Louisiana's Act 605 changes one word in the state's custody statute — from custody that "should" be shared equally to custody that "shall" be shared equally — and that single edit strengthens the presumption of 50-50 parenting time for divorcing parents. Signed into law without Gov. Jeff Landry's signature, Act 605 takes effect August 1, 2026, amending La. R.S. 9:335.

Why this ruling changes Louisiana custody law
Act 605 raises the legal default for parenting time in Louisiana from a suggestion to a directive. Authored by Rep. Kyle Green Jr. and passed unanimously, House Bill 1239 became law without Gov. Jeff Landry's signature and takes effect August 1, 2026. The change from "should" to "shall" in La. R.S. 9:335 matters because in legal drafting, "should" is aspirational while "shall" is mandatory. Courts now start from a stronger presumption that each parent receives roughly equal time with the child under a joint custody plan.
The practical effect is a shift in the burden of proof. Before Act 605, a parent arguing for unequal time worked against a soft preference. Beginning August 1, 2026, a parent who wants to deviate from a 50-50 split must present affirmative evidence that equal sharing is impractical or contrary to the child's best interest. This is a rebuttable presumption, not an absolute rule — the best interest of the child standard under La. R.S. 9:335 still governs, and judges keep discretion to order a different arrangement when the facts warrant it.
Louisiana is not acting in isolation. As reported by Yahoo News, the state joins Mississippi and a broader 2026 wave of states strengthening equal-parenting presumptions. This reflects a national policy trend toward shared-custody defaults, driven by research on the benefits of both parents remaining actively involved after divorce.
How Louisiana law handles shared custody
Louisiana law presumes that joint custody serves the child's best interest, and Act 605 sharpens the time-sharing component of that framework. Under La. R.S. 9:335, when a court awards joint custody, it must designate a domiciliary parent and set an implementation plan allocating physical custody. The amended subsection (A)(2)(b) now directs that physical custody "shall be shared equally" to the extent feasible and in the child's best interest.
The domiciliary parent designation remains important and is unaffected by the word change. Under La. R.S. 9:335, the domiciliary parent is the parent with whom the child primarily resides for administrative purposes and who holds decision-making authority subject to the other parent's rights. Even with a 50-50 time split, Louisiana courts typically still name a domiciliary parent, so equal time does not automatically eliminate that role.
Judicial discretion survives Act 605 in specific circumstances. A court may order unequal parenting time when equal sharing is impractical — for example, when parents live far apart, when work schedules conflict with a child's routine, or when a history of family violence or substance abuse makes shared time unsafe. Louisiana's child custody framework continues to prioritize stability and safety, and Act 605 does not override the best-interest analysis; it changes only the starting presumption. Parents mapping out a schedule can use a parenting time calculator to model how an equal split translates into actual days.
Practical takeaways for Louisiana parents
Act 605 affects anyone negotiating or litigating custody in Louisiana after August 1, 2026. Here is what to do with this information:
-
Understand the new default. If you are seeking equal parenting time, the amended La. R.S. 9:335 now works in your favor as a stronger presumption. Frame proposed schedules around a 50-50 split as the baseline.
-
Prepare evidence if you seek a deviation. A parent who wants more or less than equal time must document why equal sharing is impractical or not in the child's best interest — distance, safety concerns, a child's special needs, or scheduling realities.
-
Draft a detailed parenting plan. Equal time still requires a workable parenting plan covering holidays, transportation, and decision-making. A well-drafted plan reduces future conflict regardless of the time split.
-
Consider mediation. Because Act 605 sets equal time as the starting point, many parents can reach agreement faster through mediation rather than contested litigation, saving time and legal fees.
-
Know the timeline. The law applies to matters on and after August 1, 2026. If your case is pending near that date, ask your attorney how the change affects your strategy. Our divorce timeline calculator can help you understand where your case sits.

Get individualized guidance. Custody outcomes turn on specific facts. Build a personalized divorce roadmap and, when you need representation, find a divorce attorney who practices family law in your parish.
If you are facing a custody question in Louisiana, understanding how Act 605 reshapes the parenting-time presumption is a smart first step, but it is not a substitute for advice tailored to your family. A Louisiana family law attorney can evaluate how the amended statute applies to your circumstances and help you build a plan that holds up in court.
