What Happened: Mississippi Sends Mandatory 50-50 Custody Bill to Governor
On April 1, 2026, Mississippi lawmakers delivered House Bill 1662 to Governor Tate Reeves, establishing a rebuttable presumption that equal (50-50) parenting time serves children's best interests in divorce and custody cases. The governor has until April 13, 2026 to sign, veto, or allow the bill to become law without his signature. If enacted, Mississippi becomes the sixth US state with mandatory joint custody presumption, joining Kentucky, Arkansas, Missouri, West Virginia, and Florida, with an effective date of July 1, 2026.

Why This Bill Fundamentally Changes Mississippi Custody Law
Mississippi currently operates under Mississippi Code § 93-5-24, which requires judges to determine custody based on what serves the child's best interest without any presumption favoring equal time. Judges consider 12 statutory factors including each parent's willingness to facilitate the other's relationship with the child, the child's adjustment to home and school, and each parent's mental and physical health. Under existing law, courts can award any custody arrangement from primary physical custody to one parent (with the other receiving visitation) to various shared arrangements.
HB 1662 flips this framework by creating a starting presumption: unless evidence shows otherwise, Mississippi courts must begin with the assumption that 50-50 physical custody (equal parenting time) serves the child's best interest. This is a "rebuttable presumption," meaning either parent can present evidence that equal time would harm the child, but the burden shifts. Instead of a parent arguing FOR equal time, they now must argue AGAINST it if they want a different arrangement.
This represents the most significant shift in Mississippi family law since the state eliminated permanent alimony considerations in 2014. According to Mississippi Today's reporting, supporters argue equal parenting time benefits children by maintaining strong relationships with both parents post-divorce, while opponents worry the presumption may not account for cases involving domestic violence, geographic distance, or parents with vastly different work schedules.
How the New Law Would Work in Mississippi Courts
Under HB 1662, Mississippi judges handling divorce or custody cases filed after July 1, 2026 must start every custody determination with the presumption that equal physical custody (50-50 parenting time split) is appropriate. The court would then consider whether either parent presents sufficient evidence to overcome (rebut) this presumption.
Evidence that could rebut the presumption includes documented domestic violence under Mississippi Code § 93-21-1 et seq., one parent's inability to provide safe housing, substance abuse issues, child abuse or neglect substantiated by the Mississippi Department of Child Protection Services, or evidence that equal time would be logistically impossible due to geographic distance between parents' homes. A parent living 200 miles away in another state, for example, could argue that 50-50 weekly exchanges are not feasible for a school-age child.
The bill also overhauls Mississippi's child support calculation methodology. Currently, Mississippi uses an "income shares" model under Mississippi Code § 43-19-101, which calculates support based on both parents' incomes and the number of overnights each parent has with the child. Under HB 1662's presumed 50-50 arrangement, many parents would see support obligations shift because overnight percentages directly affect support calculations. If both parents have equal time (182.5 overnights each per year), support calculations focus primarily on income disparity rather than custodial time.
Mississippi becomes the sixth state to adopt this approach. Kentucky enacted similar legislation in 2018 (KRS § 403.270), Arkansas in 2021 (Ark. Code § 9-13-101), Missouri in 2023 (Mo. Rev. Stat. § 452.375), and West Virginia in 2024 (W. Va. Code § 48-9-206). Florida passed its version in March 2023 (Fla. Stat. § 61.13). Early data from Kentucky shows approximately 42% of custody cases result in equal or near-equal parenting time since the presumption took effect, compared to 28% before the law changed.
What Mississippi Parents Should Know Before July 1, 2026
First, existing custody orders are not automatically modified by HB 1662. If you have a custody order entered before July 1, 2026, that order remains in effect unless you file a motion to modify custody under Mississippi Code § 93-5-24. However, if you file for modification after July 1, 2026, courts will apply the new 50-50 presumption to your case.
