No tienes parte ni suerte en este asunto.

- You have no right or portion in this matter.

Wow, I would never have guessed "portion" from suerte. (Well, I suppose for that matter, who uses the word portion anymore?) Is this some sort of "stock" phrase in Spanish?
 

I was trying to work out the sentence using "luck" before I read the English translation. My dictionary does give "fate" as another translation of suerte, so perhaps that is the context in which the word is used?

You have no fate (outcome) in this matter.

Maybe similar to the English idiom, "You have no dog in this fight."

Hi guys,

Yes, it is definitely a Spanish idiom; as Dan said, similar to "You have no dog in this fight". Or more direct or plainly "It's none of your business".

Thanks, guys!
