Mississippi Governor Tate Reeves allowed House Bill 1662 to become law on April 13, 2026, establishing a rebuttable presumption of 50-50 joint custody and equal parenting time in all custody proceedings. The law passed the House 118-0 and takes effect July 1, 2026, making Mississippi the 7th state to adopt mandatory joint custody presumption and fundamentally changing how courts approach parenting arrangements in divorce cases.

Why This Matters Legally
Mississippi courts will now start every custody case with the assumption that children benefit from equal time with both parents. Before HB 1662, Mississippi judges had broad discretion under the Albright factors established in Albright v. Albright, 437 So. 2d 1003 (Miss. 1983), which created a 12-factor balancing test without any presumption favoring either parent or any particular custody arrangement.
The new law shifts the burden of proof. Previously, a parent seeking joint custody had to affirmatively demonstrate why equal time served the child's best interests. Starting July 1, 2026, any parent opposing 50-50 custody must present clear evidence showing why equal parenting time would harm the child.
This represents the most significant change to Mississippi custody law in over 40 years. The Albright factors remain relevant for determining how to implement joint custody and for cases where the presumption is rebutted, but they no longer serve as the starting point for custody determinations.
How Mississippi Law Handles Custody After HB 1662
Under the new framework, Miss. Code Ann. § 93-5-24 will require courts to apply a three-step analysis in every custody case.
First, the court presumes that joint legal and physical custody with substantially equal parenting time serves the child's best interests. This presumption applies regardless of whether the parents were married, whether they agree on custody, or which parent files first.
Second, either parent may rebut the presumption by presenting evidence of specific circumstances that make equal time contrary to the child's welfare. The statute identifies factors that can overcome the presumption, including documented domestic violence, substance abuse, child abuse or neglect, a parent's incarceration, or a parent's inability to provide adequate care.
Third, if the presumption is rebutted, courts then apply the traditional best-interests analysis, including the Albright factors, to determine an appropriate custody arrangement.
The law does not require exactly 168 hours divided equally every two weeks. Courts retain flexibility to structure parenting schedules that achieve substantially equal time while accounting for school schedules, parents' work obligations, and geographic considerations. A schedule providing one parent 55% of overnights and the other 45% would likely satisfy the substantially equal standard.
Practical Implications for Mississippi Families
Families with existing custody orders are not automatically affected. The law applies prospectively to cases filed on or after July 1, 2026. Parents with final custody orders entered before that date continue under their existing arrangements unless they file a modification petition.
For divorces filed after July 1, 2026, both parents should expect courts to order joint custody unless specific evidence justifies a different arrangement. This changes litigation strategy significantly. Parents who previously expected to receive primary custody based on being the historical primary caregiver will now need to demonstrate why equal time would harm the child rather than simply why they have been more involved in daily care.
Child support calculations will also change in many cases. Mississippi uses the income shares model under Miss. Code Ann. § 43-19-101, which adjusts support obligations based on each parent's percentage of parenting time. When parents share custody equally, the higher-earning parent typically pays the lower-earning parent a reduced support amount compared to sole custody arrangements.
What Parents Should Do Now
-
Review your current parenting arrangement if you have an existing order and believe circumstances have changed substantially since July 1, 2026 modifications may be evaluated under the new presumption.
-
Document your involvement in your children's daily lives, including school events, medical appointments, extracurricular activities, and daily routines. Equal involvement supports equal time under the new framework.
-
Consider mediation before litigation. With both parents starting from a presumption of equal time, negotiating a workable schedule often proves more efficient than litigating over small percentage differences.
-
If you have legitimate concerns about the other parent's ability to safely care for your children, gather documentation now. Medical records, police reports, school records, and witness statements become critical evidence for rebutting the presumption.
-
Consult with a Mississippi family law attorney before July 1, 2026 if you anticipate filing for divorce or custody modification. The strategic landscape changes significantly under the new law.
What HB 1662 Does Not Change
The new law does not eliminate judicial discretion in custody matters. Judges retain authority to order unequal custody arrangements when evidence supports that decision. The law creates a starting point, not a mandatory outcome.
Relocation rules remain unchanged. A parent seeking to move with a child must still obtain court approval or the other parent's consent under Miss. Code Ann. § 93-5-23.
The law does not affect grandparent visitation rights, which continue under Miss. Code Ann. § 93-16-3.
Existing protective orders and findings of domestic violence continue to carry significant weight. Courts cannot ignore documented abuse simply because the law now presumes equal custody.
FAQs
Does HB 1662 automatically change my existing custody order?
No, HB 1662 applies only to cases filed on or after July 1, 2026. Existing custody orders remain in effect. Parents seeking modification must file a petition and demonstrate a material change in circumstances under Miss. Code Ann. § 93-5-24, though courts will apply the new presumption when evaluating proposed modifications.
Can I still get primary custody if I was my child's primary caregiver?
Being the primary caregiver no longer guarantees primary custody after July 1, 2026. To overcome the 50-50 presumption, you must present evidence that equal parenting time would harm your child. Historical caregiving arrangements remain relevant but are not sufficient alone to rebut the presumption.
How will 50-50 custody affect my child support obligation?
Mississippi's income shares formula reduces support obligations when parents share custody equally. Under Miss. Code Ann. § 43-19-101, the higher-earning parent typically pays the difference between each parent's proportionate share. Equal custody can reduce support by 30-50% compared to sole custody arrangements.
What evidence can rebut the 50-50 presumption?
Courts accept evidence of domestic violence, substance abuse, child abuse or neglect, mental health issues affecting parenting capacity, incarceration, or a parent's demonstrated inability to provide appropriate care. Documentation from medical providers, law enforcement, schools, or child protective services carries significant weight. General claims of being a better parent without specific evidence of harm will not rebut the presumption.
Does the new law apply to unmarried parents?
Yes, HB 1662 applies to all custody determinations regardless of whether the parents were married. Unmarried fathers must first establish paternity under Miss. Code Ann. § 93-9-9, but once paternity is established, the 50-50 presumption applies equally to married and unmarried parents.
