In which situation does a notary have a disqualifying interest?

A notary has a disqualifying interest in a situation where they are named as the beneficiary in the document. This creates a clear conflict of interest, as the notary would stand to gain personally from the transaction, undermining their impartiality and the integrity of their role. By law, notaries are required to be unbiased and impartial; therefore, any personal interest or financial gain in the outcome of the document they are notarizing makes their notarization invalid.

In contrast, situations involving family members, merely being a witness, or being mentioned in the document do not automatically disqualify a notary from performing their duties, as these scenarios do not inherently conflict with the need for unbiased and impartial service.
