1. 1968? 43 years before her death? Those relatives were not important to Ms. Clark. Nor was she to them.
2. The grounds for challenging a will are either lack of mental capacity or undue influence. If she was not competent to execute the second will, it is doubtful she was competent the prior month to leave everything to the relatives.
3. The lawyer drafting a will should never be a beneficiary of the will. He should bring in another attorney to prevent the appearance of undue influence by him.
4. My guess (which based on my prior snark and other poor predictions in this blog is probably wrong) is that she reflexively signed a will leaving her assets to her relatives even though she had not seen them since the RFK and MLK assassinations and the moon landing, then reconsidered and decided to leave her assets to people who had made a difference in her life.
5. More bloggers, and journalists, should admit their poor prognostication abilities.
