Just because you are married to someone does not give them the right to open a credit card in your name. This is still identity theft. Once you are married, it becomes all too easy for your partner to gain access to your personal information like your social security number and address. Since these credit cards are linked to your credit score, it could completely ruin you as an individual. If your partner does this, it is not okay. And if you suspect that it may be happening, check out CreditSesame. They will tell you how many accounts you have open, as well as your credit score.
Some couples choose to divvy out the bills to one another, instead of paying everything from a joint bank account. For example, the husband pays the electric while the wife pays for cable and Internet. An abusive partner will either threaten or make good on the act of not paying the bills. This is especially when they refuse to pay for head and electricity. Or, if they refuse to pay for credit cards, it means that your credit score will begin to go down.
