Just for clarity - is this course material saying that a defendant/accused has to go find a notary public to sign every little thing? Sounds like it can get expensive fast. (verification statements for this or that, individually certifying service of each motion or memorandum or discovery request, etc.)
If not, whew, that'd be a relief.
But if so, then what is the best way to do all that on the cheap? If you live way out in the country, even finding and travelling to meet a notary public can be a pain, not to mention whatever the notary public charges per signature.
