Tennessee Code Title 36. Domestic Relations § 36-5-102

(a) In cases where the court orders alimony or child support in accordance with §§ 36-5-101 and 36-5-121, the court may decree to the spouse who is entitled to such alimony or child support such part of the other spouse's real and personal estate as it may think proper. In doing so, the court may have reference and look to the property that either spouse received by the other at the time of the marriage, or afterwards, as well as to the separate property secured to either by marriage contract or otherwise.

(b) In addition to child support, a judge may require the noncustodial adult parent, who is not the legal spouse of the custodial parent, to pay an amount for the maintenance and support of the custodial parent if the custodial parent of the child is a minor. Such amount shall be determined by the court based on the noncustodial parent's ability to pay and shall be in addition to any court-ordered child support. Any order requiring the noncustodial parent to pay an additional amount for the maintenance and support of the custodial parent shall continue to be effective after the custodial parent reaches eighteen (18) years of age if the custodial parent is in high school. Such order shall continue until the custodial parent marries or graduates from high school or until the class of which the custodial parent is a member when the custodial parent attains eighteen (18) years of age graduates, whichever occurs first. As used in this subsection (b), “maintenance and support of the custodial parent” may also include counseling and other special medical services needed by the custodial parent.
