Details of changes to a system that critics including Francis himself had attacked as needlessly bureaucratic, expensive and unfair were unveiled today with the publication of a papal letter on the issue to Catholic churches across the world.
In it, the Argentinian pontiff says annulments will henceforth require only one decision rather than having to be approved by two church tribunals, as currently.
A streamlined procedure is to be introduced with most cases to be handled by individual bishops rather than subject to a hearings process.
The Pope's letter follows a year-long review by experts in canon, or religious, law. It also asks bishops conferences to ensure there are no costs involved in the process of securing an annulment.

While Francis is seeking to democratise the procedure in a way that would appear to make an increase in the number of annulments likely, his letter does not amend the exceptional conditions under which they can be granted.
In his letter, he strongly reaffirms the principle of the indissolubility of marriage while highlighting the "enormous number of believers" for whom annulment is currently not an option for various reasons.
Church doctrine allows for unions to be cancelled -- effectively declared to have never existed -- when the marriage is judged to have been fundamentally flawed from the outset.
Possible justifications for reaching this conclusion include non-consummation of the marriage, one or both partners having entered into it without the intention of staying in the relationship, or one of the partners having no desire to have children.
Alcohol and drug dependency can also be taken into consideration.
