Mississippi lawmakers passed House Bill 1662 on April 1, 2026, establishing a rebuttable presumption that joint custody with equally shared parenting time serves children's best interests. Governor Tate Reeves received the bill April 7th and has until April 13, 2026 to sign, veto, or allow it to become law without signature. If enacted, Mississippi becomes the sixth US state requiring courts to start with equal custody unless proven otherwise, with the new standard taking effect July 1, 2026.

Why This Matters Legally
HB 1662 fundamentally reverses Mississippi's current custody framework by requiring judges to begin every case with the assumption that equal time benefits children. Under existing Miss. Code § 93-5-24, Mississippi courts apply the "Albright factors"—a list of custody considerations established by the state Supreme Court in Albright v. Albright, 437 So. 2d 1003 (Miss. 1983). Those factors give judges broad discretion to craft custody arrangements based on each child's circumstances, with no mathematical starting point.
The new law creates a rebuttable presumption, meaning courts must order joint legal custody and approximately equal physical custody unless one parent proves by clear and convincing evidence that equal time would harm the child. This 50/50 default applies to all initial custody determinations and modifications filed on or after July 1, 2026. Parents seeking unequal arrangements must now overcome a statutory hurdle that didn't exist under the Albright framework.
Mississippi joins Arizona, Arkansas, Kentucky, Missouri, and West Virginia as states with mandatory equal custody presumptions. The timing matters: five other states considered similar legislation in 2025-2026, signaling a national shift toward equal parenting laws. Courts in states with these presumptions report 60-70% of custody orders include approximately equal time, compared to 20-30% in discretionary jurisdictions.
How Mississippi Currently Handles Custody
Mississippi family courts currently decide custody using the best-interest standard codified in Miss. Code § 93-5-24, which lists factors including parental fitness, child's age and health, continuity of care, emotional ties, moral fitness, home stability, and each parent's employment. The Mississippi Supreme Court clarified in Albright that no single factor controls, and judges may weigh factors differently case by case.
Under existing law, joint legal custody (shared decision-making authority) requires parental cooperation and communication ability per Miss. Code § 93-5-23. Physical custody arrangements vary widely: one parent may have primary physical custody with the other receiving visitation, or parents may share physical custody on schedules ranging from 60/40 splits to alternating weeks. Mississippi courts have no obligation to consider equal time arrangements first.
Current modification standards under Miss. Code § 93-5-24(9) require showing a material change in circumstances adversely affecting the child before courts reconsider custody. HB 1662 will apply the equal-time presumption to modifications filed after July 1, 2026, potentially making it easier for non-custodial parents to seek increased time by invoking the new statutory preference.
Mississippi also recognizes grandparent visitation rights under Miss. Code § 93-16-3 when parents are divorced, separated, or deceased. HB 1662 does not modify grandparent rights, but courts may consider how equal parenting schedules affect extended family time when evaluating best interests.
Practical Takeaways for Mississippi Parents
-
Pending Cases Get Grandfathered: The July 1, 2026 effective date means custody cases filed before that date proceed under current Albright discretion. Parents in active litigation should clarify with their attorney whether the new presumption applies to their case.
-
Rebutting the Presumption Requires Evidence: Parents opposing equal time must present clear and convincing proof that 50/50 custody would harm the child. Acceptable evidence typically includes domestic violence documentation, substance abuse records, mental health evaluations showing parental incapacity, or geographic distance making equal time logistically impossible. Personal preference or work schedule inconvenience won't overcome the presumption.
-
Joint Legal Custody Remains Separate: HB 1662's physical custody presumption operates independently from legal custody (decision-making authority). Courts may still award one parent final say on education, medical care, or religious upbringing even when physical time splits equally, particularly when parents demonstrate poor communication.
-
Modifications Get Easier for Non-Custodial Parents: Parents currently receiving every-other-weekend visitation can petition for modification after July 1, 2026 invoking the new presumption. They must still prove material change in circumstances, but the statutory preference for equal time strengthens their position.
