I do have a GRC. It took me ages because the process is utterly ludicrous and I'm allergic to forms
I would just like to once again point out that although an individual applicant may well find the process ludicrous, this is the most successful such process we have ever designed in the UK.
More than 95% of all applications are successful. Applicants provide paper evidence from two healthcare professionals (one from their GP, one additional). These can be obtained privately at minimum fuss and for less than £500 if the NHS is too slow or the applicant's GP too reluctant to diagnose gender dysphoria.
After that, there is no actual evidence required showing any proof of living in one's "acquired gender" other than letters addressed to the applicant in a name that would be generally perceived as being for the sex the applicant wishes to be.
There is a quirk, however, in the application process. It was introduced deliberately to hide from the public the fact that no surgery is required to obtain a GRC - because of which even many of the smaller, and newer, trans rights organisations at first thought a medical transition was a condition for qualifying for a GRC.
And that quirk is that if an applicant says they have medically transitioned, they are then asked to provide evidence for that. This made the process onerous for the early applicants in 2004 and 2005, because many of them were post-op transsexuals who had transitioned many years before that and so struggled to provide the medical evidence. And to get a diagnosis back then was more difficult than it is today. So when the GRA was first enacted, you had lots of those post-op transsexuals share how difficult it was for them to secure a GRC.
This explains the difference in experience between those who found the whole process demeaning back then and those who secure a diagnosis of gender dysphoria today (which is not difficult if you know what to say and/or can go private), do not transition other than a name change and then apply two years after that. (The two year period is by far the most onerous condition, because there is no way around it.)
Neither of these applicants is lying - they are sharing real experiences of applying for a GRC, but the law does not need to be reformed to make the process easier or friendlier. It already is. And unlike any other applications to the state, applicants for a GRC can get help with their application from a civil servant.
