Fault Based Divorce.

Fault-based divorce refers to a type of divorce where one party alleges that the other party is responsible for the breakdown of the marriage due to specific reasons or "faults." In fault-based divorce systems, the filing party must provide evidence or proof that the other spouse engaged in certain behaviors that led to the marriage's dissolution.

The specific grounds for fault-based divorce can vary depending on the jurisdiction, but common reasons may include:

1. Adultery: When one spouse engages in extramarital affairs or sexual relationships outside the marriage.
2. 
   
3. Cruelty or physical abuse: When one spouse subjects the other to physical harm or emotional cruelty.
4. 
   
5. Desertion or abandonment: When one spouse leaves the marriage without justification or consent.
6. 
   
7. Substance abuse: When one spouse has a severe drug or alcohol addiction that significantly affects the marriage.
8. 
   
9. Imprisonment: When one spouse is incarcerated for a certain period, typically a felony conviction.
10. 
    
11. Mental illness or insanity: When one spouse is suffering from a severe mental illness or is declared legally insane.

It's important to note that fault-based divorce systems are becoming less common in many jurisdictions. In recent years, many countries and states have shifted toward "no-fault" divorce systems, where neither party is required to prove fault or assign blame for the breakdown of the marriage. No-fault divorce allows couples to seek a divorce without having to demonstrate specific reasons or faults. Instead, they can simply state that the marriage is irretrievably broken or has irreconcilable differences.

No-fault divorce is generally considered to be more efficient, less adversarial, and less emotionally stressful than fault-based divorce, as it promotes a less confrontational approach to the dissolution of a marriage
