In new legal documents obtained by ET on Tuesday, Chick appears to have "changed his mind" about relocating to New York City, where Baccarin films her Fox show, Gotham, so the two can co-parent their 2-year-old son, Julius, in the same city. The papers say Chick, who was married to the 36-year-old actress for three and a half years, decided to return to Los Angeles with his son after he learned that Baccarin "had a new boyfriend," her Gotham co-star, Ben McKenzie.
In September, a Los Angeles judged ruled in the actress' favor that she could move her son to New York and, according to the new documents, she rented her ex an apartment for $6850 a month in the Big Apple so they could co-parent there. Baccarin and Chick share legal custody of their son, though she is the primary caretaker.
After their split over the summer, Chick "shipped some furniture there and actually stayed there with the child for approximately two weeks in July."
Baccarin is currently pregnant with McKenzie's baby, and says for "medical and financial reasons," it would be easier for her to have Chick visit their son in NYC than her travel to L.A. The document suggests that Julius return to California every two months for eight days to visit his father.
A hearing on child and spousal support is set for Nov. 19.
A source told ET when news broke of Baccarin and McKenzie's relationship that Chick was taken aback by the news. "Austin was totally shocked when he found out about the affair," the source said. "Totally blindsided. When Morena left him for Ben, Austin was devastated -- completely shocked."
