Louisiana’s New Equal Custody Law: What Every Parent Needs to Know Before August 1, 2026

If you are a parent in Lake Charles going through a divorce or custody dispute — or if you already have a custody order in place — a monumental shift in Louisiana family law is officially on the horizon. Starting August 1, 2026, new legislation (Act 605) will dramatically change how courts across the state, including the 14th Judicial District Court in Calcasieu Parish, handle child custody disputes. The change is not subtle: courts are now directed to start from equal sharing as the baseline, and a parent who wants a different arrangement will need to justify that departure. This post explains what Act 605 actually changes, what it does not change, and what it means for parents in Southwest Louisiana facing a custody proceeding after August 1.

The core of this legislative update is a shift toward a much stronger legal presumption of equal physical custody (50/50 time-sharing) between parents. If you are preparing for a divorce, heading into a custody battle, or wondering how this impacts your current arrangement, here is what you need to understand about the new legal framework.

What Did the Old Louisiana Custody Law Say?

Before Act 605, Louisiana’s approach to physical custody was framed as a preference, not a presumption. Louisiana courts operated under the standard that joint custody was presumed to be in the best interest of the child. However, the exact division of physical time was largely left to judicial discretion. Louisiana Revised Statute 9:335(A)(2)(b) provided that physical custody of children “should” be shared equally “to the extent it is feasible and in the best interest of the child.”

That language gave courts significant flexibility. “Should” is advisory. Judges had wide discretion to depart from equal physical custody without requiring either party to meet a demanding evidentiary standard. In practice, many custody arrangements fell well short of a true 50/50 physical split, particularly when one parent had traditionally been the primary caregiver. Many judges preferred a “home base” for children, where they were supposed to spend the majority of their time. This visitation schedule meant that the other parent could not have equal time by default.

Does Act 605 create an equal custody law?

Act 605 makes a targeted but important change to Louisiana’s joint custody implementation statute, R.S. 9:335(A)(2)(b). The new law changes the equal-physical-custody language from “should” to “shall,” making equal physical custody a much stronger statutory starting point when joint custody is ordered. Together the changes represent the most significant shift in Louisiana custody law in years.

R.S. 9:335(A)(2)(b): “Should” Becomes “Shall”

The existing statute at R.S. 9:335(A)(2)(b) is amended to change “should” to “shall.” The provision now reads that unless the court determines equal sharing is not feasible or in the best interest of the child, physical custody “shall” be shared equally.

In Louisiana statutory interpretation, “shall” is mandatory. “Should” is aspirational. This single word change converts what was a guiding preference into a legal mandate — the default outcome is equal physical custody, and departure from it requires a court finding, not just judicial discretion.

The new statute will read, “Unless the court determines it is not feasible or in the best interest of the child, physical custody of the child shall be shared equally.”

Before and After — A Direct Comparison

Old Law (Before Aug. 1, 2026)	New Law (Act 605, Effective Aug. 1, 2026)
Physical custody “should” be shared equally to the extent feasible	Physical custody “shall” be shared equally unless court finds it not feasible or not in best interest

What Act 605 Does NOT Change

Act 605 does not eliminate judicial discretion, and it does not mean every custody case in Louisiana will result in a 50/50 schedule. Several important things remain unchanged:

• The best-interest-of-the-child standard remains the overarching framework.
• Judges retain authority to order a different arrangement when the evidence supports it. The change raises the bar for departing from equal custody; it does not remove the door entirely.
• The statutory best-interest factors under Civil Code Article 134— emotional ties, each parent’s ability to provide care, the child’s history and stability, history of abuse or neglect — remain in place and still guide the court’s analysis.
• Act 605 does not override Louisiana’s domestic-abuse custody protections. If the court finds a history of family violence, domestic abuse, sexual abuse, or other serious safety concerns, La. R.S. 9:364 and La. R.S. 9:341 may still restrict custody or visitation even after the new equal-physical-custody language takes effect.
• Existing custody orders are not automatically modified by this law. Parents who want to seek a modification based on Act 605 will still need to satisfy the material change in circumstances standard — the new law does not, on its own, constitute a material change.

Does This Guarantee a 50/50 Custody Split?

While the new law heavily favors equal physical custody, it is not an absolute, ironclad guarantee in every single case. The primary standard in any family law matter remains the best interest of the child.

Judges in Lake Charles still retain the authority to deviate from a 50/50 schedule, but they now have the burden to prove why equal time shouldn’t happen. A court may grant unequal physical custody if:

• A parent has a history of family violence, domestic abuse, sexual abuse, substance abuse, or neglect. Louisiana’s domestic-abuse custody statutes, including La. R.S. 9:364 and La. R.S. 9:341, can still restrict custody or visitation regardless of Act 605.
• The logistical distance between the parents’ homes makes equal time detrimental to the child’s schooling or daily stability.
• A parent’s work schedule completely prevents them from maintaining a consistent 50/50 routine.

Importantly, if a judge creates a custody schedule that drifts from the presumed 50/50 split, then that ruling will face more scrutiny on appeal. Future appellate decisions will likely determine how strictly Louisiana courts must apply the new “shall be shared equally” language in contested custody cases.

What This Means for Parents in Lake Charles

If You Are Starting a New Custody Case After August 1

Equal physical custody is now the starting point. If you are filing for divorce or opening a custody proceeding after August 1, 2026, the court’s default position is that both parents share legal and physical custody equally. If you believe a different arrangement better serves your child, you should be prepared to present evidence showing why equal physical custody is not feasible or not in your child’s best interest.

If You Already Have a Custody Order

Act 605 does not automatically modify existing orders. If your current custody arrangement is working for your family, you are not required to change anything. However, if you already have a joint custody order that heavily favors one domiciliary parent, this new statutory framework may play a role if you decide to file for a modification of custody. Modifying an existing order still requires proving a material change in circumstances and showing that the proposed modification is in the child’s best interest, but the new presumption of equal time will heavily influence how these modification hearings are evaluated moving forward.

If You Are a Non-Domiciliary Parent with Less Than Equal Time

If you currently have less than equal parenting time under an existing order and want more, Act 605 changes the policy backdrop — but it does not change the modification standard. You still need a material change in circumstances to reopen a custody order. The existence of the new law alone is unlikely to satisfy that standard. What the new law does is signal the direction Louisiana courts are expected to move, which may affect how judges weigh modification requests going forward.
