I feel like i should know the answer but I don’t! My friends’ trans son has changed their name by deed poll and has a new passport where sex is now shown as female. They do not pass as a woman. Currently they hardly leave home but hopefully that will gradually change over time. I am just wanting to know if the passport change means they can access female only facilities if challenged? Asking as their mental health is so fragile I’d think they need to be well prepared for whatever is the likely outcome.
