If you were never married to the child's father then the law vests custody of the child to the mother. If the father has filed for legitimation of the child, then he probably has a court ordered custody and visitation schedule. If you should move under thoses circumstance, then the biological father could seek to either obtain physical custody (which probably would not happen if he has a substance abuse problem) or he could seek to modify the court ordered visitation periods, seeking to make his visitation periods during summer or holidays.
