It can happen in any family, even famous ones: One sibling ends up administering the family estate and before long, the other siblings feel shut-out, suspicious, or just mad. They ask for information about how the assets are being managed or distributed and don't get answers. Since no one knows how the money's been invested or spent, everyone assumes the worst. Pretty soon, no one is talking to each other, only to attorneys. Then the lawsuits get filed.
A recent AP story reports that two of Martin Luther King's children, Bernice and Martin Luther King Jr. III, have filed a lawsuit against the third, Dexter King, who is the administrator of his father's estate. They claim that he has failed to provide them with essential documents, including financial records and contracts.
If you are serving as a trustee or executor of your parent's estate, or, if you know that you have been named to serve by your parents, but your siblings have not, take note of this classic family feud. Make sure that you understand what your duties are, be careful not to use any estate money for your own use, and, above all, keep really good records of what you've spent and how you've spent it.
When your siblings ask you for accounting information, provide it. In this case, silence is not golden.
