Hello Phemie.
Sorry, but it takes more than a simple session with the Parish Priest to obtain a dispensation. Dispensations aren’t given lightly and I’ve heard sad tales of those who needed them not even being told they needed one and being allowed to marry in the Church building, but finding out later there is a mess others made for them of their marriage. It is a Sacrament. Treating as lightly as you suggest does grave harm not only to the couple, but to the Church. If a simple one question session is all you think should be done for the couple in an irregular marriage situation, then you shouldn’t try to help anyone marry in the Church. Sorry if that offends, but bad advise taken does hurt those to whom it is given. And I’ve a dear friend who went through with a marriage that was passed off as nothing and later they found out there was much more to what should have been given them from the start. They had a mess to clean up that someone made for them.
