My despair began when I had a mountain of evidence of drug addiction
The type of evidence that keeps your child out of the hands of a drug addict is evidence that is created and maintained by a disinterested party. What was your evidence? Is the mother still a drug addict?
Did you have a court order for hair follicle, blood and urine drug tests to be conducted on both of you?
Did you have documentation of hospital admissions for drug overdoses?
Did you have documentation of CPS findings that indicate that the mother was neglecting or a danger to the child?
Did you have criminal records of convictions for possession of drugs or driving while under the influence?
Did you request that the court order a full custody evaluation, including psychological evaluations and substance abuse assessments?
