By getting a Decree of Nullity, the Court orders that the marriage never existed in the first place. There are a number of grounds for applying for such an Order and legal advice should be sought in the event that a client believes they may have reason to believe they are entitled to a Decree of Nullity.
If such an Order is granted by the Court, the parties are in a position to marry thereafter, as the Court orders that the previous marriage never existed. A Decree of Nullity will have different financial implications than a Judicial Separation or Divorce and these implications of such a Decree should be discussed with the legal advisor.
