I don't know for sure about all the legal documentation, but I wouldn't be surprised if they've arranged something. That's been covered for Superman, for example, unless I'm mistaken? I think I'm remembering Lionel helping out on Smallville. (In Byrne's reboot, he came to Earth during a long winter so the Kent's just pretended he was their son; there have been other stories.)
