Contact an attorney and ask for assistance in filing a motion for immediate parenting time and perhaps even for custody. You need to find out what your legal rights are at once. Good luck to you.

You will need to seek court assistance by either filing a complaint for custody yourself or by filing a motion if your ex girlfriend has already filed the complaint. Either way you should consult with an attorney as soon as possible in order to secure your rights to your son and start seeing him on a regular basis. This response is general in nature and is not legal advice. No attorney client relationship is formed by it. Good luck.
