Detailed Explanation

Escrow is a delivery arrangement tied to a future event. In “Definitions and General Terms,” escrow is the placing of an instrument in the hands of a person as a depository who, on the happening of a designated event, is to deliver the instrument to a third person, and the agreement once established should be unalterable. For contrast, a will disposes of property after death, while escrow concerns conditional delivery during life.
