You each have individual credit histories, reports, and scores. There is no such thing as a combined report for a couple, even if you hold some credit jointly.
When you go for a mortgage, the lender will pull all three of your individual scores, so six in all, look at each of your middle scores, and generally go with the lower score. So if you will need both incomes to qualify, it's very important that you each get your credit as good as possible.
* Credit is a wonderful servant, but a terrible master. * Who's the boss --you or your credit?
