Louisiana's Act 605 takes effect August 1, 2026, amending La. R.S. § 9:335 so physical custody "shall be shared equally" between parents in every case unless a court finds equal sharing infeasible or contrary to the child's best interest. The law passed unanimously and became effective without the governor's signature, but judges keep discretion and existing orders are not automatically changed.

According to reporting from the American Press, the measure cleared the Louisiana Legislature unanimously and became law without Gov. Jeff Landry's signature. The single-word change — from "should" to "shall" — carries real legal weight in how Louisiana courts approach the division of parenting time.
Why This Matters Legally
The word "shall" transforms a suggestion into a directive. Under the prior version of La. R.S. § 9:335, physical custody in a joint-custody arrangement "should" be shared equally to the extent feasible — language courts frequently treated as aspirational rather than binding. Act 605 replaces "should" with "shall," instructing courts to start from a position of equal (50/50) physical custody in every joint-custody case.
This is a meaningful shift in the burden of the conversation. Previously, a parent seeking equal time often had to build the case for why 50/50 served the child. Now the statutory default points toward equal sharing, and the parent opposing it must demonstrate that equal custody is either not feasible or not in the child's best interest. The legal presumption has moved, even though the ultimate authority still rests with the judge.
Importantly, Act 605 does not eliminate judicial discretion. The statute expressly allows courts to depart from equal sharing when it is impractical — for example, when parents live far apart, work incompatible schedules, or when equal time would disrupt a child's stability. The best-interest-of-the-child standard remains the polestar of every custody decision in Louisiana. What changed is the starting point, not the destination.
How Louisiana Law Handles This
Louisiana custody law operates within the civil-law framework and centers on the child's best interest under La. C.C. art. 134, which lists the factors courts weigh — including the love and affection between child and each parent, the stability of each home, and each parent's capacity to provide care. Act 605 does not repeal these factors; it layers an equal-time presumption on top of them within joint-custody determinations governed by La. R.S. § 9:335.
Under Louisiana's system, joint custody typically involves the designation of a domiciliary parent — the parent with whom the child primarily resides for practical matters — while both parents share decision-making authority. Act 605's equal-sharing language addresses the physical-custody (parenting time) component, pushing courts toward a genuine 50/50 split of days rather than a primary-parent arrangement with visitation for the other.

Existing custody orders are not automatically rewritten by Act 605. Louisiana requires a party seeking to change a considered custody decree to show a material change in circumstances and that modification serves the child's best interest — the Bergeron standard for stipulated versus considered judgments still applies. A new statute alone is generally not treated as an automatic material change, so parents with current orders should consult counsel before assuming the law reopens their case.
Practical Takeaways
-
Note the effective date. Act 605 applies to custody determinations on or after August 1, 2026. Cases filed or decided before that date fall under the prior "should" standard unless properly modified.
-
If you have an existing order, do not assume it changes automatically. The law does not reopen settled custody judgments. Modifying a considered decree still requires proving a material change in circumstances plus best interest.
-
Document your parenting involvement now. Because equal sharing is the new starting point, contemporaneous records of caregiving, school involvement, and a workable schedule strengthen your position — whether you seek equal time or argue it is not feasible.
-
Address feasibility head-on. Distance between homes, work schedules, and school logistics are the exact factors a court will weigh when deciding whether to depart from 50/50. Build a concrete, child-centered schedule proposal.
-
Consider structured alternatives. Mediation and collaborative divorce let parents design a custom parenting plan that honors the equal-sharing default while accommodating real-life constraints, often faster and less expensively than litigation.
-
Get jurisdiction-specific guidance. Custody outcomes turn on facts. A brief consultation with a Louisiana family law attorney can clarify how Act 605 interacts with your particular circumstances.
