Mississippi Poised to Become Sixth State with 50-50 Joint Custody Presumption
Mississippi Governor Tate Reeves has until April 13, 2026 to sign House Bill 1662, legislation that would fundamentally reshape how the state handles child custody cases. If enacted, Mississippi would join Kentucky, Arizona, Arkansas, West Virginia, and Missouri as the sixth state requiring courts to presume equal parenting time is in a child's best interest. The bill, which passed both chambers with bipartisan support, takes effect July 1, 2026 and also overhauls Mississippi's child support calculation method.

What House Bill 1662 Actually Changes
House Bill 1662 establishes a rebuttable presumption that joint physical custody with substantially equal parenting time serves the best interest of the child. Under current Mississippi law codified in Miss. Code Ann. § 93-5-24, courts have broad discretion to determine custody arrangements based on the Albright factors established in the 1983 Mississippi Supreme Court decision Albright v. Albright, 437 So. 2d 1003.
The new law does not guarantee every parent receives 50-50 custody. Instead, it shifts the starting point of custody negotiations and litigation. A parent seeking more than 50% of parenting time must now prove why equal time would not serve the child's best interest. Previously, parents seeking equal time bore this burden of proof.
Mississippi courts will continue applying best-interest-of-the-child analysis, but the presumption creates a default expectation that equal parenting time is appropriate unless evidence demonstrates otherwise. Factors that can rebut the presumption include documented domestic violence, substance abuse, child abuse or neglect, incarceration, geographic distance exceeding 50 miles, and parental unfitness.
How This Transforms Mississippi Child Support Calculations
House Bill 1662 contains a second major reform that received less media attention. Mississippi currently uses a percentage-of-income model under Miss. Code Ann. § 43-19-101, where the non-custodial parent pays a flat percentage of gross income based on the number of children: 14% for one child, 20% for two children, 22% for three children, 24% for four children, and 26% for five or more children.
The bill replaces this formula with an income-shares model used by 41 other states. Income-shares calculates child support by determining the total amount both parents would spend on the child if they lived together, then divides that obligation proportionally based on each parent's income. When parents share equal parenting time, this typically results in lower support obligations because both parents directly incur child-related expenses during their parenting periods.
A Mississippi parent earning $60,000 annually with one child currently pays approximately $700 per month (14% of gross income) in child support regardless of how much parenting time they exercise. Under the income-shares model taking effect July 1, 2026, that same parent with 50% parenting time and an ex-spouse earning $40,000 would likely pay between $200-400 per month, depending on childcare and healthcare costs.
What Mississippi Parents Should Expect
Parents currently navigating custody disputes face a strategic decision. Cases filed before July 1, 2026 proceed under existing law where no presumption exists. Cases filed on or after July 1, 2026 operate under the new presumption favoring equal parenting time.
Parents who previously received less than 50% custody may have grounds to seek modification after July 1, 2026. Mississippi law under Miss. Code Ann. § 93-5-23 requires a material change in circumstances to modify custody orders. Courts across the state will need to determine whether the statutory change itself constitutes sufficient grounds for modification. Early indications from states that enacted similar laws suggest courts generally do not treat the statutory change alone as grounds for modification without additional changed circumstances.
Parents seeking to preserve existing custody arrangements that deviate from 50-50 should document specific reasons why equal time would not serve the child's best interest. Factors courts will consider include each parent's historical involvement in day-to-day caregiving, the child's school and activity schedules, distance between parental homes, each parent's work schedule, and the child's established routines and relationships.
Practical Takeaways for Mississippi Families
-
Review your current custody order now if you have been seeking more parenting time. Consult with a Mississippi family law attorney about whether filing a modification after July 1, 2026 makes strategic sense for your situation.
-
Gather documentation of your parenting involvement if you anticipate a custody dispute. Courts applying the 50-50 presumption still evaluate which parent has historically provided primary caregiving, attended school events, managed medical appointments, and participated in daily routines.
-
Calculate your potential child support obligation under the income-shares model before negotiating settlements. The Mississippi Department of Human Services will publish updated guidelines before the July 1, 2026 effective date.
-
Consider geographic proximity to your co-parent when making housing decisions. The 50-50 presumption becomes practically difficult to implement when parents live more than 50 miles apart or in different school districts.
-
Understand that domestic violence allegations carry significant weight under the new framework. Courts cannot presume equal parenting time where credible evidence of domestic violence exists, and the bill creates specific findings requirements for cases involving protective orders.
Frequently Asked Questions
Does this bill guarantee I will get 50-50 custody of my children?
House Bill 1662 does not guarantee 50-50 custody. The bill creates a rebuttable presumption, meaning courts start with the assumption that equal parenting time serves the child's best interest. Either parent can present evidence demonstrating why a different arrangement would better serve the child. Factors including domestic violence, substance abuse, geographic distance, and parental unfitness can rebut the presumption.
When does the new Mississippi custody law take effect?
The new custody presumption takes effect July 1, 2026, assuming Governor Reeves signs the bill by his April 13, 2026 deadline. Cases filed before July 1, 2026 proceed under existing Mississippi law without any presumption. Cases filed on or after July 1, 2026 operate under the new equal parenting time presumption established by House Bill 1662.
Can I modify my existing custody order under the new law?
Mississippi law under Miss. Code Ann. § 93-5-23 requires a material change in circumstances to modify custody orders. The statutory change alone may not constitute sufficient grounds for modification. Parents seeking modification should consult with a Mississippi family law attorney to evaluate whether additional changed circumstances combined with the new presumption create viable grounds for modification.
How will the income-shares model change my child support payments?
The income-shares model calculates support based on both parents' incomes rather than just the paying parent's income. Parents with equal parenting time typically see reduced support obligations because both parents directly incur child-related expenses during their parenting periods. A parent currently paying 14% of gross income for one child might see obligations reduced by 40-70% under income-shares with 50-50 custody, depending on the other parent's income.
What happens if I have a domestic violence protective order?
House Bill 1662 explicitly addresses domestic violence. Courts cannot presume equal parenting time where credible evidence of domestic violence exists. A current or past protective order creates a significant hurdle for the accused parent seeking equal custody. The bill requires specific judicial findings before awarding substantial parenting time to a parent with documented domestic violence history.
