According to the suit, Constance refused to have a job, so the money was supposed to be to help Constance provide for Leighton’s younger brother Lex, who has severe medical problems. Leighton was supposedly sending $7500 a month to help out.

Also according to the suit, Constance is alleging that she and Leighton had a contract wherein Leighton was required to give Constance $10,000 a month for life. Constance is allegedly threatening a $3 million lawsuit against Leighton. Leighton wants a judge to declare there is no such contract, which Leighton maintains is a complete fabrication by her mother.
