Adultery is voluntary sexual intercourse between a man and a woman who are not married to each other but one of whom at least is married.

Proof of adultery is usually in the form of a written admission. When the respondent receives the divorce petition from the court there is an ‘acknowledgment¬†of service form’ to be completed and sent back to the court. If the respondent answers ‘Yes’ to the question ‘Do you admit the adultery alleged?’, that will normally be sufficient proof that the adultery has taken place.
