Although anyone may create a deed poll and this company has no special legal status, this is still a highly significant piece of visibility activism and one of very few examples of forms offering a gender neutral title:

I just got this email from the awesome dude at the UK Deed Poll Service:

Dear Lotte,

Our website now accepts a change of title to Mx.

Fingers crossed in time it becomes a recognised British social title.

What a legend. :D And proof that writing emails and letters can change the world.

Go and get your Mx, people!

In the screenshot above, when you click the link that says “for more information about the title Mx” you get this text:

About the title Mx

In October 2011, we introduced the title of Mx (pronounced Mix) as an option for people who do not identify themselves as either male or female and, therefore, feel a gender specific title such as Mr or Miss is inappropriate and unsuitable for them.

We are unable to guarantee that all record holders (i.e. government departments, companies and organisations that hold your personal records) will recognise your new title but we believe many will and in time all will.  Initially, the problem will be record holders’ computer systems not being able to accept Mx as a title but when a significant number of people request record holders show their title as Mx a tipping point will be reached causing record holders to reprogram their systems to accommodate Mx as a title.
