On 6 April 2022 the provisions of the Divorce, Dissolution and Separation Act 2020 (DDSA 2020), came into effect. Although DDSA 2020 does not make substantive changes to the law regarding nullity proceedings, there are some consequential changes to the procedure under the amended Family Procedure Rules 2010 (FPR 2010), SI 2010/2955 affecting applications for nullity and nullity of marriage orders that are issued on or after 6 April 2022.
