That is entirely up to you. Some persons feel more comfortable hiring their own attorney and others simply cannot afford the cost. The judge conducting the hearing will be conducting a court of inquiry. Therefore, the judge will be asking a majority of questions if you do not hire your own attorney.
If a warrant is issued at this hearing, then a formal charging document will be filed. Thereafter, crime victims are represented by either an attorney with the District Attorney's office for felony offenses or a member of the Solicitor's office for misdemeanor offenses. However, until that charging document is filed, neither the District Attorney's office nor the Solicitor's office is present at a warrant application hearing.
