On August 8, the legendary Glen Campbell passed away at the age of 81 from complications relating to Alzheimer's disease, which he had been battling since 2011.

The country crooner, best known for his hit "Rhinestone Cowboy," is survived by his wife, Kim, and his eight children, Debby, who was born to his first wife Diane Kirk; Kelli, Wesley, and Kane, who were from his second marriage to Billie Jean Nunley; Dillon, who was born to his third wife Sarah Barg, as well as Cal, Shannon, and Ashley, whom he shared with Kim.

Shortly after his death, Ashley, the youngest of Glen's children, shared a heartfelt tribute to her father on social media.

"I owe him everything I am, and everything I ever will be. He will be remembered so well and with so much love," she wrote on Twitter.

From an outsider's perspective, the family appeared tight-knit and in-sync, however recent court documents regarding Glen's estate are indicating otherwise.

Apparently, there has been a rift between Glen's family members, and according to the Tennessean, he's left some of them out of his will.

In his 13-page will, which is dated September 1, 2006, he names Kim as executor, and details who his inheritors should be. However, he "specifically excluded" some of his children from directly benefiting from his estate.

Records filed in Nashville's Davidson Probate Court show that Glen's daughter Kelli, and sons William and Wesley, will not be inheriting a single penny from their father's fortune or any related trust.

There is no explanation for why Kelli, William and Wesley have been cut from the will, but some are speculating that it may have to do with Kim, who was previously involved in another court battle with Glen's oldest children.

Back in 2016, Debby and Travis won a legal fight against Kim, who they claimed wouldn't let them visit their father while he was sick.

Ashley later spoke out in defense of her mother through a note on Facebook that read: "My mother Kim has endured unspeakable heartache and has selflessly and lovingly cared for my dad through every step of his disease and continues to do so. She has never denied any of his children a visit, including Debby and Travis who see him regularly yet continue to spread malicious lies about her...They have visitation rights, so what else do they want? One answer: the limelight."

Following their victory, lawmakers passed the Campbell/Falk Act, which allows family members and close friends of a person with Alzheimer's disease, dementia, or other disabilities to visit or maintain close contact with their loved ones, even if it goes against the wishes of their legally appointed decision-maker.

A hearing for the most recent filing is set for January 2018, and this could potentially end up in a another legal battle between Kim and her step-children over the terms of the will.

At the time of his death, Glen had an estimated net worth of 50 million dollars.
