When you have a warrant on you, the police will arrest you if they see you. You won't be able to talk the police into not arresting you. They do not care if the charges against you are false, all that matters is that you have a warrant and they will arrest you. Do not speak to the police about your case; they don't want to hear your side of the story and will try to get you to admit some wrongdoing that can be used against you at later. The time for you to tell your side of the story is at trial. I advise you to hire a lawyer to go with you to the court that issued the warrant and remove the warrant. The longer you wait, the less likely the judge will release you after you remove the warrant. Handle the criminal charges against you with the help of the lawyer, who will investigate the allegations and devise a strategy to defend you at trial. Abide by the terms of the restraining order: the issuance of a civil restraining order against you is not a criminal action, but violation of that civil order is a crime. Good luck.
I agree with Mr. Pang. Hire an attorney and let him/her speak on your behalf. He/she will also be able to surrender you on the warrant without too much difficulty to you.
I too agree with Atty. Pang as you should have your lawyer do the talking for you. You should have the warrant removed by appearing in court with your lawyer and promising to return on the next scheduled date. Please do not contact or attempt to smooth things over with your mother at ths time as any contact could be charged as a criminal offense.
