The Guardian Ad Litem continues to contact the mother on behalf of the father after the case has been heard and we are waiting for a decision from the judge concerning child custody modification . The GAL has been extremely biased in favor of the father and the mother has been advised by her attorney not to respond to the GAL while the case is being decided . The GAL is also requesting more money even though the father is the one contacting him . Furthermore , the GAL has written letters outlining the father's allegations ( none of which have been proven ) to the judge while the case is being decided . Are there legal steps the mother can take against the GAL and what evidence is needed to prove bias ? The GAL also represented the father in a separate case even after being appointed as GAL .
