Kentucky Mechanics Lien Form

Mechanics liens are filed against the property that was improved. Filing a claim against real property other than the one where labor and/or materials were furnished would be invalid.

Generally speaking, a mechanics lien is a legal claim for unpaid construction work. Typically, anyone who provides labor or materials to property improvements can file a mechanics lien if they are not paid. 

In regards to who can file a mechanics lien, in general, anyone who makes a permanent improvement to real property can file a mechanics lien. In Kentucky, lien rights are generally pretty expansive, but they don't include everyone. The following parties maintain the right to file a mechanics lien in Kentucky including prime contractors, subcontractors, sub-subcontractors, material suppliers, equipment lessors, and license design professionals. 

If you have fully paid the party in question, there likely won't be a valid mechanics lien claim. 

I am sorry to hear about the frustrating position you are in. To the extent it was truly a bid, it does not sound like it meets the standard of improvement to real property that is necessary for a mechanic's lien. However, bear in mind that architectual services in Maryland do typically qualify for a mechanic's lien so long as something was done onsite, ie, measuring, mapping, etc. So, depending on the precise content of this "bid" and the activities performed by the contractor, it is certainly possible a judge will find that work as qualifing for a mechanic's lien. Consulting with an experienced construction law attorney is your best next step.
