You should get the Apostille first and the translation done afterwards. The translation then includes the document itself as well as the Apostille attached to it.

I've done the Apostille in two other countries but sadly not in the UK, so I'm not sure who the issuing authority is. It's usually just a case of booking an appointment and bringing whatever document you need the Apostille for. Then it will either be done on the spot or available for collection at a later time (or date).

It really is the simplest of things so if you do opt for some entity doing it for you then see how much they charge compared to doing it on your own. In some countries a notary for instance can arrange the Apostille for you... but they can charge a ridiculous fee like 10x as much for what is really something straightforward (fill in form, present doc, pay, collect doc with Apostille attached).

yes agreed …. I phrased that incorrectly (now I’ve reread it)

FCDO actually do them in the UK, there is an e-apostille that can be done online but I don’t know whether Spain accepts this for a death certificate. The standard public service can take 15 days to complete by post, there are various fast track services that FCDO offer but I’m pretty sure these are only available to registered businesses, hence my suggestion of engaging a specialist company particularly if time is an issue. When I researched this albeit quite a while ago for the death certificate some translators charged almost as much as getting both done together, then of course there is the added time of getting the translation done (15 days Apostille + translation time) . I’ve had various documents and certificates apostilled and translated over the years for visas etc and have always used a professional company to do them but that’s just me. 😁
