When one party fails to fulfill a contractual obligation—such as failing to pay, deliver goods, or complete work—the other party has the legal right to file a claim for damages.

Real-Life Example:
Mr. Somchai contracted a construction company to renovate his home for 500,000 baht, with payments to be made in installments. After receiving 300,000 baht, the company abandoned the project without completing the work. Mr. Somchai had to hire another contractor to finish the job, costing him an additional 200,000 baht.

In this situation, Mr. Somchai can file a lawsuit to claim damages from the original company.

Types of damages that may be claimed include:

• Extra expenses incurred from hiring another party
• Loss of business opportunities or use of the property
• Time and effort spent resolving the issue
  

Supporting evidence such as contracts, receipts, messages, and photographs will help prove the breach and extent of the loss.
