Describe the posture — "long marriage, disabled spouse, indefinite alimony" — and get published opinions ranked for your facts. The relevance filter has one hard rule: off-point candidates are omitted entirely, never mentioned and hand-waved away. What you see is what's worth reading.
Every result opens as the full opinion, in place, with the passages matching your facts highlighted. Save the keepers to the matter.
Paste a brief and every citation is resolved against the live opinion corpus: does the case exist, does the quote appear, does it stand for the proposition. Run it on your own drafts before filing — and on opposing counsel's the day theirs arrives. A fabricated cite in their response is a very good day for you.
Factor lists, adjustment bands and schedule provisions live in a corpus checked character-for-character against the published code. When Lex or the research tools quote statute, they quote this — which means the language in your brief is the language in the book, every time.
Next: turn the authority into filings
