Suppose you are biting into a delicious snack cake only to be met with a big chunk of wax paper. Or perhaps you purchased a bicycle that fell apart the second time you took it out for a spin. You could file a defective product lawsuit, but that would likely be costly and time consuming. What you may consider as an alternative is sending the business a Complaint Letter.


The Complaint Letter is a simple, but powerful legal document that is sent to inform a business that a product or service they provided was defective. It gives the recipient a chance to correct a mistake without the need for legal action.

Frequently Asked Questions

  • The sender’s contact information;
  • The recipient’s contact information;
  • The date and method of delivery of the letter;
  • The type of complaint;

  • A proposed remedy;
  • Describe the action you want the recipient to take to correct the deficient products/services. Examples include “full reimbursement of the product/service,” “repair of the product,” and “replacement of the product.”
