What is the test for standing to challenge a search warrant?

The district court held the Bergquists lacked standing to challenge the warrant because it was directed at a third party. Neither the Government nor Cochise County presses this point on appeal, but we note that the Bergquists have standing to challenge the execution of a warrant upon their property because they meet the test of having a "legitimate expectation of privacy in the premises" of their rural residence.
