North, the answer to your question I guess depends on whether you are filing a joint return. From Publication 550 in the section about capital losses:

Joint and separate returns. If you and your spouse once filed separate returns and are now filing a joint return, combine your separate capital loss carryovers. However, if you and your spouse once filed a joint return and are now filing separate returns, any capital loss carryover from the joint return can be deducted only on the return of the spouse who actually had the loss.
