How Long Do You Have to Respond to a Cease and Desist Letter?
There's no legal deadline to respond to a cease and desist letter, because it isn't a court filing. The deadline you see in the letter — often somewhere between 10 and 30 days — is set by the sender, not by law.
But the real question behind this one is usually bigger: do I even have to respond, and what happens if I don't? Here's the full picture.
Key takeaways
- Any deadline in the letter is set by the sender, not by statute — commonly 10 to 30 days.
- You are not legally required to respond at all, because the letter isn't a court order.
- Missing the deadline triggers no automatic penalty, but it raises the odds the sender escalates.
The deadline is set by the sender
Cease and desist letters usually state a response window — frequently 10 to 30 days, and sometimes as short as 5 to 10 business days. That number comes from whoever wrote the letter. There is no statutory deadline, because no court is involved yet.
Do you have to respond at all?
Legally, no. The letter is a demand, not a court order, so you're not obligated to reply. But 'not required' isn't the same as 'wise to ignore.'
Three things people conflate
- The deadline in the letter is the sender's, not a legal one.
- You're not legally obligated to respond.
- Ignoring it is still risky — it often leads to a lawsuit or injunction.
What happens if you miss the deadline
Nothing happens automatically — there's no fine or penalty just for letting the date pass. What changes is the sender's likely next move: missing the deadline makes escalation more probable, whether that's a follow-up, a complaint, or a lawsuit.
If you need more time to evaluate a serious claim, it's often reasonable to ask the sender for an extension in writing rather than going silent.
