Louisiana's Act 605 takes effect August 1, 2026, directing courts to start from equal 50-50 physical custody as the baseline by changing the statutory word "should" to "shall." Any parent seeking a different arrangement must now justify the departure, though judges retain discretion when equal custody is not feasible or not in a child's best interest, according to the Colonna Law Firm.

Act 605 is the second Deep South equal-custody measure to arrive in the summer of 2026, following Mississippi's HB 1662. The linguistic shift from "should" to "shall" is not cosmetic. In statutory drafting, "shall" signals a mandatory directive, while "should" reads as advisory. That single-word change is what elevates equal custody from an encouraged option to the presumptive floor a court works from before hearing evidence.
Why this matters legally
Act 605 reallocates the practical burden in Louisiana custody cases. Before the amendment, a parent arguing for equal timesharing had to affirmatively persuade the court that 50-50 served the child. Under the new "shall" framing, equal physical custody becomes the presumed baseline, so the parent seeking a lopsided schedule now carries the practical burden of justifying the deviation with specific evidence.
This matters because the starting point in a custody analysis heavily influences the outcome. Judges anchor to the baseline the statute gives them, then adjust for the facts. When the baseline is 50-50 rather than a blank slate, borderline cases that once tilted toward one primary parent will more often resolve near equal time. The child custody analysis still runs through Louisiana's best-interest factors, but the default has moved.
Critically, Act 605 does not create an absolute right to equal custody. Louisiana courts retain discretion to order a different arrangement when 50-50 is not feasible — for example, when parents live far apart, work incompatible schedules, or when evidence shows equal time would harm the child. Domestic violence, substance abuse, and a child's established routine remain powerful reasons a court can and will depart from the baseline.
How Louisiana law handles this
Louisiana custody decisions are governed by the best interest of the child standard, and Act 605 layers the equal-custody baseline on top of that existing framework rather than replacing it. The controlling factors live in La. C.C. art. 134, which lists considerations such as the love and affection between each parent and child, each parent's capacity to provide for the child's needs, the stability of each home, and the moral fitness of each parent.
Implementation of custody orders continues under La. R.S. 9:335, the joint custody implementation statute Act 605 amends. That provision governs how courts allocate physical custody and designate a domiciliary parent. By inserting "shall" language pointing courts toward equal timesharing, the Legislature has instructed judges to build the implementation plan around a 50-50 division unless the record justifies otherwise.
Louisiana already favored joint custody as the default legal arrangement under La. C.C. art. 132. The distinction Act 605 sharpens is between joint legal custody, which concerns decision-making authority, and physical custody, which concerns where the child actually spends time. Louisiana parents have long shared joint legal custody in most cases; Act 605 pushes physical timesharing toward equality as well. Parents building a schedule should understand how parenting plans translate a 50-50 baseline into a workable week-to-week calendar, and can model different splits with our parenting time calculator.
Practical takeaways
Act 605 changes how Louisiana parents should prepare for a custody dispute filed on or after August 1, 2026. The following steps reflect the new baseline.
-
Assume 50-50 is the starting point. If you want equal time, you are now aligned with the statutory default and should focus on demonstrating you can execute an equal schedule reliably.
-
Build the case for deviation early if you seek unequal time. Because you carry the practical burden, document concrete reasons — distance between homes, work schedules, safety concerns, or a child's special needs — with dates, records, and specifics rather than general assertions.
-
Draft a detailed parenting plan. Courts implementing a 50-50 baseline need a functional plan covering exchanges, holidays, school-year versus summer schedules, and decision-making. A vague plan invites the court to impose its own.
-
Preserve evidence of your involvement. School pickups, medical appointments, extracurricular attendance, and daily caregiving records show you can sustain equal time — the exact showing the new baseline rewards.
-
Consider mediation. A negotiated agreement lets both parents shape the schedule around their actual lives rather than a courtroom presumption. Mediation and collaborative divorce often produce more durable custody arrangements than litigation.
-
Understand this applies going forward. Act 605 governs cases filed on or after the effective date. Existing orders remain in place unless a parent files for modification and meets Louisiana's material-change-in-circumstances standard.
Louisiana's move mirrors a broader regional trend, with Mississippi's HB 1662 landing the same summer, suggesting Deep South legislatures are converging on equal-custody presumptions as the policy default. Whether the on-the-ground results match the statutory language will depend on how individual judges weigh feasibility and best-interest evidence against the new baseline.
