Drafting a fair will?

Business Insider is a site I read often.  Recently, it had a short article on drafting a fair will. Of course, "fair" is in the eye of beholder and heirs often have differing ideas of what is fair.  However, I agree with the general point of the article, which is that leaving materially unequal distributions is likely to lead to family conflict.  I particularly agree with this point:

 "For children, a disinheritance can leave a psychic wound they may never recover from, leading to an all-out war."

In my experience as a probate litigation attorney, substantially unequal distributions are often the result of one child taking advantage of a parent's failing physical and/or mental condition to execute a will that favors that child.  That understandably leads to bitterness and often a will contest.
