What is the natural way to refer to in-laws of an unexpected gender?

Question

If my father's sister has a husband, I call him 고모부. If my father's younger brother has a wife, I call her 숙모. If my father's sister has a wife, what do I call her? If my father's younger brother has a husband, what do I call him? I understand that these family structures are not common in Korea but maybe one of these sounds more reasonable than another to a native speaker, or perhaps there is some alternate phrase that makes more sense. Even better would be a more general rule or practice, if there is one.

Answer 1

How you address someone depends on how they Identify. If they identify as a man then the usual he/him is appropriate and if they identify as a woman then she/her.

However, if are unsure then it is safe and polite to refer to the person in question as they/them.
