A will contest is usually a legal challenge of a decedent's last will and testament by an heir of the decedent who is not happy with the will which has been filed with the probate court. Most likely because the heir has been left out of the will or received a lesser portion of the estate than the other heirs.
Well, they were certainly both mega-stars and monster musical legends. But there is more. They were both mega millionaires but neither one of them did any estate planning, nothing. Neither Prince nor Aretha had a will or a trust. They both passed away leaving their massive estates to be decided by feuding relatives who will be tied up in courts for years to come. This is just astonishing. Even more so because my understanding is that they both keep tight reins on their business arrangements and finances. How did they let this happen? I suspect we will never know.
