In many states, no — and this is the most expensive mistake in construction payments. States like California (20-day preliminary notice), Texas (monthly notices), Florida (Notice to Owner within 45 days) and Washington (60 days) condition some or all lien rights on an early notice sent near the start of your work, long before any payment problem exists.
If your state requires it and you skipped it, your lien may be invalid no matter how legitimate the debt. Some states offer partial recovery (a late notice covering recent work); others don't. The safe habit is to send preliminary notices on every job as routine paperwork — they're not aggressive, and in most states they're simply standard practice.
