Letter Of Intent To Sue: Guidelines For Use (2026)

What Is a Letter of Intent to Sue?

A letter of intent to sue explains that your rights have been violated and that you intend to file a lawsuit against the recipient.

Sometimes, this letter is a last-ditch effort to settle a claim. For example, a letter may include a settlement demand that, if not met, will trigger the lawsuit. In other cases, the party is not interested in settlement and sends the notice letter simply to comply with the legal requirements of their claim.

Letter of Intent to Sue vs. Cease and Desist Letter

You follow similar steps to write a letter of intent to sue as you would to draft a cease and desist letter. The primary difference is that the recipient may avoid a lawsuit by stopping the wrongful actions described in the cease and desist letter.

By contrast, a letter of intent to sue usually states that the harm has been done and that the sender plans to sue. The letter may sometimes contain an offer to settle.

When to Send This Pre-Litigation Letter

A pre-lawsuit letter is not required in most cases. In these situations, you might send a letter to pressure the other party into a settlement.

However, letters are required in certain scenarios. Federal laws require debt collectors to send a letter that validates the debt within five days of contacting the debtor to collect the debt. 

However, a lawsuit pleading is not considered a “first contact” that requires debt validation. Thus, this letter is required when collecting a debt but not filing a lawsuit unless the debt collector contacts the debtor beforehand.

Many contracts require notice and an opportunity to cure the breach before filing a contract lawsuit.

Some states require plaintiffs to send a notice before suing the government. For instance, New York requires a Notice of Claim by anyone who intends to file a personal injury lawsuit against a city, county, school district, or other public corporation within 90 days of the injury.

A separate law allows an injured party to send a notice of claim or file a lawsuit within 90 days of an injury blamed on a state government agency. If the accident victim sends a notice of claim, the deadline to file a lawsuit is extended to two years.

The federal government also requires pre-suit notification for injury, death, or property loss. You can file a lawsuit seeking damages if the federal agency denies your claim or fails to settle within six months.

Laws That Require Notice Before You Sue

State laws may also require pre-litigation notice for certain legal claims, although this requirement varies. For example, the California Consumer Legal Remedies Act (CLRA) requires consumers harmed by deceptive trade practices to send a letter 30 days before starting a damages lawsuit.

Texas’s Deceptive Trade Practices Act (DTPA) requires a letter to be sent at least 60 days before commencing a damages lawsuit. The notice describes the specific complaint and the damages suffered.

States may also require pre-suit notice for medical malpractice lawsuits. Michigan’s medical malpractice law requires 182 days’ notice, while Florida requires a pre-suit investigation and 90 days’ notice.

Other states may have similar requirements. Skipping the notice requirement may result in case delays.

Key Elements to Include in the Letter

The main elements of a letter of intent to sue include:

• Sender's and recipient's names and addresses
• A description of the harm, including the date, place, and manner
• Legal grounds for the lawsuit
• Damages demanded with category
• Response deadline
• Copies of supporting documents
• An offer to settle

Include any statutorily required information. For example, a Texas DTPA notice must list attorney’s fees you intend to claim.

Step-by-Step Guide to Drafting the Letter

The process for drafting letters of intent usually follows these steps:

1. Consult a lawyer or perform legal research to determine the grounds for a lawsuit.
2. Write a description of the legal claim, including its factual basis and legal grounds.
3. State your intent to exercise your legal rights by filing a lawsuit.
4. Add an offer to settle your case and a response deadline, if you are open to settlement.

Pre-suit settlement letters are inadmissible in federal and many state courts to prove or disprove the validity or value of a claim.

Best Practices for Delivering the Letter and Next Steps if Ignored

You should send the letter with delivery confirmation, particularly when the letter is legally required. For example, California’s CLRA requires mailing by certified or registered mail with return receipt requested.

Keep the receipt and a copy of the letter. If the other party ignores the letter despite proof that they received it, you can follow through by filing a lawsuit.

A pre-suit letter does not pause the statute of limitations unless the law states that it does. Make note of the statute of limitations deadline to avoid missing it.
