Argentinian citizens with a DNI number can request a digital copy of a birth/death/marriage record that took place in the city of Buenos Aires through this site - https://www.buenosaires.gob.ar/tramites/solicitud-de-partidas. One needs to know the exact spelling of the last name, otherwise they will not find it. It costs 650 Pesos (about 7 USD).
