Daniel Baldwin has filed for divorce, one day after getting a temporary restraining order against his wife, Joanne ... and he claims it's all over drugs and alcohol.
Daniel says, "Due to recent events in our home and for the safety of my children and myself, I have made this decision."
Daniel adds, "I have had my share of problems with drugs and alcohol many years ago and know first hand how difficult a position she is in."
The couple married in 2007. They have 2 kids. The judge who issued the restraining order gave Daniel temporary custody.
