Recommended Practice based on International Guidelines
For births that occur outside a health facility, the most effective approach is to designate the birth attendant - e.g., doctor, nurse, or midwife - as the informant. For births occurring outside a health facility without a birth attendant, an effective approach is to designate community health workers (including vaccination workers, nurses, doctors and other health professionals who see newborns for paediatric visits) as informants to register the birth of children that are unregistered and visited by them. Alternatively, some countries follow a two-step process, wherein the healthcare workers notify the birth to the civil registrar; however, the parent or other informant must still declare the birth to the civil registrar in order to register the birth.

Legal Analysis
For births that occur outside health facilities but under medical supervision, Article 49 of Decree 1260 of 1970 states that the certificate from the doctor or nurse that assisted in the mother during labor, will be used as confirmation of the birth by civil status register the official. In the absence of a certificate, the birth will be confirmed by an affidavit of two competent witnesses.
