1. Joe has recently been admitted to the bar. Attorney Dan hires Joe as an Associate to supervise the work of Sally, the paralegal who has handled title searches in Dan's office for the last 10 years. Joe is to review Sally's searches for accuracy, to handle any legal questions that might arise, and to sign off in Dan's name once the title searches are accurate.

Which of the following is true:

1. It is proper for Joe to assume these responsibilities because he is an attorney, and Sally is highly experienced in title searches.
2. It is improper for Attorney Dan to assign this role to Joe unless it will significantly lower his client's fees for title certification.
3. It is improper for Joe to assume these responsibilities as he may not sign documents using Dan's name.
4. It is proper for Joe to assume these responsibilities because Attorney Dan is ultimately liable for the accuracy of the title searches.
