When you get married, your credit score remains personal and separate from your spouse's credit rating. The two credit scores do not merge into a single score. However, it's worth noting that lenders may consider your joint income when evaluating your loan application, which could make it easier for you to obtain a loan.
If you get married in community of property, your credit rating will be affected. In this type of marriage, both spouses are jointly and severally liable for any debt incurred by either party, regardless of whether it was incurred before or after the marriage.
This means that each spouse is 100% responsible for the other's debts. Creditors can pursue either spouse or both until the debt is fully paid off. If one spouse doesn't have enough money or assets to cover the debt, the other spouse is responsible for making up the difference.
Creditors may also target the wealthier spouse's income or assets to recover the debt. Unfortunately, this is the law if you choose to get married in community of property. It's important to be aware of these potential consequences before making a decision about the type of marriage contract you want to enter into.
