Malvern Real Estate Lawyer, Pennsylvania

A legal doctrine that requires landlords to offer and maintain livable premises for their tenants. If a landlord fails to provide habitable housing, tenants in most states may legally withhold rent or take other measures, including hiring someone to fix the problem or moving out. See constructive eviction.

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.

A statement included in a patent application that describes the structure of an invention in precise and exact terms, using a long established formal style and precise terminology. Patent claims serve as a way for the U.S. Patent and Trademark Office (PTO) to determine whether an invention is patentable, and as a way for a court to determine whether a patent has been infringed. In concept, a patent claim marks the boundaries of the patent in the same way as the legal description in a deed specifies the boundaries of the property.

A proposal to enter into an agreement with another person. An offer must express the intent of the person making the offer to form a contract, must contain some essential terms--including the price and subject matter of the contract--and must be communicated by the person making the offer. A legally valid acceptance of the offer will create a binding contract.

A gift of property. The IRS allows you to take an income tax deduction for the value of donations made to charitable organizations who are recognized as such by the IRS.

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 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 determination of the value of something, such as a house, jewelry or stock. A professional appraiser -- a qualified, disinterested expert -- makes an estimate by examining the property, and looking at the initial purchase price and comparing it with recent sales of similar property. Courts commonly order appraisals in probate, condemnation, bankruptcy or foreclosure proceedings in order to determine the fair market value of property. Banks and real estate companies use appraisals to ascertain the worth of real estate for lending purposes. And insurance companies require appraisals to determine the amount of damage done to covered property before settling insurance claims.

When a landlord provides housing that is so substandard that a landlord has legally evicted the tenant. For example, if the landlord refuses to provide heat or water or refuses to clean up an environmental health hazard, the tenant has the right to move out and stop paying rent, without incurring legal liability for breaking the lease.
