A cease and desist letter in Massachusetts is a written demand that someone stop conduct you believe violates your legal rights. It is not a court order, and the recipient has no obligation to reply. What it does is create a documented record that Massachusetts courts take seriously, and under the state’s consumer protection statute, sending one is a legal prerequisite to filing certain lawsuits.
Most letters in Massachusetts arise from trademark or copyright infringement, breach of a non-compete or licensing agreement, harassment, or unfair and deceptive business practices under Chapter 93A. The strategic purpose is the same in each case: give the other side a chance to stop before you spend money on litigation, and show a judge later that you tried.
When Massachusetts Law Requires a Demand Letter
Chapter 93A is the reason cease and desist practice in Massachusetts looks different from other states. Section 2 of the statute declares unfair or deceptive business practices unlawful without listing what qualifies; courts decide case by case, guided by federal trade regulation standards.1General Court of Massachusetts. Massachusetts General Laws Chapter 93A, Section 2
Consumer Claims Under Section 9
If you are a consumer suing a business under Chapter 93A, the demand letter is mandatory. Section 9 requires that at least 30 days before filing suit, you mail or deliver a written demand identifying who you are, describing the unfair or deceptive practice, and explaining the injury you suffered.2General Court of Massachusetts. Massachusetts General Laws Chapter 93A, Section 9 Skip it and your case will be dismissed.
The 30-day window is also a settlement window. If the business responds with a reasonable written settlement offer during those 30 days and you reject it, the court can cap your recovery at the amount that was offered. If you win and the court finds the violation was willful or knowing, damages can be doubled or tripled and you recover attorney’s fees.2General Court of Massachusetts. Massachusetts General Laws Chapter 93A, Section 9
Business-to-Business Claims Under Section 11
When one business sues another under Chapter 93A, Section 11 controls, and it does not require a pre-suit demand letter. Sending one is still worthwhile. A court that finds a willful or knowing violation must award between two and three times actual damages, plus attorney’s fees.3General Court of Massachusetts. Massachusetts General Laws Chapter 93A, Section 11 A business defendant can limit exposure by filing a written settlement offer with its answer; if the court later decides the offer was reasonable, recovery is capped at single damages.
For every other type of claim — trademark, copyright, contract, harassment — no Massachusetts statute forces you to send a letter first. It is still the standard opening move because judges expect it and injunctions are easier to obtain when you can show you gave notice.
What to Put in the Letter
You do not need a lawyer to send a cease and desist letter in Massachusetts. Anyone can write one. A letter on an attorney’s letterhead tends to carry more weight because it signals the sender has already committed to legal counsel.
An effective letter covers four things:
- Who you are and the legal right at stake — a trademark registration, a copyright, a specific contract provision, or a consumer protection claim.
- The specific conduct you want stopped, described in enough detail that the recipient cannot claim confusion about what they are accused of doing.
- Why that conduct violates your rights, with reference to the applicable Massachusetts statute or common law principle.
- What you want: stop the activity, destroy infringing materials, pay damages, or some combination.
For a 93A demand letter, Section 9 sets the floor: your identity, a description of the unfair or deceptive practice, and the injury you suffered.2General Court of Massachusetts. Massachusetts General Laws Chapter 93A, Section 9 Vague descriptions weaken the letter and can undermine your case later. Be specific about what happened and what it cost you.
Most letters set a response deadline, commonly 10 to 30 days. No Massachusetts statute mandates a particular window, and recipients have no obligation to respond at all. A deadline creates urgency and gives a judge a reasonable timeline to look at. For 93A consumer claims, the 30-day statutory waiting period effectively sets the floor.
How to Send It
Delivery matters more than most senders realize. Certified mail with return receipt requested is the standard because it produces proof that you sent the letter and documentation of whether it was received, refused, or unclaimed. If the recipient later claims they never got it, the postal tracking records and signed return receipt card become evidence. Refused delivery still counts; USPS tracking documents the attempt, which courts generally treat as sufficient notice.
Email is faster and creates its own record, but it is easier for a recipient to claim they never saw it. For anything that might land in court, send a hard copy by certified mail regardless of what you also send electronically.
What Happens After You Send One
Compliance is the best outcome. The recipient stops the activity and either acknowledges the violation or opens a conversation about resolution. Many trademark and copyright disputes end here through licensing agreements or a simple agreement to stop.
