Anne Heche isn't going to sit back and let her estranged husband call her crazy. Or a bad mom, for that matter.

In court documents filed Monday in Los Angeles Superior Court and obtained by E! News, the Men in Trees star fired back at Coley Laffoon's contention that she was psychologically unfit to care for their five-year-old son, Homer, and accused him of resorting to "lies and distortions" in an effort to get more money out of her. (View the court documents.)

The 37-year-old actress has requested full legal and physical custody of Homer with visitation for Laffoon, while Laffoon has asked for joint physical and legal custody of the boy, plus $33,000 a month in child support. (Heche claims he has asked for closer to $45,000 in monthly support payments.)

Laffoon, 33, claimed in court documents filed last week that Heche's "bizarre and delusional behavior" and "poor parenting skills" made her a less than ideal mom and requested that she be forced to undergo an immediate psychiatric evaluation.

However, Heche cried foul on Laffoon's version of the incident he used as an example of her so-called delusional behavior, which occurred last September when she traveled from Vancouver to New York to make an appearance on The Late Show with David Letterman.

Laffoon claimed in his court documents that Heche called him from the Los Angeles International Airport, where she was supposed to make a connecting flight, sounding confused and saying she "didn't know where she was and that she needed help."

Because he was staying in Vancouver with Homer at the time, he said he was forced to dispatch her L.A. publicist to the airport to look for her, but that the flack's search was unsuccessful. He claimed that Heche came home the next day and acted as if nothing out of the ordinary had happened.

But as Heche tells it, she called her husband because she didn't have a copy of her itinerary with her and wasn't sure which airline she was supposed to be flying. She said that Laffoon had promised to find out from the production company, but had neglected to do so.

"It was midnight in Los Angeles. I didn't know where my connection was supposed to leave from, or on which airline," she wrote. "I started crying, it was very frustrating."

Heche also responded to Laffoon's allegations about her "poor parenting skills" by detailing her ex's habit of depositing their son at preschool or leaving him with nannies while he engaged in pastimes such as playing "ping-pong, backgammon and poker and view[ing] pornography online," and "going to strip clubs all day."

She claimed that Laffoon, an ex-freelance videographer, had sidestepped Canadian laws prohibiting children under five from attending school for more than four hours a day by enrolling Homer in two separate preschools, one in the morning, one in the afternoon.

"Coley claims that he is a stay-at-home dad and that this is by agreement," Heche wrote. "Coley does stay at home while I am working, but not to parent."

She said that she had shared the boy's care with Laffoon since his birth and that she spends "as much time with Homer as a working mom as Coley does as a so-called 'stay-at-home dad.' "

The actress went on to debunk numerous "false statements" made by Laffoon, including that she had allowed Homer to shower with her and her boyfriend and Men in Trees costar James Tupper and to sleep in bed with them, and that she did not put the boy in a car seat while driving.

"What Coley neglects to say is that the shower was a rinse-off shower near the swimming pool at the building where I live," the actress wrote. As for sleeping in bed together: "Homer has his own bed and he sleeps in it every night."

She admitted that she once allowed the boy to ride belted in her lap when she drove three blocks to take him to lunch, but said that he has a car seat that is "used routinely when he is transported by car."

Heche closed her declaration by arguing that her son belongs with her in Vancouver, where she lives and works, as she is his "sole economic support and [has] been throughout his life."

"Coley is unemployed and can travel at will to spend time with Homer," she wrote.

Laffoon and Heche married in September 2001. They announced their separation in January, and Laffoon filed for divorce on Feb. 1.
