I'm hoping somebody here knows this.
If you marry somebody who is in debt (lets say 20k or more), will their debt become yours? If they are ever unable to pay their bill, maybe because they can't find a job or lose their job, will the loan or credit card company be able to legally hold you responsible for paying it? I know they will harass whoever they can, but I'm wondering if you MUST pay your spouse's debt if they can't. Or what if your spouse dies? Are you legally obligated to assume payments?
Not really. . . here is how it will affect you.
If you marry someone who's in debt a lot and they can't pay their bill, their credit rating will go in the trash and they may be forced into bankruptcy.
That trashy credit rating will harm you as a couple if you try to take out a loan or a mortgage. Because with something like a loan or a mortgage they look at the couple's credit rating together and if one of them has a bad credit rating, it raises a red flag and they may reject you based on that. Although it may be possible you could attempt to get these things in your name entirely, that would also at the same time prevent you from submitting their income as part of your income.
And since morally speaking the money should be both of your money, then you will both have to work on paying the debt together.
Now if you divorce them, the debt shouldn't transfer and you shouldn't have to pay for it unless you re-finance.
It is worth noting that anything that is in their name alone they might be able to force a sale on in order to pay off as much of the debt if possible. Especially if the debt is unsecured.
Morally speaking I think you should look at their debt as your debt too. You combine a household you should combine money and look at the money as "our money". Therefore the debt is also "our debt". Things can change if they die or you divorce them, but this is certainly not something you want to plan for.
The main things I would be concerned about with the debt is the question of if it can be handled together and if the debt is an indicator of spending problems.
It depends quite a bit on what the debt is in too. I had quite a bit of debt when I got married. But it was all in student loan debts (still paying off those debts.) So it wasn't like I had a problem with going to the store with the credit card and raking up a bunch of debt that way. So I would certainly look at something like student loan debt different from credit card debt. Especially also since credit card debt has a massive interest rate while student loan debt interest is pretty low.
But when you are married and living as married you can't really separate yourself from the debt unless you intend to play some silly game where you each pay half of the living expenses and everyone has their own money and their own stuff. And at that point you are acting like roommates who have sex and not a married couple if you ask me. Because marriage is about a merging of two lives into one, not just living together.
