Miramonte Landlord-Tenant Lawyer, California

The causing of harm by disrupting something that belongs to someone else -- for example, interfering with a contractual relationship so that one party fails to deliver goods on time.

A contract in which an owner leases her house (usually for one to five years) to a tenant for a specific monthly rent, and which gives the tenant the right to buy the house at the end of the lease period for a price established in advance. A lease option is often a good arrangement for a potential home buyer because it lets him move into a house he may buy without having to come up with a down payment or financing at that time.

A lawsuit brought by two parties, not as adversaries, but as collaborators in order to resolve a legal question that affects them both. For example, two companies might bring a friendly suit to court in order to clarify a legal interpretation of a contract between them.

A non-court procedure for resolving disputes using one or more neutral third parties -- called the arbitrator or arbitration panel. Arbitration uses rules of evidence and procedure that are less formal than those followed in trial courts, which usually leads to a faster, less-expensive resolution. There are many types of arbitration in common use: Binding arbitration is similar to a court proceeding in that the arbitrator has the power to impose a decision, although this is sometimes limited by agreement -- for example, in 'hi-lo arbitration' the parties may agree in advance to a maximum and minimum award. In non-binding arbitration, the arbitrator can recommend but not impose a decision. Many contracts -- including those imposed on customers by many financial and healthcare organizations -- require mandatory arbitration in the event of a dispute. This may be reasonable when the arbitrator really is neutral, but is justifiably criticized when the large company that writes the contract is able to influence the choice of the arbitrator.

Principles of international law so fundamental that no nation may ignore them or attempt to contract out of them through treaties. For example, genocide and participating in a slave trade are thought to be jus cogens.

A type of bond (an interest-bearing document that serves as evidence of a debt) that does not require security in the form of a mortgage or lien on a specific piece of property. Repayment of a debenture is guaranteed only by the general credit of the issuer. For example, a corporation may issue a secured bond that gives the bondholder a lien on the corporation's factory. But if it issues a debenture, the loan is not secured by any property at all. When a corporation issues debentures, the holders are considered creditors of the corporation and are entitled to payment before shareholders if the business folds.

A meeting of the minds. An agreement is made when two people reach an understanding about a particular issue, including their obligations, duties and rights. While agreement is sometimes used to mean contract -- a legally binding oral or written agreement -- it is actually a broader term, including understandings that might not rise to the level of a legally binding contract.
