If the agreement (contract) was signed in the presence of a Notary Public, no.
You are a witness to the signing of a signature on the document and nothing else, (unless it is stated that you are a witness to something else involved with the legal matter directly above where you will sign the document as the witness.)You do not have to know what the document says, what or who it is about, or anything else about the document in order to be a witness to the signing of the document.You are only a witness to the 'original signature' that was signed on the document and could be asked to verify the original signature, as well as your own signature, by anyone involved in the legal process.I would recommend you Do Not ever sign as a witness unless you are certain the signature is valid and it was signed in front of you.
The only responsibility of a signature witness is to verify that the correct person is signing the document. The person must physically sign the document while the witness is watching.

Expert witness testimony is essential to most medical malpractice cases. In all cases these malpractise cases require a medical witness and usually the most qualified.
It depends on the state where you live. In Texas, for example, a medical power of attorney needs either (1) the signature of two persons who witness the subject's signature, OR (2) it needs to be notarized by a Notary Public who witnessed the subject signing the medical power of attorney. It does not need BOTH the witness signatures AND the notarization. But in almost all cases, it is a good idea to get the document notarized even if you have two witnesses. It reduces the possibility that it will be challenged.
That is what Notaries DO. They witness and substantiate the signatures on the document as being valid.However, the simple act of notarization does NOT make a document a "legal" document.In the case of a will - the Notary's only function (IF notarization of a will was even required by state laws) would be to ensure that the signature of the testator was genuine. The purpose of witnesses to a the signing of a will is if the signature of the testator happened to be challenged at probate, the witnesses could be called upon to verify that the signature actually was the decedents.
