In re Charles W. CA4/1, D078574

Three minor children (Charles W. Jr., S.W., and newborn R.W.) became subjects of a juvenile dependency after parents were arrested for drug-related offenses and drugs accessible to the children were found.
A 2019 dependency involving the two older children resulted in a prior juvenile-court finding that ICWA did not apply.
At intake for the new matter Mother initially reported Yaqui and Aztec heritage; Agency completed ICWA-010(A) and a field worksheet (which also listed a “Sioux” notation) and the court ordered further ICWA inquiry.
At the December 28 hearing Mother was present remotely; her counsel twice represented that Mother had no Native American ancestry and no change in information from the prior proceeding; Father denied Indian heritage.
The juvenile court found ICWA does not apply (stating the finding was "without prejudice"). Father appealed, arguing the Agency and court failed to make sufficient ICWA inquiry into Mother’s ancestry.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the juvenile court/Agency made sufficient ICWA inquiry into Mother’s ancestry before finding ICWA does not apply	Agency/respondent: prior court finding + counsel's representation that Mother has no Native ancestry sufficed; no reason to believe the children are Indian	Father/appellant: inquiry was inadequate because the Agency’s worksheet noted a possible "Sioux" affiliation and the court should have directly questioned Mother or pursued further investigation	Court affirmed: inquiry was adequate; prior finding and parents’ unequivocal denials removed any "reason to believe"; any error would be harmless
