I suppose there is nothing written anywhere that lists specific reasons where one can get it done or specific reasons where a judge should recuse himself. How do you know if a judge is going to be unbiased until after he has made a ruling?
Unfortunately you don't know until he rules. I've BTDT. I tried for 8 years to get our judge to recuse himself. He was/is dating(living with) my ex's mother. He would never enforce CS nor raise it over the years although the ex's wages grew tremendously. After 8 years and my attorney FINALLY filling with a complaint with the AG's office, he recused himself.
It's aggravating, believe me I know. But until he rules, you don't know if he is biased or not.
