Getting into Partnership with Spanish Partner for non Resident

My advice with a bad experience in this respect, is to stay away from it. There are all sorts of risks, and they are not only losing your investment. The other partner, unless you trust them with your life, can fob off all expenses to your account, including tax obligations, make it appear as if you spent all the capital and even claim from you at the end. Most people are friendly and honest in Spain, but with increasing hunger and economic decay, comes depravity of Spirit. I would not recommend doing business with someone you barely know from a country where people are short of cash. That said, it is possible and legal, and if you trust the person, go for it. Start small and grow it incrementally. Also the fraud may only be apparent 2 years down the line.
