Michigan Contractor Lien Law: Rights and Procedures

Michigan's Construction Lien Act, codified at MCL 570.1101 through MCL 570.1305, establishes the statutory framework governing how contractors, subcontractors, suppliers, and laborers secure payment claims against real property. The law creates a structured system of preliminary notices, lien filings, and enforcement deadlines that must be followed precisely to preserve lien rights. Understanding where these rights begin and end is essential for any participant in Michigan construction — from licensed residential builders to commercial subcontractors operating on multi-prime projects.

Definition and Scope

The Michigan Construction Lien Act (MCL 570.1101 et seq.) grants contractors, subcontractors, sub-subcontractors, suppliers, and laborers a security interest in real property when services or materials are furnished for the improvement of that property and payment is not received. A construction lien, once properly recorded, attaches to the property and gives the claimant priority rights that can be enforced through foreclosure proceedings in circuit court.

The Act covers improvements to real property in Michigan, including new construction, renovation, repair, and demolition services. Coverage extends to both residential and commercial projects, though the procedural requirements differ materially between the two categories.

Geographic and legal scope: The Michigan Construction Lien Act applies exclusively to real property located within Michigan's borders. Federal projects — including construction on federally owned land — fall outside state lien law jurisdiction and are instead governed by the Miller Act (40 U.S.C. §§ 3131–3134), which requires payment bonds rather than permitting property liens. Public projects funded by Michigan state or local governments are similarly excluded from the Construction Lien Act; payment bond claims under the Michigan Public Works Bond Act (MCL 129.201) govern those situations. Private residential and commercial projects on privately held land constitute the primary scope of the Act.

Contractors operating in Michigan should also review Michigan contractor licensing requirements and Michigan contractor contract requirements, as licensure status and contract form can affect lien enforceability.

Core Mechanics or Structure

The Michigan Construction Lien Act operates through three sequential mechanisms: the Notice of Furnishing, the Claim of Lien, and foreclosure.

Notice of Furnishing
Subcontractors, sub-subcontractors, and suppliers — those without a direct contract with the property owner — must serve a Notice of Furnishing on the designee named in the posted Notice of Commencement. Under MCL 570.1109, this notice must be served within 20 days of first furnishing labor or materials. Failure to serve timely limits the claimant's lien to work performed in the 20-day period before the notice is served plus all work performed afterward.

Notice of Commencement
The property owner or general contractor must record a Notice of Commencement with the county register of deeds before construction begins or within 10 days after the first furnishing of labor or materials (MCL 570.1108). This document designates a lien designee and is the instrument that triggers the Notice of Furnishing requirement for downstream claimants.

Claim of Lien
A Claim of Lien must be recorded with the register of deeds in the county where the property is located. Under MCL 570.1111, the deadline is 90 days after the last date of furnishing labor, materials, or services. The lien must contain a legal description of the property, the amount claimed, the name of the owner, and the claimant's identifying information.

Foreclosure
A lien that is not discharged by payment, bond, or court order must be enforced through circuit court foreclosure. Under MCL 570.1117, foreclosure suit must be filed within 1 year of the date the Claim of Lien was recorded. Failure to file within this window extinguishes the lien by operation of law.

Causal Relationships or Drivers

The Act's procedural requirements exist because of structural information asymmetries in construction payment chains. Property owners frequently have no direct knowledge of lower-tier subcontractors or suppliers furnishing work on their projects. The Notice of Commencement and Notice of Furnishing requirements create a documented communication channel: owners learn who is performing work; claimants learn the identity of the lien designee.

Payment defaults — the primary trigger for lien activity — typically arise from general contractor insolvency, disputed change orders, or deliberate withholding. When a general contractor becomes insolvent mid-project, subcontractors who served timely Notices of Furnishing retain lien rights against the owner's property even though the owner may have already paid the general contractor in full. This dynamic — known as the "double payment" risk — is the central economic tension the Act attempts to manage through its waiver and discharge mechanisms.

Lien waivers embedded in pay applications create another causal chain: when a subcontractor signs a waiver of lien rights as a condition of receiving partial payment, that waiver limits future lien claims to amounts not yet paid, as governed by MCL 570.1115.

Classification Boundaries

Tier 1 — Prime Contractors (Direct Contract with Owner)
Prime contractors hold direct contractual privity with the property owner. They are not required to serve a Notice of Furnishing. Their right to lien attaches by virtue of the contract itself and the performance of work.

