In the context of family law, divorce proceedings are categorized by the requirements needed to legally dissolve a marriage. The primary difference between fault-based and no-fault divorce lies in whether one party must prove specific misconduct by the other to obtain a decree.1

Fault-Based Divorce

Fault-based divorce requires the petitioner to demonstrate that the marriage has failed due to specific actions or behaviors by the other spouse. Historically, these grounds have included:
* Adultery
* Desertion
* Cruelty
* Alcoholism
* Imprisonment1

No-Fault Divorce

In contrast, no-fault divorce does not require proof of specific wrongdoing. Instead, it is granted based on the premise that the marriage has reached an end due to factors such as:
* Incompatibility
* Irreconcilable differences
* Irretrievable breakdown of the marriage1

While fault-based systems focus on assigning responsibility for the marital failure, no-fault systems prioritize the reality that the relationship has ceased to function, allowing for dissolution without the need to litigate specific grievances.1
