Child Custody and Support - As enacted, requires the court to consider any failure to pay child support, rather than failure for a period of three years or more, when making a child custody determination; clarifies that the court may preclude or limit any provisions of a parenting plan if the court finds that a parent has failed to pay child support. - Amends TCA Title 36 and Title 37.

HB 492 modifies Tennessee law to change how courts consider child support payments in custody decisions. It removes the previous requirement that a parent must have failed to pay support for three years or more, instead requiring courts to consider any failure to pay court-ordered child support as a factor. The bill also clarifies that courts may limit or deny parenting plan provisions if a parent has not paid child support. This directly affects parents with outstanding child support obligations and courts making custody or parenting plan rulings under Tennessee Code §§ 36-6-106 and 36-6-406.
