Still_Hopeful,High Priestess in a reading will often denote that a secret will be revealed, or more will surface because there are things hidden.
Your legal matter shows that you are entitled as shown by the 3 of pentacles, and that there could be a signing of contracts.
The 6 of swords is likely to see you being able to feel that you will have the matter put behind you, but there is a niggling doubt there that though you will sort things out for now, you may come back to the matter later just to make sure about something as you want to be certain that things perhaps are covered for all contingencies.
I think you have determined the reading yourself correctly as except for the feeling of waiting to exhale, such as your revisit to ensure things will be as they are supposed to be - yes except for that, you will most likely feel like you can put it behind you.
Eventually, with maturity, you will in time see this matter, though important now, for some reason, won't either bother you or seem as important down the track.

I think that's how it is, it's sometimes hard to put the sensations into words, as there is a lot of complexity here between actual threat/outcome and what you perceive as possible. I feel I might offend you in this though - as it seems there is a sensitivity to this issue - possibly a threat to aspects of your feminine self.
