You will need to personally appear at least three times. The first will be before the city or provincial prosecutor during the investigation for collusion between the parties. The second will be during the pre-trial stage. If you have executed a special power of attorney in favor of your lawyer authorizing him/her to appear in your behalf for the pre-trial, then you need not attend the pre-trial stage. This is usually allowed if the petitioner is working abroad. The third time is when you will be presented before the court to give your testimony about your marriage and your relations with your spouse.
