For Child Development Account (CDA) NETS transactions that are above $500 or recurrent CDA GIRO transactions for the CDA member’s sibling, the Approved Institution (AI) must verify and record the relationship between the CDA member and the member’s sibling. The verification may be made, for example, by asking the trustee to declare in writing the relationship between the member and the member’s sibling, or sighting both children’s birth certificates.
