Maryland Lien Deadlines for Material Suppliers
Maryland uses proceedings in circuit court to establish a mechanics lien. Confirm eligibility and any subcontractor notice before treating a filing or payment record as protection.
Public date calculations cover Florida and Kansas. Maryland dates require qualified review.
Risk context
Maryland is High Risk for Suppliers
Maryland is a court-petition process, not a county-recorder lien form. Keep the notice, petition to establish the lien and enforcement step separate. Claimant classification and qualifying dwelling/payment facts also matter. § 9-102 distinguishes erection from repairs, rebuilding or improvements reaching 15 percent of building value, and protects a qualifying bona fide purchaser before lien establishment. Confirm eligibility and property-transfer facts before relying on the timing table.

| Deadline Type | Timing | Details |
|---|---|---|
| Lien Filing Deadline | Proceedings within 180 days after work is finished or materials furnished | File the petition, affidavit and supporting papers with the circuit court clerk for the county where the land or part lies. The clerk dockets an equity proceeding (Real Property § 9-105). |
| Enforcement Deadline | 1 year from the first petition to establish the lien | File the enforcement petition in the lien proceeding within that period. A timely petition preserves the right/lien through the proceeding, subject to the decree (§ 9-109). |
| Subcontractor Notice | Within 120 days after work or furnishing | Give the prescribed written notice to the owner by registered or certified mail with return receipt requested, or personal delivery. Posting has separate absence/other-cause and witness requirements. A single-family dwelling erected on the owner's land for the owner's residence has full-payment and unpaid-balance limits; do not apply a residential label alone (§ 9-104). |

Supplier pitfalls
Common Supplier Mistakes in Maryland
Missing the 120-day Notice of Lien Claim
Establish whether the claimant falls under § 9-104 and retain the prescribed notice, recipient and service evidence. For a qualifying owner-residence dwelling, review owner payments and the balance when notice was given.
Filing the lien after 180 days
Prepare the court petition and supporting evidence before the 180-day period ends. Recorder submission does not substitute for filing proceedings in circuit court. Obtain specific review of disputed triggering and boundary dates.
Missing the 1-year enforcement deadline
Filing a lien is not enough; you must enforce it (file a lawsuit) before the enforcement period expires.

Common questions
Frequently Asked Questions
Do I record a Maryland lien with the county recorder?
Section 9-105 requires proceedings in circuit court, started by filing a petition, affidavit and supporting papers with the clerk. A recorder filing is not that process.
Does every residential supplier have the same notice protection?
No. Section 9-104 addresses subcontractor notice and adds payment-related conditions for a single-family dwelling erected on the owner's land for the owner's residence. Confirm classification and the actual property and payment facts.
Does establishing the lien finish enforcement?
No. Section 9-109 measures the enforcement period from the first petition to establish the lien and requires a timely enforcement petition. Keep that court-process deadline separate from the calculator's notice/lien outcomes.
