This appears in a document relating to powers of attorney in a business for translation from Spanish into UK English.

Context:

1. DISPONIBILIDAD DE BIENES Y VALORES
Los apoderados podrán:
- *** Realizar todos los actos y contratos *** sobre títulos valores, acciones, participaciones, obligaciones o cualquier otro derecho incorporado a un título que impliquen facultades de propiedad del título, en particular (v) firmar pactos de socios o accionistas que vinculen la posición de la Sociedad como accionista, socio o partícipe en la entidad de que se trate,
- Las facultades anteriormente indicadas incluyen, en cada caso, la de modificar los actos o contratos celebrados en uso de las mismas, incluyendo la novación subjetiva y cesión del contrato.

I would normally translate this as 'to perform all acts and enter into all contract' or something similar but I have been given a supporting document as a guide which I have been told to stick to strictly and every time this phrase comes up - and it comes up a lot - it has been translated as 'Execute any legal provisions and contracts'. The supporting document is a very good translation so I have now come to doubt my own opinion. Obviously an 'act' can be a 'legal provision' in some circumstances but here I think it is completely wrong. Do let me know your thoughts. TIA.
