5 Colo. Code Regs. § 1006-1-12
The search shall be conducted by the State Registrar. To maintain confidentiality, the State Registrar shall not divulge the reason for the inquiry to any person except the second birth parent.
Based on information from the birth parent seeking a match as well as information in the State Registrar's sealed file, the State Registrar shall check the following records for a match with the second birth parent:
Efforts to locate the second birth parent will occur within 30 days of the initial match between the adult adoptee and seeking birth parent. The State Registrar will await responses to inquiries for at least 60 days. If the second birth parent has not been located within 90 days of the initial match, the State Registrar shall exchange the current identifying information between the adult adoptee and the seeking birth parent. If the second parent is located, they will be advised of the adoptee's request for identifying information. If the birth parent does not consent, the Department of Public Health and Environment shall not exchange current identifying information between the adult adoptee and the seeking birth parent through the voluntary adoption registry.
Section 12.1 Fees
The birth parent seeking the match shall reimburse the Department the full cost of performing the search, including phone charges and fees.