Second, parents filing for divorce or initial custody determinations after July 1, 2026 should prepare for negotiations to center around equal time as the starting point. If you believe equal custody would not serve your child's best interest, document your reasons now. Gather evidence such as work schedules showing you are available for school drop-offs and the other parent works night shifts, medical records if the other parent has untreated substance abuse issues, school records showing stability in your home, or documentation of domestic violence incidents.
Third, understand that "50-50 custody" does not always mean alternating weeks. Courts can order various equal-time schedules: alternating weeks, 2-2-3 rotations (two days with Parent A, two days with Parent B, three days with Parent A, then flip), or even alternating months for older children. The key is approximately 182.5 overnights per year with each parent.
Fourth, child support calculations will change significantly under the new framework. If you currently pay support based on having less parenting time, moving to 50-50 custody could reduce your obligation substantially. Conversely, if you receive support and the other parent moves to equal time, your support amount may decrease. Consult a Mississippi family law attorney to run projected calculations under the new law before agreeing to modifications.
Fifth, Governor Reeves has three options by April 13, 2026: sign the bill into law, veto it (which the legislature could override with a two-thirds vote), or take no action and allow it to become law without his signature after the deadline. As of this writing, the governor has not publicly stated his position on HB 1662.
Frequently Asked Questions
Does HB 1662 apply to custody cases already in progress?
HB 1662 applies to any custody determination finalized on or after July 1, 2026. If your divorce or custody case is pending as of July 1, 2026 but not yet finalized, Mississippi courts will apply the new 50-50 presumption when issuing the final custody order. Cases completely finalized before July 1, 2026 are governed by the old standard unless one parent files a modification petition after the effective date.
Can I still get sole custody if I can prove the other parent is unfit?
Yes. The 50-50 presumption is rebuttable, meaning you can overcome it with sufficient evidence. Documented domestic violence under Mississippi Code § 93-21-1, substantiated child abuse or neglect, untreated severe mental illness, active substance abuse, or incarceration are all grounds to rebut the presumption. You must present clear and convincing evidence that equal custody would harm the child, not merely that sole custody would be preferable.
How does this affect child support if we already have a 60-40 custody split?
If you have an existing 60-40 custody arrangement and do not modify it, your current child support order remains unchanged. However, if either parent files a motion to modify custody after July 1, 2026, the court will apply the 50-50 presumption. If custody changes to equal time, Mississippi's income shares model under Mississippi Code § 43-19-101 recalculates support based primarily on income disparity rather than custodial time percentages, typically reducing the higher earner's support obligation by 30-50% compared to a 60-40 split.
What if we live in different school districts 45 miles apart?
Geographic distance can rebut the 50-50 presumption if you demonstrate that equal parenting time would disrupt the child's education or extracurricular activities. Courts consider whether alternating weeks would require switching schools mid-year, excessive commute times for the child, or whether the child would miss important activities. A 45-mile distance (approximately 60-75 minutes driving time) may or may not rebut the presumption depending on the child's age, school schedule, and each parent's flexibility to transport.
Can we agree to a different custody arrangement instead of 50-50?
Yes. HB 1662 establishes a presumption for contested cases where parents cannot agree. If both parents negotiate a different custody schedule and the court finds it serves the child's best interest, judges can approve alternative arrangements. Many Mississippi custody cases settle through mediation under Mississippi Code § 93-5-24 without trial, and negotiated agreements are typically approved if reasonable. The 50-50 presumption applies when parents litigate custody and ask a judge to decide.
What This Means for Mississippi Families Going Forward
If Governor Reeves signs HB 1662 or allows it to become law, Mississippi joins a growing number of states recognizing that children generally benefit from substantial time with both parents after divorce. The practical impact will depend on how Mississippi chancery courts interpret "rebuttable presumption" and what evidence they deem sufficient to overcome it.
Parents considering divorce or custody modifications should consult a Mississippi family law attorney before July 1, 2026 to understand how the new law affects their specific situation. Those with safety concerns should document incidents now and explore protective orders under Mississippi Code § 93-21-1 if necessary.
The next two weeks will determine whether this bill becomes law. Watch for Governor Reeves' announcement before the April 13, 2026 deadline.
