I’ve taken the plunge after trying it out on Facebook and Twitter for a few months, to change my surname to “West”. This is a shortening of my husband’s surname to be more palatable to the Canadians. Plus it’s two letters shorter than my old one.
There are at least three ways to change your last name, and I’m using the “common usage” method. I get everyone to call me by my new name, and in time I’ll ask the government to change my ID documents to match the new name. It’s fairly straight forward.
