A former candidate for the Hall County probate judge “has been exonerated of any wrongdoing” in a State Bar of Georgia complaint stemming from a Douglas County dispute over a woman’s 2010 will she helped draw up, said a lawyer involved in the dispute. Brook Davidson, who works in Gwinnett County Probate Court, had been accused by two siblings — children of Joyce Plybon, the woman Davidson represented — of writing the will to directly benefit their sister, Mary Marvel, also a former client of Davidson’s. Plybon, who died in April 2011, had a will made in 1990 that sought to divide her estate equally between all three of her children.
