In the terminology of business organizations (Derecho societario), a partner or member’s contributions to partnership or company assets are known as aportaciones, which may include aportaciones dinerarias (“cash contributions”), aportaciones no dinerarias (“non-cash contributions”) or aportaciones en especie (“contributions in kind”), also known as aportaciones in natura. Likewise, aportaciones al capital are “capital contributions,” while the expression aportaciones pendientes often denotes “uncalled share capital.” Aportación has the same meaning in the context of social security law (Derecho de la Seguridad Social): aportaciones sociales (“social security contributions”); aportaciones al plan de pensiones (“pension plan contributions”), etc.
But in the context of procedural law (Derecho procesal) and with respect to the rules of evidence (normas probatorias; normas sobre la prueba), aportación is “production,” as in aportación de prueba (“production of evidence”). Thus, for example, here the expression carga de la aportación refers to a party’s duty to present sufficient evidence in support of a fact or issue asserted at trial. In English this is known as the “burden of production,” and is also often termed “burden of going forward with the evidence.”
