Auto Repair Authorization Form: Template and Rules

A fill-in auto repair authorization form, the fields state laws ask for, and how to record phone, text and e-signature approvals and approve added work.

An auto repair authorization form is the customer's written yes to specific work at a specific price, and it's the document that settles most billing disputes before they start. In several states it's also a legal requirement: California, New Jersey, Massachusetts and Pennsylvania all tie your right to charge to an authorization you can show.

More on this topic: Auto repair laws and compliance, every guide in one place.

Below: what the form should include and why, a full template you can copy, how to record approvals by phone, text and e-signature, and how to approve added work without losing a day. State examples come from the regulations themselves, read in October 2026.

The short answer

An auto repair authorization form, in short: a signed record of the customer, vehicle, odometer reading, the specific work and its price, any estimate or diagnostic fee, a not-to-exceed amount, parts preference and return request. Record phone or text approvals with date, time, both names, the exact amount and the number used.

Key takeaways

Authorize specific work at a specific price; "fix whatever it needs" protects nobody.
Put the odometer reading, the requested work and any estimate or diagnostic charge on the form before work starts.
Record phone and text approvals with the date, time, who approved, who took it, the work and amount, and the number or address used.
Approve added work on a revised estimate with a new total before you start it.
Add your state's required wording (Florida's disclosure box, Washington's notice, Ohio's form) word for word.

What is an auto repair authorization form?

It's the customer's signed approval of specific repairs at a stated price, usually on the estimate or repair order itself. It does three jobs: it shows the customer agreed before you started, it sets the most you can charge without asking again, and it records choices such as returned parts and who else may approve work. New Jersey treats paid work without "Specific written authorization from the customer, signed by the customer" stating the repair and odometer reading as a deceptive practice; Massachusetts lets you charge only with a signed authorization listing the repairs and total price, posted prices, prior notice or a signed waiver.

What should an auto repair authorization form include?

Include who, what car, what work, what price and what the customer chose. Each field and why it's there:

Field	Why it matters	State example
Shop name, address, phone and registration number	Identifies who is responsible; some states require the number	Florida estimate; California invoice
Customer name, phone, address	Who authorized and how to reach them	Florida 559.905
Year, make, model, VIN or plate, odometer reading	Ties the approval to one vehicle and mileage	New Jersey requires the odometer reading; Florida bans a work order without it
The problem or the work requested	Defines what was authorized	Pennsylvania work record; Florida 559.920
Itemized estimate: parts, labor, fees, total	Sets the price the customer agreed to	California, New Jersey, Washington
Estimate or diagnostic charge	Several states require disclosure first	Massachusetts, Florida, Pennsylvania, New Jersey
Not-to-exceed amount or estimate choice	The ceiling before you call again	Florida, Washington, Ohio, Pennsylvania
Replaced parts: return, inspect or discard	Most estimate laws give this right	California, Florida, Massachusetts, New York
Person allowed to approve added work	Saves a day when the owner can't be reached	California designation; Florida estimate
Storage charges after notice of completion	Disclosure before authorization	Florida, Massachusetts, Pennsylvania
Signature, date and time, or the recorded approval	The proof	California, Massachusetts, Washington

What does a complete authorization form look like?

Here's a template you can paste into your estimate or repair order. Replace the bracketed parts with your own details and add your state's required notice where marked.

Repair authorization template

[Shop name], [address], [phone]. State registration no. [number, if your state issues one]. Repair order no. [number]
Customer: [name], [phone], [email], [address]
Vehicle: [year] [make] [model], VIN [VIN], plate [plate], odometer in [miles]
Customer's concern or requested work: [in the customer's words]
Estimate: [each job on its own line with parts (new, used, rebuilt or reconditioned, OEM or aftermarket) and labor priced], fees [itemized], estimated total [amount] plus tax where it applies
Estimate or diagnostic charge: [amount, or how it's calculated], which [is / is not] credited toward the repair
Price limit: We will not exceed [amount] without your approval. [Your state's required estimate notice or choice form goes here, word for word.]
Replaced parts: [ ] Return them to me [ ] I want to inspect them [ ] Dispose of them. Cores and warranty returns can be inspected but not kept.
Other person who may approve added work: [name, phone] (optional)
Storage: [amount] per day, starting [number] days after we tell you the vehicle is ready.
Warranty: [months and miles, parts and labor]
I authorize the work listed above at the prices shown. Signature [ ] Date [ ] Time [ ]
Approved by phone or text instead: date [ ], time [ ], name of person approving [ ], number or email used [ ], work and amount approved [ ], taken by [employee]

Give the customer a copy of the signed form at signing; California, Massachusetts and Florida all require copies of what the customer signs. The storage and warranty terms are your choices; see our guides on the warranty policy and storage fees.

