A cease and desist order is good for as long as the issuing authority says it is: a temporary restraining order typically expires within 14 days, a preliminary injunction lasts while the underlying lawsuit is pending, a permanent injunction has no built-in end date, and an FTC consent order generally runs 20 years. A cease and desist letter is different. It has no expiration at all, because it is not a legal order in the first place. It stays useful to the sender only as long as the legal claim behind it can still be filed in court.
Letter or Order: Which One Do You Have
The word “cease and desist” gets used for two very different documents, and the duration question has a different answer for each.
A cease and desist letter is a written demand sent by a person or their lawyer telling someone to stop an activity. It is not filed with any court, and on its own it has no legal force. It is essentially a formal warning that says stop or I will sue.
A cease and desist order is issued by a court or a government agency after a legal proceeding. It is binding, and violating it can trigger fines, contempt charges, or both.1Legal Information Institute. Cease and Desist Order The Federal Trade Commission, for example, issues cease and desist orders against companies engaged in unfair business practices, and those orders carry real penalties for noncompliance.2Office of the Law Revision Counsel. 15 USC 45 – Unfair Methods of Competition
If a private party or a law firm mailed it to you, it is a letter. If a judge signed it, or a federal agency issued it after a formal proceeding, it is an order.
How Long a Cease and Desist Letter Stays in Play
A cease and desist letter does not expire. No clock starts when it arrives, and there is no date after which the paper becomes invalid. What matters is the legal claim behind it, and that claim stays alive only as long as the relevant statute of limitations has not run out.
Most letters include a response deadline, usually somewhere between 7 and 14 days. That deadline is chosen by the sender, not required by any law. Missing it does not automatically start a lawsuit, but it does signal that you are not taking the matter seriously, which makes litigation more likely. The sender can still file suit weeks or months later, provided the statute of limitations for the claim has not expired.
How long a letter matters in practice comes down to whether the sender is willing to follow through. Some senders file within weeks. Others send letters as a bluff and never do anything else. The letter itself will not tell you which situation you are in.
How Long a Court-Issued Order Lasts
When a court issues an actual cease and desist order or injunction, the duration depends on the type of order. Three main varieties exist, and each has its own timeline.
- Temporary restraining order (TRO): An emergency measure issued to prevent immediate harm. A TRO typically expires within 14 days unless the court extends it for good cause.3Legal Information Institute. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders
- Preliminary injunction: Issued after a hearing where both sides argue. It stays in effect while the underlying lawsuit is pending, until the court issues a final ruling or modifies the injunction.
- Permanent injunction: Issued as part of a final judgment. It has no built-in expiration and remains enforceable indefinitely unless the court later modifies or dissolves it.
Violating any of these can result in contempt of court, which carries fines and possible jail time. That is the practical gap between a letter and an order: ignoring a letter may lead to a lawsuit, but ignoring a court order can lead to a cell.
How Long an Agency Order Lasts
Federal agencies including the FTC and SEC can issue their own cease and desist orders after administrative proceedings. These are binding and carry meaningful penalties.
FTC consent orders typically remain in force for 20 years from the date of issuance, with possible extension if a violation complaint is filed. Each day of noncompliance counts as a separate violation, and each violation can bring a civil penalty of up to $10,000.2Office of the Law Revision Counsel. 15 USC 45 – Unfair Methods of Competition FTC orders under Section 5 of the FTC Act become effective 60 days after service.4eCFR. 16 CFR 3.56 – Effective Date of Orders The FTC can also reopen and modify its orders when circumstances change.
In the housing finance context, temporary cease and desist orders under the Federal Housing Enterprises Financial Safety and Soundness Act remain in effect until the charges are dismissed or the temporary order is superseded by a final cease and desist order.5eCFR. 12 CFR 1209.6 – Temporary Cease and Desist Orders
The Statute of Limitations Behind the Letter
A letter does not expire, but the claim behind it does. Once the statute of limitations runs, the sender loses the ability to sue. That is the real answer to how long a letter is good for.
Copyright
A copyright holder must file suit within three years of when the infringement occurred or was discovered.6Copyright Claims Board. Frequently Asked Questions In Warner Chappell Music v. Nealy, the Supreme Court assumed without deciding that the discovery rule applies, so a copyright owner who did not know about the infringement could recover damages stretching back well beyond three years, provided the lawsuit is filed within three years of discovery.7Supreme Court of the United States. Warner Chappell Music Inc v Nealy (2024) A copyright owner who sends a letter and then sits on the claim risks losing damages for older infringement.
Patents
Patent owners cannot recover damages for infringement that occurred more than six years before the lawsuit was filed.8Office of the Law Revision Counsel. 35 USC 286 – Time Limitation on Damages The Supreme Court has also held that the defense of laches cannot bar claims brought within that six-year window, so a patent holder who sends a cease and desist letter still has the full six years to act.
Defamation
Defamation has some of the shortest limitations periods in American law. Most states allow only one to two years, with the full range running from six months to three years depending on the state and whether the claim involves spoken or written defamation. If a letter arrives near the end of that window, the sender’s leverage is limited.
Trademarks
Federal trademark law under the Lanham Act sets no specific statute of limitations. Courts instead apply the doctrine of laches, which looks at whether the trademark owner waited too long and whether that delay hurt the other party. A trademark holder who sends a letter and then does nothing for years may find a court unwilling to grant relief. Trademark owners who fail to police their marks can also weaken or lose their rights over time.
When Your Own Letter Has Teeth: Debt Collection
One scenario turns the usual analysis around. Under the Fair Debt Collection Practices Act, you can send a written notice to a debt collector demanding they stop contacting you, and the collector must comply.9Office of the Law Revision Counsel. 15 USC 1692c – Communication in Connection With Debt Collection After receiving your letter, the collector can only contact you to confirm they are stopping collection efforts or to notify you of a specific legal action, such as filing suit.
This is one of the few situations where a letter sent by an ordinary person, not a lawyer, creates an enforceable legal obligation. A collector who keeps calling after receiving written notice is violating federal law, and you can sue for damages and attorney’s fees.10Consumer Financial Protection Bureau. How Do I Get a Debt Collector to Stop Calling or Contacting Me The letter’s effect lasts indefinitely for that debt and that collector. Telling a collector to stop calling does not make the debt go away, though. The creditor can still sue you to collect what is owed.
What Can End a Cease and Desist Before It Would Otherwise Run
Several things can neutralize a letter or shut down an order early.
- The statute of limitations runs. Once the sender can no longer file suit, the letter is an empty threat.
- The underlying right disappears. A copyright expires, a patent lapses, a trademark is abandoned. With no right left, there is nothing to enforce.
- The sender abandons the claim. Years of inaction after a letter can lead a court to find the delay unreasonable and refuse relief.
- A court rules against the sender. If litigation ends with no finding of infringement or other violation, the cease and desist is dead.
- The parties settle. A negotiated agreement replaces the letter and sets new terms.
A court-issued order ends only when it expires by its own terms, when the issuing court dissolves or modifies it, or when an appellate court overturns it. There is no waiting one out the way an informal letter can sometimes be waited out.
