Justice A. Kirke Bartley estimates it may take two months for the trial of Marshall, who's 84, and 66-year-old co-defendant Francis Morrissey. The judge has said he must first find out who can serve on a jury that long.
Morrissey, who's a lawyer, is accused of altering Astor's will so that Marshall would get money meant for charities.
Astor died in August 2007 at age 105.
