Dead three, SyFy award wining or nominated short story I did read in Latvian translation (but reasonably sure the original language was English) sometime during last decade of previous century in a collection, so the story might be older, possibly significantly.
It might have title roughly "Mr. [Smith*], do you exist?" however, I have forgotten the exact name used in it, and it was translated anyway, so might differ. I haven't memorized the author either.
Synopsis as I remember it:
A driver of extreme car racing has suffered so many injuries over the years the only part of his original body left is one hemisphere of his brain, and it is giving up, producing insufferable headaches and other glitches. The solution is obvious, the prosthetics company he has a lasting relationship with is keen to replace it too.
The migration is apparently seamless as he had his other half brain electronic for years, and his health problems are solved in radical way, he is completely mechanical now. Unfortunately, his racing association has problem with it, they say he's not a human anymore and thus can't compete. Additionally, when he goes to beach he discovers he's tattooed with "Made by [MegaCorp*]" advertisements.
Thing is, the insane amount of technology he's packaged with is still cutting edge and installed on credit, and is of a book value he has no hope to ever repay, especially since he now lost his source of income. Actually, he's under acute threat to be disassembled for recovery of parts.
That's the situation the story takes to courtroom (but I have forgotten who takes whom to court over what exactly) where the problem quickly boils down to the question, who or what, and if at all he now is, in need to establish his personhood in the first place.
I do not remember how it was resolved.
[*] placeholders, not usable for search.
I may think I know in which shelf and roughly where the book might be, but may be mistaken and not planning on visiting that city anytime soon. Even so, I'm searching for a reference rather than read, and even as such, would be interested in original (or English translation) as well.
