Subcontractors do the work. They deserve to get paid for it.

Every year, small subcontractors and suppliers lose real money, not because they did anything wrong, but because they missed a deadline they never knew was running. Mechanic's-lien law is the strongest tool a tradesperson has to force payment, and it is also one of the most unforgiving: a single late notice can quietly extinguish a claim worth tens of thousands of dollars.

LienAlert exists to make that failure mode impossible. You tell us the facts of a job once. We compute every notice, filing, and suit deadline for your state and remind you, well ahead of time, and again as the date approaches, so the calendar can never quietly cost you a paycheck.

The principles we build on

Stay on the safe side of the law.

We are not a law firm and we never pretend to be. LienAlert does mechanical date math from the facts you enter and gives you blank forms you fill in and file yourself. It does not give legal advice and does not prepare or file documents for you. That line matters, and we hold it deliberately.

Be deterministic, not clever.

Deadlines are computed by tested, transparent rules, never by an AI guessing. We can show you exactly how each date was derived and which statute it comes from.

Expand only where we've done the work.

We turn a state on once we've built its deadline rules from that state's own statutes, and we tell you plainly to confirm them with a local attorney before you rely on them. We would rather get a state right than slap up fifty we haven't done the work on.
