Michigan Adultery Law in the Criminal Code
Adultery, often viewed as one of the most devastating betrayals within a marriage, frequently results in the dissolution of the marriage relationship. While the emotional ramifications on the other spouse are universally acknowledged, many are unaware that engaging in adultery is a criminal offense under Michigan Law.
Michigan Law classifies adultery within marriage as a felony. Under Michigan adultery law, those guilty of adultery while married could face severe consequences, including up to five years of imprisonment. Interestingly, the felony status of adultery also extends to individuals who are not married but knowingly engage in such acts with someone legally wed.
Although some may consider this law antiquated, the fact remains that in Michigan, the pain of infidelity can extend far beyond personal relationships and into the world of criminal liability. Talk to a Michigan divorce attorney today to discuss how adultery can affect your divorce case.
Penalties Provided Under Michigan Adultery Law
In Michigan, adultery is a felony offense with potentially severe legal consequences. According to Michigan Adultery Law MCL 750.31, a prosecution for adultery may only be initiated by the aggrieved spouse within a year of the act’s occurrence. If found guilty, the adulterer may face imprisonment of up to five years, a fine of up to $5,000, or both.
Despite the severity of these penalties, the likelihood of an individual being charged with adultery in Michigan is virtually non-existent in contemporary times. In fact, no known cases have been brought forward by prosecutors in any Michigan court over the last century.
Thus, while the law remains in effect, its practical application has faded from the state’s legal landscape, rendering the risk of actual prosecution for adultery highly improbable.

Uncovering the Impact of Adultery and Michigan Divorce Law
Under Michigan Law, no-fault divorce prevails, meaning that regardless of the reasons behind the dissolution of a marriage, accusations of misconduct such as adultery cannot be included in the divorce process.
Michigan as a No-Fault Divorce State
Michigan is a no-fault divorce state. As such, the court is not interested in hearing claims of misconduct when deciding whether to grant a divorce. A party only needs to assert a breakdown in the marital relationship such that the object of matrimony has been destroyed for purposes of a Michigan divorce.
How Adultery Affects the Divorce Process
It is essential to understand that being a no-fault state does not imply adultery is entirely disregarded in divorce. Adultery affects the marital estate in many ways. Indeed, infidelity can still impact various aspects of the divorce case, such as the division of assets, spousal and child support amount, and child custody.
Consequently, although the act of adultery is not directly addressed in the divorce complaint, it is crucial to be aware of its potential repercussions and to seek professional legal advice. Michigan family lawyers can ensure a fair outcome for you and your family.
While it is relatively straightforward to measure the impact of issues such as alcoholism or gambling addiction, quantifying the monetary implications of adultery can be more complex. Family law judges consider adultery as it relates to marital spending and its impact on minor children.
Successfully proving that the unfaithful spouse dissipated marital assets, which is marital property that otherwise would have been accessible to both parties, may prompt the court to allocate a more significant portion of these assets to the affected spouse. This approach allows for a more equitable resolution in many marriages in light of the challenging task of ascribing a financial value to instances of adultery.
Adultery and Fault in Property Division
Navigating the complex landscape of property division during a divorce can be daunting, especially when infidelity or other forms of misconduct are involved.
In these cases, the court’s consideration of adultery affects the parties’ past conduct and future performance and substantially impacts the outcome of property division in a divorce. While adultery may not single-handedly determine the division of assets and debts, it is undeniably a contributing factor weighed alongside other relevant aspects.
Acknowledging the reasonable likelihood that a Michigan family court or judge’s decision will strive to maintain fairness is crucial. By proving fault, the balance of property awards may tilt in favor of the non-cheating spouse, providing a sense of compensation and justice in the face of betrayal.
Infidelity as a Spousal Support Component: Exploring its Relevance and Impact
Michigan’s adultery laws mean that even though fault is no longer legal grounds for divorce, family law in the state still takes infidelity into consideration when determining spousal support. If one spouse is found to have engaged in extramarital affairs, a court can factor this into the alimony order, either reducing the alimony amount provided to the offending spouse or negating it altogether.
Judges in Michigan consider both parties’ past behavior and current situation when deciding if alimony should be awarded. This includes how much impact the affair has had on each partner financially and their lifestyle before they choose to separate. As such, adultery can significantly affect the award of alimony and spousal and child support due in a divorce proceeding.
Adultery and Its Affect on Child Custody Disputes
In the complex world of child custody disputes, judges often face the challenging task of assessing the moral fitness of each parent in order to make a well-informed decision deciding a custody case that prioritizes the children’s best interests.
While affairs and infidelity can undoubtedly cast a negative light on a person’s character and ethical decision-making, it is crucial for family attorneys to carefully evaluate whether these actions directly impact the individual’s ability to be a nurturing and responsible parent.
In many cases, the effects of an affair may not necessarily translate into poor parenting—consequently, it is essential for legal teams to delve deeper into the specific circumstances of the present situation and weigh the actual consequences of a spouse’s unfaithfulness on their children’s well-being, ensuring that the children’s best interests are justly safeguarded.

Discovering the Evidence of Adultery to Strengthen Your Case
Establishing adultery as a factor in a divorce case in Michigan requires more than just showing the intent or opportunity for the extramarital affair; one must also demonstrate that the act took place. In order to provide substantial evidence of your spouse’s infidelity, you may rely on various forms of communication, such as communication provided as text messages, voicemails, or emails, wherein your spouse admitted to having an affair. The presentation of these admissions in court can serve as a powerful testament to their actions.
Additionally, acquiring witness testimony from individuals, your spouse confided in about their adulterous behavior can further strengthen your case, giving you the evidence needed to establish the occurrence of infidelity. Remember that maintaining a professional and objective approach when gathering and using information presented and presenting this information will be most effective in your pursuit of proving adultery in Michigan.
Navigating Divorce Following Unfaithfulness
Discovering that your spouse has been unfaithful can be an emotionally shattering experience, leading to the difficult decision of pursuing a divorce.
Although it is natural to feel hurt and betrayed, seeking revenge through legal divorce proves adultery is not advisable. Approaching divorce after adultery is best done with a level-headed mindset rather than attempting to inflict vengeance on your spouse.
Engaging in a drawn-out battle over issues such as custody, alimony, and marital property and division will not only amplify the stress experienced by both you and your spouse but also negatively impact your children if involved.
Furthermore, contentious divorces often result in exorbitant attorneys’ fees, adding a financial burden to an already distressing situation for many marriages. It is important to remember that divorce aims to bring closure and facilitate a new beginning instead of punishing one spouse or the perpetrator of the affair.
Adultery Can Have a Significant Impact on Your Divorce Case
The presence of infidelity within a former marriage relationship can significantly impact various aspects of the legal separation process, such as property division, spousal and child support,, and custody battles.
However, obtaining concrete proof of such conduct remains challenging, especially given the vast array of digital tools and platforms that facilitate the concealment of extramarital affairs.
To gather evidence, the aggrieved spouse may need to examine web browsing histories painstakingly, examine phone records, scrutinize credit card transactions, and review work schedules.
In some instances, seeking a private investigator’s expertise might be required to substantiate one’s suspicions.
Engaging formal legal advice from a proficient family law attorney is crucial. They can provide invaluable guidance on the most effective strategies for uncovering infidelity and using that information to secure a favorable outcome in legal proceedings.
