The problem does not arise in such cases as yours, but in marriages of many years, many children, and much parish involvements. (CFM, CCD etc)

Marriage is not defined by longevity or offspring. I don't wake up everyday and wonder, "Gee, it's been eight years. Am I married yet?" Marriage either occurs, or doesn't, when the vows are made between spouses. They are the dispensors of their own sacrament. The priest is a witness and provides the blessing of the Church, but he does not administer the sacrament.

You could have 18 kids and be share wedding rings with someone for decades and not be legitimately married in the first place. If it's determined that the vows were valid, no amount of "irrenconcilable differences" afterwards can in-validate those vows.

18 kids after a church wedding and no apparent problems, parish activity, and general happiness over a number of years is a pretty good indication of a good marriage. On what grounds is anyone going to declare this marriage invalid. And if they did - would it be understandable if people concluded “Money talks”. The end of such a marriage requires a divorce not an annulment. Be honest.
