How much does it cost to file a mechanics lien?

The recording fee itself is small — typically $15 to $150 depending on the county. The real costs are preparation and service: full-service filing companies commonly charge $95–$345 per document, and attorneys more. Add certified-mail service on the owner (and often the lender and GC), which runs a few dollars per party.

If the lien is ignored and you must enforce (foreclose) it, litigation costs apply — which is why most liens settle: the filing alone usually gets the conversation moving. Preparing the document yourself or with software keeps the cost near the recording fee.
