An H. L. Hunt great-grandson took a nine-figure settlement and promised not to contest his father's will, then contested it

H. L. Hunt died in 1974 and left trusts for his heirs. In 2007 his great-grandson Albert G. Hill III sued his two sisters and his father, Albert Hill Jr., alleging misadministration of two trusts of which he was a beneficiary. In May 2010 the case settled with many other suits over the Hill and Hunt estates. Hill III received a nine-figure payment. In return he promised not to contest his father's will, and a federal judge entered that promise as a court order in November 2010. In 2011 Dallas County indicted Hill III for mortgage fraud over a $500,000 loan on a $2.8 million Highland Park house. He said District Attorney Craig Watkins brought the case as a favour to lawyer Lisa Blue, who had represented him and was suing him for fees. On 7 March 2013 Judge Lena Levario dismissed the charges for prosecutorial misconduct and held Watkins in contempt. Hill Jr. died on 2 December 2017. Two versions of his will, both dated 20 December 2014, left Hill III nothing. Hill III argued that the signatures differed and challenged the will in probate court. He lost. The federal court enforced the 2010 order, and in February 2020 the Fifth Circuit upheld a ban on his ever challenging the will. In March 2022 Judge Sam Lindsay dismissed his new suit against the estate as meritless.
