A Juvenile Court Judge just made a “true” finding that I molested one of my children. Can this finding be used against me in my criminal trial?

No. A Judge’s finding in a dependency case cannot be used against you in your adult criminal trial. The burden of proof in the Juvenile case is a preponderance of the evidence, which is a much lower burden of proof than a criminal case, where the burden of proof is beyond a reasonable doubt. The Juvenile Court’s finding is irrelevant to the criminal case.
