Demand Letters for Construction Payment Disputes
Before filing a lien or lawsuit, a well-crafted demand letter from an attorney often resolves construction payment disputes quickly — and at far lower cost. It also creates a record of your attempts to resolve the matter in good faith.
Why Send a Demand Letter?
Many construction payment disputes — even significant ones — resolve after the other party receives a formal attorney demand letter. The letter signals that you are serious, that you understand your legal rights, and that litigation is the next step if the matter is not resolved. For many contractors and property owners, that is enough to prompt a settlement conversation.
A demand letter also documents that you gave the other party an opportunity to resolve the matter before you escalated to lien filings or litigation. This can be important in court if the other party claims you acted in bad faith or refused to negotiate.
What an Effective Demand Letter Includes
- The factual basis for the claim: Dates of work, contract amount, payments received, and the balance owed
- The legal basis: Breach of contract, prompt payment violation, quantum meruit, or other applicable theories
- Documentation references: The contract, invoices, change orders, and correspondence that support your claim
- A specific demand: The exact dollar amount you are seeking
- A response deadline: Typically 10–14 days, after which you will proceed with lien filing and/or litigation
- Consequences of non-response: What specific legal actions you will take — mechanics lien recording, stop payment notice, civil lawsuit
Timing: Demand Letter vs. Lien Deadlines
A demand letter should never delay your lien filing past the statutory deadline. These are parallel tracks — you can send a demand letter and still record a mechanics lien within the required timeframe. If the deadline is approaching, file the lien first and send the demand letter simultaneously.
When a Letter Is Not Enough
If the other party denies liability, ignores the demand, or proposes an unreasonably low settlement, your next step is the formal legal remedies: mechanics lien recording, stop payment notice, and ultimately lien foreclosure or civil lawsuit.
Frequently Asked Questions
What should a construction demand letter include?
An effective demand letter states: the factual basis for the claim (dates, contract amount, payments received, balance owed), the legal basis (breach of contract, prompt payment violation), specific dollar amount demanded, a response deadline of 10-14 days, and the specific legal actions that will follow if not resolved.
Does a demand letter preserve my mechanics lien deadline?
No. A demand letter does not stop any statutory deadlines from running. If your mechanics lien filing deadline is approaching, file the lien first — the demand letter and lien recording can and should happen simultaneously.
