When should you use desertion as a reason for divorce?
Consider the logic of the situation. If the person bringing the petition does not accept the relationship is over and does not agree to the other person leaving, then why would they want a divorce or dissolution? To proceed with either you have to show the relationship has broken down irretrievably and in this instance they have not accepted that.
While there may be rare cases where desertion is proved, if the Petitioner accepts the relationship is over, it is much more likely the divorce will proceed on the basis of 2 years separation by consent.
