I don't believe it. No effing way were they getting 80k an epic for Counting On. iirc it came out during their divorce that J&K plus 8 were getting around 20k per ep at the height of their fame/popularity. That's what i expect the Duggars were getting for CO.
I'm surprised he hasn't violated the terms of his release yet since, y'know, rules don't apply to Duggars. But another six to eight months of being babysat greatly increases the odds of him violating the terms.
There's no legal requirement for spousal consent for a vasectomy or tubal ligation. However private practices can have their own policies. That being said, Josh could always sneak off to *gasp* Planned Parenthood. I doubt they have a spousal consent policy.
