Nicolas Cage's Ex Sues Him for Enabling Son Weston Before Attack
Nicolas Cage Sued Ex Wants Him to Pay For Weston Attacking Her
update
2/21 6:45 AM -- Weston Cage's attorney tells TMZ in response to the lawsuit ... "Ms. Fulton’s decision to file a lawsuit against her own son is not surprising given her past history of litigation against family members.
He continues in the statement, "It appears to be nothing short of a money grab and call for attention. Ms. Fulton correctly advised the responding LAPD officers that her son was in the midst of a mental health crisis at the time of this incident. We will deal with this appropriately, and in a courtroom."
Nicolas Cage is far from Father of the Year in the eyes of his ex, as Christina Fulton is now suing him for fueling their son's violent tendencies ... which she believes led to him attacking her.
Christina filed the suit against Nic and their son Weston Cage over Weston's brutal alleged beating of his mother in L.A. last April. As you might expect, she's suing Weston for assault, battery, negligence and infliction of emotional distress -- but the legal twist here is she also thinks Nic's negligence played a big role in the abusive incident.

In the docs, obtained by TMZ, she says Nic was well aware of Weston's history of mental and psychological disorders ... but instead of addressing it, the actor enabled it. Christina claims Nic gave Weston financial support, bailed him out of jail multiple times, but never pushed him into getting any professional help.
Further, she claims Nic often went out drinking with Weston, while knowing full well he had substance abuse problems.
As we reported, Weston was arrested and charged for attacking his mother in a parking lot, elevator and lobby of his apartment building. The aftermath pics of Christina were horrifying ... and according to the suit, she suffered a concussion, multiple contusions, neck and throat injuries, and a disfiguring eye injury.
Christina says the attack has derailed her acting career and business ventures. She's seeking damages from Nic and her son.

Weston has pled not guilty to assault with a deadly weapon, but has yet to stand trial.
Cage's lawyer tells TMZ ... "The allegations by Christina Fulton against Nicolas Cage are absurd and frivolous. Weston Coppola is a 34-year-old man. Mr. Cage does not control Weston's behavior in any manner and is not responsible for Weston's alleged assault of his mother."
In response to Cage's lawyer's statement, Christina Fulton's attorney, Joseph Farzam, tells us ... "Nicolas Cage is responsible for Weston’s criminal behavior. Nicolas took it upon himself to provide Weston with a condo right next to his, when he should have had Weston in rehab under care and supervision. Nicolas enabled Weston when he kept bailing him out of jail, drinking with him, and taking him out of therapy and rehab. He instead provided his mentally disabled son with unlimited access to cash, knowing full well of his son’s propensity and history of violence. In doing so, he put my client and others in grave danger, which resulted in Ms. Fulton’s life long serious physical and mental injuries."
