You designed the logo. Built the site. Shot the photos. Delivered the files. Then the final invoice went unpaid, and now you can see your work live on their site, their packaging, their Instagram. They stiffed you and they are using the work anyway. A cease and desist letter, tied to the copyright you still own, is the fastest way to turn that situation around.
You Still Own the Copyright Until You Get Paid
Under U.S. copyright law, creative work is owned by the person who made it the moment it is fixed in a tangible form. Ownership only transfers to the client if you signed a written assignment or a work-for-hire agreement that meets the statute's requirements. Most freelance invoices and email agreements do neither.
If your contract says something like "rights transfer upon full payment," the client using the work without paying is infringing your copyright. That is a stronger position than a plain unpaid invoice, and it opens up a different set of tools, including the demand letters covered in our cease and desist guide for creative work.
If you have no written contract at all, you likely still own the copyright, but you should assume the client will argue implied license. The letter needs to address that head-on.
When a Cease and Desist Fits Better Than a Demand
A plain demand letter asks for money. A cease and desist letter tells them to stop using the work and pay for it, or take it down. Use the cease and desist framing when:
- The client is actively using your work (website, ads, product, packaging, social)
- You can screenshot or point to specific uses with URLs and dates
- Your contract ties rights transfer to full payment, or there is no contract
- The invoice is more than 30 days past due with no good-faith response
If the client has not published the work yet, a standard demand letter for the unpaid invoice is usually the right first move. Save the cease and desist for when the infringement is happening in the open.
What to Put in the Letter
The letter has to do three jobs at once: identify the work, prove you own it, and give the client a clean choice between paying and pulling the work down.
- Your full name, business name, and contact information
- The client's legal name (the entity on the contract, not just a brand)
- A description of the specific work: files delivered, dates, project name
- Where the infringement is happening: URLs, screenshots, product SKUs, dates observed
- The unpaid invoice number, amount, original due date, and days past due
- A statement that you retain copyright because payment was never received
- Two clear options: pay the invoice in full by a deadline, or remove all uses of the work by the same deadline
- A 10 to 14 day deadline
- A statement that continued unauthorized use after the deadline will be treated as willful infringement
Attach the invoice as a PDF. Attach screenshots of the infringing uses with visible dates and URLs. Keep everything in one folder for later.
The Copyright Language That Does the Work
You do not need to sound like a lawyer. You do need to name the right thing. A short paragraph like this belongs in the letter:
The photographs delivered on March 4, 2026 remain my sole property under 17 U.S.C. § 102. No license, express or implied, has been granted for their use. The invoice for this work (INV-118, $2,400) remains unpaid 47 days past its due date. Your continued display of these images on [URL] constitutes copyright infringement. Payment in full by April 30, 2026 will resolve this matter and convey the license described in our agreement. Absent payment, all use of the work must cease by the same date.
Registered work carries stronger remedies (statutory damages and attorney's fees under 17 U.S.C. § 504-505). If you registered the work with the U.S. Copyright Office before the infringement started, say so in the letter. If you did not, do not bluff about statutory damages: your remedy is your actual invoice and any provable losses.
How to Send It So It Sticks
Send the letter by email and by certified mail with return receipt to the client's business address. The email creates speed; the certified copy creates proof of delivery for court.
If the client uses a hosted platform (Shopify, Squarespace, YouTube, Meta), you can also file a DMCA takedown notice with the host. That is separate from the cease and desist and should be considered a second track, not a replacement. Use the takedown when the client ignores the deadline, not before.
Keep every reply. Do not negotiate over the phone. If they call, tell them you will respond in writing.
What to Do When the Deadline Passes
Most clients pay or pull the work within a week of receiving a cease and desist tied to a real copyright claim. If yours does not, you have two workable paths:
- File in small claims court for the unpaid invoice amount, using the letter and screenshots as evidence of the debt and the ongoing use
- File DMCA takedowns with every platform hosting the work, then file in small claims for the invoice
Federal copyright infringement suits are a separate world (higher stakes, higher cost, and they generally require registration). For invoice-sized amounts, small claims combined with takedowns is the faster route. Before you file, review the final demand step so the court sees a clean escalation trail.
Getting the Letter Written Without Guessing
The hardest part of this letter is the tone: firm enough to move the client, precise enough about the copyright claim to hold up if you end up in front of a judge, and free of the emotional language that always creeps in when you have been ripped off.
PaperHammer drafts the three escalating versions (polite, firm, final) with the copyright framing built in and the small claims limit for your state referenced in the final version. You fill in the invoice details, the URLs where your work is being used, and the deadline you want, and download the PDFs in about five minutes. Review and edit before you send.
