Lorraine Landlord-Tenant Lawyer, New York

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.

A seller's taking advantage of a buyer due to their unequal bargaining positions, perhaps because of the buyer's recent trauma, physical infirmity, ignorance, inability to read or inability to understand the language. The unfairness must be so severe that it is shocking to the average person. It usually includes the absence of any meaningful choice on the part of the buyer and contract terms so one-sided that they unreasonably favor the seller. A contract will be terminated if the buyer can prove unconscionability.

A remedy provided by a court that orders the losing side to perform its part of a contract rather than, or possibly in addition to, paying money damages to the winner.

Laws that limit the amount of rent landlords may charge, and that state when and by how much the rent can be raised. Most rent control laws also require a landlord to provide a good reason, such as repeatedly late rent, for evicting a tenant. Rent control exists in some cities and counties in California, Maryland, New Jersey, New York and Washington, D.C.

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.

Latin for 'that you cause to be done.' This is a court document that instructs a sheriff to seize and sell a defendant's property in order to satisfy a monetary judgment against the defendant.

A tax imposed by a state to compensate for the sales tax lost when an item is purchased outside of the state, but is used within the state. For example, you buy your car in a state that has no sales tax, but you live across the border in a state that does have a sales tax. When you bring your car home and register it in your state, the state taxing authority will bill you for the sales tax it would have collected had you bought the car within the state.

An old-fashioned term for a female executor--the person named in a will to handle the distribution of the deceased person's property. Now, whether male or female, this person is called either the executor or the personal representative.
