Illinois Demand Letter FAQ


What is a Demand Letter?

A demand letter is a letter stating a legal claim which makes a demand for restitution or performance of some obligation, owing to the recipients' alleged breach of contract, or for a legal wrong. Although demand letters are not legally required they are frequently used, especially in contract law, tort law, and commercial law cases.


When to use a Demand Letter?

A Demand Letter should be written when the other party violates the terms of a contract, fails to pay a debt, or fails to fulfill its obligations within the established time frame. Such a letter is sent to formally demand fulfillment of obligations and provide an opportunity to voluntarily eliminate the violation. It should also be used when it is necessary to record the fact of filing a claim before a possible lawsuit.


What should be written in a Demand Letter?

There is no specific length to the letter, although ideally, shorter is better. The text should be long enough to clearly explain your intent. The effectiveness of the letter is reduced if it goes beyond this, so the writer should make sure that it does not deviate from the facts.

A demand letter should contain the following information:

  • The purpose of the letter;

  • The parties involved;

  • The date and time of the complaint;

  • A description of the damages suffered;

  • The request for restitution.

Most demand letters provide a specific time frame for resolving the dispute, and also describe the possible consequences for the recipient if the conditions set out by the sender are not met.

It is important to consider the tone of the letter. Try to be direct and serious, avoiding any hints of threat - this can cause a negative reaction from the recipient.


What to do if no one responds to the Demand Letter?

If the recipient does not respond to your demand letter, you can take additional legal steps to encourage them to resolve the issue. It is advisable to contact a lawyer who specializes in the relevant area of law to obtain professional advice. You may also send a follow-up letter by registered or certified mail to have official confirmation of its delivery. If there is still no response, you may need to file a formal complaint with the appropriate authority to initiate court proceedings. Throughout the process, make sure to document all communication attempts, as these records can serve as important evidence in court.


What should I do if I receive a Demand Letter?

If you get a Demand Letter, don’t ignore it. Read it carefully and make sure you understand what the sender is asking for. Keep all related papers, messages, or receipts that can help you explain your side of the story. It’s a good idea to talk to a lawyer soon, even if you’re not sure the claim is real — they can tell you what the letter means, what your options are, and help you write the right kind of response. If you believe the claim is fair, you can try to solve the problem directly, such as paying what’s owed or agreeing on a plan to fix it. If you think the claim is wrong, your lawyer can help you answer clearly and protect your rights. Whatever you do, keep copies of everything you send or receive — this can be very helpful later if things go further.
