They can still get that done, just not in the house. They may decide to go to a hospital or something for that.
I don't blame them for doing this, after all the stuff that's gone on in the past few days, I don't trust any of those involved in the mess. I also think Janet is hurting her reputation by aligning with her shady ass brothers. Randy and Jermain have kids with the same trashbox, and they expect MJ estate to pay their bills? How does that make since. If they are truly concerned about their mothers health, then ask her to step down 100%. They will NEVER do that, because they need those monthly checks she's bringing in.
MJ apparently told them he would redo his will because of their support during his pedo trials, but I think he lied to them. If this will is thrown out, the one before is similar, and also cuts them out 100%, so they should just move on and get fucking jobs/tour state fairs, or do whatever it takes to make a living.
