Welcome to NACM's Secured Transaction Services (STS), providing credit professionals with Mechanic's Lien and Bond Services and UCC filing services. NACM's STS prepares, serves, files, and enforces preliminary notices and mechanic's liens and payment bond claims on a nationwide basis.

STS offers services on two levels: a construction filing service utilizing a nationwide attorney network and an internally prepared notice to owner service. The construction filing service is comprised of experienced construction-oriented attorneys who prepare, serve, file, and enforce preliminary notices, liens, and bond claims. Our attorney network's vast knowledge and expertise ensures that all requests are completed professionally, accurately, and quickly. The internally prepared notice to owner service offers a more cost-effective option for smaller receivable balances, non-statutory notices, or situations where there is confidence in job information.

Both preliminary notice filing options include, at no additional charge, a next action notification email. These reminders are sent automatically to ensure that you will never miss a lien and suit deadline.

In addition to these services, NACM's STS also provides an online Lien Navigator, specifically developed for credit professionals, that provides step-by-step time frames for all 50 states, D.C., and the Canadian provinces. The Lien Navigator contains links to statute references, quick list sections, and "Speed Bump" warnings — cautioning users of nuances in the law. With a Miller Act section, public bond thresholds and values, and a robust glossary, the Lien Navigator serves as a comprehensive guide accessible 24/7.
