Who says British etiquette experts Debrett's don't move with the times?
The chroniclers of the cream of British society since the late 1700s have put together a book on how to behave during a divorce.
The idea is to assist emotionally distraught couples in maintaining decorum in the midst of their battles over custody and cash.
Debrett's has teamed up with divorce lawyers Mishcon de Reya, who represented the late Princess Diana, for the publication.
The Debrett's Guide to Civilised Separation provides tips on how to break the news to friends and colleagues and information on the process of divorce.
