From the Indiana Law Blog comes this will drafting legal malpractice case, in which the drafting of a will caused adverse tax consequences.  Plaintiffs sued, and attorney’s successfully moved for summary judgment, only to lose at the appellate level:

"The trial court denied the Lawyers’ motion as to one issue, but granted it as to the other. The Carlsons now appeal, raising a single issue, which we restate as whether the trial court properly granted summary judgment based on its determination that reformations to the Wills drafted by the Lawyers effectively eliminated any malpractice that occurred relating to the drafting of the original Wills. On cross-appeal, the Lawyers raise a single issue, which we restate as whether the trial court properly denied its motion for summary judgment on the grounds that the original Wills would result in adverse tax consequences. The Lawyers also raise the following issues: 1) whether the “substantial adverse interest exception” protects the Carlsons from adverse tax consequences; 2) whether the Carlsons have brought this suit too early, as the IRS has not yet assigned a tax penalty; and 3) whether the trial court improperly considered the opinion of an attorney hired by the Carlsons. We conclude the adverse interest exception does not protect the Carlsons, the Carlsons are not precluded from bringing their suit at this time, and that the Lawyers waived their argument relating to the opinion of the expert witness by not raising it before the trial court. We further conclude that the trial court properly found that the original Wills would result in adverse tax consequences, and affirm the trial court’s denial of the Lawyers’ motion for summary judgment on that issue. However, we conclude that the reformations did not effectively avoid potential adverse tax consequences, reverse the trial court’s grant of summary judgment on that issue, and remand for further proceedings."
