What Is the Mx Title in the UK?

The gender-neutral title “Mx” (pronounced Mix, Mux, or Məx, depending on personal preference) has been gaining traction in the UK as a widely accepted, inclusive alternative to traditional titles like Mr, Mrs, Miss, and Ms. While it’s not yet universally understood, Mx is increasingly seen on official forms and embraced by individuals who do not wish to identify with a specific gender.

In this guide, we’ll explain what the Mx title means, its origins, how it’s used, and how to update your title if you wish to use Mx instead of a gendered alternative.

What Does Mx Mean?

Mx is a gender-neutral title used by people who do not wish to be identified as male or female. It is especially popular among non-binary, transgender, and genderqueer individuals, although anyone can use it if they prefer not to disclose or define their gender.

Just like Ms is used without indicating marital status, Mx is used without indicating gender. It can be placed before a person’s first name or surname—for example, Mx Taylor Smith.

How Do You Pronounce Mx?

There is no single correct pronunciation for Mx. Common pronunciations include:

Ultimately, pronunciation is a matter of personal preference, and people using the title can choose how they'd like it to be said.

Where Did the Mx Title Come From?

Although the exact origin of Mx is unknown, the title has existed in some form since the 1960s. The first known printed use appeared in a 1977 edition of Single Parent magazine in the United States. Mx gained more attention in online forums during the 1980s and 1990s, particularly in the UK.

By the early 2000s, Mx became a popular option in UK trans and non-binary communities. Its use has steadily increased and is now recognised on many official forms and systems across the UK. In the 2019 Gender Census, over 31% of respondents selected Mx as their preferred title.

Is Mx Legally Recognised in the UK?

Yes, Mx is increasingly recognised by UK institutions and government departments. You can select Mx on forms issued by:

In 2015, the UK House of Commons confirmed that the title Mx is accepted by Members of Parliament, further cementing its place in official use.

Can You Legally Change Your Title to Mx?

You do not need to legally change your title through a deed poll. Titles like Mr, Mrs, Ms, and Mx are honorifics, not part of your legal name.

If you want to update your title to Mx on records or accounts, you can simply request the change from the organisation involved—just like women who change from Miss to Mrs upon marriage. There’s no fee, and it’s not a legal process.

However, if you're also changing your name (e.g. your first name or surname), you will need a deed poll to make it official and have it recognised by banks, the passport office, and other institutions.

Final Thoughts

Mx is a valuable option for people who want a respectful, gender-inclusive title in line with their identity. While not yet universal, Mx is widely accepted across the UK and is helping to modernise how we address each other in a more inclusive way.
