Under Resolution No. 616 of December 29, 2004, the parents or legal guardian are designated as the primary informants for birth registration. In their absence, relatives up to the third degree of kinship may submit the registration application, and if no relatives are available, municipal, ecclesiastical, administrative, or judicial authorities may do so. The Resolution does not distinguish between births occurring inside or outside health facilities, nor does it assign a specific role to health personnel in the registration process.
The law does not clearly designate a single primary informant for deaths occurring in health facilities, as recommended by international guidelines. However, Article 48 of Supreme Decree No. 24247 of March 7, 1999, establishes that the Civil Registry Officer records the death upon presentation of the medical certificate attesting to the death, which implies that the physician is the person providing the information when the death occurs within a health facility. In places where no physician is available, the article states that the Civil Registry Officer must verify the death.
