Frequently Asked Questions

Is a demand letter legally required before suing?

In most cases, no. However, judges often look favorably on plaintiffs who attempted to resolve the matter before filing suit. Some contracts and certain types of claims do require written notice first.

How long should I give them to respond?

Typically 14-30 days is reasonable. For larger amounts or complex situations, 30 days is appropriate. For smaller, straightforward claims, 14 days is sufficient.

Should I send it by certified mail?

Yes. Always send via certified mail with return receipt requested. This provides proof that the letter was delivered, which can be important evidence in court.

What if they don't respond to my demand letter?

If they ignore your demand letter or refuse to pay, you can proceed with filing in small claims court. Bring the letter and proof of delivery as evidence.

Can a demand letter hurt my case?

If written properly, no. Avoid threats, insults, or exaggerated claims. Stick to facts and be professional. A poorly written letter could potentially be used against you.
