## Introduction

A fault divorce is a traditional form of divorce where the filing spouse must prove the other spouse’s wrongful conduct caused the breakdown of the marriage. Typical grounds include adultery, cruelty (physical or emotional abuse), desertion or abandonment, imprisonment, substance abuse, and severe mental illness.

While every state now permits some form of no-fault divorce, many still allow fault-based filings. People choose a fault divorce for several reasons: some states have shorter waiting periods when fault is proven, alleged misconduct may affect alimony or attorney’s fees, and in limited situations it can influence property division or custody outcomes. Because the rules vary by state, it’s smart to confirm your state’s requirements before filing.

This guide explains the core concepts, the legal process, and how fault findings can affect money, parenting, and timelines—so you can plan your next steps with clear expectations.

## Core Concepts

### Recognized Fault Grounds

States use different terms, but these grounds are widely recognized:

- Adultery
  - Proof often includes messages, photos, hotel or travel records, spending patterns, witness testimony, or private investigator reports.
  - Some states require corroboration beyond one spouse’s testimony.

- Cruelty (physical or emotional)
  - Includes violence, threats, harassment, stalking, or severe emotional abuse.
  - Proof may include medical records, police reports, protective orders, photos, and texts or emails.

- Desertion or Abandonment
  - One spouse leaves the marital home and remains apart for a set period (often 1+ year), without consent or a valid reason, and with no intent to return.
  - Proof includes lease or utility records, witness testimony, and communications showing no intent to reconcile.

- Imprisonment
  - A spouse is convicted and incarcerated for a significant term (the length varies by state).
  - Proof includes court records and sentencing documents.

- Substance Abuse
  - Ongoing drug or alcohol abuse that disrupts the marriage or endangers the family.
  - Proof includes rehab or medical records (where obtainable), police reports (DUIs), financial records, and testimony.

- Incurable Mental Illness
  - Severe mental illness that makes cohabitation unsafe or untenable, sometimes requiring expert evaluation and a statutory period of separation or hospitalization.
  - Proof typically involves medical or expert testimony; rules vary significantly by state.

State statutes control which grounds are available and the proof required. Always verify the exact elements in your jurisdiction.

### Proof and Procedure

- Burden of Proof
  - The filing spouse (petitioner) must prove the ground. The standard is usually “preponderance of the evidence” (more likely than not). Some states ask for stronger proof for adultery.

- Evidence Rules
  - Lawful, admissible evidence wins cases. Do not break privacy or wiretap laws, hack accounts, or install spyware. Illegally obtained evidence can be excluded and can create criminal or civil risk.

- Discovery
  - Each side can request text messages, emails, financial records, social media posts, medical and employment records (with limits), and depose witnesses.

- Temporary Orders
  - Courts can enter temporary orders for support, custody, parenting time, use of the home, or protection while the case is pending.

- Settlement vs Trial
  - Many cases settle after discovery. Settlement can address property, support, and custody regardless of fault. If no settlement is reached, the judge decides at trial.

### Defenses and Counterarguments

Respondents can contest the alleged ground and raise legal defenses:

- Condonation: The filing spouse forgave the conduct (often shown by resuming marital relations) and continued the marriage afterward.
- Recrimination: Both spouses committed similar misconduct.
- Connivance/Collusion: The filing spouse encouraged or staged the misconduct.
- Provocation: The filing spouse provoked the behavior.
- Insufficient Proof: The evidence does not meet the legal standard or lacks required corroboration.
- Statute-Based Limits: Missed deadlines or statutory separation rules were not met.
- Counterclaim: Respondent may file a competing no-fault or fault ground.

These defenses can reduce or eliminate fault findings and affect outcomes on money and parenting issues.

## Key Examples or Case Studies

The following illustrations are based on common court outcomes. Local laws control actual results.

- Smith v. Smith (adultery)
  - Facts: Mrs. Smith presented messages, hotel receipts, and credible testimony showing an ongoing affair.
  - Result: Divorce granted on adultery. Mrs. Smith received a larger share of assets because the judge found the affair caused marital funds to be spent on the relationship (financial dissipation).
  - Lesson: Judges focus on credible, corroborated proof and whether the misconduct had financial effects.

- Jones v. Jones (desertion)
  - Facts: Mr. Jones showed his spouse moved out without agreement and stayed away more than a year. He offered emails showing no intent to return and testimony from neighbors.
  - Result: Divorce granted on desertion. Mr. Jones received primary custody based on stability and the children’s best interests.
  - Lesson: For desertion, courts look for continuous absence without consent or valid cause, plus a clear intent not to return.

## Practical Applications

- Deciding Between Fault and No-Fault
  - Consider filing both if your state allows. A no-fault claim can resolve the marriage even if fault is not proven, while a fault claim may affect support or waiting periods.
  - Weigh costs and benefits. Proving fault can take more time, add legal fees, and raise conflict.

- Step-by-Step Process
  1. Consult an attorney to review your state’s grounds and timelines.
  2. Safety plan if abuse is present; consider protective orders.
  3. Gather evidence early (lawfully). Preserve texts, emails, photos, bank and credit card statements, call logs, social media, and witness names.
  4. File the petition stating fault grounds and any alternative no-fault ground, plus requests for temporary orders.
  5. Serve the respondent properly under state rules.
  6. Attend temporary hearings for support, custody, and parenting time.
  7. Exchange discovery, take depositions, and file motions to exclude improper evidence.
  8. Attempt settlement through negotiation or mediation.
  9. Prepare for trial with organized exhibits and witness outlines if no settlement is reached.
  10. Obtain the final decree addressing divorce, property division, alimony, custody, and child support.

- Evidence Tips
  - Keep originals and make secure copies. Maintain a timeline of events.
  - Do not guess passwords or install tracking software on devices you do not own or share with consent.
  - Be careful on social media; assume posts will be seen in court.
  - Consider a forensic accountant if financial dissipation is suspected.

- Effects on Money and Parenting
  - Property Division: In equitable distribution states, fault rarely changes the split unless it has an economic impact (e.g., spending marital funds on an affair). In community property states, fault generally does not change the 50/50 presumption, but waste can be accounted for.
  - Alimony: Many states consider marital misconduct when deciding eligibility, amount, or duration. For example, adultery or abuse can increase or bar alimony depending on the state and who committed the conduct.
  - Child Custody: Custody turns on the child’s best interests. Abuse, addiction, or criminal behavior can influence parenting time, supervision, and decision-making authority.

- Cost and Timeline
  - Fault cases often take longer due to discovery and contested hearings.
  - Expect added costs for investigators, expert witnesses, transcripts, and multiple court appearances.

- Common Pitfalls
  - Relying on hearsay without corroboration.
  - Destroying or hiding evidence (spoliation).
  - Illegal recording or tracking that backfires in court.
  - Ignoring temporary orders or using children as messengers.

## Summary Checklist

- Confirm your state’s available fault grounds and proof rules.
- Decide whether to plead both fault and no-fault.
- Prioritize safety if abuse is present; seek temporary protection when needed.
- Gather lawful, admissible evidence and keep a detailed timeline.
- Anticipate defenses like condonation or insufficient proof.
- Consider financial dissipation and collect supporting records.
- Be realistic about costs, time, and impact on children.
- Use settlement where appropriate; prepare thoroughly if trial is necessary.
- Follow all temporary orders and keep communications civil, especially about the children.
