Legal Situations That Require Court-Admissible DNA Testing

California courts recognize DNA testing as a key tool in establishing parentage, and Los Angeles Superior Court family law proceedings regularly require officially documented results. At-home DNA kits don’t meet chain-of-custody standards and aren’t accepted by California courts or agencies for legal purposes. Only testing performed by certified collectors at an accredited facility qualifies.

We handle court admissible DNA testing for a wide range of legal matters, including:

• Establishing or confirming legal parentage in paternity or maternity cases
• Custody and visitation disputes before Los Angeles Superior Court
• Child support determinations and inheritance claims
• Legal guardianship and adoption proceedings
• Probate and estate cases requiring biological relationship evidence
• Immigration DNA testing for USCIS visa and residency applications when other documentation is incomplete
• Government and military benefits eligibility confirmation
• Relationship DNA testing, including sibling, grandparent, and avuncular (aunt or uncle) testing when a biological parent is unavailable

When a parent can’t be tested, California family law and immigration proceedings may require relationship DNA testing to establish biological ties for custody, support, or inheritance purposes. Sibling, grandparent, and avuncular tests each approach the question differently, and our team can help clarify which applies to your situation. For immigration matters, accepted test types are determined on a case-by-case basis by USCIS or a consular officer.
