Mississippi Joins 50-50 Custody Movement as Governor Signs HB 1662
Governor Tate Reeves signed House Bill 1662 into law in March 2026, making Mississippi the sixth state in the nation to establish a mandatory presumption of joint physical custody in divorce and custody proceedings. The law, which passed with unanimous support (118-0 in the House, 52-0 in the Senate), takes effect July 1, 2026, and requires Mississippi courts to begin all custody determinations with an assumption of equal parenting time.

Why This Law Fundamentally Changes Mississippi Custody Cases
HB 1662 shifts the burden of proof in Mississippi custody disputes from parents seeking equal time to parents seeking unequal arrangements. Under the previous framework established by Miss. Code Ann. § 93-5-24, Mississippi courts applied a best-interests-of-the-child standard without any presumptive starting point. Judges had broad discretion, and outcomes varied significantly across the state's 82 counties.
The new law requires courts to begin every custody determination with a presumption that equal physical custody serves the child's best interests. A parent seeking more than 50% of parenting time must now present evidence demonstrating why equal custody would harm the child. Courts must document their specific factual findings when ordering any arrangement other than 50-50.
This represents a dramatic departure from decades of Mississippi family law practice. Historical data from Mississippi courts shows that mothers received primary physical custody in approximately 68% of contested cases between 2015 and 2023. HB 1662 directly addresses this disparity by establishing equal time as the default starting point.
How Mississippi's New Law Compares to Other States
Mississippi joins five other states that have enacted similar presumptions since Kentucky became the first in 2018. The progression shows growing national momentum:
- Kentucky: 2018 (first state, immediate presumption)
- Arizona: 2018 (maximizing parenting time requirement)
- Arkansas: 2021 (equal physical custody presumption)
- West Virginia: 2022 (rebuttable presumption of joint custody)
- Florida: 2023 (equal time-sharing presumption)
- Mississippi: 2026 (mandatory joint physical custody presumption)
Kentucky's experience provides useful data. According to research published in the Journal of Divorce & Remarriage in 2023, contested custody litigation in Kentucky decreased by approximately 35% in the three years following implementation. The presumption appears to encourage settlement by establishing clear expectations for both parties.
Mississippi's version includes several notable provisions. First, the presumption applies only to physical custody, not legal custody (decision-making authority). Second, courts retain full authority to deviate when evidence demonstrates that equal time would endanger the child's physical, mental, or emotional health. Third, the law explicitly requires judges to create written findings explaining any deviation from the presumption.
What This Means for Mississippi Parents Filing After July 1, 2026
The effective date creates a clear dividing line in Mississippi family law. Parents filing custody petitions on or after July 1, 2026, will proceed under the new presumption. Those with existing custody orders are not automatically affected.
Miss. Code Ann. § 93-5-24 will continue to govern the best-interests analysis, but courts must now apply that analysis within the framework of the 50-50 presumption. The Albright factors, established by the Mississippi Supreme Court in Albright v. Albright (1983), remain relevant but function differently under the new law. Rather than using these factors to determine an initial custody arrangement, courts will use them to evaluate whether deviation from equal time is warranted.
Practically, this means parents in contested custody cases should expect to present evidence specifically addressing why equal time either does or does not serve their child's interests. Vague assertions about one parent being "better" will carry less weight. Courts will focus on concrete factors: work schedules, geographic proximity, each parent's historical involvement in daily care, and any documented concerns about safety or wellbeing.
Practical Takeaways for Mississippi Parents
-
Check your filing date: The presumption applies only to new custody petitions filed on or after July 1, 2026. If you have an existing custody order, HB 1662 does not automatically modify your arrangement.
-
Prepare for equal time as the baseline: If you want more than 50% of parenting time, you must be prepared to present specific evidence explaining why equal custody would not serve your child's best interests. General preferences or historical arrangements are no longer sufficient.
-
Document your parenting involvement now: Courts will examine each parent's actual involvement in the child's daily life. Keep records of school attendance, medical appointments, extracurricular activities, and daily care responsibilities.
-
Consider geographic implications: Equal custody requires practical logistics. Parents living 100 miles apart face different challenges than those in the same school district. Courts may consider distance when evaluating whether 50-50 time is feasible.
-
Understand the modification standard: Parents with existing orders who want to invoke the new presumption must still demonstrate a material change in circumstances under Miss. Code Ann. § 93-5-24. The new law alone does not constitute such a change.
Frequently Asked Questions
Does HB 1662 automatically change my existing custody order?
No, HB 1662 does not automatically modify existing custody orders in Mississippi. The law applies only to new custody petitions filed on or after July 1, 2026. Parents with current orders must file a modification petition and demonstrate a material change in circumstances under Miss. Code Ann. § 93-5-24 to seek a new arrangement.
Can a Mississippi court still award primary custody to one parent under the new law?
Yes, Mississippi courts retain full authority to award unequal custody when evidence supports deviation from the 50-50 presumption. The law requires judges to document specific findings explaining why equal time would not serve the child's best interests. Factors including domestic violence, substance abuse, geographic distance, or a child's special needs may justify deviation.
How does the 50-50 presumption affect child support calculations in Mississippi?
Mississippi child support guidelines under Miss. Code Ann. § 43-19-101 consider parenting time in calculating support obligations. When parents share equal physical custody, courts typically apply an income-shares model that accounts for each parent's time with the child. Equal custody often reduces but does not eliminate child support obligations for the higher-earning parent.
What evidence can overcome the joint custody presumption in Mississippi?
Mississippi courts may deviate from the 50-50 presumption based on documented evidence of domestic violence, child abuse or neglect, substance abuse affecting parenting ability, significant geographic distance between homes, a child's special medical or educational needs, or a parent's work schedule that prevents meaningful daytime involvement. The burden falls on the parent seeking unequal time.
When exactly does HB 1662 take effect in Mississippi?
HB 1662 takes effect on July 1, 2026. The presumption applies to custody petitions filed on or after that date. Cases filed before July 1, 2026, will proceed under the prior legal framework, even if the final hearing occurs after the effective date. Parents planning to file should note this deadline.
