Riley Keough, daughter of Lisa Marie Presley, to become the sole trustee of her late mother's estate

A dispute over the authenticity of Lisa Marie's will was resolved through an undisclosed agreement

Keough filed a petition in court to seek approval for the settlement, granting her control over the estate

The estate includes proceeds from a life insurance policy and Elvis' iconic Graceland mansion

Priscilla Presley, Lisa Marie's mother, will receive a lump sum instead of being a co-trustee

The settlement saves legal fees and honors Lisa Marie's wishes while protecting the family's best interests

Keough will fulfill the role without charging a trustee fee, ensuring efficient management of the estate

The settlement brings closure and privacy to the family as they mourn and move forward together