Silence is also common. Recipients ignore cease and desist letters when they believe the claims lack merit or when they doubt the sender will follow through. Ignoring the letter is not itself illegal, but it forfeits any chance of a favorable pre-suit settlement.
If the recipient does not comply, the next step is filing suit. Massachusetts courts can issue a temporary restraining order to halt infringing activity immediately, followed by a preliminary injunction that stays in place while the case proceeds. A preliminary injunction generally requires showing likelihood of success on the merits, irreparable harm without the injunction, and a favorable balance of harms. The cease and desist letter becomes evidence that you acted diligently and gave the other side a chance to resolve things.
Massachusetts Trial Courts also offer court-connected alternative dispute resolution in every department, including mediation and arbitration.4Mass.gov.

The Anti-SLAPP Trap Senders Miss
Massachusetts has an anti-SLAPP statute (Chapter 231, Section 59H) that protects people exercising their right to petition government. Petitioning activity is defined broadly: statements to government bodies, statements connected to issues under government review, and statements encouraging public participation in government proceedings.6General Court of Massachusetts. Massachusetts General Laws Chapter 231, Section 59H
Here is where senders get caught. If you send a cease and desist letter threatening to sue someone for filing a complaint with a state agency or making public statements about your business connected to a government investigation, and you follow through, the defendant can bring a special motion to dismiss under Section 59H. The court must grant that motion unless you prove two things: that the defendant’s petitioning activity had no reasonable factual support or legal basis, and that it caused you actual injury.6General Court of Massachusetts. Massachusetts General Laws Chapter 231, Section 59H That is a heavy burden.
If the court grants the motion, you pay the other side’s attorney’s fees and costs, including fees for the motion itself and related discovery. All discovery is automatically stayed while the motion is pending, freezing your case. The motion can be filed within 60 days of being served with the complaint, or later if the court allows.6General Court of Massachusetts. Massachusetts General Laws Chapter 231, Section 59H
Before sending a letter that targets someone’s statements to or about government bodies, evaluate whether the anti-SLAPP statute applies. Threatening litigation over protected petitioning activity can cost you more than whatever you were trying to stop.
Responding to a Letter
If you receive a cease and desist letter, doing nothing is sometimes the riskiest option. You have several better paths.
Test the Legal Basis
Start with whether the sender actually holds the rights they claim. In a trademark dispute, that means checking whether their mark is registered, whether it has priority, and whether your use creates a genuine likelihood of confusion. In a contract dispute, review the specific provision cited and whether the sender’s interpretation holds up. A surprising number of letters overstate the sender’s position or misidentify the applicable law.
Negotiate
A licensing agreement can let you continue using a mark or work in exchange for payment. A modified business practice can eliminate the alleged infringement without shutting down a product line. If the letter invokes Chapter 93A and you are a business, consider responding with a written settlement offer; under Section 11, filing a reasonable offer with your answer can cap the other side’s recovery at single damages.3General Court of Massachusetts. Massachusetts General Laws Chapter 93A, Section 11
Assert Defenses
Fair use is a recognized defense in copyright disputes. Laches — unreasonable delay in asserting rights — can limit or bar recovery if the sender waited years while you built your business on their silence. For 93A claims, you can argue the conduct was neither unfair nor deceptive, or that it did not occur primarily and substantially within Massachusetts.7Mass.gov. The Massachusetts Consumer Protection Law If the sender’s claims target petitioning activity, the anti-SLAPP statute is a procedural weapon.
Timing and Statutes of Limitations
The strength of a cease and desist letter depends partly on whether the sender can still file suit. For breach of a contract for the sale of goods, Massachusetts imposes a four-year statute of limitations from when the breach occurred.8General Court of Massachusetts. Massachusetts General Laws Chapter 106, Article 2, Section 2-725 Other contract claims follow a six-year general limitations period. Federal trademark claims have no express statute of limitations but are governed by the equitable doctrine of laches. Chapter 93A claims generally must be filed within four years.
Delay weakens the sender’s position. A letter sent five years after the conduct began invites a laches defense and undercuts any claim that the injury is urgent enough for an injunction. From the recipient’s side, a letter about old conduct may be toothless if the filing window has closed.
