I am British and keen to opt out of the scheme, as it's unlikely I will retire in Colombia. Does anyone know if this is possible and whether I need to present a statement re my UK pension to my employer or Colombian pension authorities? I have been on the internet to try and find out whether the office is for the state pension system so I can go there in person and ask?? If anyone has any experience of opting out. My language institute told me I couldn't but I suspect that they don't really know the law that well.
