Case law for what? If you want caselaw that says that the custodial parent can claim the child on their tax return even if there is a court order requiring something different, you don’t need caselaw for that, that is the plain language of the federal tax statute.
If you want caselaw for the proposition that the family court should revise a custody order if the non-custodial parent is not following their responsibilities, you would be looking for court cases decided in your state, because every state law is different.
