Three of Glen Campbell's adult children who are seeking to challenge a will that cuts them out of inheriting any money from his estate are asking a judge for a delay in filing their legal challenge, claiming the timetable that has been set for them is impossible to meet.

Travis, Kelli and Wesley Campbell are Campbell's children with his second wife, Billie Jean Nunley, and they are contesting the validity of a will Campbell's widow, Kimberly, filed that excluded them from inheriting after Campbell died.

Nashville Probate Judge David "Randy" Kennedy recently ruled that they have the standing to dispute the will, and Kim Campbell agreed not to challenge their right to challenge. According to Nashville's Tennessean newspaper, Judge Kennedy gave Campbell's children only three days to file a formal complaint that details the basis for their challenge in a new ruling last week. Their lawyer, Christopher Fowler, says he and his clients "believed in good faith" that the deadline has been placed on hold pending a motion for a status conference scheduled for Sept. 14.

Fowler's new four-page filing asks the court to allow "a minimum time" for him to file a formal complaint on behalf of his clients, and also reiterates his previous argument that Tennessee state law does not require someone who's contesting a will to even file a formal complaint.

It's the latest in a series of legal skirmishes between the two warring parties since Campbell died on Aug. 8, 2017, after a long battle with Alzheimer's. The disinherited children are questioning his capacity to sign the document and charging that he was under undue influence at the time. There have also been questions regarding Campbell's former business manager, Stanley B. Schneider.

Another of Campbell's daughters, Debbie Campbell-Cloyd, has alleged that royalties Campbell's music has earned since his death have been deposited into a joint account the singer held with his wife, over which Schneider has power of attorney, instead of an account that is controlled by the estate. Judge Kennedy recently ordered Schneider to reconcile the account and list all of the transactions since Campbell's death. Schneider has also been subpoenaed to provide legal and financial documents that span decades, including some that provide details about Campbell's ownership stake in the Arizona Diamondbacks.
