How to Handle a Subcontractor Who Files a Lien Mid-Project: The GC's 72-Hour Response Checklist

What a subcontractor lien mid-project actually does to your job

When a subcontractor files a lien mid-project, they record a mechanic's lien with the county recorder in the project's jurisdiction — a public filing that creates a cloud on title and prevents the property from being sold or refinanced until the lien is removed.

The more immediate problem for a GC is financing. Construction lenders run a title search at every draw advance. A recorded lien surfaces the same day it is filed, and most construction loan agreements give the lender the right to freeze draw disbursements until the lien is resolved. A single subcontractor's disputed invoice can lock cash flow for every other trade on the same project within hours.

Most construction contracts also require the GC to keep the property free and clear of all liens. A recorded lien is therefore both a financing problem and a potential contract breach with the owner — two separate pressure points the sub knows you are feeling.

The scenario almost always follows a predictable sequence. The sub submitted an invoice, sent emails, sent a Notice of Intent to Lien that no one with authority ever saw, and finally recorded a lien as the only lever left. Your first 72 hours determine whether this resolves in days or drags into litigation.

The documents to pull in the first four hours

Before calling the sub, pull the documents that tell you whether the lien is valid and whether the amount claimed is accurate. Those two questions determine which response path is available to you.

The recorded lien itself: retrieve a copy from the county recorder's website — most counties provide online public access. Confirm the claimant name, property address and legal description, and claimed amount. An inflated number that includes unapproved change orders or already-paid retainage is a defective lien in most states.

Your preliminary notice log: in California, a sub must serve preliminary notice within 20 days of first furnishing or loses lien rights entirely. In Florida the Notice to Owner must be served within 45 days. A sub that missed that window has filed an unenforceable lien, and that defect is a ground for removal before any payment discussion.

All lien waivers previously collected from this sub: a signed unconditional progress waiver covering the period the lien claims means the sub already released those rights in writing. That document is your primary defense.

All payment records for this sub: checks, wire confirmations, payment dates. Compare total paid against total billed and total claimed. A lien that overstates what is owed is challengeable on the overstated portion even if the underlying claim is otherwise legitimate.

Four ways to respond — and which fits your situation

Once you know whether the lien is valid, inflated, procedurally defective, or legitimate, you have four response paths. Most situations make one clearly correct.

Option 1 — Pay and obtain a release: If the amount is legitimate and owed, pay the undisputed amount. Require the sub to sign a Conditional Final Lien Waiver before or simultaneously with payment. The sub then files a Release of Lien with the same county recorder. This can resolve in days when both parties agree.

Option 2 — Bond over the lien: Purchase a lien release bond from a surety company. The bond substitutes for the property as security; the lien clears from title and the sub's rights run against the bond instead. Premium cost is typically 1–3% of the bond amount. Bond over when the project must continue, financing access must be restored quickly, and the dispute will take weeks or months to resolve.

Option 3 — Dispute and seek removal: If the lien has a procedural defect — missed preliminary notice deadline, prior unconditional waiver, or an overstated amount — send a written Demand for Release of Lien by certified mail. Cite the specific defect, attach a blank release form, and give a 10–14 day response deadline. No response: file a Petition to Expunge in the appropriate court. In most jurisdictions, the prevailing party in a lien validity challenge recovers attorney fees.

Option 4 — Negotiate a settlement: When the amount is genuinely disputed but the lien is not clearly invalid, negotiate a reduced settlement. Require a Conditional Final Lien Waiver as part of the settlement agreement in writing. Verbal agreements on lien releases are unenforceable.

How a mid-project lien freezes your draws — and what to tell your lender

The most acute business risk when a subcontractor files a lien mid-project is not the lien amount — it is the construction draw that freezes while you resolve it.

Get ahead of it. Call the lender before they run their next title search and find the lien on their own. Describe the situation, the amount in dispute, and which response path you are executing. Lenders have seen this before. A GC who presents a resolution plan — 'we are bonding this off by Thursday, the premium is $4,200, we will have title clearance confirmation by Friday' — is managing the relationship. A GC who goes silent while the lender discovers the lien themselves is starting a much harder conversation.

There is also a cascading risk that most articles do not address. If the frozen draw means you cannot pay other subcontractors on schedule, those subs have their own lien rights. A second or third lien filing from subs who were not part of the original dispute compounds the problem geometrically. The one-sub dispute that freezes draws for two or three weeks can, if cash flow is not restored, produce additional lien filings from trades that were paid on time right up until this incident.

For each sub you cannot pay on schedule during the freeze, communicate in writing, immediately. A sub who receives a dated written notice explaining the delay — with a specific resolution timeline — is far less likely to file than one who is simply not paid without explanation.

State-specific rules in California, Texas, and Florida

Lien law is state-specific and deadlines are short. Three states with the rules GCs most frequently need:

California: Sub must serve preliminary notice within 20 days of first furnishing or loses lien rights. Without a recorded Notice of Completion, the sub has 90 days from project completion to file; once a Notice of Completion is recorded, that window shrinks to 30 days. The sub has 90 days from lien recording to file a foreclosure lawsuit — extended to 6 months if the lien is bonded off. Bond amount: 125% of the lien claim. California SB 61, effective January 1, 2026, caps private-project retention at 5% for contracts executed on or after that date. A GC holding 10% retention on any post-2026 subcontract is holding funds beyond the statutory limit and has created a legitimate separate grievance for the sub — an important factor if the lien dispute involves withheld retainage.

Texas: Sub must send written notice of an unpaid claim by the 15th of the third month after the month unpaid work was performed — January work means the notice is due by April 15, and a separate notice is required for each unpaid month. The lien affidavit must be filed by the 15th of the fourth month after last services. The sub must send a copy of the filed lien to both the owner and the GC within 5 days of filing. Bond amount: 1.5 times the lien claim plus court costs. Enforcement lawsuit must be filed within 1 year of the lien affidavit.

Florida: The Notice to Owner must be served within 45 days of first furnishing — missing this deadline eliminates lien rights entirely and is a complete statutory defense for the GC. The lien itself must be filed within 90 days of last furnishing. A copy must be served on the owner within 15 days of filing. Enforcement deadline: 1 year from lien recording.

The waiver system that prevents this scenario from the start

A subcontractor who files a lien mid-project has, almost always, exhausted other options before recording. The mechanics of a lien filing are not spontaneous — they follow ignored invoices, unanswered notices, and a payment system that had no built-in accountability.

The preventive system is a draw-by-draw waiver cycle. Collect a conditional progress waiver from every sub and supplier with each pay application, before payment is issued. Once payment clears, collect the unconditional progress waiver within five business days. Embed the waiver submission deadline in the subcontract as a payment condition so collection is procedural rather than a monthly chase.

A sub who is current on waivers and still files a lien is filing on a period already covered by a signed unconditional waiver. That document is your defense. A sub who is behind on waivers because you stopped collecting them has leverage you should not have given them.

When a dispute does escalate, the documentation that matters most is the record of exactly what work was performed, when, and what was approved — phase photos with timestamps, milestone sign-offs, scope confirmations. WorkReceipt creates that timestamped record and delivers it as a professional report the same day. Paired with a waiver log, it answers the two questions every lien dispute turns on: was the work done, and was it paid.
