Louisiana courts must now start from a presumption of equal physical custody once Act 605 takes effect August 1, 2026. The law changes one word in La. R.S. § 9:335 — physical custody 'shall' be shared equally rather than 'should' — strengthening the equal-parenting-time default while preserving judicial discretion in abuse and unfitness cases.

Act 605 originated as House Bill 1239, sponsored by Rep. Kyle Green Jr., and passed the Louisiana Legislature unanimously before becoming law without Gov. Jeff Landry's signature, according to The Center Square. The single-word amendment carries outsized legal weight because 'shall' is mandatory language, while 'should' is aspirational.
Why this matters legally
The word 'shall' converts equal custody from a preference into a directive. Under the prior version of La. R.S. § 9:335, courts were told custody 'should' be shared equally to the extent feasible — a standard judges could readily set aside. Act 605 replaces that soft guidance with mandatory framing, meaning Louisiana courts must now treat 50/50 physical custody as the starting baseline and articulate specific reasons before deviating from it.
This is a meaningful shift in the burden of persuasion. Before, a parent seeking equal time often had to affirmatively justify it. After August 1, 2026, the parent seeking to reduce the other parent's time will more often carry the burden of showing why unequal custody serves the child's best interest. The change aligns Louisiana with a national trend toward shared-parenting presumptions that has gained ground in Kentucky, Arizona, and West Virginia over the past decade.
The reform is not absolute. Act 605 preserves judicial discretion in cases involving domestic abuse or parental unfitness, and it explicitly does not apply retroactively. Existing custody orders entered before August 1, 2026 remain valid unless a parent files for modification and demonstrates a material change in circumstances under existing Louisiana law.

How Louisiana law handles this
Louisiana determines custody under the best-interest-of-the-child standard codified in La. C.C. art. 134, which lists factors such as each parent's capacity to provide love and guidance, the child's existing stability, and the moral fitness of each parent. Act 605 does not repeal these factors — it recalibrates how La. R.S. § 9:335 instructs courts to apply them when structuring the physical-custody schedule.
Under the amended statute, when a court awards joint custody, the physical-custody implementation order 'shall' provide that the child spend substantially equal time with each parent to the extent feasible and in the child's best interest. The 'to the extent feasible' and 'best interest' qualifiers remain, so a judge can still order an unequal schedule where distance between homes, work schedules, or the child's needs make a true 50/50 split impractical.
The domestic-abuse carve-out is critical. Louisiana's Post-Separation Family Violence Relief Act, La. R.S. § 9:364, already restricts custody and visitation for a parent with a history of family violence. Act 605 does not override those protections. A documented history of abuse can defeat the equal-custody baseline entirely, and courts retain authority to order supervised or restricted visitation. Understanding parenting plans and how they translate a custody award into a day-to-day schedule is the practical next step for most families.

Practical takeaways
-
If your custody case is unresolved, note the August 1, 2026 effective date. Filings and hearings that occur after that date will apply the mandatory 'shall' standard, so timing may affect your strategy.
-
Existing orders are not automatically changed. Act 605 is not retroactive. To benefit from the new baseline on an old order, you must file for modification and show a material change in circumstances under existing Louisiana law.
-
Document your parenting involvement. Because the new standard favors equal time, contemporaneous records of your caregiving — school pickups, medical appointments, overnights — strengthen a request for a 50/50 schedule.
-
Abuse and unfitness still matter. If safety is a concern, the Post-Separation Family Violence Relief Act and the best-interest factors in La. C.C. art. 134 continue to protect children regardless of the new baseline.
-
Build a workable plan, not just a number. Equal time only works if the logistics do. Map out a concrete schedule and consider using our parenting-time calculator before you propose a plan to the court.
