Strong marriages don’t succeed by luck -- they succeed by design. Leading family lawyer and Leach Legal founder Catherine Leach shares the patterns she’s seen over 35 years that determine whether a relationship thrives or falls apart. Recognised nationally for her strategic approach to family law, she has guided thousands of couples through complex transitions and brings a rare blend of empathy, clarity and realism to the topic. 

Beyond her legal practice, Catherine has held senior governance roles with the Entrepreneurs’ Organisation in Asia-Pacific, co-founded the Family Law Association of Victoria, and mentors entrepreneurs navigating both business and family pressures. She reveals the real reasons marriages fail, why some endure, and what entrepreneurs must understand to protect both their relationships and their wealth. 

Takeaways 
Strong marriages thrive on steady communication, mutual respect and choosing the right battles. 
Small unresolved grievances compound over years and quietly erode even stable relationships. 
Entrepreneurs often struggle because obsessive work patterns push family connection aside. 
Financial imbalance fuels mistrust when one partner avoids or fears understanding the numbers. 
Strategic divorces start with transparency, calm process and resisting emotional escalation traps. 
Long-term relationship success requires deliberate planning, shared vision and consistent everyday effort.
