Chiyuv of Knas Starts with Judgment
- The chiyuv (obligation) to pay a knas (fine) starts only when the person is officially declared liable by Beis Din.
- Even if the act was done earlier, before the formal judgment, the liability doesn't exist yet.
Knas Liability Requires Beis Din Enforcement
- Liability to pay a knas, unlike monetary debts, does not exist until Beis Din makes the person officially liable.
- A person admitting to owing a knas before judgment does not trigger an obligation since the penalty must be enforced by Beis Din.
Tosafos on Knas vs Mamonot Liability
- Unlike mamonot (monetary debts) which are due immediately upon the act, knasos (fines) are tied to the formal legal process.
- Tosafos explains that by nefashos (capital cases) witnesses often contradict, so there's no liability until judged, contrasting with smooth cases like mamonot.
