When Is a Letter of Intent to Sue Needed?

This kind of letter goes out before a case is filed in court. It puts your complaint and your offer to settle in writing and gives the other side a chance to fix the problem or reach an agreement. Here is when it comes into play.

A plaintiff may be required to send the defendant a pre-suit letter as a condition to filing a lawsuit with the court under certain conditions, for instance:

  • Under the terms of an agreement
  • For suits brought under the Clean Water Act
  • Where the answering party is a governmental body
  • In medical malpractice cases
  • For lawsuits brought under state consumer protection law

In situations where a pre-suit letter is required, the plaintiff failing to provide the letter to the answering party might be dismissed from the lawsuit.

This is why for the plaintiff, it is important to check whether there is a requirement for a letter of intent to sue before starting judicial proceedings, while the answerer should check whether or not it is required if they haven’t got it. If the document is required, a defendant who failed to get it might make a motion for dismissal.

Keep the tone calm and factual, and avoid legal jargon. A short letter that says what happened and what you want is easier for the other side to answer.

What Should Be Included in a Notice of Intent to Sue?

Federal or state laws might not give clear instructions on what content of a pre-suit form should be. If the governing law is absent, the minimum requirements to a pre-suit letter are to include:

  • A detailed description of the plaintiff’s claims that constitute the basis for the contemplated legal action
  • Identification of all the prospective defendants and other parties who have the right to get the notice of intent to sue.
  • Statement of the relief the plaintiff seeks.
  • The period for the defendant to remedy the violation and/or settle the lawsuit outside of court.

A strong letter also says what the other side did wrong and offers a clear way to settle, such as fixing the problem or paying a fixed amount in damages.

It is important to convey the demand in the letter in a clear and concise manner and try to highlight it so that it doesn’t get lost in the details of the dispute. Another thing to remember is that the language should be without complicated law terms as the letter might be read by both lawyer and non-lawyer.

Please note that the notice should be sent by a reliable method of delivery. Registered mail is considered the safest option. Email might be used as well if it is possible to prove that the prospective defendant received it.

Another surefire way to give a letter is to deliver it in person. Then, the signature of the person or the presence of a witness will be needed.

Keep a copy of the letter and proof of how you sent it, such as a mailing receipt. You may need it later to show that the other side got it.

How to Fill Out a Letter of Intent to Sue

A letter of intent to sue is usually a single-page letter. It should be written in a respectful manner and include only important details – the illegal activity, actions that can help settle the dispute, and the ways to cover damage to avoid the lawsuit.

  1. Your details and the date. Start with your name, address, telephone number and email address. Add the date below it, then the name and address of the person or company you are writing to.
  2. The statement. Say that this is a formal notice. State that you plan to initiate legal action in court against the other party because of the problem you describe.
  3. The parties. Name both sides of the possible case, so it is clear who is writing and who is receiving the letter.
  4. The settlement offer. Explain how the other party can avoid court, for example by fixing the problem or paying a fixed amount. If a neighbor damaged the fence at your home, you might ask for payment to cover the cost. Pick a clear number of days for the reply and count them with our deadline calculator. End with a polite request, such as “Please contact me as soon as possible to resolve this matter.”
  5. Governing law. The plaintiff should state what law will be considered governing. The sample below does this in one sentence near the end.
  6. Closing. End with “Sincerely,” followed by your name and signature. If an attorney writes the letter for you, add their name and signature.

Read your draft once more and check that names, dates and amounts match your records. The sample below shows how the six parts fit together.

Sugar Land, TX 77479

RE: Notice of intent to file a lawsuit

Dear management of M&B company,

This letter serves as formal notice of intent to file a lawsuit against you because I believe that I was fired without cause. I have been working at the company for a year, and my last performance report, dated March 3, 2021, has received a positive review. But shortly after, I was asked to leave my job position without any reasonable explanation.

I desire relief in the form of compensation for immaterial damages in the amount of $10,000. This offer to settle this matter and avoid a lawsuit is valid for 14 business days after this letter’s date. If I did not receive a favorable response in 14 business days, I will promptly begin a lawsuit.

The letter of intent to sue is governed by the laws of the state of Texas.

Sincerely,
Mara Shean

Frequently Asked Questions

Here are short answers to common questions about writing and sending this kind of letter. If you want to start right away, select Create My Document at the top of this page and build a template online.

What is a letter of intent to sue?

It is a written notice that tells a person or company you plan to sue. It describes the problem, says what you want and gives the other side a chance to settle before the dispute goes to court.

What should I include in a letter of intent?

Cover four points in plain words:

  • what happened
  • who the letter is for
  • what you want
  • the time frame for a reply

Keep each point short.

How do I send the letter?

Choose a delivery method that leaves a record, such as registered mail or hand delivery. Depending on the situation, you can also send it by email. Keep a copy and save any receipt or delivery confirmation.

Is a demand letter the same as a letter of intent?

The two are closely related, and people often use the terms for the same document. A demand letter asks the other side to do something, such as pay an amount or fix a problem. If you only need to make a request regarding a payment or a repair, start with our demand letter form.

Can I use the sample as a template?

Yes, use it as a starting point. Replace the names, addresses, dates and amounts with your own, and adjust the facts and the settlement offer to fit your case. Templates you find online may be organized differently, so keep the parts that match your situation.

What kinds of disputes can a letter of intent cover?

It can describe a broken contract, an unpaid bill, property damage or a workplace problem. Give the dates and the facts. If you have several claims, give each one its own short paragraph.

Does sending the letter mean I will go to court?

No. It is a first step that gives both sides a chance to settle. If the other side agrees to your terms, you may not need to file anything. If it does not, you can decide on further legal action.

Should I ask a lawyer to review my letter of intent?

It can help, especially when a large amount of money or a complex case is involved. A lawyer can check your facts, your wording and the legal side of your claim before you send it.
