Basinger and Baldwin have been fighting over custody of daughter Ireland for more than three years.
Having finalized their divorce in Dec. 2001 after eight years of marriage, the couple settled on joint legal and physical custody of their only daughter, who lives in Los Angeles with her mother to attend school, while Baldwin, 49, lives in New York.
But accusations on both sides of violating visitation rights began to surface several years ago, with Baldwin accusing Basinger, 53, of having "a pathological need" to turn their daughter against him.
Basinger's attorney, Neal Hersh, meanwhile, has said that Baldwin suffers from "severe emotional problems" and that he had been accused of domestic violence in the past.
A court hearing is set for May 4.
