Hi. I'm from Ontario Canada. My little girl had a child 7 months prior, and isn't 100 percent sure of paternity as there are 2 possible dads. The one potential dad is a completely criminal and we don't need him anyplace close to our child kid. He is obstinate on seeing him, and we have let him know a few times that we won't allow him access except if he gets a court request for a paternity test, and we are requested by an adjudicator to do as such. He is asserting that his legal advisor has prompted that we are keeping his child from him and that this will hurt us in court. He has been to prison for aggressive behavior at home on a past sweetheart, and illegal exploitation. He additionally punched my most established little girl in the eye and gave her a bruised eye when she attempted to prevent him from pushing my most youthful little girl around. My inquiry is, the thing are our commitments lawfully. Is it true or not that we are permitted to decline to address him, and keep on denying admittance to the child without a paternity test?
