Is a planet posited in the house of the quesited, always a co-significator of the quesited, in addition to the planet which rules that house?

With the consequence that, in a relationship horary, if say:

Aries was on the 1st, Libra on the 7th and Jupiter in the 7th, and there were no aspects between Venus and Mars (and no translation/collection), but there WAS an aspect between Mars and Jupiter - would that still indicate relationship potential?

This is probably a very basic question but, being new to horary, I can't be sure. Sorry in advance if this question has already been asked before!

Okay, yes the answer was staring me in the face on this site! Planets in or near the cusps of the 1st and 7th Houses are to be treated as co-significators.

Then I assume the answer to my question above is yes?? No aspect between main significators, but aspect between significator and co-significator = good relationship potential.
