Let me add my support to M, who is describing the common situation in which a parent pays a minor child to be an employee of the parent’s business. The unusual fact is that the business has a 401(k)-plan permitting deferral and contribution to the plan of part of the child’s compensation. The question is who can make such deferral decision, including what portion of compensation to defer. No State law permits minor children to decide how to dispose of their property. All states have a procedure by which the state courts or a guardian appointed by the court may exercise such power. ERISA has no provision that gives minors or any other individual lacking the capacity the ability to decide how to dispose of such individual’s property. Thus, the plan could not rely on any election executed by the minor or any other individual without capacity
Thus, an ERISA plan must defer to the decision of the child’s guardian or a local court about the extent of the child’s deferral, the investment of the deferrals, or the form of the distributions of the child’s account balance on the termination of employment. Parents need not be their minor child’s guardian, but in practice if there is no marital dispute or parental abuse issue, a child’s parent is often accepted as the child’s guardian without any court appointment.
If an ERISA plan withholds compensation in a manner that is not consistent with the election of the child’s guardian, the consequence would be the same as if it withheld compensation of any employee with capacity without the employee’s consent. In either case, the employee would be entitled to a refund of the wrongful contribution and accrued earnings. If the 401(k) plan had a qualified automatic contribution arrangement the issue would remain because such arrangements must give the employee the right to stop such contributions. This right would be a nullity unless the person with the right to act on behalf of the employee without capacity is timely given such a right. Whether or not the guardian of the individual without capacity seeks a refund in such a case has nothing to do with the tax qualification of the 401(k) plan. If the plan fails to follows its terms that deferrals be made only in accord with employee elections, whether initial or to stop an automatic contribution, the plan is not tax-qualified. There would no such compliance if an employee lacks capacity to make such an election, and the person, if any, with such authority is not given the right to make such election. On the other hand, a timely refund could eliminate the tax-qualification issue.
