A will does not have to be notarized to be valid. Holographic wills are one example. In many states the will has to be witnessed, but does not have to be notarized.
Yes. The principal's signature must be witnessed and notarized for a valid Power of Attorney. See link below for more information about POA in Illinois.
Your question is a bit confusing. A notarized signature is either done properly or not at all. I am a notary and you can't make an improper notarized signature. Also, who told you it wasn't properly notarized and what made them say that? I know more questions than answers but to give you a valid answer these need to be clarified. Shepherd 564
A notarized document never expires. It is always a valid document.
The first signs it and has his/her signature notarized, sends it to the second, and the second person signs it and has his/her signature notarized.
An agreement does not get notarized. A signature does. Most contracts do not need notarized signatures to be binding.
In general, all signers of a document do not have to be in front of a notary at the same time. However, each signer must appear before the notary when they sign the document to have their signature notarized.
Yes, needs to be notarized
It depends how close a relative. If its your spouse, then almost certainly not. The notary cannot have any stake in the transaction. Familial relationships would likely guarantee a conflict of interest. This is a common problem with notarizations generally. The signature is valid, and the transaction notarized could be valid, but it is certainly not best practice.
No, unless it is stated otherwise on the notarized document. In cases of power of attorney all POA's become null and void upon the death of the grantor regardless of how the POA was implemented.
In most states, a CPA does not have the authority to notarize documents. Notarization requires a notary public, who is a designated public official. It is important to use a licensed notary public for this purpose.
The notary seal and notary's signature does not make a document a binding contract. The signatures on a contract can be notarized. However, when a document if notarized, the notary is simply stating that to the best of their knowledge the signature is that of the person signing the document. In other words, the notary verifies a signature that they witness. A contract would be binding once the participants sign it in front of the notary and the document is notarized.
