If a document isn't stamped (either with a notary seal or required tax stamp), it can become invalid, inadmissible as evidence in court, or lead to penalties, depending on the type of document and jurisdiction; notarized documents lack authentication without the notary's seal, while tax-stamped agreements might be deemed unenforceable in legal disputes, though the underlying agreement itself isn't automatically void, just harder to prove.

Can a document be notarized without a stamp?
