Delaware Construction Lien FAQ

You must file a Delaware mechanics lien within 90 days of your last furnishing of labor, materials, equipment, or professional services to the project. This deadline is strictly enforced. The clock starts running from the last day you performed meaningful, contract-related work—not from the date payment was due or negotiations ended.

No. Delaware does not require subcontractors, suppliers, or any other lien claimants to send a preliminary notice, notice to owner, or notice of intent before filing a mechanics lien. Delaware relies instead on short filing and enforcement deadlines to protect property owners.

Delaware grants mechanics lien rights to:

• General contractors

• Subcontractors

• Sub-subcontractors

• Material suppliers

• Equipment rental companies

• Laborers

• Architects, engineers, surveyors, and other design professionals

If you miss the 90-day deadline, you permanently lose your mechanics lien rights. Delaware courts do not allow extensions, grace periods, or equitable exceptions, even if the owner clearly owes the money.

A Delaware mechanics lien is filed with the Prothonotary of the Superior Court in the county where the property is located. Unlike many states, Delaware liens are filed in the court system, not with a recorder of deeds or land records office.

A Delaware mechanics lien must include:

• Claimant’s legal name and address

• Property owner’s name

• Hiring party’s name

• Legal description of the property

• Description of labor, materials, equipment, or services provided

• Amount claimed as due and unpaid

• Date of last furnishing

• Verification or sworn statement

No. Delaware law does not impose a minimum or maximum lien amount. However, the lien must reflect only the amount actually owed after all credits and payments. Intentionally overstating a lien can expose the claimant to damages or invalidate the lien.

Yes. Multiple contractors, subcontractors, suppliers, or design professionals may each file separate mechanics liens against the same property if they independently provided work or materials and were not paid. Each lien stands on its own based on compliance with the statute.

If the customer pays you the full amount owed after you have recorded a lien, you have a legal obligation to formally clear the lien from the property records.

You must prepare and file a Delaware Discharge of Lien (or Release of Lien) with the same office where the original lien was recorded.
