Lisa Marie Presley‘s lawyer has revealed the real reason behind her divorce from Michael Lockwood.

“He apparently was in charge of her assets throughout the marriage and didn’t do what he should have done on a fiduciary basis. He took advantage of her,” Lisa Marie’s legal rep Ronald Litz told People.

Litz additionally confessed Lisa Marie’s split from Michael, 55, was caused by his parenting skills. The couple — who married in January 2006 — are parents to seven-year-old twin daughters Finley and Harper.

“There are some problems with [Michael] being a good father, in terms of what a father is supposed to do,” Litz said, adding Lisa Marie, 48, is seeking full custody of their daughters in the divorce.

“They’re not trying to work it out and get back together. She’s done,” Litz continued. “It’s tough on her, but she’s going to get through it. There’s so much stress and nonsense that goes on during divorce. But she’ll be fine ultimately.”

This is Elvis Presley‘s daughter’s fourth failed marriage. Lisa Marie was previously hitched to Danny Keough — with whom she has a 27-year-old daughter, Riley, and a 23-year-old son, Benjamin — from 1988 to 1994, to Michael Jackson from 1994 until 1996 and to Nicolas Cage from 2002 to 2004.
