Waterfall Landlord-Tenant Lawyer, Pennsylvania

The building of a structure entirely or partly on a neighbor's property. Encroachment may occur due to faulty surveying or sheer obstreperousness on the part of the builder. Solutions range from paying the rightful property owner for the use of the property to the court-ordered removal of the structure.

A legal principle or rule created by one or more decisions of a state or federal appellate court. These rules provide a point of reference or authority for judges deciding similar issues in later cases. Lower courts must apply these rules when faced with similar legal issues. For example, if the Montana Supreme Court decides that a certain type of employment contract overly restricts the right of the employee to quit and get another job, all other Montana courts must apply this same rule.

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.

A nonrefundable fee charged by a landlord when a tenant moves in. The fee covers the cost of cleaning the rented premises after you move out, even if you leave the place spotless. Cleaning fees are illegal in some states and specifically allowed in others, but most state laws are silent on the issue. Landlords in every state are allowed to use the security deposit to clean a unit that is truly dirty.

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.

A contract giving written permission to use an invention, creative work or trademark. A license provides a way to make money from your invention or creative work without having to manufacture and sell copies yourself. By licensing an invention or work to a company, you get money (often in the form of royalties) in return for allowing the company to use, produce and sell copies of your invention or work in the marketplace.

A way for two or more people to share ownership of real estate or other property. When two or more people own property as joint tenants and one owner dies, the other owners automatically own the deceased owner's share. For example, if a parent and child own a house as joint tenants and the parent dies, the child automatically becomes full owner. Because of this right of survivorship, no will is required to transfer the property; it goes directly to the surviving joint tenants without the delay and costs of probate.

Funds, usually amounting to one or two months' salary, frequently offered by employers to workers who are laid off. No law compels employers to provide severance pay, although the employer may be legally obligated to do so if it was promised in a contract or employees' handbook.

A right to property that cannot be enforced in the present, but only at some time in the future. For example, John's will leaves his house to his sister Marian, but only after the death of his wife, Hillary. Marian has a future interest in the house.
