How to Remedy (5 steps)

1. Negotiate the Breach or Nonpayment

Attempt to settle the issue informally once a breach of contract or delinquency in payment is confirmed. Also, make sure to document all communication.

2. Formal Notice or Warning

3. Develop Then Send the Demand Letter

Write a demand letter summarizing the issue (e.g., change orders, missed payments) and seeking a remedy should the offending party continue to be uncooperative.

  • Begin with a professional header (e.g., company banner, logo).
  • Point out delinquent payments or explicitly state the offending action.
  • Discuss the potential legal remedies and options that could resolve the issue.
  • State when the desired remedy is expected by stating a deadline or cure period.
  • Present a resolution opportunity and close professionally and amicably.

4. Give Ample Time To Respond

Allow the deadline given for a response to arrive from the recipient. Generally, most letters grant a 7-15 day window for the recipient to respond.

5. Enforce Your Rights If They Don’t Comply

Explore additional options that rectify the issue in cases where the client ignores the letter, refuses to take action, or becomes hostile:

  • A third-party neutral arbitrator can be obtained (e.g., Better Business Bureau).
  • File a grievance with a body that provides oversight, such as a licensing board.
  • A mechanic’s lien can be placed on the property through the courts.
  • A lawsuit can be initiated and pursued (e.g., civil suits, quantum meruit).
