How to document a verbal change order — and what happens when you don't

Write it down the same day and send it to the person who approved it. A same-day email that states the scope, the price, the schedule impact, who approved it and when — and asks them to confirm — is the cheapest protection available to a contractor. It doesn't replace a signed change order, but when a signed one never arrives, it is often the best evidence that the change was authorized at all.

The gap between how contracts work and how jobs work

Nearly every standard construction contract says changes must be authorized in writing before the work proceeds. The AIA A201 general conditions, the ConsensusDocs forms, and almost every custom owner agreement contain some version of that clause.

Nobody builds that way. The owner calls at 7:40am, says move the panel and add two circuits, and wants to know if it affects the finish date. The crew is standing there. If you wait for a signed change order, you lose the day. So you do the work and chase the paperwork later — and "later" is where the money disappears.

This isn't a discipline problem. It's a structural mismatch between how contracts allocate risk and how a live job actually moves. The fix isn't to stop taking verbal direction. It's to make the written record follow within hours instead of weeks.

Are verbal change orders enforceable?

Sometimes — and that "sometimes" is exactly the problem, because it means the answer gets decided by a judge, an arbitrator, or whoever has the better documentation.

Courts in most states have mechanisms that can let a contractor recover for work authorized verbally, even when the contract required writing. The common ones are waiver (the parties' conduct showed they didn't intend to enforce the written-change requirement), course of dealing (they'd handled prior changes the same informal way), and unjust enrichment or quantum meruit (the owner received the benefit of the work and shouldn't keep it for free).

But each of those requires you to prove what was agreed. And the party who has contemporaneous records — written at the time, not reconstructed a year later from memory — is in a materially better position than the one who doesn't. The law is not the obstacle. Proof is.

The practical version: you may well have a legal path to get paid for verbally authorized work. You will spend far more getting there than the five minutes it would have taken to send an email that afternoon.

What to capture, every time

A useful record answers six questions. Miss any one and the record is arguable.

  1. Who authorized it. Name and role. "The owner said so" is weaker than "Dana Whitfield, Northline Properties."
  2. When. Date and time of the conversation, not the date you got around to writing it up.
  3. What the change is. Specific scope. "Upgrade the lobby glazing" is vague. "Replace the four lobby storefront units with the 1" insulated low-E spec per the Sept 9 submittal" is not.
  4. What it costs. A number if you have one, a stated basis if you don't — time and materials, not-to-exceed, a pending quote from the sub.
  5. What it does to the schedule. This is the one people skip, and it's the one that costs the most later. If a change eats four days of float, say so in writing at the time — otherwise you own the delay.
  6. What happens next. Who's issuing the formal change order, and by when.

The same-day confirmation email

This is the whole method. Send it the day of the call, before you go home. It takes four minutes.

Subject: Confirming today's call — lobby glazing change

Dana,

Confirming what we discussed at 2:40pm today:

You approved the lobby glazing change to the 1" insulated low-E units per the Sept 9 submittal, at $18,400. We're proceeding Monday.

This pushes the storefront install four working days. I'll have a revised schedule to you Monday showing the impact to the Nov 3 TCO date, plus the overtime option we discussed to hold that date.

I'll issue CO-14 for signature tomorrow. If anything above doesn't match your understanding, let me know today.

— Mike

Three things make this work. It's specific enough to be unambiguous. It states the schedule impact, so silence can't later be read as the change being free of delay. And it closes with an invitation to correct the record, which means an unanswered email becomes meaningful rather than merely sent.

What happens when you don't

What goes wrongWhat it costs
The formal change order never gets signedYou've performed work with no executed authorization. Payment becomes a negotiation instead of an invoice.
The owner disputes the scope or the numberWithout a contemporaneous record, it's your memory against theirs — and theirs will favor them, usually sincerely.
The change caused a delay you never documentedThe delay gets attributed to you. Liquidated damages can follow.
Undocumented extras pile up over monthsAt closeout you're arguing about a dozen small items at once, which is the worst possible time and the weakest possible position.
A lien or claim becomes necessaryLien statutes are strict and deadline-driven. Vague or reconstructed records make an already technical process much harder.

Building the habit so it actually happens

Do it before you leave the truck. The confirmation that gets sent is the one written within an hour. The one you plan to write tonight doesn't get written.

Keep one running list of open items. Undocumented changes are rarely forgotten in the moment — they're forgotten three weeks later, when nobody remembers there was a change to document. A single list beats memory and beats scattered notes.

Use the same format every time. Consistency is what makes a stack of emails read as a business record rather than a pile of correspondence.

Capture the call itself where you can. A recording or a recap of the conversation is stronger than a summary written from memory — it's contemporaneous by definition. If you record calls, know the rules in your state first: twelve US states require every party to consent, and getting it wrong is criminal, not civil. We keep a plain-English guide to recording laws for exactly this.

What this doesn't fix

A same-day email is evidence, not authorization. It doesn't override a contract clause requiring signed change orders, it doesn't guarantee payment, and it doesn't substitute for following your contract's notice provisions — many contracts require written notice of a claim within a short window, sometimes as little as seven or fourteen days, and blowing that deadline can waive the claim no matter how well documented it is.

Read your notice clause. Know your number. Then document everything anyway.

Common questions

Is a verbal change order legally binding in construction?

It can be, depending on the state and the contract, but it is much harder to enforce than a written one. Most construction contracts require changes to be authorized in writing. Courts sometimes allow recovery for verbally authorized work under theories like waiver, course of dealing, or unjust enrichment — but each requires proving what was actually agreed, which is where contemporaneous documentation becomes decisive.

What should a change order confirmation email include?

Six things: who authorized the change, the date and time of the conversation, the specific scope, the cost or the basis for pricing it, the schedule impact, and who is issuing the formal change order and when. Close by asking the other party to correct anything that doesn't match their understanding.

How soon should I document a verbal change order?

The same day, ideally within an hour of the conversation. Same-day records are contemporaneous, which makes them significantly more credible than notes reconstructed later, and they still reflect what was actually said rather than what you remember.

Can I record a call with an owner to document a change order?

In most US states yes, because you are a party to the conversation. Twelve states require consent from everyone on the call, and violations there are criminal offenses rather than civil ones. Canada is one-party consent federally, with additional business obligations under PIPEDA. Check the rules for your state before recording.

What if the owner refuses to sign the change order after approving it verbally?

Your contemporaneous records become the core of your position. A same-day confirmation email that went unanswered, a recording or recap of the call, daily reports showing the work performed, and a consistent paper trail all support that the change was authorized. Follow your contract's notice and claim provisions carefully, and involve a construction attorney before the deadlines run.
