Maryland Mechanics Lien — Deadlines, Laws, and Filing Guide
Maryland mechanics lien law is governed by Maryland Code Real Property Title 9. Maryland has a 180-day filing deadline and a unique court petition process that does not exist in any other state. Instead of filing directly with a county recorder, Maryland contractors must petition the circuit court to establish the lien. This guide covers Maryland lien rights in 2026.
Maryland Mechanics Lien Deadline
In Maryland, the deadline to petition the court to establish a mechanics lien is 180 days from the last date of furnishing labor or materials under Maryland Code Real Property Section 9-105. This 180-day deadline applies to all lien claimants. While 180 days is longer than most states, the court petition process takes additional time so early action is critical.
Maryland Unique Court Petition Process
Maryland is unique among all 50 states — instead of filing a lien directly with the county recorder, contractors must petition the circuit court to establish the lien. The court then determines whether the lien is valid and orders it recorded against the property title. No other state requires this court petition process.
Maryland Lien Enforcement Deadline
After the Maryland circuit court establishes the mechanics lien, the claimant must enforce it within 1 year of the court's order. The enforcement timeline runs from when the court establishes the lien — not from when the petition was filed.
Where to File a Mechanics Lien in Maryland
In Maryland, mechanics lien petitions are filed with the circuit court in the county where the project property is located. Major filing courts include Baltimore City Circuit Court, Montgomery County Circuit Court, and Prince George's County Circuit Court.
