That's only relevant to marriages. Unless it's on his birth certificate, it's not his name. Nor has he ever said that was his name. I'm sure at some point in Spider-Man history, he's had to put his full legal name and he put Peter Benjamin Parker. I know on my birth certificate and my brother, sister, and cousins their full names don't include any more than 3 names outside of first, middle, and last.
