Most general contractors collect waivers from the parties they pay. It feels complete: you know every sub on the job, you pay them, you get a waiver back. Clean.
The gap is that lien rights don’t follow your checkbook. In most states they follow who furnished labor or materials to the project — and that includes people who have no contract with you at all.
The three tiers
First tier: your direct subs. You have a contract, you pay them, you collect their waiver. This part almost never fails, because the payment and the waiver are the same conversation.
Second tier: their subs and suppliers. The framing sub’s lumber yard. The mechanical sub’s sheet-metal fabricator. The electrician’s crew if the electrician is themselves a sub to your electrical contractor. You’ve never paid these parties. In most states, they can still record a lien against the property — because they furnished to the project, not to you.
Suppliers to suppliers. Rights usually thin out at some depth, and where they stop varies by state. Don’t assume — this is one of the details worth confirming for your state rather than generalizing.
The middle tier is where the money is, and where the surprises live.
Bottom line: the waiver you’re missing is almost never from a sub you forgot. It’s from someone one tier down that you never knew was on the job.
Why the second tier is the dangerous one
Three reasons it goes wrong specifically:
- You don’t have a list. You know your subs because you signed contracts with them. You don’t automatically know who they bought from.
- Paying your sub doesn’t protect you. If you pay the framing sub in full and they don’t pay the lumber yard, the lumber yard’s rights against the property are typically unaffected by your payment. This is the “paying twice” scenario, and it’s the reason waivers exist at all.
- Nobody tells you until it’s too late. A second-tier supplier’s first contact with you is often the lien itself, or a preliminary notice you filed away without acting on.
Preliminary notices are your roster
That last point cuts both ways, and it’s the most useful habit in this whole article: preliminary notices are how the second tier introduces itself.
In many states, a party without a direct contract with the owner or GC has to send a notice early in the job to preserve lien rights. Those notices arrive, get glanced at, and get filed. Treated properly, they’re a roster of exactly who can lien you — assembled and delivered for free, by the parties themselves.
Build the habit: every preliminary notice that arrives becomes a row on your waiver tracker, tied to the sub it came through. Now the second tier is visible from the start rather than discovered at closeout. (More on the mechanics in preliminary notice and lien waivers.)
Notice requirements and deadlines vary a lot between states — check yours in the lien waivers by state guide.
The other three ways to find them
Notices won’t catch everyone. Fill the gaps with:
- Ask in the subcontract. Require each sub to identify their suppliers and lower-tier subs above some dollar threshold, and to update the list as it changes. Cheap to add, and it makes the roster contractual instead of hopeful.
- Read the sub’s own paperwork. Pay applications and schedules of values often name the major suppliers outright.
- Require conditional waivers down the chain. For significant second-tier parties, make the sub’s payment contingent on producing waivers from the parties underneath them. This is the strongest tool you have, and it works because it moves the collection problem to the party who actually has the relationship.
Tracking it without losing your mind
The practical consequence is that your waiver tracker needs a tier column, and rows for parties you will never pay directly. A sheet organized around your payments will structurally miss the second tier, because those parties generate no payment event on your side to hang a row on.
That’s the reason a tier field matters more than it looks: it’s the difference between tracking your disbursements and tracking your actual lien exposure. (The full column list.)
ClearLien auto-drafts waivers for the subs you pay in QuickBooks — the first tier handles itself once the payment clears — which frees up the attention that first tier was consuming for the one that actually needs judgment. You can also generate a waiver free for a second-tier supplier who isn’t in your payment flow at all.
