Any notary can notarize a signature on a will. However, a will also requires the signatures of witnesses to make it valid. In most cases you must have two witnesses to the testator's signature.
No. There is no state where you can notarize your own documents.
No, a Maryland notary cannot notarize a Washington DC document. A notary public is only authorized to notarize documents within the state where they are commissioned. To notarize a Washington DC document, you would need to find a notary public who is commissioned in Washington DC.
No. An Indiana Notary Public can only notarize in the county in which they are commissioned.
No.
The authority to notarize is granted by the state. If the documents are signed in West Virginia, the notary can notarize them.
A New York State notary can refuse to notarize a document if he or she believes the document is fraudulent or that the signatory has not established his or her identity to the satisfaction of the notary, or if the signatory has not paid the $2 fee. A notary cannot refuse to notarize a document for discriminatory reasons.
A notary can notarize the signature if it is signed in front of them and done in the state where the notary is licensed. Where the signing person lives does not matter.
Notaries do not notarize documents. They notarize signatures, and they are only permitted in the state by which they are licensed. It does not matter what the document is. If the document is signed in Pennsylvania in the presence of a Pennsylvania notary, that notary can notarize the signature. If the document is signed in any other state, or outside of the presence of the notary, the notary cannot notarize the signature.
A New York notary can notarize anything executed in New York. They cannot do so in another state.
In any U.S. state that I am aware of, you cannot notarize your own signature.
If the Notary's name appears anywhere in the body of the document that they are asked to notarize, they may not notarize the document due to the appearance of a conflict of interests.
Generally, a notary can only notarize signatures while in a state in which they have a notary commission, for the most part. Notaries can hold commissions from multiple states (in some cases). Some states also provide reciprocity to other states, meaning a notary from one state can legally notarize documents in another (although this is not common). Whether they can notarize wills or not is another question. They almost certainly can, if they can notarize at all. Unfortunately, you will need to check your state laws to be sure.
