Do both Godparents/Sponsors have to fulfill all the requirements?

What if one of the godparents is confirmed and the other is not, but both are Catholic? For instance, what if one potential godparent is confirmed, has taken all of the sacraments so far required, and so on, but the other has only been baptized and is mildly handicapped? According to Catholic Canon Law, can they still both serve as godparents?
