☐ If required, send § 142.6 Pre-Lien Notice before lien filing and within 75 days after last supply by a method supporting the statutory presumption; retain proof.
☐ Identify and verify owner of record, legal description, parcel number, and senior encumbrances via title search.

Real estate documents transfer ownership, define who can use a property, and record agreements between buyers, sellers, landlords, and tenants. Deeds, purchase agreements, leases, and easements have to be drafted to meet state recording requirements, and mistakes show up at closing or years later in title disputes. Good real estate paperwork moves transactions forward quickly and avoids the kind of problems that only surface when it is time to sell or refinance.
