There are normally two parties in a divorce.
The Petitioner – this is the person issuing the divorce.
The Respondent – this is the other party to the marriage.
There can be a third party to divorce proceedings called the Co- Respondent.
If a divorce is proceeding on the grounds of adultery you will need to name the person with whom your spouse is having an affair. They are called the Co -Respondent. They will also be served with the same divorce papers as the Respondent and they will need to sign and return these papers to the Court.
