In its first opportunity to consider the role of trusts for the benefit of adult, unemancipated, disabled children of divorce, the New Jersey Supreme Court said judges should not reject such arrangements out of hand if created for the children’s best interests.

Though affirming two lower courts that held a proposed special-needs trust — for a 25-year-old autistic son living in a group home — lacked sufficient detail on how it would be in his best interests, the justices allowed another chance to prove it and enunciated guidelines.
