Hi Stacy, some quick thoughts from an inexperienced novice…
Isn’t the querent (you) represented by the Ascendant (in Capricorn here)?
And isn’t the chart’s reference to the subject of the horary called the quesited, here the disputed bill/debt suggested by the Leo 8th House containing Moon-Mars.
However, here the rulers of the querent and quesited (Sun and Saturn) don’t contact each other – is this significant in terms of an outcome or lack of one?
Framing your question with a ‘should’ is so Capricorn.

But it doesn’t address whether or not you would win the dispute if you choose to fight it…maybe that’s a different question.
