The right of a property owner or tenant to enjoy his or her property without interference. Disruption of quiet enjoyment may constitute a nuisance. Leases and rental agreements often contain a 'covenant of quiet enjoyment,' expressly obligating the landlord to see that tenants have the opportunity to live undisturbed.

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 way for married couples to hold title to property, available in Arizona, California, Nevada, Texas and Wisconsin. It allows one spouse's half-interest in community property to pass to the surviving spouse without probate.

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 way two or more people can own property together. Each can leave his or her interest upon death to beneficiaries of his choosing instead of to the other owners, as is required with joint tenancy. In some states, two people are presumed to own property as tenants in common unless they've agreed otherwise in writing.

A commercial real estate lease in which the tenant regularly pays not only for the space (as he does with a gross lease) but for a portion of the landlord's operating costs as well. When all three of the usual costs--taxes, maintenance and insurance--are passed on, the arrangement is known as a 'triple net lease.' Because these costs are variable and almost never decrease, a net lease favors the landlord. Accordingly, it may be possible for a tenant to bargain for a net lease with caps or ceilings, which limits the amount of rent the tenant must pay. For example, a net lease with caps may specify that an increase in taxes beyond a certain point (or any new taxes) will be paid by the landlord. The same kind of protection can be designed to cover increased insurance premiums and maintenance expenses.

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 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.
