Most states allow spouses seeking a divorce to allege fault in the breakup of the marriage as a basis for the divorce. Alleging the other spouse’s fault—rather than seeking the divorce on no-fault grounds (irreconcilable differences or incompatibility, making the marriage unsustainable)—is generally a basis for requesting the court make an uneven distribution of the marital or community property in favor of the spouse alleging the other’s spouse’s fault.

In states that allow a spouse to seek a divorce on fault grounds, the grounds that may be alleged vary from state to state, but generally include adultery, cruelty, conviction of a felony, family or domestic violence, abandonment, mental illness, and substance abuse (drugs and alcohol). Spouses may also seek a divorce on no-fault grounds in these states.

In no-fault states, a spouse is not allowed to allege fault as grounds for the divorce, and the court is not allowed to consider fault in dividing the marital or community property—but allegations of fault may be considered for other purposes, such as spousal support and child custody. No-fault states include California, Colorado, Florida, Hawaii, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, Oregon, Washington, and Wisconsin. And in some states “incurable insanity” is a no-fault ground for divorce.

The grounds on which a spouse may seek a divorce (fault or no-fault) are usually located in a state’s statutes—often in the family code or domestic relations code.

In Virginia, spouses seeking a divorce can file on either fault or no-fault grounds. Fault grounds in Virginia include adultery, cruelty, desertion, and conviction of a felony with some period of imprisonment. No-fault divorce is also an option, typically after spouses have lived separately for a specific period, which is one year for most couples or six months if the couple has no minor children and has reached a property settlement agreement. When a divorce is filed on fault grounds, the court may consider the fault in the distribution of marital property. Virginia law allows for an uneven distribution of marital property in favor of the spouse who is not at fault. Additionally, fault may be considered when determining spousal support and child custody. It's important to note that while fault can influence the division of property and other divorce-related decisions, the specifics of each case can vary, and an attorney can provide guidance tailored to the individual circumstances.
