I can make 101 assumptions, but I expect it is not that uncommon for Catholics to make the mistakes and get remarried outside the church without an annulment (so we have 3 issues, defying the church, adultery, and scandal).
I suspect it is also not all that uncommon to realize the mistake and try to correct it (start the process to attempt to attain the annulment, and live a chaste life together (separation would probably make the rest of this question mute)).
At that point the potential scandal still remains (annulment is not yet attained and marriage is not yet blessed). Should the couple still be barred from confession and absolution? Allowed absolution but be barred from communion due to the perception of scandal? Or not even barred when the perception of scandal is not present (ie in a different Parrish).
Is opinion shopping an abuse of the sacrament :rolleyes:… (if the opinions given here differ to the opinion of the local confessor, should the couple find a different confessor - or accept the original’s judgment).
