Child Custody Factors TCA 36-6-106
(a) In a suit for annulment, divorce, separate maintenance, or in any other proceeding requiring the court to make a custody determination regarding a minor child, the determination shall be made on the basis of the best interest of the child. In taking into account the child’s best interest, the court shall order a custody arrangement that permits both parents to enjoy the maximum participation possible in the life of the child consistent with the factors set out in subdivisions (a)(1)-(10), the location of the residences of the parents, the child’s need for stability and all other relevant factors. The court shall consider all relevant factors, including the following, where applicable:
(1) The love, affection and emotional ties existing between the parents or caregivers and the child;
(2) The disposition of the parents or caregivers to provide the child with food, clothing, medical care, education and other necessary care and the degree to which a parent or caregiver has been the primary caregiver;
(3) The importance of continuity in the child's life and the length of time the child has lived in a stable, satisfactory environment; provided, that, where there is a finding, under subdivision (a)(8), of child abuse, as defined in § 39-15-401 or § 39-15-402, or child sexual abuse, as defined in § 37-1-602, by one (1) parent, and that a nonperpetrating parent or caregiver has relocated in order to flee the perpetrating parent, that the relocation shall not weigh against an award of custody;
(4) The stability of the family unit of the parents or caregivers;
(5) The mental and physical health of the parents or caregivers;
(6) The home, school and community record of the child;
(7) (A) The reasonable preference of the child, if twelve (12) years of age or older;
(B) The court may hear the preference of a younger child on request. The preferences of older children should normally be given greater weight than those of younger children;
(8) Evidence of physical or emotional abuse to the child, to the other parent or to any other person; provided, that, where there are allegations that one (1) parent has committed child abuse, as defined in § 39-15-401 or § 39-15-402, or child sexual abuse, as defined in § 37-1-602, against a family member, the court shall consider all evidence relevant to the physical and emotional safety of the child, and determine, by a clear preponderance of the evidence, whether such abuse has occurred. The court shall include in its decision a written finding of all evidence, and all findings of facts connected to the evidence. In addition, the court shall, where appropriate, refer any issues of abuse to the juvenile court for further proceedings;
(9) The character and behavior of any other person who resides in or frequents the home of a parent or caregiver and the person's interactions with the child; and
(10) Each parent's or caregiver's past and potential for future performance of parenting responsibilities, including the willingness and ability of each of the parents and caregivers to facilitate and encourage a close and continuing parent-child relationship between the child and both of the child's parents, consistent with the best interest of the child.
(b) Notwithstanding the provisions of any law to the contrary, the court has jurisdiction to make an initial custody determination regarding a minor child or may modify a prior order of child custody upon finding that the custodial parent has been convicted of or found civilly liable for the intentional and wrongful death of the child's other parent or legal guardian.
(c) As used in this section, "caregiver" has the meaning ascribed to that term in § 37-5-501.
(d) Nothing in subsections (a) and (c) shall be construed to affect or diminish the constitutional rights of parents that may arise during and are inherent in custody proceedings.
