What is one requirement for placing a lien on commercial properties?

To place a lien on commercial properties, there are specific legal requirements that must be met to ensure the lien is valid and enforceable. One critical requirement is that a listing agent or contractor must file for the lien in the appropriate legal manner within a designated timeframe. Filing the lien involves submitting a formal document that outlines the amount owed and the situation that justifies the lien. This process ensures that the claim is officially recognized and can be acted upon in a legal context, which is essential for protecting the rights of those who provided services or incurred costs related to the property.

Other options reference methods or conditions that do not align with the formal legal requirements for filing a lien. For instance, a verbal agreement is generally not sufficient to establish a lien, as it does not create a legally enforceable claim. Additionally, while a minimum charge might be referenced in certain contractual contexts, this is not a standard requirement for lien placement. Lastly, notarization of the agreement is not universally mandated for all liens, although it can lend additional legal weight in some cases. Thus, the requirement for a listing agent to file is the most fitting answer regarding the formal procedure necessary for placing a lien on commercial properties.
