In every respect there is no such thing as self-notary.
1) notaries cannot notarize their own material,
2) notaries are constitutional officers of the state they have an oath of office, non-people cannot do that
3) a notary must legally know their signers, this knowing process varies from state to state, in Florida for example it requires that you identify the signer with prescribed ID, if you don't know them personally;
4) in many states many notary acts cannot be done for close family members -- presumed conflict of interest,
for the above reasons fundamentally the whole idea of "self-notary" is wrong.
