Mississippi HB 1662: 50-50 Joint Custody Presumption Effective July 1, 2026

Mississippi Governor Tate Reeves signed House Bill 1662 on April 8, 2026, creating a rebuttable presumption that joint custody with equal (50-50) parenting time serves a child's best interest. Effective July 1, 2026, the law makes Mississippi the 6th state with a shared-parenting presumption and replaces the 40-year-old Albright factor test for new custody filings.

Key Facts

According to Mississippi Today, HB 1662 cleared both chambers of the Legislature before reaching the Governor's desk. The bill reframes the legal starting point for custody disputes: instead of a judge weighing factors from scratch, courts now begin with the assumption that equal parenting time is best, and a parent must present evidence to overcome that presumption.

Why this matters legally

HB 1662 shifts the burden of proof in Mississippi custody cases. Before July 1, 2026, chancery courts applied the Albright v. Albright factors — the 1983 Mississippi Supreme Court framework listing 12+ considerations (age, health, parenting continuity, stability, employment, moral fitness, home environment) with no thumb on the scale toward either parent. Under the new law, courts start from a presumption of 50-50, and the parent opposing equal time carries the burden of rebutting it with evidence that shared time harms the child.

This is a structural change, not a cosmetic one. A rebuttable presumption alters what each side must prove and often influences settlement negotiations before a case ever reaches trial. Parents who previously fought for "primary" custody now start from a legal baseline of equal division of parenting time. The practical effect is that fewer cases will default to one parent as the primary custodian without a factual showing.

Importantly, the presumption is rebuttable, not absolute. Judges retain discretion to order unequal time when the evidence shows equal time is not in the child's best interest. The law does not guarantee any parent a 50-50 outcome; it changes the default and reassigns the burden.

How Mississippi law handles this

Mississippi custody law lives primarily in Miss. Code Ann. § 93-5-24, which governs joint custody and defines the forms of legal and physical custody available in divorce and separate-maintenance actions. HB 1662 amends this framework by inserting the equal-parenting-time presumption into the analysis that chancery courts previously conducted purely under the Albright best-interest factors.

The statute continues to distinguish joint legal custody (shared decision-making on major issues like education, health care, and religion) from joint physical custody (how the child's time is divided between homes). Under Miss. Code Ann. § 93-5-23, chancery courts retain broad authority over custody, support, and the care of minor children in divorce proceedings. HB 1662 does not remove that authority — it channels it through a new starting presumption.

The law also shifts child support toward an income-comparison approach. Mississippi has historically calculated support under Miss. Code Ann. § 43-19-101, which sets guideline percentages of a non-custodial parent's adjusted gross income (14% for one child, 20% for two, 24% for three, 26% for four, 28% for five or more). When parenting time is genuinely equal, a straight percentage-of-one-parent's-income model fits poorly, so the new approach compares both parents' incomes to allocate support more proportionally.

The domestic-violence carve-out is critical. Where a domestic abuse protection order exists, the 50-50 presumption does not apply. This aligns with longstanding Mississippi policy under Miss. Code Ann. § 93-5-24 that a history of family violence weighs heavily against shared custody arrangements, protecting children and survivors from being forced into equal-time schedules with an abusive parent.

Practical takeaways

1. Timing determines which rule applies. Custody and divorce filings submitted on or after July 1, 2026, start from the 50-50 presumption. Cases already pending before that date generally continue under the Albright analysis unless a court directs otherwise, so confirm your filing date with counsel.

2. Build your evidence to the new standard. If you believe equal time is not appropriate, gather specific, documented evidence — school records, medical records, communication logs, work-schedule conflicts — because you now carry the burden of rebutting the presumption rather than simply arguing best interest.

3. Reassess child support expectations. Because support is moving toward an income-comparison model in equal-time cases, run updated estimates. Use our Mississippi child support calculator and parenting time calculator to model realistic scenarios before negotiations.

4. Document domestic-violence concerns properly. The presumption does not apply where a domestic abuse protection order exists. If safety is a concern, speak with an attorney or advocate about obtaining a protective order, which materially changes the custody analysis.

5. Draft a detailed parenting plan. Equal time requires a workable logistics plan — exchange schedules, holidays, transportation, and decision-making rules. Learn how parenting plans and child custody arrangements work in practice, and map your next steps with a personalized divorce roadmap.

HB 1662 is one of the most significant changes to Mississippi custody law in four decades, and its real-world impact will unfold as chancery courts apply the new presumption after July 1, 2026.
