Primary vs. Joint Custody Explained: Lessons From the Kimora Lee Simmons Case
▶ Watch Attorney Judith Delus Montgomery on TMZ Live (YouTube)
When a celebrity divorce makes headlines, the legal terms fly fast — primary custody, joint custody, legal custody, physical custody — and most parents are left unsure what any of it actually means. Atlanta family law attorney Judith Delus Montgomery recently joined TMZ Live to make sense of one such story: the custody matter in the divorce between fashion mogul Kimora Lee Simmons and former Goldman Sachs banker Tim Leissner.
The case is a useful teaching moment for any parent — not because of the celebrity names, but because of what it reveals about how custody really works and how easily a court filing can be misread. Here is a plain-English breakdown from a child custody attorney in Georgia, using the headlines as our guide.
What the Kimora Lee Simmons Custody Case Is About
Kimora Lee Simmons and Tim Leissner, who share an 11-year-old son, are ending a 12-year marriage. After Leissner filed for divorce and requested joint custody, Simmons filed her response — and a widely reported detail suggested she was asking for Leissner to have primary legal and physical custody instead.
That report didn’t sit right, and for good reason. Simmons quickly clarified that the “primary custody” entry was a clerical error — she has no plans to give up primary custody of her son. Adding important context, Leissner is currently serving a two-year federal prison sentence tied to the 1MDB financial scandal, which makes a primary physical custody arrangement for him a practical impossibility.
The real lesson isn’t the celebrity drama — it’s how easily a single entry on a court filing can create confusion, and why precision in custody paperwork matters so much. The filing becomes the legal record, whatever the parties actually intend.
Legal Custody vs. Physical Custody
These two terms are the foundation of every custody arrangement, and they are not the same thing. For a fuller overview, see our guide to child custody laws in Georgia.
• Legal custody is the right to make major decisions about a child’s life — education, healthcare, religion, and general welfare.
•
Physical custody
is where the child actually lives and spends time day to day.
A parent can share one without the other. It’s common, for example, for parents to share joint legal custody (both weigh in on big decisions) while one parent has primary physical custody (the child lives mainly with them).
Primary Custody vs. Joint Custody
•
Joint custody
means the parents share — either decision-making authority (joint legal), living time (joint physical), or both. It reflects an intent to keep both parents actively involved.
• Primary custody means one parent holds the larger share, while the other typically has visitation or parenting time.
In the celebrity case above, the tension was clear: Leissner asked for joint custody, while the filing appeared — mistakenly — to hand him primary custody. That’s the difference between “we co-parent this child together” and “this child primarily lives with, and is primarily decided for, by one parent.”
How Georgia Courts Decide Custody
No matter what the parents request, a Georgia court’s guiding standard is the best interests of the child. Judges weigh factors such as:
• Each parent’s relationship with and history of caring for the child.
• The child’s need for stability, safety, and continuity.
• Each parent’s ability to meet the child’s emotional, educational, and physical needs.
• Each parent’s willingness to support the child’s relationship with the other parent.
This is why what a parent writes on a form and what a court ultimately orders can differ. The filing opens the conversation; the evidence and the child’s best interests drive the outcome.
What Attorney Montgomery Highlighted on TMZ Live
On air, Montgomery zeroed in on why the initial report was so striking — the possibility that a mother who had been her son’s constant caregiver would hand primary custody to the other parent: “It is really interesting to hear that it’s not just the custody request — it’s that she would even consider giving him primary legal or physical custody of their son, when the relationship has always been her and her son.”
As the case was later clarified, that scenario reflected a filing error rather than Simmons’s intent — a reminder that what appears on paper drives the legal record, whatever the parties actually mean to say.
Conclusion
Custody decisions shape a child’s daily life for years, and — as this high-profile case shows — even the paperwork deserves careful attention. Understanding the difference between legal and physical, primary and joint custody is the first step to protecting what matters most.

Legal custody is the authority to make major decisions for a child — education, healthcare, and religion. Physical custody determines where the child lives day to day. Parents can share one without sharing the other.
What does “primary custody” mean?
Primary custody means one parent holds the larger share of custody — of decision-making, living time, or both — while the other parent typically has visitation or parenting time.
Did Kimora Lee Simmons actually give Tim Leissner primary custody?
No. A widely reported filing suggested she asked for Leissner to have primary custody, but Simmons clarified it was a clerical error. Leissner had requested joint custody and is currently serving a federal prison sentence.
How do Georgia courts decide custody?
Georgia courts apply the “best interests of the child” standard, weighing each parent’s caregiving history, the child’s need for stability, each parent’s ability to meet the child’s needs, and each parent’s willingness to support the child’s bond with the other parent.
