To sue someone, you need enough evidence to prove your case by a "preponderance of the evidence," meaning it's more likely true than not (around 51% certainty), not "beyond a reasonable doubt" like in criminal cases. You don't need all proof upfront, but should have strong items like receipts, contracts, photos, videos, emails, or witnesses to show the other party caused you harm, with quality evidence often better than quantity.
