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.

SB 540 amends Tennessee law to change how courts consider child support payments in custody cases. It removes the previous requirement that courts only address nonpayment after three years of failure, instead requiring judges to consider *any* failure to pay court-ordered child support when making custody decisions. The bill also allows courts to restrict or limit parenting plan provisions if a parent has failed to pay child support. This affects parents who miss payments and judges handling custody cases under Tennessee Code Sections 36-6-106 and 36-6-406. The law became effective May 2, 2025.
