What's the story with the Indy IP anyway?

So my (possibly false) understanding is that Ford has the veto power on the Indy character, and that they can't recast him while he's alive? Or am I off base?

Maybe Dial of Destiny's failure has finally nuked the IP but I don't trust Disney not to try and reboot Indy and recast - but is it held back by Ford until he passes? Feels like if they could they absolutely would have shoved Chris Pratt into a reboot but Disney can't.

Just curious in light of the latest podcast and the recent chatter about Back to the Future, which does have some kind of legal veto with the original creator
