Hayden Panettiere's family is supporting her former fiancé Wladimir Klitschko's petition for guardianship over their 11-year-old daughter Kaya's estate. The late actress's family doesn't plan to challenge Kaya's inheritance after her former fiancé Wladimir Klitschko recently filed for guardianship, 'Us' can confirm. 'TMZ' was first to report the news. Klitschko submitted paperwork earlier this month, requesting to be the temporary guardian of his daughter's estate. When Panettiere died in August, Kaya was the sole inheritor of the 'Nashville' alum's assets. As Kaya is a minor, the court could appoint a guardian while the case is in probate. Panettiere and Klitschko were together on and off from 2009 to 2018, welcoming Kaya in 2014. The 'Heroes' actress ultimately relinquished custody of Kaya to Klitschko following their 2018 breakup, occasionally visiting her daughter overseas. Klitschko and his daughter primarily live in Ukraine.
