Massachusetts Small Claims Demand Letter: When You Need One Before Filing
Two Types of Demand Letters
Massachusetts treats demand letters differently depending on the type of claim. For most disputes, a written demand is good practice but not legally required. For consumer protection claims under Chapter 93A, a specific 30-day demand letter is mandatory — skip it and you lose the right to double or triple damages under that statute.
The Mandatory Chapter 93A Demand Letter
M.G.L. c. 93A, § 9 requires consumers to send a formal demand letter to the business at least 30 full days before filing a lawsuit. This applies whenever you're claiming a business engaged in unfair or deceptive practices — which covers a wide range of small claims situations:
- A landlord who failed to handle your security deposit properly under M.G.L. c. 186, § 15B
- A contractor who took payment and didn't perform the work as described
- A business that sold a defective product and refused a refund
- A company that misrepresented its services
The 93A demand letter must include three things:
- A description of the unfair or deceptive act — what exactly the business did or failed to do
- The specific injury you suffered — how their conduct harmed you
- The exact dollar amount of your loss — not a range, but a specific number
Although certified mail, return receipt requested, is not required by law, it is recommended as proof of delivery. Keep the postal receipt and the green card (or tracking confirmation) for your records.
What Happens During the 30-Day Window
The business has 30 days after the letter is mailed or delivered to respond. Three things can happen:
They offer a reasonable settlement. If the offer adequately compensates your loss, accepting it may end the dispute. If you reject a reasonable offer and proceed to court, the court may reduce your recovery to the amount offered.
They respond with a partial offer or denial. Document everything in writing. Their response (or lack thereof) becomes evidence at the hearing.
They don't respond at all. After 30 days of silence, you've satisfied the pre-suit requirement and can file your small claims case with the right to seek statutory multiple damages.

Why the 93A Letter Matters for Damages
Without a valid 93A demand letter, you can still sue for your actual damages — the money you're owed. But you forfeit the statutory multiplier. Under Chapter 93A, if the business's conduct was willful or knowing, the court can award double or triple your actual damages plus reasonable attorney's fees.
On a $3,000 security deposit claim, the difference between 1x and 3x is $6,000. The 30-day wait is worth it.
Informal Demand Letters for Other Claims
For simple contract disputes — an unpaid invoice, a loan not repaid, a deposit not returned outside of a 93A context — a written demand isn't legally required. But it accomplishes two things:
It demonstrates good faith. The magistrate at your hearing will look more favorably on a plaintiff who tried to resolve the dispute before filing suit.
It creates a paper trail. The defendant's response (or silence) is evidence. If they acknowledged the debt in writing, that response strengthens your case considerably.
An informal demand letter should state:
- What the defendant owes and why
- The specific amount
- A reasonable deadline for payment (14–30 days)
- That you intend to file a small claims case if the matter isn't resolved
Certified mail provides proof of delivery; regular mail does not provide the same delivery record.
Timing the Letter With Your Filing
For 93A claims, allow the business 30 days after the letter is mailed or delivered to respond before filing. If you file before the 30 days expire, the court can dismiss the 93A portion of your claim.
If your statute of limitations is running short — say, less than 60 days remaining — send the demand letter immediately and mark your calendar for the earliest possible filing date.
