Delaware Construction Lien Guide
Delaware mechanics lien law allows contractors and suppliers to secure payment for labor, materials, equipment, and professional services that improve real property. Delaware is a strict-compliance state, meaning courts expect lien claimants to follow the statute precisely. Missing a deadline or required step can completely eliminate lien rights.
Keep in mind that Delaware Mechanics Lien, Construction Lien and Claim of Liencan be used interchangeably.

General contractors
Subcontractors
Sub-subcontractors

Laborers
Architects, engineers, surveyors, and other design professionals
Lien rights apply to private construction projects.
⭐ Delaware Lien Deadlines (Critical)
Delaware does not require a preliminary notice, notice to owner, or notice of intent to lien before filing a mechanics lien. Instead, Delaware protects owners through short filing and enforcement deadlines and mandatory service of court pleadings, rather than pre-lien notice requirements.
Deadline #1 — File the Delaware Mechanics Lien
A Delaware mechanics lien must be filed with the Prothonotary (Clerk of the Superior Court) in the county where the property is located:
Within 90 days after the claimant’s last furnishing
This is a hard deadline. Missing it results in a complete loss of lien rights.
Deadline #2 — Enforce the Delaware Mechanics Lien
Delaware mechanics liens are not self-executing. To preserve the lien, the claimant must:
Commence an action to enforce the lien within 180 days after filing
If enforcement is not timely commenced, the lien automatically expires and becomes unenforceable.
