"Wait Till Daddy Gets Home!"
This familiar parenting cliché is not only another kind of threat, it's also diluted discipline. To be effective, you need to take care of a situation immediately yourself. Discipline that's postponed doesn't connect the consequences with your child's actions. By the time the other parent gets home, it's likely that your child will actually have forgotten what she did wrong. Alternately, the agony of anticipating a punishment may be worse than what the original crime deserved.
Passing the buck to someone else also undermines your authority. "Why should I listen to Mom if she's not going to do anything anyway?" your child may reason. Not least, you're putting your partner in an undeserved bad-cop role.
