But I found this Utah Statute.

First my summary. It looks like in Utah an insurance company can pay a settlement of under $10,000 directly to the parents of a minor (who live with the minor) and need not file anything with the court. The parent then has a duty to ONLY use the funds for the support and education of that minor child, and cannot pay themselves except for actual out of pocket expenses AND any excess sums shall be preserved for future support of the minor. Any balance not so used and any property received for the minor must be turned over to the minor when he attains majority.

By way of practicality, a $4,000 settlement is not likely to cause anyone heartburn if the money is lost in a reasonable investment. HOWEVER, best practice would be to put the money in some type of insured, or guaranteed account or you could face problems for violating fiduciary duties.

75-5-102. Facility of payment or delivery.
(1) Any person under a duty to pay or deliver money or personal property to a minor may perform this duty, in amounts not exceeding $10,000 per annum, by paying or delivering the money or property to:
(a) the minor, if he is married or if payment to the minor is expressly authorized by statute;
(b) any person having the care and custody of the minor with whom the minor resides; or
(c) a guardian of the minor.
(2) This section does not apply if the person making payment or delivery has actual knowledge that a conservator has been appointed or proceedings for appointment of a conservator of the estate of the minor are pending.
(3) The persons, other than the minor, receiving money or property for a minor are obligated to apply the money to the support and education of the minor and may not pay themselves except by way of reimbursement for out-of-pocket expenses for goods and services necessary for the minor's support. Any excess sums shall be preserved for future support of the minor. Any balance not so used and any property received for the minor must be turned over to the minor when he attains majority.
(4) Persons receiving money under this section on behalf of a minor shall have the power to settle and release in whole or in part the claims belonging to the minor giving rise to the duty to pay money to the minor.
(5) Persons who pay or deliver in accordance with provisions of this section are not responsible for the proper application thereof.
