Contract termination letter template: free in Word, or sign it online
Reviewed in October 2026
A contract termination letter is a written notice that ends an agreement with a supplier, client or contractor. It names the contract, the clause that allows ending it, the end date and what each side still owes. Sending it the right way protects you from claims later.
Ten documents free, no card. Signed by the party ending the contract and the other party, to confirm receipt.

How it gets signed
1Choose “Use this template”, fill in the fields and read the full contract termination letter once more.
2Send it by WhatsApp or email. The other party opens the link on their phone without an account.
3They tap the brown bar at the bottom that says “Sign as …” and draw their signature with a finger.
4Everyone gets the signed PDF with its signature certificate. Anyone can check it at signsolu.com/verificar.
Before signing, each signer agrees to sign electronically. The screen links to the electronic signature disclosure the ESIGN Act asks for.
The receipt signature is optional. The certificate already shows when the notice was sent and opened. If your contract asks for notice by mail or to a specific address, send it that way too.
Your first ten documents are free and need no card.

What the law says
How you can end a contract depends on the contract itself. Read the termination and notice clauses before you write. They set the notice period, the reasons allowed and how notice must be delivered.
Ending a contract without a right to do so can be a breach. If you rely on the other side’s breach, show that you gave notice and the time to fix it the contract requires.
The ESIGN Act treats an electronic notice as valid when the contract allows notice by email. The certificate gives you a dated record of delivery.
Read the contract first
Notice period. Count the days and pick an end date that respects them.
Allowed reasons. Some contracts allow ending only for breach.
How to deliver. Email, certified mail or a named address.
What survives. Confidentiality and payment duties often continue.
Ending for convenience, breach or non-renewal
Convenience means you end it without blaming anyone, as the contract allows. Breach means the other side failed and did not fix it. Non-renewal means you let the term expire.
Pick one option and delete the others. Mixing reasons weakens the letter.
A worked example
Harbor Dental wants a new cleaning company. Its agreement with CleanPro allows ending for convenience with 30 days of notice by email.
The office manager sends this letter on October 21 with November 20 as the end date. CleanPro signs to confirm receipt the same day. The final invoice and the keys arrive on time.
Keep the tone calm
A termination letter may be read by a judge one day. Stick to facts, dates and clause numbers. Leave out frustration and blame.
Employees are different
This letter is for business contracts. To end a job, use the employee termination letter, which covers final pay and benefits.
Proof of delivery
Disputes often turn on when notice arrived. SignSolú records when the letter was sent, opened and signed. Keep that certificate with the original contract.
Notice periods that cause trouble
Business days or calendar days. Read the clause carefully and count the right way.
Notice from receipt or from sending. Many contracts count from receipt, so send early.
Auto-renewal windows. Miss the window and the contract renews for another full term.
Put a reminder in your calendar sixty days before each renewal date. That gives time to decide and send this letter.
After the contract ends
Check the final invoice against the work delivered. Pay or dispute it in writing within the time the contract sets.
Ask for the written confirmation that your information was returned or destroyed. Remove the other party’s access to your systems and buildings on the end date.
Sample lines for common situations
Supplier: “Please deliver the last order of November 10 and send the final invoice by November 25.”
Software subscription: “Please cancel automatic renewal and confirm that our data will be exported to us by the end date.”
Contractor: “Please complete the work in progress through November 15 and invoice it separately.”
Client: “We will finish the current month’s work and stop all services on the end date.”
Breach: “Our notice of September 30 described the missed deliveries. The 15-day cure period ended without a fix.”
Add the lines that apply to clause 4. Each one tells the other party exactly what happens next.
Checklist before you send the notice
1You read the termination and notice clauses again.
2The end date respects the full notice period.
3You chose one reason and deleted the others.
4You know how the contract asks for notice to be delivered.
5You have a plan to replace the service or the client.
Then send the letter and save the signed PDF and its certificate with the original contract.
If the other party asks to talk before the end date, you can still meet. The notice stands unless both sides sign a new agreement.
Is a termination letter signed online legally binding?
Yes. The ESIGN Act gives an electronic signature the same legal effect as a handwritten one. The signed PDF and its certificate show who signed the termination letter, when and from which device.
Does the other party need a SignSolú account to sign?
No. They open the link on their phone and sign with the brown bar at the bottom of the screen.
Can I download the contract termination letter in Word?
Yes. “Download in Word” gives you the full contract termination letter with no email and no account. You can print it or edit it and sign it here later.
Can I end a contract by email?
Yes, if the contract allows notice by email. If it asks for mail, send a copy by mail too.
What if the other party does not sign the receipt?
The notice still counts if it was delivered as the contract requires. The certificate shows delivery.
Can I take back a termination notice?
Only if the other party agrees in writing. Sign a short agreement that keeps the contract in force.
Should I send the letter by certified mail too?
If the contract asks for mail delivery, yes. Send the signed PDF by email and a printed copy by certified mail.