How do you record phone, text and e-signature approvals?

Record them as carefully as a signature, because the record is your only proof. States that spell it out ask for nearly the same fields:

State	Fields to record
California	Oral: date, time, name, phone number called. Electronic: date, time, name, email or text number; keep the messages with the job.
Massachusetts	Date and time, employee, person authorizing, the exact authorization, number called if you called
Pennsylvania	Date and time, employee, person authorizing, the exact authorization, number called if you called
Washington	Date and time, employee name or ID, name and phone number of the person authorizing

A text approval works the same way: save the thread, note the time and number, and attach it to the repair order. For e-signatures, the federal ESIGN Act says a signature or record "may not be denied legal effect, validity, or enforceability solely because it is in electronic form". If a law requires you to give the customer something in writing and you send it electronically instead, ESIGN adds consumer-consent steps, so keep paper copies available. For call wording, see our phone script.

How do you get authorization for additional work?

Write a revised estimate with the added work and the new total, contact the customer, and record their approval before you start. A short script:

"Hi Ms. Rivera, it's Sam at [shop]. While replacing the front pads we found the right caliper is sticking. Replacing it is $186.40 with parts and labor, which brings your total from $412.80 to $599.20. Do you want us to go ahead? ... Great, I've noted your approval at 2:14 pm. We'll text you when it's ready."

The amounts are an example. How much room you have before you must call depends on the state: none in California, New Jersey or New York, $10 in Massachusetts, $10 or 10% capped at $50 in Florida, and 10% in Ohio, Maryland and Washington. Our estimate laws by state guide has the full table. California also requires the revised work order and recorded consent on the invoice, or the customer's signed acknowledgment of the oral approval at pickup.

If the owner is hard to reach, ask at drop-off for a second person who may approve added work. California requires that designation at the first authorization, on a form with a set title; Florida's estimate has a line for it.

Which state wording should you add to the form?

Add any notice your state prescribes, copied from the law, not paraphrased:

Florida: the boxed disclosure over $150, headed "PLEASE READ CAREFULLY, CHECK ONE OF THE STATEMENTS BELOW, AND SIGN", with three options. See our Florida Motor Vehicle Repair Act guide.
Washington: the notice that begins "YOU ARE ENTITLED TO A WRITTEN PRICE ESTIMATE FOR THE REPAIRS YOU HAVE AUTHORIZED", with three choices.
Ohio: a form where the customer initials written, oral or no estimate.
Massachusetts: any waiver signed separately, beginning "I understand that I have the right to know before authorizing any repairs what the repairs to my car will be".
California: the designation form title and, at pickup after a phone approval, the acknowledgment "I acknowledge notice and oral approval of an increase in the original estimated price." See our California BAR rules guide.

This isn't legal advice: rules change and cities or counties can add their own, so check the current text or ask a lawyer or your state association before you change your forms.

Frequently asked questions

Do I need a signed authorization before repairing a car?

In several states, yes. New Jersey requires signed written authorization stating the repair and odometer reading; California requires recorded authorization on the estimate; Massachusetts allows charges only with a signed authorization, posted prices, prior notice or a signed waiver. Elsewhere it's still your best proof.

Is a verbal authorization for car repair legal?

Usually, if you record it. California, Massachusetts, Pennsylvania and Washington list the details: date, time, who approved, who took it, the exact work or amount, and the number called.

Can customers approve repairs by text?

California explicitly accepts electronic authorization if you record the date, time, name and the text number or email, and keep the messages with the job. Check your state's rule.

What if a customer drops off a car after hours?

A note left with the car isn't authorization in California. Write the estimate, reach the customer by phone, text or email, and record the approval. Florida treats after-hours drop-off as a partial waiver but still requires contact after diagnosis.

Should the authorization form include a price limit?

Yes. A not-to-exceed amount tells the customer, and your technicians, when you must call before going further. Florida, Washington and Pennsylvania build that option into their required forms.

Where BayRobin fits

In BayRobin, the customer approves or declines each service on one link, phone approvals are recorded with your name, and approved work becomes the invoice, sent by text with a pay link. Your state may ask for more than that record (the time, the number called, its own notice), so check it against your state's wording. See inspections, estimates and invoices. BayRobin is free until your first 10 booked jobs, no card up front. Start free or see pricing.
