Sending a Cease and Desist fax?

I would do this to supplement return receipt mail, but I would not rely on a fax alone. If you use both ways, it would be harder for the recipient to lose/misplace it. Should you go to court, two different, nearly simultaneous methods would be about as infallible as you could get-and it shows you mean business.

Also, I've had faxes lost due to memory issues with the fax machine.

ok- I have never sent faxes I just wanted to know if anyone has ever tried it and it worked. thanks for the help

I've used faxes in the past, and they almost always work as well as a letter sent CMRRR, but there is the occasional risk of the fax that gets "lost". *cough cough* Of the dozen or so faxes that I sent for C&D, that only happened once, but it's still annoying.

Also, more importantly, you have no proof that they received the fax, which is why I ultimately decided not to use faxes anymore.

Ok just stictly hypothetical here, but if I were to send a fax from a place like Office Depot, they usually give me a confirmation slip that the fax was sent. Is that good enough proof?

You should be able to show proof of the actions taken, whenever requested. If you have the receipt of the fax getting delivered to a specified number, it works.
