This paper deals with Legal Advice Bureau and Permanent Attorneys. The legal course of its establishment is explained from Dignitas connubia to MIDI. The first part of the paper explains what the Legal Advice Bureau and its purpose are. Furthermore, its pastoral and legal function is described, from conducting a pastoral investigation of discovering the canonical reason for the nullity of marriage to assisting believers who are in an "irregular situation." Also, the role of the permanent attorney has been explained and the legal regulation determining conditions for obtaining the mentioned service is clarified. A survey questionnaire regarding examples of the practice of church courts in Croatia was conducted. The results have shown that four of the five Courts of First Instance have implemented Article 113 of the DC in their case law, and Đakovo is currently working on its implementation. A total of ten permanent attorneys are present in the Courts of the First Instance in Croatia and the three of them are laypeople. A positive fact worth noting is that seven out of ten attorneys in question have a master's degree or a doctorate in canon law. Furthermore, it was established that in the Ecclesiastical Courts of the First Instance, in the period from 2016 to 2020, a total of 1357 marriages were declared null, and most lawsuits were conducted at the Court of Split. Regular Marriage Proceedings are still the most common way of dealing with marriage lawsuits, and the Short Marriage Proceedings before the Bishop, one of the novelties of the reform, has been conducted only four times in church court practice in Croatia. Informing the believers is an aspect of further research because it has been shown that believers come uninformed about their situation, but also about the marriage litigation process in general.
