Mechanic's lien
Best for: Unpaid work that improved private property
Pros
- Attaches to the property itself and blocks a clean sale, refinance or loan until you are paid
- Most liens settle on the title cloud alone, with no lawsuit
- In most states it survives the owner having paid a GC who never passed it on
Cons
- Every state sets its own clock from your last day of work, often with an earlier preliminary notice
- Unlicensed where the trade needs a license usually means no lien at all
- Pays out from equity above the loans already on the property; government property cannot be liened
