Do you see the child now and if yes how often?

We need agreement with Maria. If not, to do so in order to proceed you would need the proves of bad upbringing of your child the existence of physiological or physical harassment from your ex-wife toward your child.

Every fact of abuse should be documented. If you believe that your ex-wife is mentally incompetent than such facts should be medically documented as well.

For time being you can participate it the child’s life.

By default, both parents have equal rights to participate in the child life. You can request the court of law to schedule the time and frequency of visitation. If your ex-wife fails to follow this court order, you may have some grounds for obtaining the custody of your child.

This way is so long and expensive.
