Supplier pitfalls
Common Supplier Mistakes in Maryland
Missing the 120-day Notice of Lien Claim
Many suppliers fail to send the required preliminary notice early in the project, invalidating their future lien rights.
Filing the lien after 180 days
Waiting too long to file. The deadline is strict and often does not extend for weekends or holidays.
Missing the 1-year enforcement deadline
Filing a lien is not enough; you must enforce it (file a lawsuit) before the enforcement period expires.
