What is my cousin's husband to me?

Your cousin's husband is informally your cousin-in-law. He is related to you by marriage, not blood, and there is no official title.

There is no formal name; “cousin-in-law” is the usual informal term. Not a blood relative.

Most people call a cousin's husband (or wife) a cousin-in-law. It isn't an official title, but it's widely understood. He is not your brother-in-law; that's your sister's husband or your spouse's brother.

The same informal term covers your spouse's cousin.
