I just want to ask how to process anullment...

If you want to initiate any legal procedure, including the annulment of contracts or even divorce without your personal presence through the person in charge of making a power of attorney for anyone to represent you in undertaking the legal procedures that you want to take and this agency is organized at the court by going to the authentication section and then filling out the agency's form, and after completing this procedure, the other person can carry out the legal procedures on your behalf.
