Notice to Owner and Contractor or Subcontractor, If Applicable

The owner's real estate may be sold to satisfy this claim only after a court decides the facts and issues on which it rests. Claimant must bring suit in the Superior Court in the county where the property is located within one year after the last furnishing date, or within 30 days after receiving a qualifying written demand to sue. Failure to bring the action requires forfeiture and discharge of the lien. You will receive notice of the proceeding and may challenge the claim. If a judgment for Claimant is entered and remains unpaid, the owner's real estate may be sold to satisfy it; a judgment against a community association for its contract cannot be enforced by sale of real estate. The owner may instead pay Claimant and obtain a discharge, giving up the right to challenge the claim in court, or discharge the property lien with a surety bond or deposit under N.J.S.A. 2A:44A-31 while retaining that right.

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.
