This law section addresses nonvested property interests, which are future property rights. For these interests to be valid, they must either be set to become definite no later than 21 years after the death of someone alive when the interest is created, or they must become definite or end within 90 years of being established.

This law section explains when a general power of appointment, which can't currently be used because of some required condition that hasn't been met, is considered valid. It will be valid if, at the time it was made, the condition will definitely be met or become impossible no later than 21 years after the death of someone alive at that time. Alternatively, it is valid if the condition is met or becomes impossible within 90 years after the power is created.

This law says that certain powers of appointment, which are legal abilities to designate who will receive property, are not valid unless they meet specific timing rules. There are two main conditions: either the power must be expected to be used or end within 21 years after someone's death, or it must be used or end within 90 years after it's created.

This law states that when deciding if a future interest in property or a power to control property is valid, we don't consider the unlikely event of a child being born after the person has died.

This law outlines how to determine the validity of certain provisions in a trust or property arrangement. Specifically, it states that any part of a trust that attempts to prevent or delay the transfer of a property interest for longer than 21 years after the death of the last living person specified when the trust was created is invalid. This law applies to any trust document made on or after January 1, 1992.
