From a brief google it seems like the son MAY have (mild) learning disability and could maybe be considered vulnerable, I can only guess that's what's being implied, OR again it could be that he's due to inherit money and there's a concern of him being exploited financially and his dad wants to put something in place that means he doesn't get $$$ if she's involved in his life. All just speculation obviously, but speculation is fun so why not.

She was (quite blatantly) getting quite a bit of cash from Jade at the height of her fame.
