(a) The death of a person who is a conservator of a child is a material and substantial change of circumstances sufficient to justify a temporary order and modification of an existing court order or portion of a decree that provides for the appointment of a conservator or that sets the terms and conditions of conservatorship or for the possession of or access to the child.
(b) Before modifying an order under § 156.101 based on a material and substantial change of circumstances described by Subsection (a), the court must consider any term or condition of the order or portion of a decree that denies possession of the child to a parent or imposes restrictions or limitations on the parent’s right to possession of or access to the child. The court may include those restrictions or limitations in a modification of the order if the court finds that the restrictions or limitations continue to be in the best interest of the child.
