I called the monthly reconciliation a bookkeeping habit, and the statute calls the statement a clock with 2 deadlines on it

I had assumed the bank carried this risk. For 3 years I told founders that reconciling the business account monthly was a bookkeeping habit, somewhere between tidy and optional, and that the bank would sort out anything obviously fraudulent. That was bad advice. The statement is not a report on what happened, it is a clock, and the law starts it whether anybody in your company opens the file or not.

The question of how to read a business bank statement turned out to have a legal answer rather than a bookkeeping one. I went looking for it after a company I know lost 11,000 dollars to altered cheques and got nothing back, and the reason was 1 sentence in the uniform commercial code that nobody in the room had read.

A caveat before the rules. The UCC is a uniform text that each state adopts with its own variations, and what follows is that uniform section rather than your state’s enactment. I read the uniform text, not 50 of them.

What the bank owes you, in 3 fields

I would read the bank’s obligations first, because they set the size of yours. Section 4-406 starts with the bank’s side. A bank sending a statement must either return the paid items or give you information “sufficient to allow the customer reasonably to identify the items paid”.

Then it defines sufficient, and the definition is narrower than most statements suggest. The statement provides enough “if the item is described by item number, amount, and date of payment”. Three fields. Not the payee, not the memo line, not an image.

There is a retention rule attached. If the items are not returned to you, whoever keeps them must retain them or keep the ability to produce “legible copies” for 7 years, and you may ask the bank that paid an item for the item or a legible copy of it. Ask for it before a dispute rather than during one.

What you owe, and why the word is promptness

The customer’s duty is in subsection (c), and it has 2 halves. You must “exercise reasonable promptness in examining the statement or the items” to see whether any payment was unauthorised because of an alteration or a signature that was not authorised. And if the statement should reasonably have shown you the problem, you must “promptly notify the bank of the relevant facts”.

I misread this duty for years as a duty to find fraud. Notice what it is not. It is not a duty to catch everything, and it is not about fraud you could not have seen. It is about what the statement in front of you shows, which is why the 3 fields above matter so much: they define what you can be expected to spot.

The 2 deadlines that decide who pays

This is the part that cost that company 11,000 dollars, and I had never read it.

The first deadline is the same wrongdoer rule in subsection (d). If the bank proves you failed the duty in (c), you lose the right to assert your unauthorised signature or an alteration where the bank also proves it suffered a loss, and you lose it for further items by “the same wrongdoer” paid in good faith before your notice and after you had a reasonable time, “not exceeding 30 days”, to examine the statement and tell the bank.

Read that as a fraud pattern rather than a legal clause. Somebody who alters 1 cheque alters the next one 3 weeks later. The first loss may be arguable. Everything after your 30 days is not.

The second deadline is the one I would tattoo on a bookkeeper, and subsection (f) states it without apology. “Without regard to care or lack of care of either the customer or the bank”, a customer who does not discover and report an unauthorised signature or alteration within 1 year of the statement being made available is precluded from asserting it. No exceptions for a good excuse. No exception for a careless bank.

How the 11,000 dollars actually went

The sequence matters more than the total, and I have gone back over it twice since. A supplier cheque was altered in June, for 1,400 dollars, and nobody noticed: the statement was downloaded, filed and never compared against the payment run. The same person altered 3 more cheques in July and August, for 9,600 dollars between them, and the company found out in September when a supplier chased an invoice it had supposedly been paid.

By then subsection (d) had done its work. The June item was arguable, because the bank would have had to prove its own loss from the delay. The July and August items were not arguable at all: same wrongdoer, paid in good faith, after the company had far more than a reasonable time not exceeding 30 days to examine the June statement and say something.

I cannot tell you whether a different argument would have saved the June cheque, because they settled rather than litigating, and I do not know what their deposit agreement said about reporting windows. The shape is what I am sure of: 1 unexamined statement converted an arguable 1,400 dollar loss into an unarguable 11,000 dollar one.

The clause that cuts the other way

Now the clause in your favour. Subsection (e) is the one a bank would rather you skipped, and I would put it in the same folder as the deadlines. If you prove the bank failed to exercise ordinary care in paying the item, and that the failure substantially contributed to the loss, the loss is divided between you and the bank according to how much each failure contributed.

