The Texas Rule Against Perpetuities is the law that limits the duration of a trust. For years, you could only provide that a trust stretch to “21 years after a life in being.” Generations of law students have scratched their heads over that one. As of 9/1/21, that will change and trusts can now last for 300 years. This is a major game changer in estate planning for middle class and wealthy people. The kicker is that this new rule applies only to trusts formed after 9/1, with some exceptions.  Please review your current trusts and call me if I can assist.
