Two surviving sons and surviving daughter of Martin Luther King are unable to agree on the handling of the estate and may go to trial, according to a Fox News article "Family feud over Martin Luther King's Bible, Nobel Prize moves closer to trial." A trial has not been scheduled yet, but it could come as early as August.
King's heirs are currently the only shareholders and directors of the corporation that oversees King's estate and are in a dispute that began in 2014 when the two brothers voted to sell their father's Nobel Peace Prize and personal Bible to a private buyer. Their sister voted against the proposal and refused to turn the items over claiming they were not part of the estate. The prized possessions are now in a safety deposit box pending the outcome of the legal dispute between the relatives.
The case was previously headed to trial in 2015, but the parties informed the court they were close to a settlement and asked to go to mediation. It now appears the mediation failed to result in an agreement, so the case is expected to go to trial in the near future.
The parties could still agree to a settlement. However, the mediator they used to resolve their conflict was former President Jimmy Carter. If he could not facilitate an agreement between the siblings, it is doubtful that one will be reached now.
