My partner and I are similar to you. We couldn’t care less. I proposed to her, she said yes, we’re happy with the way things are, nothing needed to change.

However. Legally speaking, when you get married, you are considered as a single legal entity in many things including court/law enforcement/taxes.

A person cannot be compelled to bear witness to their partners actions in court, in the USA, that’s the fifth amendment, in Canada, it’s section 11© of the charter of rights and freedoms. The basic concept being that you have the right to remain silent (and not incriminate yourself).

While I don’t plan on doing any crime or anything… That’s a nice perk.

Also, she hates doing her taxes, so when we’re married, I can do taxes for both of us.

There’s very few perks here and bluntly, it’s not worth the cost…

We’re going to elope and just throw a “reception” (party) afterwards.
