On the other hand, I like the 50/50 split, which I would argue might be a better reflection of whose money the charity received that quaintly reflecting which spouse might happen to write the checks (or make the online gifts) for a couple.
The 50/50 split can also work quite well. My favorite information split the hard credit 50/50 and gave both spouses 100% soft credit, so when you looked at recognition, you didn't have to dance around adding hard and soft credit, you just looked at soft credit.
But, of course, assigning all the hard credit to the couple's bill-payer can also be made to work, if that's the way one has chosen to implement.
My US$0.02 worth; the usual disclaimers apply.
