What are the moral, religious, and promissory obligations of canon lawyers? Where canon lawyers are charged with

advis[ing] people about how to exercise their rights [as Catholics] and to fulfill their obligations in accord with [canon] law


and Canon Law is defined as

operates in service to the Church that has supernatural responsibilities ... [and is] the legal expressions of Christ's will for his Church


and yet, one does not need to be called to holy orders (be a priest) to be a canon lawyer


it is natural to question the moral, religious, and promissory obligations of canon lawyers.

Moral - Must canon lawyers live in accord to canon law to licitly practice? If not, is there a lesser law by which they must live?
Religious - Must canon lawyers be Catholics in good standing?
Promissory - Must canon lawyers make an oath before being licensed? If yes, what does that oath include?

Source of quotes
According to the aims of one [perhaps of only three] canon law schools in North America, Saint Paul University in Ottawa, Canada, the aim of the Faculty of Canon Law is:


  Following the wishes of John Paul II in the Apostolic Constitution
  Sapientia Christiana of April 15, 1979, the Faculty of Canon Law cultivates and promotes the juridical disciplines in the light of
  the law of the Gospel. Instructs its students in these disciplines, so
  as to form researchers, university and seminary teachers, and others
  who will be trained to hold special ecclesiastical offices, such as
  chancery and tribunal positions, and
  to serve as advisers to bishops and religious communities.


Therefore those who obtain the Licentiate in Canon Law (JCL) degree, an ecclesiastical program governed by the Apostolic Constitution Sapientiae christiana and subsequent legislation and norms of the Holy See, may become researchers, university and seminary teachers, and others who will be trained to hold special ecclesiastical offices, such as chancery [the administrative office of a diocese or a department of the Curia Romana now having the responsibility for issuing bulls to establish new dioceses, benefices, etc.] and tribunal positions, and to serve as advisers to bishops and religious communities. And they are to practise their profession in the light of the law of the Gospel.
