In early April, a new client, Lucy Meade, comes to your office and asks you to prepare a joint return for her and her husband, Albert. They are visiting your city so that Albert can obtain medical treatment for a serious mental disorder. You suggest filing an extension so that they can have the return prepared on returning home. Lucy adamantly opposed an extension, however, as the idea of being late on her taxes frightens her. Since Lucy seems to have brought all of the information needed to prepare the return, you accept the engagement. Do you sign or not sign the tax return?
