I cannot understand the post, either, but not because of the language (it IS English), but because of its logic or rather the absence thereof.
Nobody can do a PhD with a thesis "basically written", that's nonsense. Nobody cares if "said relative" holds an MBA, as these things don't count. Every PhD students starts on the same level, as a student, and with all respective responsibilities. If said relative wants to do a Ph.D, said relative should think about going on this forum himself.
