Uniform Gifts to Minors Act (UGMA)

Definition from Nolo’s Plain-English Law Dictionary

A uniform law, adopted by many states, that allows an adult to give money or securities to a child but have the assets managed by someone of the donor's choosing, called a custodian. The gift is made during the donor's lifetime, not at death. The custodianship ends, and the property goes to the beneficiary outright, at an age set by state law, usually 18 or 21.
