What is a demand letter?
A demand letter is a formal written notice sent to a client or property owner requesting payment for unpaid work.
A contractor demand letter typically includes:
- The amount owed
- Description of the work performed
- Payment deadline
- Notice of possible legal action if payment is not received
Demand letters are commonly used in construction disputes before escalating to legal actions such as mechanic's liens or lawsuits.
When contractors send a demand letter
- Payment is overdue
- The client stops responding
- Negotiations have failed
- The final invoice is ignored
In many situations, this step alone can prompt the client to pay.
What should a contractor demand letter include?
Project details
- Property address
- Client name
- Description of work performed
Payment information
- Invoice amount
- Outstanding balance
- Original payment terms
Payment deadline + Notice of further action
Most demand letters include a deadline (e.g. “Payment must be received within 10 days.”) and state that failure to resolve may lead to mechanic's lien, bond claim, or legal action.
Why demand letters often resolve disputes
A demand letter changes the situation by:
- Creating a formal written record
- Clearly outlining payment expectations
- Showing the contractor is prepared to escalate the dispute
Demand letter vs hiring a lawyer

Frequently Asked Questions
Can I send a demand letter without a lawyer?
Yes. Many contractors send demand letters themselves before escalating disputes. However, the structure and wording of the letter can influence how seriously it is taken.
How long should I give the client to respond?
Many demand letters provide a response window of 7–14 days, depending on the situation.
Should a demand letter mention a mechanic's lien?
Some demand letters mention the possibility of further legal steps, including mechanic's liens, if payment is not resolved.
Does a demand letter guarantee payment?
No. However, demand letters often help resolve disputes by signaling that the contractor intends to pursue payment formally.
