London, July 30 Lawyers representing Michael Jackson's mother Katherine have come under fire over claims that they are trying to "rewrite" the pop superstar's will against his dying wishes.

Michael had appointed attorney John Branco and business associate John McClain to take charge of his affairs in a will signed in 2002.

However, according to reports, Katherine is trying to get involved in all decisions regarding her son's estate. In fact, she has mounted a legal battle to ensure she is consulted on all issues.

Londell McMillan, Katherine's lawyer, has insisted that the 79-year-old is not looking to contest the singer's will.

In a statement released earlier, McMillan said, "Despite false reports, neither Mrs. Jackson nor any of her lawyers has or will be contesting the will. Nor has she decided whether or not to raise any challenge to the appointment of the executors named in the will or whether to seek the appointment of an additional co-executor. Her top priority remains the care of her son's three children."

Recently, McMillan claimed Branco and McClain were making unjustified confidentiality demands from Katherine in exchange for access to Jackson's contract with concert promoters AEG, who were in charge of his ill-fated London comeback shows.

The co-executors, however, have rubbished the claims, insisting that they simply asked the Jackson family matriarch to agree to keep the details of the AEG deal secret from the media - a request her lawyers denied.

Also, Branco and McClain are convinced it's just another attempt by McMillan to have Katherine put in charge of the estate, reports The Daily Express.

A representative for the co-executors states, "(Katherine's lawyers want to) rewrite Michael's will to make Mrs. Jackson 'Guardian of the Estate' and have her appointed as an executor." (ANI)
