Shared Custody in Louisiana: The 2026 Equal Time Mandate

Louisiana's custody landscape shifted on August 1, 2026, when Act 605 changed a single word in the statute — and that word changed everything. La. R.S. 9:335(A)(2)(b) previously said physical custody should be shared equally when joint custody is ordered. Now it says shall.

That one-word change means 50/50 shared physical custody is the mandatory default in every joint custody case. If you're going through a custody dispute in Louisiana right now, here's what that actually means in practice.

What "Shared Custody" Means Under Louisiana Law

Louisiana distinguishes between shared physical custody and joint physical custody — and the difference directly affects your child support calculation and your daily life.

Shared custody means each parent has the child for approximately equal overnights per year. "Approximately" matters — courts don't require a mathematically perfect 182.5/182.5 split. A schedule that gives each parent 45-55% of overnights generally qualifies.

Under the 2026 mandate, a judge must order this 50/50 split unless one parent proves that equal time isn't logistically feasible — different school districts, extreme distance between homes, work schedules that make midweek exchanges impossible — or that it's contrary to the child's best interests under the Article 134 factors.

Common 50/50 Schedules in Louisiana

Three schedules dominate Louisiana shared custody arrangements:

Alternating weeks (week-on/week-off). The child spends one full week with each parent. Best for school-aged children when both parents live in the same school district. The downside: seven consecutive days away from one parent can be hard on younger children.

2-2-3 rotation. The child spends 2 days with Parent A, 2 days with Parent B, then 3 days with Parent A — and the pattern flips the following week. This keeps maximum contact frequency but requires parents who can handle multiple exchanges per week without conflict. Best for toddlers and preschoolers.

Alternating weekends with midweek overnight. Technically closer to 60/40, but some parishes accept a modified version (alternating weekends plus two midweek overnights) as qualifying for shared custody under Worksheet B. The arrangement works for higher-conflict situations because it reduces exchange frequency.

Your parenting plan must also account for Louisiana-specific holidays. Mardi Gras is treated as a major alternating holiday in most JDC plans — typically Friday before Mardi Gras through Wednesday morning when school resumes. Hurricane evacuation provisions are mandatory under R.S. 9:335(A)(2)(c).

How Shared Custody Affects Child Support

The financial impact of shared vs. joint custody is significant. Under Louisiana's Income Shares model (La. R.S. 9:315), shared custody triggers Worksheet B, which accounts for both parents' direct spending during their custodial time.

Under Worksheet B, a parent earning $5,000/month with two children might pay substantially less in support than under Worksheet A for a 70/30 arrangement — because the calculation recognizes that both parents are already covering the child's daily expenses during their custodial periods.

This financial difference is one reason custody disputes in Louisiana can become contentious. The shift from a 60/40 schedule to a true 50/50 schedule can change which worksheet applies and reduce or increase the support obligation by hundreds of dollars per month.

The Domiciliary Parent Still Matters

Even in a perfect 50/50 shared custody arrangement, Louisiana law still requires the court to designate one parent as the domiciliary parent under R.S. 9:335(B). This parent has presumptive authority over major decisions — education, medical care, religious upbringing.

The non-domiciliary parent can challenge any decision, but they bear the burden of proving to a judge that the domiciliary parent's choice is detrimental to the child. In practice, the domiciliary designation is a tiebreaker: when parents disagree and can't resolve it through their plan's dispute resolution process, the domiciliary parent's decision stands unless a court intervenes.

Don't assume that 50/50 physical time means equal decision-making power. Negotiate the domiciliary designation carefully — it determines who has the default authority when you disagree.

Deviating from the 50/50 Default

The 2026 mandate creates a presumption, not an absolute rule. A judge can order an unequal schedule if the evidence supports it. Common reasons courts deviate:

• Geographic distance — parents living in different parishes or school districts makes midweek exchanges impractical
• Documented safety concerns — domestic violence history triggers the Post-Separation Family Violence Relief Act (PSFVRA), which creates a presumption against custody for the perpetrating parent
• Age of the child — some judges still favor primary placement with one parent for infants, though the statute doesn't create an age-based exception
• A parent's work schedule — shift work, frequent travel, or military deployment that conflicts with regular custody exchanges

The parent arguing against 50/50 bears the burden of proof. Vague objections ("I don't think it would work") won't overcome the statutory default — you need specific, documented reasons.

Preparing for a Shared Custody Arrangement

If you're heading into a custody negotiation or hearing, the Louisiana Child Custody & Parenting Plan Guide includes schedule comparison worksheets, a JCIP template that meets R.S. 9:335 requirements, and a child support alignment workbook that walks through both Worksheet A and Worksheet B calculations — so you understand the financial implications before you agree to a schedule.
