You and your spouse have always used a joint credit card, and you did not have one at all before you got married. Now you have decided to get divorced, and so you're canceling that joint account. Perhaps you already canceled it as soon as you filed to prevent any confusion.
At the same time, you fully expect your spouse to end up paying you alimony every month. Maybe you've already talked about it. Maybe not. Perhaps you gave up your own career years ago, allowing your spouse to pursue theirs, and so you know you deserve some support as you exit the relationship.
Your question, then, is whether or not you can use that alimony payment as income when you put in an application for a new card.
You'll be glad to know that you can. You don't have to; there's no obligation to tell the credit card company that you have that income. But it does count as income, and listing more sources can make you more likely to get the card when all is said and done.
Plus, at least in the beginning, alimony may be your only income. Using it on the application allows you to get a credit card right away, as you look for a new job or start a new career. This gives you some financial options and allows you to build your credit when you use it responsibly.
Alimony is one of the more contentious issues in many divorce cases. Make sure you know exactly what legal options you have and what your rights are.
