I don't really know, but I wouldn't think so. I mean, marriage settlements were essentially a contract between two people (or between one person and the other's guardian/representative), and everything in the contract is conditional on the marriage taking place. When two people sign a contract together and then one person dies, the contract is nullified. (Even the Bible talks about this.) Therefore it seems to me that the death of the other party in the contract would render the marriage settlement void.
But I haven't done any research on it so I might be wrong.
