Is a prenuptial agreement permitted for a Catholic marriage?

A prenuptial agreement typically outlines what happens in the event a marriage ends in divorce or some other dissolution of the marriage. This at first appears to be at odds with the idea of a Catholic marriage being two people vowing to be married "till death do us part" (i.e. they are still married even if they are civilly divorced). Is a prenuptial agreement permitted for a Catholic marriage? I'm particularly wondering if a prenuptial agreement would be used as grounds for annulment, since it might suggest that they weren't serious about their marriage vows.
