Insurance policies are called because the insurer only performs the promised action if a specified chance event occurs.

The answer is aleatory contract. This a type of contract in which the parties involved do not have to accomplish a particular action until a precise event take place. Events are those which cannot be controlled by either party, such as natural disasters and death. Also, an aleatory contract is a contract where the interchange is uneven. The most typical kind of aleatory contract is an insurance policy. Such an insurance contract may be a prosperous to one party but make a major loss for the other, as more in benefits may be paid out than actual premiums received, or vice versa.
