Mechanic's Lien Deadlines & Notice Requirements in Nebraska

At a glance

Requirements one by one

Governing law

Nebraska's private construction lien lives in the Nebraska Construction Lien Act, Neb. Rev. Stat. §§ 52-125 to 52-159, enacted in 1981 (LB 512). Section 52-125 deliberately uses "construction lien" rather than "mechanic's lien." Nebraska's own courts have noted that the Act is "an almost verbatim version of article 5 of the Uniform Simplification of Land Transfers Act" — Nebraska is one of only a handful of states that adopted that particular uniform lien scheme, which explains some of its distinctive vocabulary ("contracting owner," "real estate improvement contract," "notice of commencement") that differs from most other states' lien statutes.

Who can claim

Under § 52-131(1), "a person who furnishes services or materials pursuant to a real estate improvement contract has a construction lien ... to secure the payment of his or her contract price." Nebraska courts have read this expansively. In Blue Tee Corp. v. CDI Contractors, the Nebraska Supreme Court held that a supplier to a subcontractor may file and enforce a lien against the property owner — but that a supplier to a supplier or materialman may not. A later Court of Appeals decision relied on that same distinction to hold that a subcontractor's own union employees (and, by extension, the trustees of their health and pension plans, standing in as their assignees) may assert a construction lien for unpaid wage contributions, reasoning that their relationship to the property owner is "substantially no different" from a supplier-to-subcontractor relationship. What counts as a covered "real estate improvement contract" is itself defined broadly in § 52-130: labor or materials to change the physical condition of land or a structure, including "preparation of plans, surveys, or architectural or engineering plans or drawings ... whether or not used" — but the same section excludes contracts for mining, timber removal, or crop harvesting.

Preliminary notice

No claimant has to send any notice before filing a lien. Under § 52-135(1), the "Notice of Right to Assert a Lien" is something a claimant "may" send "at any time after" entering the contract — never a condition of the lien itself. And critically, § 52-135(6) limits when the section even applies at all: "This section shall apply to a lien claimant only when the contracting owner is a protected party." Outside a protected-party deal, sending or skipping this notice has no described consequence under the Act. Inside one, it matters a great deal — see "Homestead/residential extras" below.

Deadline to file the lien

Under § 52-137(1), one flat deadline applies to everyone: a claimant's lien "does not attach and may not be enforced unless ... not later than one hundred twenty days after his or her final furnishing of services or materials, he or she has recorded a lien." Unlike states that give the prime contractor a longer window than subcontractors, Nebraska runs the same 120 days for every claimant tier.

Notice of completion effect

Nothing in the Act lets an owner shorten the 120-day filing deadline with a recorded notice of completion. Nebraska does have a "notice of commencement" device under § 52-145(1) and § 52-145(5), recordable by the owner or, if no notice applies, by a claimant, but it answers a different question: lien priority against competing lenders and purchasers, not the filing deadline. A claimant who records one must send a copy to the owner no later than the recording day; missing that step can create damages liability (§ 52-145(6)). Section 52-137(2) explains that while an effective notice of commencement is on record, a lien recorded later "attaches as of the time the notice is recorded, even though visible commencement occurred before the notice is recorded" — a priority rule, not a deadline-shortening one. The 120-day filing clock keeps running from the claimant's own final furnishing date regardless of any notice of commencement.

Serving the lien on the owner

Section 52-135(3) says the claimant shall “send a copy of a recorded lien to the contracting owner within ten days after recording.” Subsection 52-135(6) confines that section to claimants whose contracting owner is a protected party. The statute does not spell out a separate forfeiture penalty for missing this step. For a protected-party owner, receipt of the copy can also affect the lien-amount cap described next.

Deadline to sue to foreclose

Under § 52-140(1), a recorded lien has two years of enforceability by default. But § 52-140(2) lets anyone with a stake in the property — "an owner, holder of a security interest, or other person having an interest in the real estate" — force the issue early: after a written demand to sue, the claimant has only 30 days: "the claimant institutes judicial proceedings or records an affidavit that the total contract price is not yet due under the contract for which he or she recorded the lien," or the lien lapses.

Homestead/residential extras

Nebraska's residential rule is built around the "protected party" definition in § 52-129: an individual who contracts to buy, improve, or give a security interest in residential real estate of "not more than four dwelling units" that they occupy or intend to occupy, plus certain people related to such an occupant. A qualifying condominium remains residential real estate even when its development has more than four units or some nonresidential units (§ 52-129(2)). Two consequences follow only for a protected-party owner. First, the optional preliminary notice actually does something — it's the trigger described above. Second, § 52-136(2) caps a non-prime-contractor's lien at the lesser of what's owed under the claimant's own contract or "the amount unpaid under the prime contract ... at the time the contracting owner receives the claimant's notice of the right to assert a lien" (or, per § 52-136(5), a copy of the recorded lien if no earlier notice was sent) — a real ceiling that simply doesn't exist for a non-protected-party owner, whose claimants under § 52-136(1)(b) get the full amount unpaid on their own contract regardless of what the owner has already paid the prime contractor.

What trips people up

The "protected party" gate is the single biggest thing to get right in Nebraska, because it flips two different rules on and off at once: skip the optional notice on a protected-party job, thinking notice is "always optional" (which is technically true), and a subcontractor risks having their eventual lien capped at whatever's left on the prime contract by the time the owner finally sees a copy of the recorded lien — often much less than what the sub is actually owed, especially if the owner has been steadily paying the general contractor in the meantime. Second, don't confuse Nebraska's "notice of commencement" with a notice of completion from other states: it's recorded near the START of a project (by the owner or, if none exists, by a claimant), and it only fixes a priority date against third parties like lenders — it has no bearing on the 120-day filing deadline itself. Third, the tier limit here isn't about counting subcontractor levels the way some states do; it turns on whether the claimant's own relationship is with someone actually performing work (a subcontractor) versus another supplier — a supplier to a subcontractor is covered, but a supplier to that supplier is not, regardless of how many "tiers" down the project chain that sounds like.

Common questions

Do I need to send a notice before I start work in Nebraska? No — no preliminary notice is required to preserve lien rights on any job. An optional "Notice of Right to Assert a Lien" exists, but it only has legal significance when the owner is a "protected party" (residential, 4 units or fewer, owner-occupied).

I supplied materials to another supplier, not a contractor or subcontractor. Do I have lien rights? No. Nebraska courts have held that a supplier to a supplier or materialman has no construction lien rights under the Act, even though a supplier to a subcontractor does.

What happens if the owner demands that I sue to enforce my lien? You get only 30 days from receiving that written demand to either file suit or record an affidavit that the contract price isn't yet due — miss both, and the lien lapses even though the normal enforcement window would otherwise run two years (§ 52-140(2)).
