While the legal issue has generated a lot of reactions since it first came out, fans have wondered what the wife to the late singer stands to gain from contesting Lisa Marie's trust.
However, ET recently revealed they seek the expertise of an entertainment Lawyer Mitra Ahouraian, who talked about the legal filing.
According to the lawyer, she thinks the primary reason Priscilla wants to control is to protect the children's interests, as Riley still has two younger siblings aged 14.
The lawyer adds that;
"There is a 35 million dollar life insurance policy that would be to the benefit of the children, and that's a lot of money that can easily go away very quickly if it's not being managed properly."
She also adds that Priscilla doesn't stand to gain financially substantially by serving as the trustee.
