demons or archangels for complicated legal issues?

i’ve been dealing with a nasty legal situation for a while and i recently started reading GoM Archangels of Magick. I wanted to ask anyone here who has dealt with heavy legal situations if they had worked with demons or archangels or even both to fix the issue. I also wanted to ask what GoM books I need to purchase and research for the specific rituals, thank you! also did any one use crisis magick for the legal situations as well?
