I've been doing some research (from a US perspective) on this topic. From what I've read, a single-person corporation only shields you from things like not being able to pay back a business loan, or paying suppliers, etc. But it doesn't necessarily shield your personal assets from liability lawsuits, since the person who is responsible for the potentially liable action is the same as the company, and is the same as 100% of the shareholders. To get that protection, your best bet is to have a good umbrella insurance policy, along with having a lawyer draft appropriate terms and conditions for your services (such as "this software is not guaranteed to be fit for any purpose, and should not be used for any purpose", but worded a bit different).

> i'm not a lawyer, and this is not legal advice, i know nothing of eu laws either

Why do you feel the need to comment then?

> i would strongly suggest getting a lawyer to handle this.

As stated above, I couldn't find one, someone who can deal with tech-y stuffs here in my area.

why do you need a tech-y lawyer? I'd look for a fiscal advisor, because this is mostly about getting your tax liabilities right. And they should know enough about forming companies.
