With great respect to Mr. Tripathi,
The idea is not practical. The insurance companies enter the area where there is profit. In this particular area, there is no profit. The insurance companies practice only in an area where there is risk element and the incidents happen beyond our control. Whatever precautions one may take, there is a scope of eventuality, which may attract insurance payment. Take the case of either road accidents, fire accidents, floods, crop disaster or draught. In all of these things, in normal conditions (there are exceptions), human involvement is not there so that to create such an eventuality where one can claim.
As the completely irretrivable break-down of marriage is nothing that husband and wife do not adjust themselves. Such is the situation in the case of divorce on the ground of cruelty or desertion. The cunniving couple can insure their marriage for a huge sum and after one year or two years on any ground seek divorce and can claim insurance. The common human being has not raised to such high ethical and moral level, only in genuine cases, they seek insurance claim. The insurance inspectors also cannot refuse the claim as cunniving couple come with water tight schemes to milch the insurance claim.
