I had a friend who found out that her boyfriend's parents hired a private investigator to check her out. That's the only case where I have personal knowledge.
One should at least check social media and public records these days. Professional background checks are probably only needed at the top 10 or 15% levels.
I've never heard of anybody doing a background check on a prospective spouse. Is this a thing? I'm asking in all seriousness.
Edward is right. (And yes, I know that Ploutos said he's reconsidering his position.) At an absolute minimum, any young man or young woman dating someone should be checking his/her social media and running a Google search.
Not every state makes court records easily available online, but Missouri does, and a young man or young woman in my state who isn't checking court records of someone during the dating process is making a huge mistake. Predators can be charming, but the probable cause statements filed along with criminal charges can pull the mask off that charm. Even if there aren't any serious criminal charges, it's probably important for a young man to know that his girlfriend has a lead foot that caused five speeding tickets, one of them for going 45 in a 25 mph zone. Same for legal problems due to unpaid credit cards, or a bad check case. Do you really want to find out two years after marriage that your wife declared bankruptcy to avoid paying bills she ran up during college? Or do you want to find out that your boyfriend got a driving-while-intoxicated case pleaded down to some lesser offense to avoid losing his license after a drunken party in college?
On pre-nuptial agreements, I think many of the people posting on this thread are thinking of a young couple, perhaps 18, 19, or 20, still living with their parents, or perhaps meeting in college, neither of them with significant assets, and neither with children from prior marriages or relationships. Like it or not, that's becoming less and less common as people get married later and later after finishing college -- and that's assuming the young man and young woman are both believers raised in godly homes. In dealing with adult converts, in today's American context, we can pretty much assume past moral problems and often that means child custody issues.
A more normal situation today, even in Christian circles, is two people dating and marrying in their late 20s or early 30s after establishing their careers. If one or both of the people in a couple moving from dating toward engagement have significant assets, or conversely, significant debt, they need to sit down and have a hard conversation, and that conversation may need to involve lawyers or financial professionals. If one of them has children, or is responsible for paying child support for children, lawyers need to be involved, even if it's just a matter of saying, "Please help us review the child custody paperwork and make sure we understand it." I have seen way, way, way too many people who didn't understand the details of their divorce decree until they found out the hard way what would happen following a remarriage. And that's in a "good" case of an uncontested divorce.
Things change radically with nasty divorces and custody fights. Imagine a woman whose elders have encouraged a biblical divorce of her as the innocent party due to a husband with multiple repeated affairs with multiple women, at least one of whom gave him a venereal disease that makes it physically dangerous for the victimized wife to be intimate with him. Now imagine that the wife went to court, obtained a large financial settlement, ownership of the marital home, and custody of their three children from a (now-ex) husband who is a very aggressive attorney who has made millions profiting off his legal competence, and decided to "pay off" his ex-wife with a sizeable settlement to prevent a divorce court from perhaps making him pay much more money.
If that woman doesn't get legal documents prepared prior to remarriage making clear who owns her home after marriage, and what happens to the special stock market investment fund she has established for her children's college education using the money from her ex-husband, she's likely making a huge mistake and risks serious legal consequences from her ex-husband.
Pre-nuptial agreements have a bad reputation for good reasons. However, sometimes they are the only legally enforceable way to protect one's children from an exploitive, abusive, or just generally irresponsible ex-husband or ex-wife in the event of death.
When a couple have significant assets or prior children being brought into marriage, consulting a Christian a lawyer and financial professional is prudent, and in some cases, absolutely essential.
I hope it's patently obvious that I'm not normalizing divorce. I take a harder line on that than most in the Reformed world.
What I'm saying is that because divorces do happen, and because we cannot trust the civil magistrate to protect the innocent party, even in a nasty divorce on biblical grounds, a legally binding contract can do what the civil magistrate should be doing, but refuses to do.
Practically speaking, I'm probably talking here mostly about couples with significant assets or debt, or who have children from a prior marriage. But in those cases, particularly with widows who have always been stay-at-home mothers and have no money, or older men whose wives have died and have children who they want to make sure inherit their assets, a pre-nuptial agreement can be a valuable tool to make sure that one's family is properly taken care of.
