A common law lien is a lien that is created due to common law and does not depend on any statute or contract for its existence. Unless abolished by statute or judicial decision, common law liens generally have the force of law in each U.S. state.
In property and real estate law, an improvement is any positive permanent change to land that augments the property’s value. An improvement will cause positive change to the land, increase the value, and will allow the landowner to make productive use of the property. Common examples are adding permanent buildings and other structures, or making an addition to an existing building.
A "kickback" is a term used to refer to a misappropriation of funds that enriches a person of power or influence who uses the power or influence to make a different individual, organization, or company richer. Often, kickbacks result from a corrupt bidding scheme. Through corrupt bidding, the official can award the contract to a company, even though the company did not place the lowest bid. The company profits by having been awarded the bid and getting to perform the contract.
Labor and materials (time and materials) refers to a type of contract under which a customer agrees to pay a contractor for the actual cost of labor and materials used to complete a project, plus an agreed-upon markup or fee. Instead of setting a total price in advance, the contract compensates the contractor based on the time spent and the materials supplied.
