Apollo 11 moonwalker Buzz Aldrin, is suing two of his children and a business manager, accusing them of misusing his credit cards, transferring money from an account and slandering him by saying he has dementia.
Court-appointed mental-health experts will evaluate the competency of Aldrin this week as two of his three children try to become his guardians, claiming he suffers from memory loss and confusion.
The evaluations took place Tuesday and will take place again Wednesday.
Aldrin’s children, Andrew and Janice, filed a petition in Florida state court in May, claiming their father was incapacitated. They claimed he was associating with new friends who were trying to alienate Aldrin from his family and that he had been spending his assets at "an alarming rate."
In April, the 88-year-old Aldrin underwent his own evaluation conducted by a UCLA psychiatrist, who concluded Aldrin was capable of managing his own finances and health.
In the lawsuit filed earlier this month in a Florida state court, Aldrin asked a judge to remove his son, Andrew, from control of his financial affairs, social media accounts and several nonprofit enterprises.
Aldrin says his daughter, Janice, did not act in his financial interests, and he accuses his manager of fraud.
Aldrin was a member of the Apollo 11 crew which landed the first two humans on the moon. Aldrin joined Neil Armstrong on the lunar surface in 1969.
