Their is however an in between point were you can ask to be removed as an active member of that church. perhaps for some of reasons below...so it looks like this has been done and has been passed as long ago as 2006
One does not even have to ask to be removed from the Catholic Church: one can merely be schismatic, apostate or heretical. It pre-dates 2006 and there are various non-Catholic communities of faith which currently exist and attest to earlier acts of separation from the Catholic Church. So, the concept of the movement for debaptism is nothing new.
The Pontifical Council on
Actus Formalis Defectionis Ab Ecclesia Catholica (Formal Act of Defections from the Catholic Church):
1. For the abandonment of the Catholic Church to be validly configured as a true actus formalis defectionis ab Ecclesia so that the exceptions foreseen in the previously mentioned canons would apply, it is necessary that there concretely be:
a) the internal decision to leave the Catholic Church;
b) the realization and external manifestation of that decision; and
c) the reception of that decision by the competent ecclesiastical authority.
2. The substance of the act of the will must be the rupture of those bonds of communion – faith, sacraments, and pastoral governance – that permit the Faithful to receive the life of grace within the Church. This means that the formal act of defection must have more than a juridical-administrative character (the removal of one’s name from a Church membership registry maintained by the government in order to produce certain civil consequences), but be configured as a true separation from the constitutive elements of the life of the Church: it supposes, therefore, an act of apostasy, heresy or schism.
3. The juridical-administrative act of abandoning the Church does not per se constitute a formal act of defection as understood in the Code, given that there could still be the will to remain in the communion of the faith.
On the other hand, heresy (whether formal or material), schism and apostasy do not in themselves constitute a formal act of defection if they are not externally concretized and manifested to the ecclesiastical authority in the required manner.
4. The defection must be a valid juridical act, placed by a person who is canonically capable and in conformity with the canonical norms that regulate such matters (cfr. cann.124-126). Such an act must be taken personally, consciously and freely.
5. It is required, moreover, that the act be manifested by the interested party in written form, before the competent authority of the Catholic Church: the Ordinary or proper pastor, who is uniquely qualified to make the judgment concerning the existence or non-existence of the act of the will as described above in n. 2.
Consequently, only the convergence of the two elements – the theological content of the interior act and its manifestation in the manner defined above – constitutes the actus formalis defectionis ab Ecclesia catholica, with the corresponding canonical penalties (cfr. can. 1364, § 1).
6. In such cases, the competent ecclesiastical authority mentioned above is to provide that this act be noted in the baptismal registry (cfr. can. 535, § 2) with explicit mention of the occurrence of a “defectio ab Ecclesia catholica actu formali”.
7. It remains clear, in any event, that the sacramental bond of belonging to the Body of Christ that is the Church, conferred by the baptismal character, is an ontological and permanent bond which is not lost by reason of any act or fact of defection. In respect of Clause 7. As much as the Catholic Church would extend to assist with Pontifical guidelines, even with severance from it by members of its congregation (by benefit of the doctrine on Free Will), there are dogmas which the Catholic Church has no authority to undo. The theological argument on baptism has been discussed in a related topic in the past.
