Our SOP is a bit vague and may contradict itself as to whether a cabin jumpseater needs all the paperwork. SOP is clear that they do need to check in with the CA.

I don't check the docs for a cabin jumpseater because I don't think anyone cares, and the SOP probably did not intend that. But I wouldn't blame someone who felt the need to dot i's and cross t's either.

When I get a 135 pilot I do check our reciprocal list, because half the time they're not on it. While I might let such a person in the cabin, no way are they sitting in the actual. It pizzes me off that they even ask because they know darn well whether they have an agreement with us, and they should know I could get fired for letting a random non-authorized person in the cockpit.
