Arcola Real Estate Lawyer, Illinois

A legal doctrine stating that if a person receives money or other property through no effort of his own, at the expense of another, the recipient should return the property to the rightful owner, even if the property was not obtained illegally. Most courts will order that the property be returned if the party who has suffered the loss brings a lawsuit.

A loan in which the borrower puts up the title to real estate as security (collateral) for a loan. If the borrower doesn't pay back the debt on time, the lender can foreclose on the real estate and have it sold to pay off the loan.

A doctrine that prevents a defendant from re-litigating an issue after it has been lost. For example, if your neighbor sues you for putting up a fence on his land and the court rules that your fence extends beyond your property line, you can't later file your own lawsuit seeking a declaration that the property line is incorrectly drawn.

The power of the federal or state government to take private property for a public purpose, even if the property owner objects. The Fifth Amendment to the United States Constitution allows the government to take private property if the taking is for a public use and the owner is 'justly compensated' (usually, paid fair market value) for his or her loss. A public use is virtually anything that is sanctioned by a federal or state legislative body, but such uses may include roads, parks, reservoirs, schools, hospitals or other public buildings. Sometimes called condemnation, taking or expropriation.

A valid contract in which a copyright owner authorizes another person or entity (called the licensee) to exclusively exercise one or more of the rights (or portion of such rights) that belong to the copyright owner under the copyright. The licensee is said to 'own' the rights granted in the license and is referred to as a copyright owner.

A legal claim placed on real estate by someone who is owed money for labor, services or supplies contributed to the property for the purpose of improving it. Typical lien claimants are general contractors, subcontractors and suppliers of building materials. A mechanics' lien claimant can sue to have the real estate sold at auction and recover the debt from the proceeds. Because property with a lien on it cannot be easily sold until the lien is satisfied (paid off), owners have a great incentive to pay their bills.

An arrangement designed to encourage low-and moderate-income families to purchase housing, in which the housing is offered at an extremely favorable price with a low down payment. The catch is that when the owner sells, she gets none of the profit if the market value of the unit has gone up. Any profit returns to the organization that built the home, which then resells the unit at an affordable price.

An agreement, generally included in an employment contract or a contract for the sale of a business, where one party agrees not to compete with the other party for a specific period of time and within a particular area. Salespeople, for example, often sign noncompetition agreements that prevent them from using the contacts gained by one employer to benefit another employer. Or a salesperson may sign what is known as a 'noncompete,' agreeing not to sell within a particular area, or even work in the same type of business. In some states, such as California, courts view noncompetition agreements with disfavor and will not enforce them unless the restrictions are very narrow. In other states, courts routinely uphold them.
