Your points are moot. The bishop and Canon Law apply to Catholics. It does not matter what civil law says, Catholic are bound to Church law.
As for most Catholics not knowing that the Bishop can approve a civil divorce in certain limited circumstances is true. Hopefully, this discussion will inform them.
Brother, you are going off on a tangent that is essentially irrelevant to the issue at hand - which has to do with the civil law. Excuse me, I am 71, brought up on the
Baltimore Catechism, have attended college seminary, and just happen to have a JD and have practiced law. And I have had over 20 years of teaching in RCIA in a parish where we follow the Magisterium. It is just possible I know a bit more than you are willing to give me credit.
You may talk till the cows come home about Canon law; I will stand on my statement.
This is not a matter of Canon law; it is a matter of civil law - and I will reiterate: a couple may go through a divorce for the purpose of dealing with civil law rules concerning property, and have no intent of remarriage to others (as they recognize Church law and Christ’s admonishment concerning divorce), nor are they approaching the civil divorce court because of hatred, or ennui with the marital state or any of the multiple other reasons that most people approach divorce. They in fact may deeply love one another; but faced with overwhelming medical bills and fully aware that one of them is in terminal stage of cancer, they seek to wend their way economically through whatever safeguards they may have to deal with the financial crisis they are facing.
The case posited is not of a couple with seemingly unlimited resources financially; but rather with limited resources, and are attempting to put the surviving spouse in a reasonably stable financial position after the other party dies of the cancer.
And it is not the surviving spouse who may be seeking to “abandon” the terminal spouse; it can be the husband, with terminal cancer, seeking to assure the soon-to-be-widow that she will not be reduced to poverty - as in having lost the house, retirement benefits, and any other assets she might have had, if the husband had simply keeled over with a heart attack instead of the devastation which treatments for cancer cause financially.
In short, I do not suggest that Canon law be violated. I do suggest that for whatever reason compels people to divorce court, the vast majority of them have no clue that the bishop might want to be involved in the decision, or at least have someone at his direction involved in it. In the OP’s question, this is about civil, not Canon law; it is about finances, not about sacrament.
As noted, Medicaid looks for matters of fraud. If the couple goes through a divorce and proceeds to live openly as husband and wife in the same household, or (as is often the case) they live in separate households in a retirement community but spend basically 24/7/365 together, they may have fraud issues to deal with. But I doubt that Medicaid investigators are going to consider attending the same Mass as fraud; or eating communal meals at the retirement center as fraud. Keeping separate apartments/condos and living together in one likely would bring fraud charges.
I would hope this will make my position clear; I don’t expect you to have ESP; but I do presume you can separate out questions which have to do with what the State expects, which may be quite different from what the Church expects.
And I would point out that in some European countries, a couple may have two wedding ceremonies; one at the parish, and one at the government office, as certain countries approach marriage a bit differently that we generally do in the US. They likely would understand that while civil law and Canon law may be generally moving in the same general direction, they each have different paths and laws and purposes.
