Recording and enforcing a Maryland lien
Recording the lien
Record with the circuit court clerk for the county. Electronic recording is available in participating counties. No notary is required on the lien itself. The lien claim must be verified by the claimant.
After recording
Maryland does not require a separate notice after the lien is recorded, though most claimants send one anyway to prompt payment. To keep the lien alive it must be enforced by lawsuit within 1 year after the lien is recorded.
Wrongful lien exposure
Maryland has no dedicated wrongful-lien penalty statute, but an inflated or baseless lien can still be challenged and removed at the claimant's expense.
Practitioner notes for Maryland
Subcontractor notice: subcontractor is not entitled to a lien unless, within 120 days after doing the work or furnishing materials, it gives the owner written notice of intention to claim a lien (Md. Code, Real Prop. §9-104(a)(1)); for owner-occupied single-family residence, lien is barred if owner made full payment to contractor before receiving the notice (§9-104(a)(2)). Petition deadline: file proceedings (petition to establish mechanic’s lien) in the circuit court within 180 days after the work has been finished or materials furnished (Real Prop. §9-105(a)). Enforcement: right to enforce a lien established expires 1 year from the day the petition to establish lien was first filed (Real Prop. §9-109) — this sheet uses enforcement_trigger=lien_recorded_date as proxy for petition filing date.
Statutory sources: Md. Code, Real Prop. §§ 9-104, 9-105, 9-109. Read the Maryland lien statute.
