What happens if a signature is not witnessed?

If a signature isn't witnessed, the document might still be valid, but it loses significant security, making it vulnerable to challenges about fraud, coercion, or disputed identity, especially in court, as witnesses provide independent verification that the signing was legitimate and the person understood the terms. While some documents (like basic contracts) don't require witnesses and are valid if intent is clear, others (like wills or property deeds in certain areas) do require them for legal enforceability, meaning an un-witnessed one could be void or hard to prove.
