Capital gain tax between ex spouses

Hi there, I separated from my ex husband in November 2022. He put my name on one of his properties during our marriage. After our divorce, I trasferred my 50% share of the property back to him. We believe we're qualified for the no gain/no loss relief for capital gain between ex spouses for 3 years. Is that correct? Do I need to do anything to report it and claim the relief or it's automatic? Many thanks
