Delaware Mechanics Lien Statutes: Deadlines, Venues & Citations
Where Delaware liens are filed and enforced
A Delaware mechanics lien is filed with the Prothonotary (Superior Court) in the county where the project sits — 120 days from last date of furnishing. Filing in the wrong county does not perfect the claim, which matters on projects that straddle county lines. Those are two different clocks against two different offices, and Delaware claimants lose rights far more often by missing the second one than the first.
Delaware deadlines by claimant role

Rules specific to Delaware
