I am learning about estates, wills, and probate courts. I am wondering about the following situation and procedures that may follow:
Beneficiary 1 (or B1), the sole beneficiary stated on a will, was awarded an entire estate after the benefactor's death. B1 has a good relationship with their two siblings. B1 and the two siblings all had a mutual understanding that the estate should be divided into thirds and distributed accordingly. It was also the benefactor's intention to do so, but not explicitly stated in the will. The assets in the estate are solely investment accounts and no real estate property.
What could the three individuals consider to split the estate up in this fashion?
Any information to learn about this subject would be appreciated!
