Sunday Mail (Qld) 17 August 2008: A new trend emerging has couples signing pre-nuptial agreements to protect their assets and establish rules about lifestyles. One in three marriages are ending in divorce, so couples are becoming more realistic about their relationship prospects. Some of the rules being drawn up in the pre-nups include domestic duties, social activities and punishments for infidelity. Some couples are also defining what they believe amounts to infidelity within a relationship. Traditionally pre-nups had been taken out by celebrities or the very wealthy, but now many couples are starting to get their 'rules' outlined in detailed and binding legal agreements.
