Who can challenge the validity of a notarized document?

The validity of a notarized document can be challenged by any interested party. An interested party is defined as anyone who has a legitimate stake in the matter related to the document. This includes individuals or entities who may be affected by the contents of the document or have a relevant interest in the transaction it pertains to.

For example, if a notarized contract is in question, any party named in that contract, or any party that may have legal standing in relation to the contract, can challenge its validity. This broad definition allows for multiple stakeholders to seek legal recourse if they believe that the notarization process was compromised or if there are issues with how the document was handled.

The other choices are more restrictive and do not encompass the full range of individuals or entities that may be impacted by a notarized document. Therefore, the selection of any interested party as the correct answer reflects the inclusive nature of who may rightfully challenge a notarized document's authenticity.
