A Tennessee Petition to Modify Child Support is a legal document used to request a change in the court-ordered child support payments for a minor child in the state of Tennessee. The petition can be filed by either the parent paying child support, the parent receiving child support, or the Tennessee Department of Human Services. Depending on the circumstances, there are two types of Tennessee Petition to Modify Child Support: (1) a Petition to Modify Child Support Based on an Increase or Decrease in Income, and (2) a Petition to Modify Child Support Based on a Material Change in Circumstances. The former is used when the petitioner is seeking a modification due to an increase or decrease in income, while the latter is used when the petitioner is requesting a modification due to a material change in circumstances, such as a change in the child's needs or the paying parent's ability to pay. The petition must include specific information about the current child support order, the requested modification, and the reason for the modification. After filing the petition, the court will review the case and issue an order for a new child support payment amount.
