Conn. Gen. Stat. § 46b-116j
Where any parent or Indian custodian voluntarily consents to a foster care placement of an Indian child or to termination of parental rights, such consent shall not be valid unless executed in writing and recorded before a judge of a court of competent jurisdiction and accompanied by the presiding judge's certificate that the terms and consequences of the consent were fully explained in detail and were fully understood by the parent or Indian custodian. The court shall also certify that either the parent or Indian custodian fully understood the explanation in English or that it was interpreted into a language that the parent or Indian custodian understood. Any consent given prior to, or within ten days after, birth of the Indian child shall not be valid.
