the check clearing, and the payee may never have received it.

The state’s clock runs years. Uncashed checks are unclaimed property, and once the dormancy period passes you report and pay the amount to the state instead of keeping it. Delaware, where many companies are incorporated, sets 5 years for vendor payments, with reports due 1 March, according to NAUPA’s Delaware page. Other states differ, so check the states where your payees are.

Neither clock turns the money into yours. Current answers such as AccountingCoach mention unclaimed property but give no entries, and a recent Beancount guide gives entries with cash and payables posted the wrong way round and cites the rule as section 4-405. Here are the entries with the signs checked, on five checks from one month end.

Five checks on one reconciliation.

The reconciliation ties, so nothing looks wrong. But 5,875.50 of the 33,505.50 in outstanding checks is stale, and the oldest has sat on every reconciliation for a year. That is cash shown as spent that may never leave the account, and a payee who may still be waiting to be paid.

The useful work happens before six months. Check #1007 is 150 days old and turns stale on 30 November. A call now usually ends in either a deposit or a request to reissue, which is cheaper than chasing a payee after the check has expired.

The entries, dated in the open month.

All dated 31 October 2026, the open month,
even though the checks were written in
March 2026 and November 2025.

#0988, lost, reissued
  Dr Cash                          4,115.50
     Cr Accounts payable               4,115.50
  Dr Accounts payable              4,115.50
     Cr Cash  (new check #1046)        4,115.50

#0951, payee unreachable
  Dr Cash                          1,760.00
     Cr Unclaimed property payable     1,760.00

Later, when the state's dormancy period
has passed and the holder report is filed
  Dr Unclaimed property payable    1,760.00
     Cr Cash                           1,760.00

Both stale checks were recorded correctly when they were written. Nothing about March or last November was wrong, so the fix belongs in October. Voiding a check back to its original date would change the cash balance of a month you have already closed and reported.

The unclaimed property payable is the account most teams skip. Crediting other income instead overstates profit by 1,760.00 and hides an amount the state may later ask for. Keep the payee’s name, last known address and the check number with the balance, since the holder report asks for them.

Bank reconciliation, operating account
31 October 2026. Every amount is an example.

Before the entries
  Balance per bank statement        212,640.00
  Add deposit in transit              9,800.00
  Less outstanding checks (5)       -33,505.50
  Adjusted bank balance             188,934.50
  Balance per books                 188,934.50

After the entries
  Balance per bank statement        212,640.00
  Add deposit in transit              9,800.00
  Less outstanding checks (4)       -31,745.50
  Adjusted bank balance             190,694.50
  Balance per books                 190,694.50

Book cash rises by 1,760.00, the bank balance does not move, and the list of outstanding checks drops from five to four, with #1046 replacing #0988 on a fresh date.

How Rivane handles old checks today.

Rivane ages outstanding checks from the books, the place they actually go stale: a posted cash payment with no matching bank line is an outstanding check, aged from its posting date and flagged stale at 180 days. Unmatched lines on the bank statement are kept in a separate list, so a bank fee is never mistaken for an old check.

              date, the check date plus 180 days
past it       printing or posting the check is
              refused: "void and reissue it instead"
reissue       one action voids the old check, reverses
              its entry, and creates the replacement
              linked to it; a check is reissued once
void reason   stored in its own field, not in the memo

The rule we would point to first: a check past its stale-after date cannot be printed or posted, and reissuing it is a single action that keeps the old and new checks linked. The auditor can follow #0988 to #1046 without a spreadsheet.

The limits worth knowing. The aging is a report from the Rivane API today, not yet a screen. A void marks the original check entry as voided in its own month rather than posting a new entry dated today, so for a check from a month you have closed, book the restoring entry as a manual journal in the current month as shown above. Rivane has no unclaimed property workflow: the liability and the later payment to the state are manual journals.

A short monthly habit.

Age outstanding checks every month. Contact payees once a check passes 90 days. At 180 days, reissue it or move it to an unclaimed property payable, dated in the open month, and never to income. Clear that payable when you file with the state.
