Have you considered the advice here:

By definition, a Notary is an unbiased official witness who is personally or professionally unaffected by the document. In legal disputes signers and attorneys may attempt to discredit a document on the grounds that the Notary had a financial or beneficial interest in the transaction.
For this reason, never notarize your own signature or a document in which you are personally named. If you will receive a direct benefit, fee, commission or advantage other than the fee allowed by state law, you also should not notarize. Similarly, if you stand to suffer a direct financial loss from a transaction, you should not notarize.
Notaries also should refuse to notarize for close family members because a Notary’s impartiality can be questioned in these circumstances as well.
