25 CFR 20.510 - How is the court involved in child placements?
The court retains custody of a child in placement and the care and supervision must be given to the appropriate social services agency. While the court can issue any court order consistent with tribal law, the courts do not have the authority to require expenditure of federal funds to pay for specifically prescribed or restrictive services or out-of-home placements of children. Case plans must be reviewed with the appropriate court at least every 6 months and a permanency hearing held within 12 months after a child enters foster care or residential care, or according to established tribal standards. These standards can be established in the tribal code and can be in accordance with available funding source requirements.
