The rise in popularity of pre-nuptial agreements and post nuptial agreements, is understandable for the level of insurance and certainty it can give couples about to marry or during marriage.

Having a contract drafted dealing with behaviour to deal with reconciliation situations is a much newer and more unusual concept.  

The financial issues can be dealt with in a post nuptial agreement, which if properly drafted can provide reassurance for couples worried about future separation or divorce.  This document can confirm how assets will be divided and what financial support there will (or won't be).  Taking this further to also prepare a document including promised changes in behaviour is something some people may find difficult to agree and accept.
