In this mandamus action over an attempt to disqualify counsel, the issue is whether the counsel's prior representation of Thetford, a ward subject to a guardian's appointment, is a conflict in representing the guardian whose appointment Thetford opposed. The lawyer had represented Thetford when she loaned her niece money to buy land and prepared Thetford's will that designated the niece as her "preferred" guardian, then represented the niece in the guardianship proceeding.
