Mississippi Governor Must Decide on 50-50 Custody Bill by April 13, 2026
Mississippi House Bill 1662 now sits on Governor Tate Reeves' desk with an April 13, 2026 signing deadline. If enacted, the bill creates a rebuttable presumption of equal (50-50) parenting time in all custody disputes, making Mississippi the sixth state nationwide to adopt mandatory joint custody presumption. The new law would take effect July 1, 2026, fundamentally changing how Mississippi courts approach custody and child support calculations.

What HB 1662 Changes Under Mississippi Law
Mississippi currently operates under the Albright factors framework established in Albright v. Albright, 437 So.2d 1003 (Miss. 1983), which requires courts to weigh 12 factors when determining custody. Under this existing standard, courts have no presumption favoring either parent and make individualized determinations based on the child's best interest.
HB 1662 fundamentally restructures this approach by establishing that Mississippi courts must presume equal parenting time (50-50) serves the child's best interest. This presumption can only be overcome by clear and convincing evidence that equal time would harm the child.
The bill also introduces a new child support calculation method. Under the proposed formula, both parents' incomes are combined, and the higher-earning parent pays the difference in child support obligations to the lower-earning parent. This represents a significant departure from Mississippi's current child support guidelines under Miss. Code Ann. § 43-19-101, which calculate support based primarily on the non-custodial parent's income.
Why This Legislation Matters for Mississippi Families
Mississippi would join Kentucky, Arizona, Arkansas, West Virginia, and Florida as states with statutory presumptions favoring equal parenting time. Kentucky's 2017 joint custody presumption law (the first in the nation) has been studied extensively, with researchers finding a 15% reduction in custody litigation within three years of implementation.
The practical impact for Mississippi families is substantial. Parents currently spend an average of $15,000-$30,000 on contested custody litigation in Mississippi courts. A rebuttable presumption starting point of 50-50 could reduce these costs by establishing a baseline expectation.
However, the bill has drawn criticism from domestic violence advocates and family law practitioners who argue that equal time presumptions may not account for cases involving abuse, addiction, or significant parenting capacity differences. The Mississippi Coalition Against Domestic Violence has expressed concerns that victims may face additional barriers when seeking protective custody arrangements.
How Mississippi Courts Would Apply the New Standard
If Governor Reeves signs HB 1662, Mississippi judges would begin all custody determinations with a 50-50 parenting time presumption effective July 1, 2026. Parents seeking a different arrangement would need to present clear and convincing evidence that equal time is not in the child's best interest.
The clear and convincing standard represents a middle ground between the preponderance of evidence standard (more likely than not) and the beyond reasonable doubt standard used in criminal cases. Mississippi courts define clear and convincing evidence as proof that produces a firm belief or conviction that the allegations are true.
Factors that could rebut the presumption include documented domestic violence, substance abuse affecting parenting capacity, geographical distance making equal time impractical, or evidence that a parent has historically been uninvolved in the child's daily care.
The Albright factors would remain relevant for courts determining how to structure parenting time when the presumption is rebutted, but they would no longer be the primary framework for initial custody determinations.
Child Support Calculation Changes Explained
The bill's child support provision represents equally significant reform. Under current Mississippi guidelines, the non-custodial parent typically pays 14% of adjusted gross income for one child, 20% for two children, and 22% for three children, with caps and adjustments based on income levels.
HB 1662's income-sharing model works differently. Both parents' incomes are combined to determine total available support. Each parent's proportionate share is calculated based on their percentage of combined income. The higher-earning parent then pays the difference between the two obligations to the lower-earning parent.
For example, if Parent A earns $80,000 annually and Parent B earns $40,000 annually, their combined income is $120,000. Parent A represents 67% of the combined income, while Parent B represents 33%. If the calculated child support obligation is $1,500 monthly, Parent A's share would be $1,000 and Parent B's share would be $500. Parent A would pay the $500 difference to Parent B.
This model more closely aligns with the income shares approach used in 41 states, though Mississippi's version is specifically designed for equal parenting time arrangements.
Practical Takeaways for Mississippi Parents
-
Parents with pending custody cases should discuss with their attorneys how HB 1662 might affect their case strategy if signed before July 1, 2026.
-
Parents currently paying or receiving child support under existing orders should anticipate potential modification requests if the new calculation method significantly changes obligations.
-
Co-parents with existing custody agreements are not automatically affected, but either parent could petition for modification under the new standard after July 1, 2026.
-
Parents concerned about safety issues should document any evidence of domestic violence, substance abuse, or other factors that would support rebutting the presumption.
-
Both parents should prepare financial documentation, as the new child support calculation requires detailed income verification from both parties.
What Happens If the Governor Does Not Act
Under Mississippi Constitution Article 4, Section 73, the Governor has five days (excluding Sundays) after receiving a bill to sign it, veto it, or allow it to become law without signature. If Governor Reeves takes no action by April 13, 2026, HB 1662 becomes law automatically.
The Governor can also issue a partial veto, though this is less common with substantive legislation. A full veto would return the bill to the legislature, where a two-thirds majority in both chambers would be required to override.
Given the bill's bipartisan passage margins, advocates believe an override is possible if the Governor vetoes. However, the legislative session calendar may affect whether an override vote could occur before the session ends.
Frequently Asked Questions
Does HB 1662 guarantee 50-50 custody in Mississippi?
No, HB 1662 creates a rebuttable presumption of 50-50 parenting time, not a guarantee. Either parent can present clear and convincing evidence that equal time is not in the child's best interest, and courts retain discretion to order different arrangements when the presumption is successfully rebutted.
When would the new Mississippi custody law take effect?
If Governor Reeves signs HB 1662 or allows it to become law without signature by April 13, 2026, the new custody presumption and child support calculation method take effect July 1, 2026. Cases filed after that date would be subject to the new standard.
Can I modify my existing Mississippi custody order under the new law?
Yes, after July 1, 2026, either parent can petition for modification of existing custody orders. However, Mississippi courts still require a material change in circumstances to modify custody. The new law itself may constitute sufficient changed circumstances for modification petitions.
How does HB 1662 affect child support calculations in Mississippi?
The bill replaces Mississippi's percentage-of-income model with an income shares approach. Both parents' incomes are combined, each parent's proportionate share is calculated, and the higher-earning parent pays the difference to the lower-earning parent. This typically results in different support amounts than current guidelines.
What if there is domestic violence in my Mississippi custody case?
Documented domestic violence can rebut the 50-50 presumption under HB 1662. Parents with safety concerns should maintain records of protective orders, police reports, and other evidence. Courts retain authority to limit parenting time or order supervised visitation when necessary to protect children.
