Do annulment requirements change depending on who you are or who you know?

No. The name or status of the petitioner (the spouse requesting the annulment), the respondent (the spouse receiving), or any witness does not matter. Everyone is treated with the same procedural rights in church law. No one is penalized for being well known or for being unknown. Everyone is treated fairly and in accordance with the church law. In fact, no officer of the court is permitted to take part in a case in which there is a family relationship, close friendship, animosity, desire to profit, or avoid a loss. This law exists to protect the integrity of the process and to avoid any suggestion of collusion.
