"¿Mi esposa vive aquí?"

Probably this is a story of a husband whose wife had been missing for years and he had just found her.

Then report it. I hope I am not coming across as rude, but unless you have a question about the sentence, please do post mistakes/missing translations here. If you are wondering if there is a mistake, and want to open dialogue about it, please post, but please ask a question.

(completely understands the irony of posting this rant)

I disagree. Because it's feminine, I believe esposa always translates as wife. Now esposo, on the other hand, could be husband or spouse, i.e., Ladies and gentlemen, please take your spouse's hand. Damas y caballeros, tomen Uds. la mano de su esposo, por favor.

Because it's the wrong word order for English. You can either say 'Does my wife live here?' or 'My wife lives here?'. The second construction is not usual.

Sure. It has question marks.

She left him and he's trying to find her.

Or he tells his love affair where his wife lives !