Bad faith removes the preclusion entirely. If you prove the bank did not pay the item in good faith, subsection (d) does not apply at all. So the 30 day rule is a strong default. The year in (f) is the iron one.

Few companies get this far. My instinct is that most never reach the argument at all, because reaching it requires having examined the statement in the first place. You cannot allege the bank was careless about an item you never looked at.

What a good statement review looks like on paper

I keep the review deliberately dull. A column of debits, a column of what we authorised, and a note against anything that does not tie out on the day I look.

The 3 fields the statute names make that possible, and they also show where a bank is being unhelpful without being non-compliant. A statement that gives item number, amount and date of payment meets the standard. A statement that also carries the payee makes the review 4 times faster, and I still find it odd that the slower version satisfies the law while costing the customer the very promptness the same section demands of them.

Anything unmatched gets an email the same day, with the item number in the subject line. Two sentences, a date, and a request for the legible copy. It has never taken me longer than a coffee.

The other number on the statement: when money is usable

Reading a statement well also means reading the availability, which is a different rulebook. Regulation CC sets the outer limits: for a local cheque and certain others, including cashier’s, certified and teller’s cheques, funds must be available for withdrawal not later than the second business day after the banking day of deposit. For a nonlocal cheque, the fifth business day.

Those are ceilings rather than promises, the same section carries exceptions in paragraphs (d), (e) and (f), and the reason to know the numbers anyway is that a deposit held past them without an exception is the only part of a statement where you have a clean argument rather than a negotiation. The practical use is narrow but real: if your statement shows a deposit sitting unavailable past those days without an exception applying, that is a conversation with the bank rather than a fact of life.

What I do now, monthly, in 20 minutes

My guess is that 20 minutes a month is the whole cost of staying inside both deadlines, and I have not found a shorter routine that does it. Pull the statement the day it is available rather than when the accountant gets to it, because both clocks start from availability and not from your attention.

Match every debit against the 3 fields the statute names: item number, amount, date of payment. Anything you cannot tie to a payment you recognise is a question that same day, and the request for a legible copy is free and available for 7 years.

Write the notice in email rather than a phone call. The statute turns on whether you promptly notified the bank of the relevant facts, and a phone log is a worse record of that than 4 sentences with a date on them.

And put a calendar entry 11 months after each statement, which sounds absurd until you read subsection (f) again. It is the cheapest protection against the only deadline in this section that forgives nothing.

Questions we get

These arrive most often from bookkeepers rather than founders, which tells you who actually reads statements. I have not found a way to make that less true.

What exactly is the duty to examine a statement? Reasonable promptness in examining the statement or the items for an alteration or an unauthorised signature, and prompt notice to the bank of the relevant facts if the statement should reasonably have revealed the problem.

Who pays for an unauthorised signature on a business account? It depends on timing and care. Fail the duty in (c) and the bank proves a loss, and you are precluded from asserting it; prove the bank lacked ordinary care and the loss is shared; prove bad faith by the bank and the preclusion does not apply.

How long do I have to report an alteration of an item? Two limits run at once. Practically, a reasonable time not exceeding 30 days protects you from the same wrongdoer’s later items, and absolutely, 1 year from the statement being made available ends the claim whatever either side did.

What must a statement of account contain? Either the paid items themselves or information sufficient to identify them, and the statute says item number, amount and date of payment is sufficient. Anything beyond that is your bank being helpful rather than compliant.

Can I still get legible copies of old cheques? For 7 years after receipt of the items, yes, and the bank that paid the item must provide the item or a legible copy in a reasonable time.

A short digression about the word statement

A statement sounds like a record of the past, something to file. This section treats it as a notice served on you, with consequences for ignoring it, and the difference between those 2 readings is the difference between a bookkeeping task and a legal deadline. I still find it strange that banks send the thing monthly without ever mentioning the year. Anyway, back to the 3 fields.

What is not settled here

Your state’s version. I read the uniform text, states vary, and a lawyer in your state is the person who can tell you which words changed.

What courts accept as reasonable promptness. That is case law, this piece is the statute, and I have not read the cases.

What your own bank agreement adds. Deposit agreements often set shorter reporting windows than the statute, and I do not know what yours says, which is the 1 document I would read next.
