No-fault divorce is a type of divorce where neither party is required to prove wrongdoing or fault to end the marriage. In a no-fault divorce, the parties can simply state "irreconcilable differences" as the reason for the divorce. It aims to reduce animosity and bitterness by eliminating the need to publicly air grievances in court. On the other hand, fault-based divorce requires one spouse to prove specific acts of misconduct, such as adultery, abuse, or abandonment, which caused the breakdown of the marriage. Fault-based divorces can be more contentious, time-consuming, and expensive than no-fault divorces.
