I cannot tell from what you described what you and your mother signed, and I am not sure what you mean by a "Life Trust". However, there is no question that you have a right to see copies of the papers you signed. Call the lawyer's office and request that copies of the documents be sent to you by email within 24 hours.
There is no base-line '3 day rule' but you do have a right to receive copies of the documents. I'm not sure what the lawyer had you signed and simply not having the documents ready for you to review is not misconduct. If you don't feel right about him/her then I'd suggest getting a new one.
