A contract or legal agreement containing a photocopied or faxed signature is deemed valid and enforceable in most states. Such a document could be used to prove the existence of a contract in a court of law or in an administrative proceeding.
If the validity of a signature is called into play, the original document could be valuable to verify conformity to the copied or faxed signature. Again, however, the copied or faxed document should be sufficient to establish the existence of a contract.
In some cases, however, faxed or copied signatures are not appropriate â€“ for example, a county recorder\’s office or register of deeds usually will require an original signature on a deed or a memorandum of lease prior to filing the same “of record.”
Similarly, in those jurisdictions where cognovits notes are valid, the note filed with the court to obtain judgment usually must contain the original signature of the maker of that note.
