May 17 (UPI) -- Alan Thicke's sons Robin and Brennan Thicke have taken his widow Tanya Callau to court over claims that the prenuptial agreement she signed in 2005 before marrying the actor is invalid.
In a petition filed Tuesday in Los Angeles County Superior Court, Alan and Brennan claim that Callau is seeking to receive more of Alan's estate in the wake of his death in December, People magazine reported.
Upon his death, Alan left each of his sons in equal shares "ownership of the Carpinteria, California ranch that he bought in 1989 and desired to keep in his family forever, 75 percent of his personal effects and 60 percent of his remaining estate," the petition states.
Callau obtained "all of the ranch's furnishings, 25 percent of his personal effects, a $500,000 life insurance policy, all of his death benefits from pensions and union memberships ... and 40 percent share of his remaining estate. Alan also provided that Tanya may live in the Ranch after his death so long as she maintains the property and expenses," it continues.
"Now that Alan is dead, Tanya claims there are numerous problems with the Trust and the Prenuptial Agreement," writes Robin and Rennan's attorney Alex Weingarten in the petition.
"Tanya asserts that there is no chance the 'Prenup' could withstand legal challenge and that she has very significant community rights in the Trust's assets and rights of reimbursement with respect to improvements to the Ranch. Tanya also claims 'Marvin rights' asserting that she had to forego opportunities to pursue and advance her own career in order to support Alan and be his companion and partner, including raising Carter," Weingarten continues.
The sons also say that Callau has threatened to go to the tabloids if her demands are not met. In response, Callau's attorney Adam Streisand stated that the 41-year-old is still "grieving the death of her beloved husband and out of respect for Alan's memory intends to handle his sons' false statements privately."
Alan and Brennan "made every effort to resolve this without the need for going to court" and filed the petition to "honor the memory of their father, protect his legacy, and prevent his testamentary intentions from being undermined by avarice and overreaching of his third wife, Tanya Callau," Weingarten said to The Hollywood Reporter.
Alan died at the age of 69 while he was playing hockey with 19-year-old son Carter at a Burbank ice rink.
