Multiple wives, the last being a full generation younger. Multiple kids, with different mothers. Multiple wills. An end-of-life battle with Alzheimer’s disease.

Although such factors concurrently on display regarding one individual’s estate planning do not automatically portend down-the-road legal troubles, they certainly do up the odds.

And in famed entertainer Glen Campbell’s case, that combination of family-centric influences unquestionably played a major role in material developments that have now emerged in center-stage fashion in a burgeoning estate spat.

Campbell died a year ago yesterday. It turns out that, although the multi-talented artist had eight children, three of them were denied any inheritance rights.

Unsurprisingly, they have a problem with that, recently petitioning a Tennessee court for certification that a valid will contest exists.

The court agreed, noting late last month that the children have a legal right to contest two wills that were executed years ago. Reportedly, the judge presiding over the matter was influenced by Campbell’s mental state during his latter years of life. The children argued that Alzheimer’-linked impairment rendered him susceptible to undue influence.

The more recent of the two wills in question, executed in 2006, named Campbell’s last wife and current widow Kimberly as estate executor. That document lists her and Campbell’s five other children as beneficiaries. Kimberly Campbell was aware of the left-out children’s intent to contest the will, and gave notice that she would not challenge their petition.

Issues relevant to the prior wills are not the only matters of concern regarding the late entertainer’s estate. Additional questions are aimed at one of Campbell’s ex-managers, specifically targeting actions he has taken in his capacity as a temporary estate administrator.
