If there is no outward obvious sign with a spell, do you automatically know if your spell is successful / failed?
For example: Dominate person. Would you simply know if your target failed our passed it's save?
Or Protection from X, would you automatically know if a creature pierced the spell before it hits you? ( a little different of an example )
Succeeding on a Saving Throw: A creature that successfully saves against a spell that has no obvious physical effects feels a hostile force or a tingle, but cannot deduce the exact nature of the attack. Likewise, if a creature's saving throw succeeds against a targeted spell, you sense that the spell has failed. You do not sense when creatures succeed on saves against effect and area spells.

Ha! I have gotten the better of you this time Claxon!
Darn it! But thank you thread ninjas!
However...
Fool Casting:
A master spy of 8th level or higher can trick an opponent into believing that she has been charmed or dominated. When the master spy succeeds at a saving throw against a magical effect that provides ongoing control (such as charm person, dominate person, or a vampire’s dominate ability), she can allow the spell to take partial effect. To the caster, it appears that the spy failed her saving throw, but the spy is not under the caster’s control. If the spell provides a telepathic link, it functions normally, but the spy is under no obligation to follow the caster’s commands. The master spy can dismiss a fooled spell as a standard action. Fooled casting can be used when the spy succeeds at a subsequent saving throw against an ongoing effect, such as that granted by slippery mind.
