Magalia Eminent Domain Lawyer, California

The many types of information presented to a judge or jury designed to convince them of the truth or falsity of key facts. Evidence typically includes testimony of witnesses, documents, photographs, items of damaged property, government records, videos and laboratory reports. Rules that are as strict as they are quirky and technical govern what types of evidence can be properly admitted as part of a trial. For example, the hearsay rule purports to prevent secondhand testimony of the 'he said, she said' variety, but the existence of dozens of exceptions often means that hairsplitting lawyers can find a way to introduce such testimony into evidence. See also admissible evidence, inadmissible evidence.

A legal claim placed on real estate by someone who is owed money for labor, services or supplies contributed to the property for the purpose of improving it. Typical lien claimants are general contractors, subcontractors and suppliers of building materials. A mechanics' lien claimant can sue to have the real estate sold at auction and recover the debt from the proceeds. Because property with a lien on it cannot be easily sold until the lien is satisfied (paid off), owners have a great incentive to pay their bills.

A provision in a lease that absolves the landlord from responsibility for all damages, injuries or losses occurring on the property, including those caused by the landlord's actions. Most states have laws that void exculpatory clauses in rental agreements, which means that a court will not enforce them.

The legally prescribed time limit in which a lawsuit must be filed. Statutes of limitation differ depending on the type of legal claim, and often the state. For example, many states require that a personal injury lawsuit be filed within one year from the date of injury -- or in some instances, from the date when it should reasonably have been discovered -- but some allow two years. Similarly, claims based on a written contract must be filed in court within four years from the date the contract was broken in some states and five years in others. Statute of limitations rules apply to cases filed in all courts, including federal court.

In the context of U.S. immigration law, people who have been allowed to live in the United States indefinitely to protect them from persecution in their home countries. Refugees get their status before coming to the U.S., while asylum seekers obtain their status after arrival. Refugees may eventually get green cards.

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 legally binding agreement involving two or more people or businesses (called parties) that sets forth what the parties will or will not do. Most contracts that can be carried out within one year can be either oral or written. Major exceptions include contracts involving the ownership of real estate and commercial contracts for goods worth $500 or more, which must be in writing to be enforceable. (See statute of frauds.) A contract is formed when competent parties -- usually adults of sound mind or business entities -- mutually agree to provide each other some benefit (called consideration), such as a promise to pay money in exchange for a promise to deliver specified goods or services or the actual delivery of those goods and services. A contract normally requires one party to make a reasonably detailed offer to do something -- including, typically, the price, time for performance and other essential terms and conditions -- and the other to accept without significant change. For example, if I offer to sell you ten roses for $5 to be delivered next Thursday and you say 'It's a deal,' we've made a valid contract. On the other hand, if one party fails to offer something of benefit to the other, there is no contract. For example, if Maria promises to fix Josh's car, there is no contract unless Josh promises something in return for Maria's services.
