In terms of copyright protection, either the person who creates the work, the person or business that pays another to create the work in an employment context or the person or business that commissions the work under a valid work for hire contract. For example, a songwriter may write a song, but if he is employed by a company to do so, the company is the author of that song for copyright purposes.

Two or more tenants who rent the same property under the same lease or rental agreement. Each co-tenant is 100% responsible for carrying out the rental agreement, which includes paying the entire rent if the other tenant skips town and paying for damage caused by the other tenant.

A right to use another person's real estate for a specific purpose. The most common type of easement is the right to travel over another person's land, known as a right of way. In addition, property owners commonly grant easements for the placement of utility poles, utility trenches, water lines or sewer lines. The owner of property that is subject to an easement is said to be 'burdened' with the easement, because he or she is not allowed to interfere with its use. For example, if the deed to John's property permits Sue to travel across John's main road to reach her own home, John cannot do anything to block the road. On the other hand, Sue cannot do anything that exceeds the scope of her easement, such as widening the roadway.

The basis of a contract. Consideration is a benefit or right for which the parties to a contract must bargain; the contract is founded on an exchange of one form of consideration for another. Consideration may be a promise to perform a certain act -- for example, a promise to fix a leaky roof -- or a promise not to do something, such as build a second story on a house that will block the neighbor's view. Whatever its particulars, consideration must be something of value to the people who are making the contract.

A commercial real estate lease in which the tenant pays a fixed amount of rent per month or year, regardless of the landlord's operating costs, such as maintenance, taxes and insurance. A gross lease closely resembles the typical residential lease. The tenant may agree to a 'gross lease with stops,' meaning that the tenant will pitch in if the landlord's operating costs rise above a certain level. In real estate lingo, the point when the tenant starts to contribute is called the 'stop level,' because that's where the landlord's share of the costs stops.

Personal property that has no physical existence, such as stocks, bonds, bank notes, trade secrets, patents, copyrights and trademarks. Such 'untouchable' items may be represented by a certificate or license that fixes or approximates the value, but others (such as the goodwill or reputation of a business) are not easily valued or embodied in any instrument. Compare tangible property.

A promise that pledges nothing, because it is vague or because the promisor can choose whether or not to honor it. Such promises are not legally binding. For example, if you get a new job and promise to work for three years, unless you resign sooner, you haven't made a valid contract and can resign or be fired at any time.
