What do I need to know about final payment and mechanics liens?
Short answer
Get the punch list signed off and the final payment collected before you release lien rights. Your state's lien process has specific deadlines, check them before you need them.
Final payment is where leverage disappears
Once the job is fully done and you've handed over keys or access, your leverage to collect drops fast. That's why final payment should be the smallest of your draws (5 to 10%), tied to a specific written punch list, not the biggest chunk of the contract sitting on trust at the very end.
If a customer is slow-walking final payment after a completed, signed-off punch list, that's the point to send a clear written notice with a deadline before you consider any further step.
Lien rights exist, but the process is state-specific
A mechanics lien is a legal claim against the property for unpaid work, and it can be a real tool to collect what you're owed. But the rules for who can file, what notices you had to send earlier in the job, and how long you have to file are all set at the state level, and missing an early notice deadline can void your lien rights entirely.
Don't wait until you have a collection problem to learn your state's lien process. Look it up (or ask a construction attorney) before your next job so any required preliminary notices go out on time, that step alone is often what determines whether a lien is even available to you later.
Protecting your right to collect
- 1.Learn whether your state requires a preliminary/prelien notice, and by when, before the job even starts.
- 2.Keep final payment as a small, clearly defined draw tied to a written, signed punch list.
- 3.Send a written notice with a firm deadline if final payment stalls after signoff.
- 4.Know your state's specific deadline to file a lien if it comes to that, these are usually short and unforgiving.
- 5.Keep every signed document (contract, change orders, punch list) in one file per job, you'll need them if a payment dispute ever escalates.
Where owners get this wrong
- Waiting until payment is already a problem to learn the lien process.
- Skipping a required preliminary notice early in the job, which can void lien rights later.
- Letting final payment sit as a large chunk of the contract instead of a small closeout draw.
Worth knowing: Mechanics lien law is entirely state-specific, including notice requirements, filing deadlines, and who qualifies to file. This is not legal advice. Check your state's lien statute or talk to a construction attorney before relying on lien rights to collect.
