Go back to sleep. Your comment is pure fantasy. In reality, the beis din side of gittin is ugly. No one goes to BD to settle matters amicably. They go to fight. The only question is how vicious the battles are. Instead of expressing these nice ideals, speak to people who have hashed matters out in BD. Ask toanim how’s business. The reality is alarmingly different. When the OP inquires about how to prevent divorce, it is a serious question. How does one avoid or prevent a personal holocaust. I do not use these words lightly.
In reality, men withhold gittin and women withhold children. Each one uses their best weapon. But it is war. The false accusations of infidelity, domestic violence, child abuse, etc. are everyday occurrences. There are prevailing myths that these are mostly men committing these atrocities. In reality, the responsibility is balanced at close to 50-50. There are about as many evil men withholding gittin and support as there are evil women not allowing children to see their father, or having him arrested for crimes that were never committed.
There are mediators in the frum community who are passionate about resolving the matters in dispute to enable the couple to proceed peacefully to a beis din. Their failure rate is high, as one or both sides is bloodthirsty and will simply not compromise on anything. Those couples that succeed in resolving matters amicably (yes, there are plenty) rarely use professional mediators. These mediation experts have experience and are good, well meaning people. The fault lies with the pained individuals, whose love has turned to hate, and are bent on revenge and causing as much trouble for the other.
Beis Din has a mammoth task, to force the two sides to accept a psak, and comply with it. Even after a psak is given, compliance is a serious problem, and this often involves the only recourse, one which is universally dreaded – going to secular court.
