Berne Real Estate Lawyer, Switzerland

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 statute, adopted by almost all states, that provides a method for transferring property to minors and arranging for an adult to manage it until the child is old enough to receive it. See custodian.

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 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.

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.

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.

The process of filing a copy of a deed or other document concerning real estate with the land records office for the county in which the land is located. Recording creates a public record of changes in ownership of all property in the state.

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 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.
