How to Write an Effective Demand Letter
A clear, professional demand letter often resolves disputes without litigation.
Structure
- Facts summary (who/what/when)
- Legal basis (contract clause or statute)
- Demand (amount/action) and deadline
- Consequences of non‑compliance (litigation, interest, costs)
Tone & evidence
Stay factual and respectful. Attach key exhibits as numbered annexes. Avoid threats or insults.
Delivery
Use content‑certified mail (내용증명) and keep receipts. Email can supplement but not replace formal service.
