Wyoming Lien Deadlines for Material Suppliers
Wyoming material suppliers must send a preliminary notice, leave time for a separate notice of intent, and compare last furnishing with project substantial completion before filing.
Public date calculations cover Florida and Kansas. Wyoming dates require qualified review.
Risk context
Wyoming is High Risk for Suppliers
The ordinary materialman filing period is 120 days after the earlier of last furnishing and project substantial completion. Confirm that you qualify as a materialman: Wyoming distinguishes a person supplying materials without performing work from a contractor or working subcontractor. A direct-owner purchase alone does not settle a disputed classification.

Scroll sideways to see all deadline details.
| Deadline Type | Timing | Details |
|---|---|---|
| Preliminary Notice | Send within 30 days after first furnishing | Materialmen notify the record owner or agent and provide the required contractor copy. Late notice bars lien rights. |
| Notice of Intent | Send at least 20 days before filing the lien statement | Notify the record owner or agent of the claim amount and who owes it. This is separate from the preliminary notice. |
| Lien Filing Deadline | 120 days after the earlier of last furnishing or substantial completion | Applies to the ordinary materialman route. Confirm completion evidence and file with the county clerk. |
| Enforcement Deadline | 180 days after lien filing | Commence the foreclosure or enforcement action within this period. |
| Statutes | Governing statutes | Wyo. Stat. §§29-1-201, 29-1-312, 29-2-106, 29-2-107, 29-2-109 and 29-2-112 |
Keep the required steps distinct:
- Establish recipients and classification. Review the contract chain for the contractor-copy requirement, including owner-hired and lower-tier suppliers. A mixed work-and-material contract may follow a different route, including a different filing period.
- Check substantial completion. A recorded completion notice creates a rebuttable presumption; it cannot extend a deadline that otherwise falls earlier. Unknown or disputed completion, or an extension agreement, requires review before relying on a date.
- Allow time before and after filing. The 20-day notice of intent must precede the lien statement. Section 29-1-312 also requires notice after filing; recording alone does not finish the process.
Supplier pitfalls
Common Supplier Mistakes in Wyoming
Missing the 30-day Preliminary Notice
Section 29-2-112 bars a lien when the required preliminary notice is not sent on time. Keep proof of sending and verify recipients. Missing owner information does not establish an extension.
Counting only from the last delivery
Substantial completion can occur earlier and control the 120-day period. Do not substitute an assumed completion date or the contractor's 150-day period. A weekend or holiday cutoff needs specific review before relying on an extension.
Missing the 180-day enforcement deadline
Section 29-2-109 requires an action within 180 days after filing. Property-interest, leasehold, and homestead questions may also affect the available remedy.

Common questions
Frequently Asked Questions
Does every Wyoming supplier have 120 days after its last delivery?
No. For the ordinary materialman route, compare last furnishing with substantial completion and use the earlier event. Classification, a recorded completion notice, or a valid extension agreement may require further review.
Does the 30-day preliminary notice replace the notice of intent?
No. Section 29-2-107 requires a separate notice of intent at least 20 days before the lien statement is filed. Sending the preliminary notice does not satisfy that later step.
Can a late Wyoming preliminary notice preserve later deliveries?
Section 29-2-112 states that failure to send the required notice within the prescribed period bars the lien. Do not assume that late notice cures the failure or restarts a filing period.
