Child Support in Tennessee
Tennessee uses the income shares model to calculate child support. This model appears in the Tennessee Child Support Guidelines, found at Tennessee Comprehensive Rules and Regulations chapter 1240-02-04. The guideline adds both parents' gross incomes together and applies a statewide schedule to that combined total. It then splits the resulting obligation between the parents, based on each parent's share of the combined income. Parenting time factors into the calculation as an adjustment. A Tennessee support order can come out of a circuit, chancery, or juvenile court case, depending on the type of proceeding. A parent can also apply through Tennessee Child Support Services, part of the Department of Human Services. This agency serves as the state's IV-D agency. The right court depends on the circumstances. Courts typically decide divorce-related support in circuit or chancery court. Juvenile court often handles paternity cases and standalone IV-D support matters.

The Tennessee income shares guideline
Tennessee's guideline appears in chapter 1240-02-04 of the state's administrative rules. It combines both parents' gross incomes, then finds the basic obligation the statewide schedule assigns to that combined amount. It then divides the obligation between the parents in proportion to their income share.
The guideline also includes a parenting time adjustment. This changes the calculation based on how many days each parent spends with the child. Add-ons cover health insurance premiums and work-related child care costs.
Applying through Tennessee Child Support Services
Tennessee Child Support Services operates inside the Department of Human Services. It serves as the state's IV-D agency. A parent can apply through the department's website for paternity establishment, a support order, or enforcement.
A parent already involved in a circuit, chancery, or juvenile court case about children can also have support decided directly within that case.
Which court hears the case
Courts generally decide divorce-related support in circuit or chancery court. Juvenile court commonly handles paternity establishment and standalone support cases, including many opened through Child Support Services.
A parent unsure which court applies should check with Child Support Services or the county court clerk before filing.
Modifying a Tennessee order
A Tennessee order can be modified when a significant variance exists between the existing order and what the current guideline would produce with updated incomes. That variance threshold is itself part of the modification standard. A parent does not necessarily need to show a separate life event on top of it.
To seek modification, a parent files with the court that issued the order, or requests a review through Child Support Services for agency-managed cases.
Enforcement
Tennessee Child Support Services enforces orders using standard IV-D tools. These include income withholding, intercepting state and federal tax refunds, credit bureau reporting, and license suspension for significant arrears.
A parent owed support and needing enforcement help can open a case with the agency. This works even when the original order came from a private court filing.
