Frequently Asked Questions
Child Support in Tennessee
Discover what you need to know about Child Support Laws in Tennessee.
Tennessee calculates child support under Tennessee Code Annotated § 36-5-101 and the Tennessee Child Support Guidelines, which use an income shares model.
Tennessee estimates what parents would have spent on the child if living together and divides that obligation proportionally based on each parent’s income and parenting schedule.
The calculation generally considers:
Both parents’ gross monthly incomes
The number of children
The Tennessee Basic Child Support Obligation (BCSO) schedule
Parenting time (number of days per year)
Health insurance premiums for the child
Work-related childcare expenses
Extraordinary medical expenses
Other court-approved deviations
Tennessee uses standardized Child Support Worksheets to determine the presumptive support amount.
For an estimate tailored to your situation, you can use the Deliberately.ai child support calculator above—but only a court order is legally binding.
Child support in Tennessee is commonly influenced by:
Each parent’s gross monthly income
The number of children
The Basic Child Support Obligation schedule
The number of parenting days each parent exercises
Health insurance costs for the child
Work-related childcare expenses
Extraordinary medical expenses
Court-approved deviations
Self-employment income, bonuses, commissions, overtime, and variable earnings may require detailed documentation.
There is no universal amount.
The final figure depends on:
Combined parental gross income
The Basic Child Support Obligation schedule
Parenting time adjustment (number of days exercised)
Add-on expenses (childcare, medical, insurance)
Any approved deviation
For a reliable estimate before filing or negotiating, use the Deliberately.ai calculator above—keeping in mind the court has final authority.
In Tennessee, child support generally continues until the child turns 18 years old or graduates from high school, whichever occurs later.
Support may continue until the child turns 19 if still enrolled in high school.
Always review your specific court order for termination terms.
Not necessarily.
Support typically continues until high school graduation if the child is still enrolled.
Wage withholding may continue unless formally terminated.
Any unpaid arrears remain owed even after the obligation period ends.
Termination procedures must follow court requirements.
Yes.
A child support order may be modified when:
There is a significant variance between the existing order and the guideline amount
Either parent’s income changes substantially
Parenting time changes
The guideline calculation produces a different result
Modifications generally apply from the date a petition to modify is filed.
Timeframes depend on:
Whether the case is contested
Court scheduling
Court availability
Whether income documentation is disputed
Uncontested cases may resolve more quickly.
Basic child support is intended to cover:
Housing
Food
Clothing
Transportation
Utilities
Ordinary living expenses
Separate allocations may include:
Health insurance premiums
Unreimbursed or extraordinary medical expenses
Work-related childcare
Educational expenses (when ordered)
It can—but only if:
The expense is included in the guideline calculation, and
The court order reflects the allocation
Paying expenses outside the court order does not automatically reduce the monthly obligation.
Tennessee generally considers gross income, including:
Wages and salary
Bonuses and commissions
Overtime (when consistent)
Self-employment income
Rental or investment income
Unemployment benefits
Disability benefits
Certain allowable adjustments are applied under the Tennessee guidelines.
If a parent is voluntarily unemployed or underemployed, the court may impute income based on earning capacity.
Nonpayment may result in enforcement actions such as:
Wage garnishment
Tax refund intercept
Bank account seizure
Driver’s license suspension
Professional license suspension
Passport denial
Contempt proceedings
Arrears continue accumulating until fully paid.
Arrears generally:
Remain owed until paid in full
May accrue statutory interest
Can be collected through enforcement tools
Do not disappear when the child reaches adulthood
Yes.
Income withholding is common, and the Tennessee Department of Human Services (Child Support Services) may use additional enforcement measures when necessary.
Potentially.
Tennessee applies a parenting time adjustment based on the number of days each parent exercises. More parenting days may reduce the guideline support amount.
However, the Basic Child Support Obligation schedule still controls unless the court approves a deviation.
In limited cases, yes.
If a child has a severe disability that began before adulthood and prevents self-support, courts may consider continued support.
These cases can be legally complex and typically require court involvement.
Parents generally cannot privately override a court order.
Any agreement must be approved by the court to be legally enforceable.
A lawyer is not required for straightforward cases, but it is strongly recommended when:
Income is disputed
Self-employment is involved
Arrears exist
A deviation is requested
Custody is contested
You will typically need:
Recent pay stubs
Federal and state tax returns
Proof of health insurance costs
Childcare expense documentation
Existing court orders
Incomplete documentation can delay proceedings.
Child support cases are typically handled through the Tennessee Juvenile Court or Circuit/Chancery Court, depending on the county. The Tennessee Department of Human Services (Child Support Services) may also assist with establishing and enforcing support.
If income, parenting time, or deviation issues are likely to be contested, consulting a Tennessee family law attorney before filing can help prevent delays and costly mistakes.

How Long Does a Child Support Modification Take in Louisiana?
Michigan calculates child support using the Michigan Child Support Formula (MCSF), which Michigan courts are required to use when setting or changing child support.
Michigan’s approach is based on an income-shares model, meaning the formula estimates what parents would have contributed toward the child if they lived together, then allocates responsibility between parents.
The calculation is based on:
Both parents’ incomes (used to determine each parent’s support share)
Number of children
A statewide support schedule/formula inputs (per MCSF)
Parenting time / overnights (Michigan applies a parental time offset when overnights can be determined)
Medical support (health insurance and ordinary medical considerations)
Work-related childcare expenses
Other adjustments and court-approved deviations under the MCSF
