The Michael Jackson Estate just got the ok from a judge to sell the Hayvenhurst mansion which Michael and the rest of the family called home for decades, and buy another home for Katherine and MJs kids.

But here's the thing. We've learned the Estate doesn't want to sell Hayvenhurst -- at least for now, because it's being extensively renovated. But the Estate now has the green light to proceed whenever it chooses.

And the judge made another order -- allowing the executors to put $30 million in the Jackson Family Trust for the benefit of Katherine, Michael's kids, and his charities.
