Ben Lomond Landlord-Tenant Lawyer, California

An unforeseen and uncontrollable event that excuses a party to a contract from performing his or her duties under that contract. For example, a landlord can break a lease if the property she agreed to rent accidentally burns down before the tenants move in.

A large final payment due at the end of a loan, typically a home or car loan, to pay off the amount your monthly payments didn't cover. Many states prohibit balloon payments in loans for goods or services that are primarily for personal, family or household use, or require the lender to let you refinance the balloon payment before forcing collection.

The terms of your contract with an airline after you buy a ticket. Conditions of carriage cover everything from baggage limitations to the amount of compensation you can recover if you're injured on the flight. These provisions often vary from airline to airline. A few, but by no means most, conditions of carriage appear in the fine print on the back of your ticket. To find out about the rest, you can ask the airline for a copy; it is legally obligated to provide one. The conditions of carriage contain a lot of fine print detail and will not make for exciting reading.

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.

A law adopted by some cities or towns with desirable vistas -- such as those in the mountains or overlooking the ocean -- that protects a property owner from having his or her view obstructed by growing trees. View ordinances don't cover buildings or other structures that may block views.

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.
