Delaware Mechanic Lien Deadlines

Direct Contractors — 180-Day Filing Deadline

A contractor who has made a contract directly with the owner and has furnished both labor and materials must file a mechanic lien before the expiration of 180 days after completion of the project. 25 Del.C. §2711(a). No preliminary notice or other notices are required prior to filing.

This 180-day deadline applies specifically to contractors in direct privity with the property owner who have provided both labor and materials. Contractors who furnished only labor or only materials may be subject to different filing requirements and should consult the applicable statutory provisions.

Subcontractors & Suppliers — 120-Day Filing Deadline

All other persons who have performed or furnished labor or material, or both, must file a Statement of Claim within 120 days after completion of labor or last delivery of material. 25 Del.C. §2711(b). This category includes subcontractors, sub-subcontractors, material suppliers, and any other claimant not in direct privity with the owner.

The 120-day period begins to run from the completion of the claimant’s own labor or the last delivery of the claimant’s materials, not from the overall project completion date. Accurate record-keeping of the last date of furnishing is essential for calculating this deadline.

Small Claims — Labor Under $100

Any person performing labor with a value under $100 may file a Statement of Claim in the Justice of the Peace Court. The filing may be made not sooner than 20 days after the last labor performed, but must be filed within 30 days after the last performance. 25 Del.C. §2732.

This provision creates a narrow filing window for small labor claims, requiring claimants to wait at least 20 days but file no later than 30 days after the last labor is performed. Missing either boundary of this window will result in the loss of mechanic lien rights for the claim.

Definition of “Completion” for Direct Contractors

Completion of the project or structure is a critical concept in Delaware mechanic lien law because it triggers the 180-day filing deadline for direct contractors. Under 25 Del.C. §2711(a) 1-9, completion is defined as any one of the following events:

• The date of completion stated in the contract
• The date when the statute of limitation runs, as stated in the contract, for a specific phase or stage of a project, or for the entire project
• The date when the contractor receives payment of 90% of the contract price plus the amount of change orders
• The date the contractor submits a final invoice to the owner
• The date a certificate of occupancy is issued for the structure
• The date the owner accepts the structure
• The date the engineer or architect issues a certificate of completion
• The date permanent financing is completed

Definition of “Completion” for Subcontractors & Suppliers

For subcontractors and other non-direct claimants, the completion of labor or last delivery of material triggers the 120-day filing deadline. Under 25 Del.C. §2711(a) 1-9, this is defined as either:

• The date final payment, including retainage, is due to the claimant
• The date final payment is made to the contractor who has a contract with the owner to erect, alter, or repair a structure, and is to furnish labor and/or materials to perform the work

Minimum Claim Value & Filing Procedures

Delaware mechanic lien rights are available for projects with a value exceeding $25.00. Claims below this threshold do not qualify for mechanic lien protection under the statute. For claims of labor under $100, the Justice of the Peace Court has jurisdiction under the special small claims provisions of 25 Del.C. §2732.

The Statement of Claim must contain sufficient information to identify the property, the nature of the labor or materials provided, the amount claimed, and the parties involved. Claimants should ensure that all filings comply with the applicable county recording requirements and procedural rules.
