Every month for more than 20 years, Helen Vickery paid her three lawyers 45 percent of an annuity payment she was awarded in litigation related to her contentious divorce from Baytown lawyer Glenn Vickery.

But Helen Vickery died in 2017. Now, her daughter wants a judge to decide whether her estate must continue to pay the three Houston-area lawyers, and whether the $6.5 million in monthly payments that her mother already paid to Ronald Krist, Richard Morrison and Roy Mease from 1995 through 2017 were ever valid.
