Louisiana Act 605: Custody 'Shall Be Shared Equally' Aug. 1, 2026

Louisiana's Act 605 changes one word in the state's custody statute — from "should" to "shall" — and that single word shifts the starting point for physical custody. Effective August 1, 2026, La. R.S. 9:335(A)(2)(b) will direct courts that physical custody "shall be shared equally" between parents, though judges keep discretion to depart when equal sharing is not feasible or not in the child's best interest.

Key Facts

Why this ruling matters legally

Act 605 elevates equal shared physical custody from a preference to a statutory directive in Louisiana. The prior version of La. R.S. 9:335 told courts that physical custody "should" be shared equally to the extent feasible — aspirational language a judge could weigh against other factors. Replacing "should" with "shall" makes equal sharing the express starting point that a court applies unless the record justifies departing from it.

This matters because word choice in statutes carries real legal weight. According to The Center Square, sponsor Rep. Kyle Green Jr. authored HB 1239, which passed the Legislature unanimously in the 2026 session and became law without Gov. Jeff Landry's signature. Unanimous passage signals broad legislative agreement that Louisiana children generally benefit from meaningful time with both parents after a separation.

Importantly, the change is not a mandate that every case ends in a 50/50 split. Judges retain discretion to order a different arrangement when equal custody is not feasible — because of distance, work schedules, or a parent's circumstances — or when it would not serve the child's best interest. The best-interest standard, long the touchstone of Louisiana custody law, remains fully intact. Act 605 changes the default, not the ultimate authority of the court.

How Louisiana law handles shared custody

Louisiana already favored joint custody before Act 605. Under La. R.S. 9:335, when a court awards joint custody, it must fix a plan allocating the time each parent spends with the child so that the child is assured of frequent and continuing contact with both parents. The statute's existing feasibility and best-interest guardrails are precisely why Act 605 preserves judicial discretion: the Legislature strengthened the default without stripping courts of the ability to tailor orders to real families.

Custody decisions in Louisiana still run through the best-interest factors codified at La. Civ. Code art. 134, which direct courts to weigh the child's needs, each parent's capacity to provide care, the stability of the home, and the child's relationship with each parent, among other considerations. Act 605 does not repeal or override Article 134. Instead, equal physical custody becomes the presumptive allocation that a court then tests against these established factors.

The timing rule is critical for families already under a custody order. Act 605 does not automatically modify existing judgments. A parent who wants to move an older order toward the new equal-sharing default must still file for modification and, in Louisiana, meet the applicable change-in-circumstances standard — which is heightened when the prior custody arrangement was set by a considered decree. The statute changes the road ahead, not the orders already entered.

Legislators are also watching a related measure. A separate 2026 bill, HB 473, would go further than Act 605 by creating an explicit rebuttable presumption of equal shared custody — one that could be overcome only by clear and convincing evidence. Clear and convincing is a demanding evidentiary standard, higher than the ordinary preponderance-of-the-evidence used in most civil matters. If HB 473 becomes law, a parent opposing equal custody would carry a substantially heavier burden than Act 605 alone imposes. As of now, HB 473 is a proposal, not law.

Practical takeaways

1. Know the effective date. Act 605 applies to custody determinations made on or after August 1, 2026. Cases resolved before that date fall under the prior "should" language unless a party later seeks modification.

2. Existing orders stay in place until changed. If you already have a custody judgment, it does not automatically convert to 50/50. You must file a motion to modify and satisfy Louisiana's modification standard. Review your order with an attorney before assuming anything changes.

3. Build your parenting plan around feasibility. Because judges can still depart from equal sharing when it is not workable, document commute distances, school schedules, and work hours. A concrete, child-focused parenting plan strengthens your position whether you seek or oppose equal custody.

4. Estimate the time split before you negotiate. Use our parenting time calculator to model how an equal or near-equal schedule would actually work across a calendar year, including holidays and school breaks.

5. Understand the downstream effect on support. Physical custody allocation influences child support in Louisiana's shared-custody calculations. If your time split changes, your support obligation may change too. Run the numbers with our child support calculator.

6. Consider lower-conflict paths. Equal custody works best when parents cooperate. Exploring mediation or collaborative divorce can help you reach a durable schedule without a contested trial.
