Shannen Doherty's estate has accused her ex-husband of failing to follow through on their divorce settlement.

The late actress filed for divorce from Kurt Iswarienko in 2023 after 11 years of marriage and signed the settlement one day before she died in July 2024 but attorneys for her estate have now filed a petition against Iswarienko, claiming he has not abided by the terms of the legal agreement.

In a new filing obtained by PEOPLE, Shannon's legal team and Christopher Cortazzo, trustee of the Shannen Doherty Family Trust, alleged that her ex-husband failed to comply with several "monetary obligations" from the divorce settlement.

He was required to sell her $1.5 million Texas home and "equally divide the net proceeds with [her] estate" but, according to the filing, he has "refused to list" the home, where he appears to be currently living.

He allegedly has also "refused to return [Doherty's] items of personal property".

Additionally, Iswarienko has reportedly failed to "produce his inventory" of photographs of Doherty.

He is also said to be "14 months delinquent" on a request to give copies of all photographs of Doherty to her estate no later than September 1, 2024.

And, while Iswarienko was to buy out Doherty's share of a Mooney M-20 airplane for $100,000 and pay that sum to her estate within five business days of the sale, he allegedly "unilaterally withheld $50,274" after making the sale.