Tier 2 — Subcontractors and Suppliers (Contract with Prime)
These parties contract with the prime contractor, not the owner. A valid Notice of Furnishing, served within 20 days of first furnishing, is mandatory to preserve full lien rights.

Tier 3 — Sub-Subcontractors and Remote Suppliers (Contract with Subcontractor)
Parties at this tier face identical Notice of Furnishing requirements as Tier 2 claimants. Their lien rights run against the property, not merely against the party who hired them.

Laborers
Individual laborers have lien rights under MCL 570.1107 and are exempt from the Notice of Furnishing requirement, provided they file a Claim of Lien within 90 days of their last day of work.

Design Professionals
Architects, engineers, and surveyors who provide services resulting in the actual improvement of real property may assert construction liens under the Act, subject to the same 90-day filing deadline.

Tradeoffs and Tensions

The Act creates deliberate friction between property owner protection and payment security for contractors. Three principal tensions emerge:

Prompt Payment vs. Lien Discharge
Property owners who pay their general contractor in full before subcontractors file liens may still face lien exposure if Notices of Furnishing were properly served. The Act places the burden on owners to collect lien waivers from all known claimants at each payment milestone — a logistically demanding obligation on large projects.

Speed vs. Documentation
The 20-day Notice of Furnishing window incentivizes rapid paperwork at project start, but construction mobilization is inherently chaotic. Contractors who begin work before formal notice obligations are understood routinely lose lien rights for early work — rights that cannot be recovered.

Residential Owner Protections vs. Contractor Rights
The Act provides stronger protections for residential property owners through sworn statements. Under MCL 570.1110, a prime contractor must provide a sworn statement listing all subcontractors and suppliers before receiving payment. Residential owners who rely on sworn statements and pay accordingly are partially shielded from double payment exposure. This protection does not apply equivalently in commercial settings.

Michigan's dispute resolution landscape for contractors often involves lien enforcement and defense as concurrent tracks.

Common Misconceptions

Misconception: A signed contract alone preserves lien rights.
A contract establishes the payment obligation but does not substitute for Notice of Furnishing. Subcontractors who rely on a written subcontract without serving a Notice of Furnishing will lose lien rights for work performed more than 20 days before the notice is delivered.

Misconception: Lien rights extend indefinitely as long as a dispute is ongoing.
The 90-day recording deadline and the 1-year foreclosure deadline are absolute. Ongoing payment negotiations do not toll these statutory clocks.

Misconception: Filing a lien guarantees payment.
A lien is a security interest, not a judgment. Enforcement requires circuit court foreclosure proceedings and a finding in the claimant's favor. A lien that is not foreclosed within 1 year is void.

Misconception: Unlicensed contractors can assert lien rights.
Under MCL 570.1104, a contractor who is required to hold a license and does not hold one at the time of contracting may be barred from asserting a construction lien. The Michigan licensed vs. unlicensed contractors reference covers the licensing implications in detail.

Misconception: The Notice of Commencement is the owner's optional paperwork.
Failure to record a Notice of Commencement does not eliminate subcontractor lien rights — it actually increases the owner's exposure by removing the mechanism that would otherwise limit lien claims to notified parties.

Checklist or Steps

The following sequence reflects the procedural elements of the Michigan Construction Lien Act as they apply to a subcontractor seeking to preserve lien rights:

1. Confirm the Notice of Commencement — Verify whether the prime contractor or owner has recorded a Notice of Commencement with the county register of deeds and posted it at the job site.
2. Identify the lien designee — The Notice of Commencement names the party who must receive the Notice of Furnishing.
3. Calculate the 20-day window — Count 20 calendar days from the date of first furnishing labor or materials.
4. Prepare the Notice of Furnishing — The notice must conform to the form specified in MCL 570.1109, including the claimant's name, address, description of services, and the property description.
5. Serve the Notice of Furnishing — Deliver by certified mail or personal service to the lien designee before the 20-day deadline expires.
6. Track the last furnishing date — The 90-day Claim of Lien deadline runs from the last date labor, materials, or services were furnished — not the contract end date or invoice date.
7. Prepare the Claim of Lien — Include the property legal description, owner name, claimant identity, amount claimed, and last furnishing date.
8. Record the Claim of Lien — File with the county register of deeds where the property is located within 90 days of the last furnishing date.
9. Serve notice of lien on owner — Under MCL 570.1112, a copy of the Claim of Lien must be served on the owner within 15 days of recording.
10. Monitor the 1-year foreclosure deadline — File a circuit court foreclosure action within 1 year of the Claim of Lien recording date or the lien becomes void.
