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.

Wrongful lien exposure

We found no dedicated wrongful-lien penalty in Maryland's lien statute. An owner can still ask a court to remove an inflated or baseless lien, so claim only what you are owed.

Practitioner notes for Maryland

Maryland is unusual: a mechanic's lien is established through a lawsuit, not by recording a document. A subcontractor or supplier who did not contract with the owner must first give the owner a written notice of intention to claim a lien within 120 days after doing the work or furnishing the materials. Send it by registered or certified mail, return receipt requested, or deliver it in person. If the owner cannot be reached, it may be posted on the building before a witness (Md. Code, Real Prop. § 9-104). On a single-family home being built on the owner's land for the owner's own residence, a subcontractor has no lien if the owner paid the contractor in full before getting the notice, and on that kind of home the lien is limited to what the owner still owed when notified. Every claimant must then file a petition to establish the lien in the circuit court for the county where the land is located, within 180 days after the work was finished or the materials furnished. The petition must include a supporting affidavit and copies of the key documents (Md. Code, Real Prop. § 9-105). The court reviews the petition and orders the owner to show cause why the lien should not attach. It may require the claimant to post a bond against the owner's damages (Md. Code, Real Prop. § 9-106). The right to enforce an established lien expires one year after the petition was first filed unless a petition to enforce is filed in that case (Md. Code, Real Prop. § 9-109). Attorneys must file electronically through the state court system. Because this is a court proceeding with strict pleading rules, confirm with counsel.
