Where small contractors lose payment rights
Most lost lien rights come down to paperwork that was late, wrong, or never filed.
Every state has its own rulebook:
Who gets served, by when, and what starts the clock all change by state and by project type. Working in 3 states means tracking 3 sets of deadlines.
Late notice, smaller claim:
In some states a late preliminary notice only protects work done after it was served. The work you did before that can fall outside your lien rights.
Waivers signed for the wrong amount:
A waiver signed for more than you were paid can give away rights to money you are still owed.
Waivers in a spreadsheet:
Tracking waivers by email and memory means a missing one holds up a draw, or a signed one cannot be found when you need it.
