This is just my opinion: Do not use this as an official advice.
It just means you can’t do the signing without the present of an attorney. The attorney can be present via phone conference all through the whole signing process. But it is not something you need to worry about because the title company who hires you will set all up with the signers and the attorney! The only thing you need to make sure if witnesses are required and must follow the escrow’s officers instruction whether you need to find witnesses or the clients need to bring in witnesses.
Never proceed without talking and confirming with the title and attorney on every single items on docs.
I did one of these and it took me 2 hours! You have to be super confidence and must take control of the signing and close the deal successfully.
I only got paid $200. And I’m sure the attorney probably got paid a pretty good amount $$$$
