so-called "misgendering" is not included in any aspect of UK law, be that civil law or criminal law;
so-called "deadnaming" is not included in any aspect of UK law. be that civil law or criminal law.
In fact, the Gender Recognition Act 2004 requires "deadnaming" when it comes to the Birth Certificates of any child who has a parent who "transitions":
GRA 2004 Section 12: Parenthood
[the name and sex of the parent cannot be changed on the Birth Certificate of any child]:
Parenthood
The fact that a person’s gender has become the acquired gender under this Act does not affect the status of the person as the father or mother of a child.

So the issue of "dead-naming" is a load of bollocks that the Trans Lobby is intent on gaslighting our entire society about.
