The undertutor shall:
(1) Cause the natural tutor to record the legal mortgage in favor of the minor as provided in Article 4134;
(2) Require the tutor to furnish evidence that he has a valid and merchantable title to property offered as security under a special mortgage instead of bond and that the value of the property is at least equal to the amount of security required; otherwise the undertutor shall oppose the tutor's application to furnish a special mortgage; and
(3) Apply to the court for an order compelling the tutor to furnish additional security whenever the security has become insufficient for any reason.
