I'm sorry to hear about that. First, it's important to understand whether the notice is indicating that a lien has been filed, or whether the notice is merely a warning or threat of lien (such as a Notice of Intent to Lien). How to respond to either situation will vary, and here are some great resources for either situation: (1) I Received a Notice of Intent to Lien - What Should I Do Now?
; and (2) A Mechanics Lien Was Filed On My Property - What Do I Do Now?
Further, it's worth noting that in order for lien rights to arise, there must generally be some permanent improvement to real property. So, where the "work" giving rise to a lien claim has done nothing to improve the property, lien rights will likely not arise, and a lien filed for that work would very likely be considered invalid and unenforceable. When an improper mechanics lien claim is filed, a property owner can challenge the filed lien in order to have it removed from the property. But, in terms of actually preventing
a lien filing in the first place, that might not be so easy. An owner could secure a bond in order to protect their lien from a lien claim, or they could bond off
an already filed lien, but mechanics lien bonds can be expensive. Alternatively, sending a demand letter which informs a contractor of the flaws with their lien claim/potential lien claim could help, especially when coupled with legal threats and sent via an attorney. But when a mechanics lien has been filed, it's wise to consult a local construction or real estate attorney. Mechanics liens are a drastic, powerful remedy, and an attorney will be able to review your situation, advise on how to proceed, and navigate whichever route is taken.
