A lien is the last resort in the payment chain, but it's a real one: filed against the property itself, it creates pressure on the owner, the GC, and the lender because the property can't be sold or refinanced cleanly while it's outstanding. It doesn't guarantee payment, but it changes who's motivated to resolve the dispute.
Lien rights aren't automatic in most states — they depend on filing a preliminary notice within a set window after starting work, and missing that window can mean losing the right to file a lien at all, no matter how legitimate the unpaid balance is.
Example
A sub finishes $40,000 of electrical work and isn't paid after 90 days of follow-up. Because they filed the required preliminary notice at the start of the job, they're able to file a mechanics lien against the property, which stalls the owner's refinance until the balance is settled.
Where this goes wrong on real jobs
Liens land on property owners without warning precisely because the payment chain underneath them broke down unseen.
“I got served with a mechanic lien from the subcontractor on my property for $2500. I am pissed. I did everything right and I don't owe anyone any money.”
