ok, but this is a court case question! :-D Saturn is stronger than moon in essential dignities but this only shows us the justice of the case. So in reality you should win. However the moon is accidential stronger, that's why he seems to has the upper hand for most of the time. BUT the 4th house (the judgement, outcome) ruler is venus and in mixed mutual reception with Saturn. On the other hand venus and moon don't receive each other in any dignities.(=good for Saturn). Mars (the judge) will soon enter in Libra, where he will be in Saturn's exaltation, triplicity and term and only receives the moon by face, i.e. the judge "likes" you more and he will decide for the one he likes more. However Saturn's only aspect is a square to the sun. Leo is intercepted in the 7th house, so we can use Sun as his second significator. Maybe you both will try to reach an out-of-court settlement. The moon as his significator will make a sextile with Venus, which technically must mean that he will win at the end, but this could be prohibited by the moon-jupiter conjunction. Jupiter is your 2nd house (money, lawyer, witness) and is received by moon- we can say that Jupiter has the control over moon. It's not an easy chart. On the whole I tend to say that you will win.