-
Logistics Matter More Than Ever: Equal custody works best when parents live within reasonable proximity (typically same school district), maintain similar household routines, and can coordinate schedules. Parents should address transportation, school enrollment, medical care coordination, and holiday scheduling in detailed parenting plans to make 50/50 arrangements functional.
When Equal Custody May Not Apply
Courts can deviate from the 50/50 presumption when evidence proves unequal time better serves the child. Domestic violence documented through police reports, protective orders, or criminal convictions typically rebuts the presumption, as do verified substance abuse issues requiring treatment. Parents with severe mental illness that impairs caregiving, those incarcerated or frequently absent due to military deployment, and parents living in different states often cannot exercise equal physical custody.
Very young children (infants under 12 months) present special considerations: some family law experts argue frequent overnight transitions harm attachment development, though research on this question remains mixed. Mississippi courts will likely consider children's developmental needs when evaluating whether equal time serves best interests for different age groups.
Geographic distance creates practical barriers—if one parent lives two hours away, alternating weeks becomes feasible but daily school-night exchanges do not. Courts may approve unequal summer vacation schedules combined with weekend-only visits during the school year when distance prevents true 50/50 splits.
FAQ: Mississippi's New Joint Custody Law
Does HB 1662 guarantee I'll get equal time with my child?
HB 1662 creates a starting presumption, not an absolute guarantee. Courts must begin with the assumption that 50/50 custody serves your child's best interests, but your ex-spouse can present clear and convincing evidence that equal time would cause harm. If they prove domestic violence, substance abuse, or other legitimate concerns, judges may order unequal arrangements. Approximately 60-70% of cases in presumption states result in equal or near-equal time.
When does the new law take effect and does it apply to my existing custody order?
The law takes effect July 1, 2026, and applies only to new custody cases and modification petitions filed on or after that date. Existing custody orders remain in force under current law. If you want to modify your current order, you must still prove material change in circumstances under Miss. Code § 93-5-24(9), but after July 1st you can invoke the equal-time presumption to strengthen your modification request.
What evidence do I need to overcome the 50/50 presumption?
You must present clear and convincing evidence—a higher standard than typical family court proceedings—that equal custody would harm your child. Acceptable evidence includes documented domestic violence (police reports, protective orders, criminal convictions), verified substance abuse requiring treatment (failed drug tests, DUI convictions, treatment records), mental health evaluations showing parental incapacity, or geographic distance exceeding 100 miles making equal exchanges impossible. Work schedule conflicts or personal preferences typically don't meet this standard.
How does this affect child support calculations?
Mississippi calculates child support using income shares guidelines under Miss. Code § 43-19-101. When parents share physical custody approximately equally (each parent has child at least 40% of overnights annually), courts may adjust support obligations to account for duplicated expenses. However, equal time doesn't automatically mean zero support—the higher-earning parent typically still pays some amount to equalize household resources for the child's benefit.
Can grandparents still get visitation under the new law?
Yes. HB 1662 doesn't modify Mississippi's grandparent visitation statute at Miss. Code § 93-16-3, which allows grandparents to petition for visitation when parents are divorced, separated, or deceased. Courts may consider how equal parenting schedules affect grandparent time when evaluating visitation requests, but grandparents retain independent rights to seek court-ordered visitation regardless of how parents split custody.
What Happens Next
Governor Reeves has three options before the April 13th deadline: sign HB 1662 into law, veto it (requiring legislative override), or allow it to become law without signature after the 5-day review period expires. If signed or enacted through inaction, the Mississippi Administrative Office of Courts will likely issue guidance to family court judges on applying the new presumption, and the Mississippi Bar's Family Law Section may publish practice advisories for attorneys handling custody cases.
Parents currently in custody litigation should consult Mississippi family law attorneys about strategic implications—cases nearing trial before July 1st proceed under current discretion, while cases likely to extend past that date may warrant holding final hearings until the presumption takes effect. Parents contemplating modification petitions may benefit from waiting until after July 1st to invoke the statutory preference for equal time.
