Here, we break down exactly what the state of Maryland requires of you to properly file a valid lien and bond claim.

How to File a Valid Lien in Maryland:

  • To file a lien in Maryland, the amount of work or the construction of the building or buildings being repaired, rebuilt, or improved in the Place 1* contract must be 15% or more of the property’s value. 
  • If materials are delivered to the site, a lien is established even if they are not used at the project.  
  • If materials are picked up by a Contractor for a specific project, that proves a lien unless it can be established that they were not used at the project.
  • For single-family houses, a lien will be limited to the amount of money the Owner has left that is due to the Contractor when they receive the notice of lien.
  • You must send notice of amounts due to the Owner within one hundred and twenty (120) days of your last work and/or materials supplied.
  • A lien can only be established by court order. 
  • You must file a Petition to Establish a Mechanic’s Lien in the Circuit Court in the county where the property is located. This petition must be filed within (180) days of your last work and/or materials supplied. 

How to Have a Valid Bond Claim in Maryland: 

  • Place 4* and above Contractors have bond claim rights on public works projects.
  • Place 3 & 4* Contractors must give notice to the Place 1* Contractor ninety (90) days after the last work done and/or materials supplied.
