Demand Letter
Definition
A formal written notice sent to someone who owes you money or has breached a contract, demanding they fix the problem within a specific timeframe. It's the 'pay up or I'm taking legal action' letter — usually the last step before a lawsuit.
In Practice
A client owes you $8,000 for completed work and has ignored your invoices for 60 days. You send a demand letter giving them 15 days to pay, explaining that you'll pursue legal action if they don't. About 30–40% of demand letters result in payment without ever going to court. They work because they signal you're serious.

Frequently asked questions about demand letter
No, but a letter from a lawyer carries more weight. You can write and send your own demand letter, and it's legally valid. However, a letter on a law firm's letterhead tends to get faster results — it shows you've already hired representation. For debts under $5,000, a well-written personal letter is usually enough.
