Example, the supreme court of Manitoba is now called “The Court of King’s Bench” – but the URL still says queen: https://www.manitobacourts.mb.ca/court-of-queens-bench/
Double takes abound. There should be a non-gendered form to use. “Court of Monarch’s Bench” or something ;)
Barring anything substantial changing we’ll have kings for at least the next 70 years (George will be about 80 by then)
