Country singer Glen Campbell 's two oldest children have launched a court fight to take medical and financial decisions away from his wife of 32 years . The move has emerged days after Kim Campbell , whose husband has late-stage Alzheimer 's , was forced to stand in for 78-year-old as he was nominated for Best Song at the Oscars . Now it has been made clear how deeply the singer 's two oldest children , Debby Campbell-Cloyd and Travis Campbell , are unhappy with the arrangement . Scroll down for video . Frail : Country music legend Glen Campbell is now the subject of a court battle between his wife of 32 years and his two eldest children , who say she is isolating him from other family members as he battles Alzheimer 's . The pair filed a court petition in January , saying Kim Campbell is keeping their father 'secluded from the rest of the family ' which has been 'prohibited from participating in his care and/or treatment . ' The petition claims that Kim Campbell is not providing her husband with needed toiletries and clothing , not visiting him regularly and possibly mishandling his finances . It says several of his eight children - the three youngest of which were with Kim - are not on his list of allowed visitors . And it alleges that Kim Campbell has allowed her husband to be interviewed and filmed at the facility , even though his disease has progressed to the point where that is inappropriate . The petition to a Nashville court concludes by asking a judge to appoint conservators and a guardian to protect Glen Campbell 's interests .

Mrs Campbell said : 'It is crushingly sad to see him afflicted with Alzheimer 's but indulging those feelings does not help him . ' I am his wife and no one wants him home more than me but I must do what is in his best interest . ' When questioned by the Associated Press Kim Campbell referred questions about the petition to her attorney , Bill Harbison , who said he could not comment because the judge has placed the petition under seal .

He also starred in a documentary about life with Alzheimer 's , Glen Campbell : I 'll Be Me . Last month , he won a Grammy for his song I 'm Not Gon na Miss You , which plays at the conclusion of the documentary . The song also was nominated for an Oscar .
