A paperless method of entering into an electronic contract. To 'sign' a contract electronically, a person may be asked to click an 'I Accept' button or use a 'key' to encrypt (scramble) information that uniquely identifies the signer using a method called Public Key Infrastructure (PKI). Electronic signatures are as binding as those in ink.

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 lump sum cash payment paid by a buyer when he or she purchases a major piece of property, such as a car or house. The buyer typically takes out a loan for the balance remaining, and pays it off in monthly installments over time.

A deed that transfers whatever ownership interest the transferor has in a particular property. The deed does not guarantee anything about what is being transferred, however. For example, a divorcing husband may quitclaim his interest in certain real estate to his ex-wife, officially giving up any legal interest in the property. Compare grant deed.

A type of bond (an interest-bearing document that serves as evidence of a debt) that does not require security in the form of a mortgage or lien on a specific piece of property. Repayment of a debenture is guaranteed only by the general credit of the issuer. For example, a corporation may issue a secured bond that gives the bondholder a lien on the corporation's factory. But if it issues a debenture, the loan is not secured by any property at all. When a corporation issues debentures, the holders are considered creditors of the corporation and are entitled to payment before shareholders if the business folds.

A payment required by a landlord to ensure that a tenant pays rent on time and keeps the rental unit in good condition. If the tenant damages the property or leaves owing rent, the landlord can use the security deposit to cover what the tenant owes.

A rule that allows you to cancel a contract within a specified time period (typically three days) after signing it. Federal cooling-off rules apply this three-day grace period to sales made door-to-door and anywhere other than a seller's normal place of business, such as at a trade show. Another federal cooling-off rule lets you cancel a home improvement loan or second mortgage within three days of signing. Various states have cooling-off rules that sometimes apply even longer cancellation periods to specific types of sales, such as dancing lessons and timeshares.

A rental agreement or lease between a tenant and a new tenant (called a sublessee) who will either share the rental or take over from the first tenant. The sublessee pays rent directly to the tenant. The tenant is still completely responsible to the landlord for the rent and for any damage, including that caused by the sublessee. Most landlords prohibit subleases unless they have given prior written consent. Compare assignment.

An extraordinary and unexpected natural event, such as a hurricane, tornado, earthquake or even the sudden death of a person. An act of God may be a defense against liability for injuries or damages. Under the law of contracts, an act of God often serves as a valid excuse if one of the parties to the contract is unable to fulfill his or her duties -- for instance, completing a construction project on time.
