* "Sheriff effect" is not a standard phrase. It's likely meant to be "sheriff effect service," but even then, it's not quite right.
* "Service" is used to describe the act of delivering a subpoena.
* "Effect" is not the correct word here.
Here's how to correct the sentence:
* "Can the sheriff serve the subpoena?" This is the most concise and clear way to express the question.
* "Can you have the sheriff serve the subpoena?" This is grammatically correct, but a bit wordy.
