When Party Misconduct Is Considered in a Missouri Divorce

Divorce is rarely just about dividing assets—it often involves complex emotional and personal issues. In Missouri, one question that frequently arises is whether a spouse’s behavior during the marriage can impact the outcome of the divorce.

The short answer: yes, but only in specific ways. Missouri courts may consider “marital misconduct,” but it doesn’t automatically control the outcome of your case.

Missouri Is a “No-Fault” Divorce State—But That’s Not the Whole Story

Missouri is considered a no-fault divorce state, meaning you do not have to prove wrongdoing (like adultery or abuse) to get divorced. Instead, the court focuses on whether the marriage is “irretrievably broken.”

However, that doesn’t mean misconduct is ignored entirely. Certain behaviors can still play a role—especially when it comes to financial and fairness considerations.

What Counts as Marital Misconduct?

“Marital misconduct” generally refers to behavior by one spouse that negatively impacts the marriage or the other spouse.
Common examples include:
  • Adultery 
  • Financial irresponsibility or hidden spending 
  • Dissipation of marital assets (wasting money) 
  • Substance abuse 
  • Domestic violence or abuse 
  • Abandonment 
Not all bad behavior will affect the case—courts are primarily concerned with misconduct that has a real impact on finances or fairness.

How Misconduct Affects Property Division

Missouri courts divide marital property based on what is fair and equitable, not necessarily equal. One of the factors judges may consider is the conduct of the parties during the marriage.
This means misconduct can matter when:
  • One spouse wastes marital funds (for example, spending large amounts on an affair or gambling) 
  • Assets are hidden, transferred, or misused 
  • One party’s behavior significantly impacts the financial situation of the marriage 
In these cases, a judge may award a larger share of assets to the other spouse to balance things out.

Misconduct and Spousal Maintenance (Alimony)

Missouri courts divide marital property based on what is fair and equitable, not necessarily equal. One of the factors judges may consider is the conduct of the parties during the marriage.
This means misconduct can matter when:
  • One spouse wastes marital funds (for example, spending large amounts on an affair or gambling) 
  • Assets are hidden, transferred, or misused 
  • One party’s behavior significantly impacts the financial situation of the marriage 
In these cases, a judge may award a larger share of assets to the other spouse to balance things out.

Misconduct and Child Custody

When children are involved, Missouri courts prioritize the best interests of the child.

Misconduct becomes highly relevant if it impacts parenting ability or the child’s well-being, such as:
  • Substance abuse issues 
  • Domestic violence 
  • Neglect or unsafe living conditions 
In these situations, the court may limit custody or visitation to protect the child.

What Misconduct Usually Does NOT Affect

It’s important to be realistic about what misconduct can and cannot do in a Missouri divorce.

Generally, courts do not:
  • “Punish” a spouse simply for bad behavior 
  • Award everything to one party because of infidelity alone 
  • Focus on personal grievances that don’t impact finances or children 
The court’s goal is fairness—not retribution.

Proving Misconduct Matters

If you believe misconduct should be considered in your case, evidence is critical. This might include:
  • Financial records showing unusual or excessive spending 
  • Communications or documentation of behavior 
  • Witness testimony 
  • Police reports or court records (in serious cases) 
Without solid evidence, claims of misconduct may carry little weight.

Why Legal Guidance Is Essential

Determining whether misconduct is relevant—and how to use it effectively—requires careful legal strategy.
An experienced Missouri divorce attorney can:
  • Evaluate whether misconduct applies in your situation 
  • Gather and present evidence properly 
  • Protect you from unfounded allegations 
  • Ensure your case focuses on what actually matters to the court 
Approaching these issues the right way can significantly impact the outcome of your divorce.
