create a marriage default swap, a sort of insurance against the marriage default.
Per Wikipedia, a credit default swap (CDS) is a credit derivative contract between two counterparties. CDS contracts have been compared with insurance, because the buyer pays a premium and, in return, receives a sum of money if one of the specified events occur. Here a financial institution sells MDS to any newly married couple for a premium. The buyer makes periodic payments to the seller, and in return receives a payoff if an underlying financial instrument defaults. Of course the seller has to make sure there will be no false divorce in order to collect the payout.
