Fault generally falls under one of the following categories: abandonment/turning out, adultery, cruel or barbarous treatment, indignities, or alcohol/drug abuse. Some of these may involve further legal action in addition to the separation. For example, in the case of domestic violence (cruel or barbarous treatment), you may need to file a specific domestic violence action and obtain a restraining order for your own protection. Those at risk of being a victim of domestic violence should get this court order at once.
