On July 21, 2026, Kimora Lee Simmons filed a formal response disputing imprisoned ex-husband Tim Leissner's request for joint legal and physical custody of their son Wolfe, according to Atlanta Black Star and TMZ. For California parents, the case spotlights how courts weigh a parent's incarceration under the best-interest standard in Cal. Fam. Code § 3011.

Because the couple married in 2014 and legally separated in 2022, the marriage spanned roughly eight years before separation — a period California treats as significant when dividing community property and evaluating parenting history. The custody dispute is now the central contested issue, moving the case from an uncontested filing toward litigation.
Why this matters legally
A parent's incarceration does not automatically terminate custody rights, but California courts weigh it heavily under the best-interest standard. Under Cal. Fam. Code § 3011, a judge must consider the health, safety, and welfare of the child, any history of abuse, the nature of each parent's contact with the child, and habitual substance abuse. An incarcerated parent's inability to provide day-to-day physical care directly affects the physical custody analysis, even when legal custody (decision-making authority) may still be shared.
The distinction between legal and physical custody is decisive here. Cal. Fam. Code § 3003 defines joint legal custody as shared authority over decisions about health, education, and welfare, while Cal. Fam. Code § 3004 defines joint physical custody as significant periods of physical time with each parent. A parent behind bars can theoretically retain joint legal custody — participating in decisions by phone or mail — but joint physical custody is practically impossible during incarceration. That gap is exactly what Simmons's disputed response targets. Learn more about child custody arrangements and how courts separate these two forms of authority.
How California law handles this
California applies a gender-neutral best-interest analysis and does not presume either parent is superior. Cal. Fam. Code § 3040 directs courts to grant custody according to the child's best interest and the policy of ensuring frequent and continuing contact with both parents — but that policy yields when contact would not serve the child's welfare. An incarcerated parent's petition for joint physical custody typically converts into a request for a structured visitation or contact schedule rather than shared residential time.
Courts also examine the length and quality of the parent-child relationship before incarceration. Because Leissner and Simmons separated in 2022 and he is now imprisoned, a California judge would scrutinize how much active parenting time he had with Wolfe both before and after separation. When parents cannot agree, Cal. Fam. Code § 3170 requires mediation through Family Court Services before a contested custody hearing, and the court may order a custody evaluation under Cal. Fam. Code § 3111 to produce a professional recommendation.
On the financial side, both legal and physical custody percentages feed directly into California's statewide child support guideline. The guideline formula counts each parent's timeshare, so a parent with little or no physical custody generally pays support based on the higher-earning parent's income and the near-total timeshare of the custodial parent. California parents can estimate obligations with a child support calculator and model parenting time using a parenting-time calculator.
Practical takeaways
-
Separate the two custody questions. If you are litigating against an incarcerated or unavailable co-parent, ask specifically whether you are disputing legal custody (decision-making) or physical custody (residential time) — California treats them under different statutes, § 3003 and § 3004.
-
Document the parenting history. Courts weigh who actually cared for the child before the dispute. Keep records of school pickups, medical appointments, and daily caregiving, because Cal. Fam. Code § 3011 requires the judge to evaluate the nature of each parent's contact with the child.
-
Expect mediation first. Under Cal. Fam. Code § 3170, contested custody matters go to mandatory Family Court Services mediation before a judge decides. Prepare a proposed parenting plan rather than walking in without one.
-
Consider a custody evaluation. When a parent's fitness or availability is in question, either side can request an evaluation under Cal. Fam. Code § 3111. The resulting report often shapes the final order.
-
Map your financial exposure. Because timeshare drives the child support guideline, run the numbers early. A divorce cost estimator and a personalized divorce roadmap can help you plan next steps before the contested hearing.
