Naomi Judd's will is being challenged after a handwriting expert noticed a notable variation in her signature.

The famous handwriting expert spoke with Radar Online about the country singer's last will and testament, which is presently laying the groundwork for a nasty struggle over her $25 million wealth.

These surprising revelations come as her daughter Wynonna Judd is apparently consulting with attorneys about contesting her mother's will, which gave her spouse of 33 years, Larry Strickland, complete control of her wealth.

Peggy Walla of LPR Investigations believes Wynonna's accusations will stand up in court after discovering six flaws in the five-page document, which was filed in a Williamson County Tennessee Probate Court in May, a month after Naomi Judd's unexpected death.

"The initials and signature are traced - she does not write them," she informed the outlet after analyzing the document, which was executed in front of two witnesses in November 2017.

Peggy went on to explain that the signatures were faked.

"That suggests someone traced her customary signature on a lighter piece of paper," the private investigator explained.

"There is no flexibility. When you sign your name, the pen is already in motion when it hits the paper, giving it a feathery effect where there are intentional 'starts and stops.'"

Peggy said that the top of the "O" in Naomi appears to be chopped off, and she feels there is no reason for it to be cut off in this manner.

She also noted the initials at the bottom right of the three pages of the paper, with the "J" crossbar ends pointing up, but the singer's handwriting has the "J" crossbar end sloping down.

"The (pen) pressure is the same all the way through - the beginning and stopping points of the initials are blunt rather than feathery - as if someone started and stopped on purpose."

Peggy also stated that the original will should be forensically analyzed and that Wynonna might challenge it in court as a probable forgery.

Naomi Judd, 76, committed herself on April 30 after a long and difficult fight with mental illness.

Her husband was named executor of her estate in her will, but her daughters Wynonna and Ashley Judd were not.

While Wynonna is apparently going to contest the will, her sister is supporting Naomi and Larry in their choice to leave him everything.

According to an informant, the 58-year-old, the other half of The Judds, believes Ashley and Larry "conspired against her."

However, the 54-year-old actress understood what her mother was doing by not dumping a large sum of money on her elder sister's lap.

This is because Wynonna allegedly struggled with money throughout her life, spending every penny she earned while recording songs and performing.

She even checked herself into a money disorder treatment clinic in 2004.
