Check the listing yourself — before you ever contact the seller.
You found a business for sale in Spain or Portugal. Before you write to anyone, there are checks you can run yourself, today, in about twenty minutes — the same first moves a professional makes.
Answer a few questions about the listing and this page assembles them into a plan, in order, with the public sources to run them in. This tool will never tell you a listing is genuine, and it will never tell you a listing is a scam. No page honestly can — and any page that does is selling you confidence. What it gives you instead is the set of questions the listing has to survive, and what each answer does and does not mean.
This is a free, automated informational tool. It does not create a professional relationship, it is not due diligence, it is not advice on this transaction, and it is not a review or an assessment of any seller, listing or business. Its output is built only from what you type; nothing you type is a fact about anyone. This page checks nothing itself — it shows you where to look.
Fastest free start: paste the listing link on the homepage — your first pack builds itself in a minute.
