A California judge denied Offset's February 25, 2026 request for a court-ordered DNA test on Cardi B's newborn son with NFL star Stefon Diggs (born November 2025), but granted a paternity test for a different child in the divorce proceedings, according to an unsealed order first reported by TMZ. The ruling matters for every California divorce because it applies Family Code § 7540's strict marital presumption of paternity to a high-profile split.

Why This Ruling Matters Legally
The denial reinforces California's conclusive marital presumption of paternity, one of the strongest in the nation. Under Cal. Fam. Code § 7540, a child born to a wife cohabiting with her husband, who is not impotent or sterile, is conclusively presumed to be a child of the marriage. Because Cardi B filed for divorce in 2024 but the divorce was not finalized when her November 2025 child was born, California law creates a strong statutory presumption that must be rebutted within a narrow window.
The judge's split decision — denying one DNA request while granting another — shows how California courts apply § 7540 differently depending on when a child was conceived and born relative to the marriage. A paternity challenge requires the requesting spouse to file a motion within two years of the child's birth under Cal. Fam. Code § 7541, and the court must find that blood testing serves the best interest of the child. That best-interest analysis explains why two similar DNA requests in the same case can produce opposite results.
The mutual gag rule is equally significant. California courts can issue protective orders restricting disparaging public statements under their general equitable authority, but such orders must be narrowly tailored to avoid First Amendment prior-restraint concerns. Gag orders in celebrity divorces have become more common since 2020 as courts balance privacy against public-figure speech rights.
How California Law Handles Paternity Challenges
California's paternity framework operates on three tiers. First, the conclusive marital presumption under Cal. Fam. Code § 7540 treats a husband as the legal father of any child born during the marriage. Second, a rebuttable presumed-parent status under Cal. Fam. Code § 7611 applies when a man receives the child into his home and holds the child out as his own. Third, genetic testing under Cal. Fam. Code § 7551 can establish or disprove biological parentage when the court orders it.
The two-year deadline in Cal. Fam. Code § 7541 is jurisdictional. A husband who does not move to challenge paternity within 24 months of birth loses the right to disclaim legal fatherhood, even if DNA later proves he is not the biological father. For Cardi B's newborn born in November 2025, Offset would have until November 2027 to preserve any paternity challenge — but only if the court finds testing serves the child's best interest.
California also recognizes Voluntary Declarations of Parentage under Cal. Fam. Code § 7573, which establish legal parentage without court proceedings when signed at the hospital. In high-profile cases, voluntary declarations naming a biological father can moot a husband's paternity claim entirely.
Practical Takeaways for California Divorce Clients
-
File paternity motions within 24 months. Under Cal. Fam. Code § 7541, the two-year deadline runs from the child's birth date, not the divorce filing date. Missing this window typically extinguishes the right to challenge paternity.
-
Document separation dates carefully. The marital presumption in Cal. Fam. Code § 7540 weakens when spouses were not cohabiting at conception. Keep lease agreements, utility bills, and travel records showing physical separation.
-
Request genetic testing early. California courts consider best-interest factors including the child's age, existing parent-child bond, and emotional impact. Testing requests filed within months of birth face lower best-interest hurdles than requests filed years later.
-
Prepare for gag orders in high-conflict divorces. Under California's protective-order authority, judges can restrict social media posts, press interviews, and public statements about the divorce. Violations can trigger contempt findings and monetary sanctions under Cal. Fam. Code § 271.
-
Consider the financial stakes of paternity. A legal father owes child support until age 18 (or 19 if still in high school) under Cal. Fam. Code § 3901. For high-income earners, the difference between legal and biological fatherhood can exceed $500,000 over a child's minority.
Frequently Asked Questions
Can a husband demand a DNA test for any child born during marriage in California?
No. California Family Code § 7540 creates a conclusive presumption that a husband is the father of any child born during marriage when the spouses cohabit and the husband is not sterile. A court-ordered DNA test requires a motion filed within two years of the child's birth under Cal. Fam. Code § 7541, and the court must find testing serves the child's best interest.
What happens if a paternity challenge misses the two-year deadline?
The challenge is barred. California's two-year deadline in Cal. Fam. Code § 7541 is jurisdictional, meaning courts cannot extend it even for compelling reasons. A husband who misses the 24-month window from birth remains the legal father, owes child support until the child turns 18, and retains custody rights under Cal. Fam. Code § 3040.
Are gag orders enforceable in California divorce cases?
Yes, but they must be narrowly tailored. California courts can issue protective orders restricting disparaging public statements, particularly when social media posts harm minor children. Violations can trigger contempt findings, attorney-fee sanctions under Cal. Fam. Code § 271, and in extreme cases, custody modifications. Orders restricting all speech about the divorce typically fail First Amendment review.
How does separation affect the California marital presumption of paternity?
Separation weakens but does not eliminate the presumption. Under Cal. Fam. Code § 7540, the conclusive presumption applies only when spouses cohabit at conception. A spouse challenging paternity must prove non-cohabitation during the 266 days before birth (the typical gestation period). Documented separation dates, separate residences, and travel records are critical evidence.
What is the difference between biological and legal fatherhood in California?
Legal fatherhood creates support obligations and custody rights regardless of biology. Under Cal. Fam. Code § 7611, a man can become a presumed legal parent by receiving a child into his home and holding the child out as his own, even without a biological connection. Legal fathers owe child support until age 18 under Cal. Fam. Code § 3901 and retain custody rights unless paternity is timely disproved.
