Tennessee Custody Laws: PRP, ARP, and How Custody Actually Works

If you're searching for "custody laws in Tennessee," here's the first thing you need to know: Tennessee doesn't actually use the word "custody" in its statutes anymore.

In 2001, the Tennessee General Assembly replaced traditional custody language with a framework built around parenting responsibilities and parenting time. The goal was to reduce conflict by shifting the focus from "winning custody" to building a detailed plan for how both parents stay involved in their child's life.

PRP and ARP: Tennessee's Custody Designations

Instead of "custodial parent" and "non-custodial parent," Tennessee uses two designations:

Primary Residential Parent (PRP) — the parent with whom the child lives more than 50% of the year (183 days or more). This parent's address determines school enrollment and serves as the child's legal residence.

Alternative Residential Parent (ARP) — the parent who exercises parenting time for the remaining days (182 or fewer).

Even in a perfectly equal 50/50 schedule where both parents have 182.5 days, the court still requires one parent to be designated as PRP. This isn't about who's more important — it's a federal tax and administrative requirement.

Decision-Making Authority Is Separate from Residential Time

Here's where most parents get confused: having less residential time doesn't mean you lose your say in major decisions.

Tennessee divides decision-making authority into four categories:

• Education — school enrollment, tutoring, special education
• Healthcare — medical, dental, and mental health decisions
• Extracurricular activities — sports, clubs, camps
• Religious training — church, religious education

Each category can be assigned to one parent exclusively, shared jointly, or divided so each parent controls different areas. An ARP with every-other-weekend parenting time can still share equal decision-making authority on all four topics.

How Judges Decide Custody Arrangements

When parents can't agree, judges evaluate the arrangement using 15 statutory best-interest factors under T.C.A. § 36-6-106(a). Key factors include:

• Which parent has historically handled daily caregiving (feeding, homework, bedtime routines)
• Each parent's willingness to encourage a close relationship with the other parent
• The stability of each parent's home environment
• The child's existing school and community connections
• The child's reasonable preference (given weight at age 12 and older)

Tennessee law explicitly prohibits gender-based presumptions — mothers and fathers start on equal legal footing.

The Permanent Parenting Plan Requirement

Every divorce or custody case involving minor children in Tennessee must include a court-approved Permanent Parenting Plan. This isn't optional — the case cannot be finalized without one.

The plan must include a detailed residential schedule (weekdays, weekends, holidays, summer breaks), specific pick-up and drop-off times, decision-making allocations, child support calculations, and a dispute resolution process for future disagreements.

For couples pursuing an agreed divorce on irreconcilable differences grounds, both parties must agree on every element of the parenting plan before filing. Any unresolved issue shifts the case to a contested track, triggering mandatory mediation.

The Court Process Timeline

Filing for custody in Tennessee follows a structured path: file the complaint in Circuit or Chancery Court (filing fees run $250–$350 depending on the county), serve the other parent, complete the mandatory four-hour parenting education seminar, attend mediation if any issues are contested, and present the finalized parenting plan for judicial approval.

Cases with minor children have a mandatory 90-day waiting period before the divorce can be finalized.

Building a Parenting Plan That Works

The parenting plan is the single most important document in a Tennessee custody case. Getting the residential schedule right affects everything downstream — from child support calculations (which use exact parenting-day counts) to how holidays and school breaks are divided.
