Lindsay Lohan's father is seeking a conservatorship for her.

Michael Lohan is convinced his daughter has resumed abusing drink and drugs and after trying to stage an intervention on Friday he is trying to go through the courts to get a conservator appointed to look after Lindsay.

Michael claims his daughter is hanging out with the wrong people, including her mother, Dina Lohan. He is not requesting he be made conservator - an appointed person who has legal control over the subject - as he doesn't want to be in control of Lindsay's finances, so people can accuse him of going after her money. According to website TMZ, Michael wants a judge to decide who to appoint conservator, but he says he will not accept Dina.

Michael has told his lawyer the first thing he plans once there is a conservatorship in place is to convince them to send Lindsay to rehab. He claims every time Lindsay has been to rehab "she went in dirty and didn't come out clean."

He also blames the people around Lindsay for helping to fuel her addictions. He also believes he, Dina and Lindsay need to go for family therapy, which his ex-wife has refused in the past.

While many have accused Michael of interfering, his intervention on Friday had the full backing of Lindsay's legal team, including her lawyers and manager. Michael's intervention failed as Lindsay phoned the police and he claimed she also kicked out her boyfriend Josh Chunn, who tried to reason with her. She is now reportedly seeking a restraining order against her father to stop him from interfering in her life.
