If a guardian nominated by a minor who has attained the age of fourteen (14) years is not approved by the court or if, after being notified by the court, the minor neglects for ten (10) days to nominate a suitable person, the court may name and appoint a guardian in the same manner as if the minor was under the age of fourteen (14) years.
