The Respondent has an attorney: You can, and probably should ask the court for a continuance to give you the opportunity to seek legal counsel or get your witnesses.
Your witness does not come to court: You can, and probably should, ask the court for a continuance so that you can have a witness present.
The judge asks if you and the Respondent will agree to an Order of Protection "without a finding" of abuse: This is up to you, as the Petitioner, to decide and tell the judge whether you want to agree to this. A "finding" is what the court writes in at the top of the order if a full hearing is held and the court believes that the abuse happened. An example of a "finding" might be: "The Respondent hit the Petitioner in the face and threatened to kill the Petitioner." An Order of Protection can be granted without this kind of information written down by hte judge if both parties consent. If the Respondent agrees to the Order of Protection "without a finding", then all of the restraining orders would be in place and would have the same effect as if there was a "finding". Sometimes having a "finding" writtten in might be beneficial to the victim in going forward with further family court or criminal actions.
If you want the judge to have a full hearing and want to make sure a "finding" is written on the order, then you do not want to agree to this. If you do not agree to this, then you will go forward with the hearing and the judge will then make the decision of whether or not to grant the Order of Protection.
