When does Mississippi's 50-50 custody law take effect?

Mississippi's HB 1662 takes effect July 1, 2026. It amends Miss. Code § 93-5-24 to create a rebuttable presumption of equal 50-50 joint physical custody, replacing the discretionary 12-factor Albright v. Albright analysis that governed custody since 1983.

Does HB 1662 guarantee both parents get equal custody?

No. HB 1662 creates a rebuttable presumption, not a guarantee. Courts start with 50-50 as the default, but a parent can overcome it with evidence of abuse, neglect, instability, or unavailability. The child's best interest under the Albright factors still guides the final decision.

How does the new law affect Mississippi child support?

Equal parenting time can lower child support because Mississippi guidelines weigh the non-custodial parent's income and time-share. A higher-earning parent who obtains 50-50 time under HB 1662 may see a reduced obligation. Critics warn this could let higher earners cut payments by claiming equal time.

What was the Albright standard the new law replaces?

Albright v. Albright, 437 So. 2d 1003 (Miss. 1983), established 12 best-interest factors — including health, continuity of care, parenting skills, and moral fitness — that chancellors weighed to decide custody. HB 1662 replaces that discretionary default with a 50-50 presumption starting July 1, 2026.

Could HB 1662 be challenged in court?

Yes. Eight attorneys and former chancery judges argue the law may conflict with the Mississippi Constitution's grant of jurisdiction to chancery courts, per Mississippi Today. Expect early appeals testing whether a legislative custody presumption improperly limits chancellors' constitutional discretion after July 1, 2026.

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

As of July 1, 2026, Mississippi courts must begin every contested custody case with a rebuttable presumption of equal 50-50 parenting time under HB 1662, which amends Miss. Code § 93-5-24. The law replaces the discretionary 12-factor Albright v. Albright analysis that has governed Mississippi custody since 1983, shifting the burden onto the parent who wants an unequal split.

Why this matters legally

HB 1662 reverses more than four decades of Mississippi custody doctrine by making equal parenting time the legal starting point rather than the discretionary result of a best-interest analysis. Since the Mississippi Supreme Court decided Albright v. Albright, 437 So. 2d 1003 (Miss. 1983), chancellors weighed 12 factors — health, continuity of care, parenting skills, employment, moral fitness, and more — to determine what arrangement served the child. Under the amended Miss. Code § 93-5-24, the court now presumes a 50-50 split is best, and a parent who wants primary custody must produce evidence to overcome that presumption.

That is a meaningful procedural change, not a cosmetic one. Presumptions control who bears the burden of proof, and burden allocation frequently decides close cases. According to Mississippi Today, eight family-law attorneys and former chancery judges warned the legislature that the presumption could harm vulnerable parents, allow higher-earning parents to reduce child support obligations by claiming equal time, and may conflict with the Mississippi Constitution's grant of jurisdiction to chancery courts.

How Mississippi law handles this

Mississippi custody law now operates on a rebuttable presumption model under Miss. Code § 93-5-24, replacing the pure discretionary standard that Albright established. A rebuttable presumption means the court assumes 50-50 custody is appropriate unless a parent presents sufficient evidence — such as documented abuse, neglect, instability, or a parent's unavailability — to justify a different arrangement. The child's best interest remains the guiding principle, but the road to an unequal split now runs uphill.

The Albright factors themselves are not erased. Chancellors will likely continue citing them as the evidentiary framework a parent uses to rebut the presumption. In practice, a parent seeking more than half the parenting time must show why the Albright factors point away from equal time in that specific family. This mirrors a national trend: several states, including Kentucky in 2018, have adopted equal-parenting presumptions, though outcomes vary widely by how courts define "rebuttable."

One unresolved question is constitutional. Mississippi's constitution vests full jurisdiction over divorce and custody matters in the chancery courts, and critics quoted by Mississippi Today argue that a legislative presumption may improperly constrain the discretion that constitutional grant implies. Expect early appeals testing whether the presumption survives that challenge. Until the Mississippi Supreme Court rules, chancellors across the state's districts may apply HB 1662 inconsistently.

Child support is the other pressure point. Mississippi calculates support largely on the non-custodial parent's adjusted gross income and the number of children. When parenting time is split evenly, courts may deviate from the standard guideline percentages, which can lower — or occasionally raise — a support obligation. A higher-earning parent who obtains 50-50 time under the new presumption could see a reduced payment even where the lower-earning parent shoulders more day-to-day costs.

Practical takeaways

HB 1662 changes strategy for every Mississippi parent entering a custody dispute after July 1, 2026. Here is what to do:

Document your caregiving now. Because the presumption favors equal time, a parent seeking primary custody must build an evidentiary record — school pickups, medical appointments, the other parent's availability — that rebuts the 50-50 default under the Albright framework.
Understand the burden has shifted. If you want more than half the time, you carry the burden of proof. If you are comfortable with equal time, the presumption now works in your favor. Learn how courts structure these arrangements in our guide to child custody.
Draft a realistic parenting plan. A 50-50 schedule requires logistics — proximity, work hours, school districts — to function. Build a detailed parenting plan and model different schedules with our parenting time calculator.
Reassess child support expectations. Equal time can change support math. Run the numbers early so a settlement offer does not surprise you.
Flag safety concerns immediately. The presumption is rebuttable specifically to protect children from abuse or neglect. If safety is an issue, tell your attorney and preserve documentation; do not assume the 50-50 default will be applied blindly.
Get case-specific guidance. Because chancery courts may interpret HB 1662 differently during the transition, an experienced local attorney's read on your district matters. Start with a personalized divorce roadmap or find a divorce attorney in your county.

If you are navigating a Mississippi custody case as the new presumption takes effect, the shifting burden of proof makes early planning more valuable than ever — mapping your parenting history and your goals now can shape the outcome later.
