Mickey Rooney’s Body Won't Rest In Peace -- Battle Rages On Over His Will

The battle for Mickey Rooney’s will is set for a heated court war, as his wife Jan is officially contesting it next Monday, RadarOnline.com has exclusively learned.

Jan's team of lawyers will claim that the will is invalid under California law as Mickey was under "undue influence" and "lacked capacity."

The will stated that Rooney had an estate worth $18,000, which was to go to his stepson Mark Aber and his wife, who were his caretakers at the time of his death.

Jan, her son Chris Aber and eight surviving children were all cut out of the will even though Jan and Rooney were married for 36 years and Chris had looked after Mickey for over three decades. They claim that a will he made out 11 years ago is still valid, which would make Jan the sole heir to his fortune.

A court hearing is now set to take place on May 12 at 8:30 a.m., according to documents obtained by RadarOnline.com.

EXCLUSIVE DOCUMENTS: Petition For Probate Of Mickey Rooney's Estate

The Hollywood legend’s attorney and conservator Michael Augustine filed a petition for probate to the Los Angeles Superior Court, and it requests that he "be appointed as personal representative to administer the estate of the decedent. The petition requests the decedent's Will and codicils, if any, be admitted to probate."

The petition goes onto say, "If you object to the granting of the petition, you should appear at the hearing and state your objections or file written objections with the court before the hearing. Your appearance may be in person or by your attorney."

According to a family source, Jan is very confident that she will get the will null and voided. The same insider also said that son Chris will be seeking monies owed to him, as a creditor of Rooney. He’s claiming that he’s owed up to $75,000 from Rooney on unpaid hotel and restaurant bills he shelled out during touring in the last decade.

"The lawyers have called the latest will ‘theatrical’, in their words, and said that it has no credibility. They reckon that it doesn’t stand up to Californian Law, as Mickey was 93 years old when he signed the document and under conservatorship," the insider told RadarOnline.com.

"They think it should be dismissed. They’re painting a picture of a couple still very much in love. Mickey never officially separated from Jan – it was only because she chose to live with Chris and Mickey with Mark that this whole row started in the first place."

The source continued, "The ace up their sleeve is that they’re going to expose just how much of Mickey’s millions has gone on lawyers fees and the same people who are meant to be protecting him now.

Ordinarily, anyone contesting a will, after receiving notice of the petition to administer the estate, must bring their objections at, or before the date, of the hearing on the petition to administer the estate. In California, this is usually 30 days.

DOCUMENTS: Mickey Rooney's Trust

By the time of his death at 93, the actor's estate had been reduced to $18,000, which he blamed on elder abuse and financial mismanagement by stepson Chris.

The will was signed by Rooney on March 11, 2014, and filed to the Los Angeles Superior Court on April 8, 2014.

Just over a decade earlier, on January 15, 2003, Jan and Rooney signed over all their assets to 'The Rooney Trust' in a legally binding contract, which included all of Rooney and Jan’s assets.
