A notary seal does not validate the contents of a document.

When you have a document notarized, the notary is not responsible for the contents of that document.  The notary is not authorized to suggest or make changes on a document.  So it is important to remember that as a signer, your liability as to the contents of that document are indeed under your approval.  

Sometimes a client will request for a notary to provide a document for their signature.  This happens often with power of attorney docs.  There are a variety of sources that provide blank legal documents to the public, but it is the responsibility of the signer(s) to ensure that it meets whatever purpose or intent that it serves.  We highly recommend that the public seeks the advice of a licensed attorney, to ensure that it meets the desired purpose.  A notary is not allowed to offer legal guidance, unless they are licensed to practice law.

Some sources, such as TexasLawHelp offer free information and documents that you can download without having to seek an attorney.  While this is a convenient do-it-yourself option, your situation may require a more complex legal approach.  Be sure you read any document before you sign it, and if you don't feel comfortable with it, do not sign it.

When you request a notarization, the notary is validating acknowledgements or oaths as to the truthfulness of the contents.  The burden of liability therefore lies with the signer, and the signer should always make sure that what they are signing is worthy of their hand signature.
