If you don’t receive approval, there are options.
In England and Wales, if an agency is planning not to approve the prospective adopters, the applicants can make representations to the agency asking them to review their determination.
Prism Family Law can help you to make representations to the agency asking for any decision to be reviewed.
In England, as an alternative, applicants can request that an independent body (Independent Review Mechanism) undertake this review and make a recommendation to the agency. In Wales, there is the IRM Wales.
