Louisiana's Act 605 (HB 1239) takes effect August 1, 2026, amending La. R.S. § 9:335 to change one word with major consequences: physical custody now "shall be shared equally" between parents rather than "should" be shared. The law applies only to new custody proceedings and does not automatically modify existing orders.
That single-word shift — from "should" to "shall" — moves Louisiana from a suggestion toward a directive. Courts must now aim for a 50/50 split of physical custody unless a judge finds equal sharing unfeasible or contrary to the child's best interest. For any Louisiana parent filing after August 1, this reframes the starting point of every custody negotiation.

Why This Matters Legally
Act 605 changes the legal presumption Louisiana courts apply when dividing parenting time. Before this amendment, La. R.S. § 9:335 instructed courts that physical custody "should" be shared equally to the extent feasible — aspirational language that judges could weigh against a broad set of factors. The word "shall" converts that aspiration into a command, meaning equal physical custody is now the presumptive outcome that a party must overcome with specific evidence.
This matters because the burden effectively shifts. Under the old "should" language, a parent seeking equal time had to persuade the court that a 50/50 arrangement served the child. Under the new "shall" language, the equal split is the baseline, and the parent opposing it must demonstrate that equal sharing is either unfeasible or contrary to the child's best interest. That reordering of the burden can change the trajectory of contested cases.
The legislation passed unanimously and became law without Governor Jeff Landry's signature, reflecting rare bipartisan agreement that both parents should presumptively share meaningful time. The reform tracks a national movement — states including Kentucky and Arkansas have adopted similar rebuttable presumptions of equal or joint physical custody in recent years. Understanding how child custody arrangements work is now essential for any Louisiana parent entering a divorce.
One critical caveat: Act 605 is prospective only. It governs custody proceedings initiated on or after August 1, 2026, and does not automatically reopen or modify existing custody orders. A parent with a current order who wants to invoke the new standard would still need to file a modification and satisfy Louisiana's material-change-in-circumstances requirement.
How Louisiana Law Handles This
Louisiana custody law starts from a preference for joint custody. Under La. R.S. § 9:335, when a court awards joint custody, it designates a domiciliary parent and allocates physical custody so that each parent has "frequent and continuing contact" with the child. Act 605 sharpens subsection (A)(2)(b), which addresses how physical custody is allocated within a joint-custody award.
Equal physical custody under the amended statute does not mean a rigid, robotic split down to the hour. The statute preserves judicial discretion through its two escape valves: a court may deviate from 50/50 when equal sharing is "unfeasible" — for example, when parents live far apart or work incompatible schedules — or when it would be "contrary to the best interest of the child." That best-interest analysis still flows through the twelve factors listed in La. C.C. art. 134, which include each parent's capacity to provide care, the child's ties to home and community, and the moral fitness of each party.
Because the practical result turns on a workable schedule, Louisiana parents should think concretely about logistics. Distance between homes, school zones, and each parent's availability all bear on whether a court finds an equal split "feasible." A well-drafted parenting plan that demonstrates how 50/50 will actually function — pickups, holidays, exchanges — carries real weight under the new standard. You can model different arrangements with our parenting time calculator for Louisiana to see how various splits translate into overnights and holidays.
Equal custody also intersects with support. Louisiana calculates child support under a shared-custody worksheet when each parent has the child for a substantial number of days, so a move toward 50/50 can materially change the support number. Parents can estimate the effect using our Louisiana child support calculator.
Practical Takeaways
-
Confirm your timeline. Act 605 applies to custody proceedings filed on or after August 1, 2026. If your case is already pending or your order is already final, the equal-custody default does not automatically apply — you would need to file a modification and prove a material change in circumstances.
-
Build a feasibility case now. Because the statute lets courts deviate when equal sharing is "unfeasible," document the logistics early: home locations, school district lines, commute times, and work schedules. Whether you support or oppose a 50/50 split, feasibility evidence will drive the outcome.
-
Draft a concrete parenting plan. A vague request for "equal time" is weaker than a detailed parenting plan showing exact overnights, exchange points, and holiday rotation. Courts respond to workable plans, not aspirations.
-
Reassess child support expectations. A shift toward equal physical custody can change which support worksheet applies. Run the numbers before you negotiate so no one is surprised at the table.
