O.J. Simpson left a last will and testament when he died of prostate cancer on April 10, but a new allegation claims his signature on the $15 million document is forged.

According to sources, the families of O.J.'s ex-ladylove Nicole Brown Simpson and her dead waiter companion Ron Goldman have the option of contesting the will in probate court, perhaps collecting a long-overdue judgment for his role in the pair's horrible deaths.

It has been reported that O.J. Simpson's undisclosed income from cash transactions in the memorabilia industry, other assets, and his NFL pension could total up to $15 million, which was hidden in a trust.

However, a shaky signature might allow the Goldmans and Browns to contest the will, which was signed about four months before the 76-year-old NFL veteran died in Las Vegas and left his fortune in a trust for his four adult children.

Tipsters said that if the document is verified by a judge, the bereaved families' cash grab might be permanently halted. O.J. Norman Pardo, Simpson's longtime manager, says it is highly possible that the disgraced running back either did not have a will or could not be located.

Norman reportedly believes that a paper could have been hastily drafted and signed after his death to prevent the Goldmans and other creditors from claiming any assets O.J. had.

While there is no proof to back Norman's conspiracy allegation, renowned forensic handwriting expert Peggy Walla told Globe Magazine that she immediately noticed two big flaws in O.J. Simpson's signature, as well as six other unusual flaws.

She decided that it is quite likely that O.J. didn't sign his handle. "It only takes one significant, unexplainable difference to rule it a forgery," Peggy of LPR Investigations stated.

Notably, the signature lacks the once-heralded running back's trademark J, which Peggy views a red flag. "Missing the middle initial J-knowing that he went by 'O.J.' for God knows how long-I think is very significant," she said, noting that O.J. always included the letter while signing his full name as Orenthal J. Simpson.

Peggy also examined a copy of the will under a microscope to compare it to O.J.'s distinctive handwriting features found on certified autographs, such as where pen strokes begin, finish, and/or move along the signature line, as well as the amount of pressure applied to the paper.

"The signature on the will is also missing the individual characteristics present in all of his autographs. All off us start and stop our letter Os at the same spot, which is unique to the signer. That's how you know when it's a forgery-when it starts and stops in a different spot. In the will, the beginning of the letter O is on the inside of the O. Every other O that O.J. made started on the outside," Peggy stated.

Peggy also focused on the letter S, which did not match O.J. Simpson's recognized style and pen stroke failed to fluidly transition into the next letter.

"If you look at all the other autographs, all his Ss are in the shape of a figure eight-and the S on the will is NOT! NONE of his signatures are like that. The S is wrong! The O is wrong!" Peggy stated.

She also performed considerable research on the handwriting of patients with terminal illnesses and convinced Globe Magazine that even if O.J. Simpson's calligraphy would remain distinct even if he was under the influence of a potent mixture of prescription drugs-or was temporarily rendered unconscious.

"His handwriting doesn't look like that of a terminally ill patient," Peggy added.

Malcolm LaVergne, O.J. Simpson's longtime lawyer, claimed the NFL star was on his couch "drinking beer and watching TV" just two weeks before succumbing to the disease, as per CBS News. His will named Malcolm as the estate's administrator and was attested by real estate agent Robert W. Zerkel and Connor Kersten, a paralegal at Cassady Law Offices, which filed the document in Clark County's probate court in Nevada.

Meanwhile, Norman reported that his eyes bulged when he viewed the will. "I've seen O.J. sign thousands and thousands of autographs, and I immediately knew it wasn't his signature. That signature wasn't even close," he confided.

O.J. Simpson's camp has yet to comment on the claims that the late NFL legend's $15 million will is fake. So, fans should take all these speculations with a pinch of salt until everything is proven true and correct.
