Quick Answers

Understanding Infidelity Clauses in Prenuptial Agreements

Infidelity clauses, often referred to as ‘no cheating clause’ or ‘cheating clauses,’ are provisions in premarital agreements that outline the repercussions of marital infidelity. These clauses can deter cheating, provide compensation to victims of the transgression, and provide a sense of security within the marriage. While once considered unusual, the incorporation of an infidelity clause in prenuptial agreements has become increasingly common, especially among high-profile or affluent couples.

Generally, an infidelity clause stipulates that a spouse guilty of adultery must pay a certain amount to the other party. For example, the clause could mandate a cheating spouse to compensate the other with $50,000.00 upon confirmation of infidelity. However, the enforceability of these clauses varies, with some states upholding them and others rejecting them. When states turn to no-fault divorce systems, it can get tough to enforce these fault provisions. In the same way, sates that have done away with the crime of adultery might also be disinclined to enforce infidelity clauses of prenuptial agreements.

The Purpose of an Infidelity Clause

An infidelity clause imposes financial penalties on a spouse proven to be unfaithful. This monetary penalty protects the aggrieved spouse’s interests by providing compensation for the emotional turmoil and financial harm caused by the betrayal. The inclusion of a prenup infidelity clause in a prenuptial agreement provides the opportunity for imposing financial penalties or a larger settlement in the event of infidelity.

At its core, the general aim of the clause is to ensure fairness. An infidelity clause outlines financial penalties or other consequences if a spouse is found to be unfaithful. This provision lends a sense of justice to the aggrieved party and may discourage the erring spouse from committing adultery. In this way, it acts as both a safeguard for the aggrieved party and a deterrent for the potential cheating spouse.

Dissipation is a legal concept that may also help in situations where a party has been unfaithful. Dissipation may apply and allow for recovery when one spouse has spent marital monies on a mistress or paramour. When marital money is spent by either spouse outside the day-to-day course of ordinary living and after the marriage has broken down, that money may be recovered through the legal theory known as dissipation. This is where a remedy may be available to the aggrieved party, even when no infidelity clause or prenuptial agreement terms have been entered into between the parties.

How Infidelity Clauses Work

Infidelity clauses function by establishing financial or other consequences for marital infidelity. They usually demand compensation for unfaithfulness, allow for a larger divorce settlement if infidelity occurs, or require a cheating spouse to forfeit specific financial benefits upon divorce. Yet, the enforcement of these clauses is not uniform across all jurisdictions.

While some states uphold infidelity clauses, others have shown a trend against their enforceability. This variability affects the ability to enforce lifestyle clauses, including infidelity clauses, making it important for couples to understand the legal landscape in their respective states before incorporating such clauses in their premarital agreements.

The Legality of Infidelity Clauses: State-by-State Differences

The legal enforceability of infidelity clauses varies dramatically across states. While some jurisdictions uphold these clauses, others reject them. Certain judges in no-fault divorce states consider it challenging to enforce infidelity clauses or any other prenuptial agreement clauses that assign fault. However, many states allow parties to opt out of the marriage and divorce laws that govern the two parties of a marriage, if doing so is part of a valid prenuptial agreement that is not against public policy. The enforceability of infidelity clauses usually comes down the exact wording of the language of the agreement.

Despite the general trend against enforceability in no-fault divorce states, there have been exceptions. Multiple no-fault divorce states have upheld cheating clauses in a prenuptial agreements. Courts in fault divorce states and no-fault divorce states alike have either upheld cheating clauses or indicated a willingness to do so, citing the admissibility of evidence of fault in a divorce in various contexts. Typically, no-fault divorce states refers to the basis or grounds for the divorce. This certainly does not necessarily mean that fault cannot be considered in any context of any divorce case.

States That Uphold Infidelity Clauses

Certain states that take adultery into account when deciding the distribution of assets in a divorce proceeding are more inclined to uphold infidelity clauses in prenuptial agreements. As well, states that are still outlaw adultery already have a legal framework for the enforceability of infidelity clauses. In contrast, states that have eliminated the old crimes of adultery from the law books may decide that enforcing infidelity clauses may not be in keeping with the new laws of their state.

Some state’s laws provide an explicit definition of adultery, requiring more than mere kissing or touching to constitute adultery. However, the specific agreement of the parties will need to have infidelity clearly defined to that there is no opportunity for confusion. Even in courts that does not uphold infidelity clauses, a spouse engaging in infidelity my still decide to agree to a larger settlement to maintain the secrecy of an affair. In other words, even infidelity clauses that are ultimately found invalid may still have the desired deterrent effect. The reason is because the cheating of the unfaithful spouse still becomes a major focal point of the divorce, which is a public proceeding.

States That Reject Infidelity Clauses

On the other hand, states like Iowa or California may reject infidelity clauses. In certain jurisdictions, the influence of infidelity on the outcome of a divorce is minimal or nil, leading these states to decline the enforcement of infidelity clauses. Other states simply decline to enforce infidelity clauses due to their policy discouraging the regulation of morals and sexual practices.

In Illinois and every other state, certain infidelity clauses are simply too extreme to be enforceable. This concept is commonly referred to as the term being unconscionable. If an infidelity clause provides that the cheater must pay the other spouse five hundred million dollars, the infidelity clause will not be enforceable.

Infidelity clauses are also commonly deemed invalid for being ambiguous or overly vague. The infidelity clause may also be rejected due to the infidelity clause being considered a liquidated damages clause. Liquidated damages clauses are contractual terms that provide a penalty for certain actions in advance, and they are discouraged under the law if the terms are not proportionate to the harm of the actions that trigger the penalty.

Including Lifestyle Clauses in Prenuptial Agreements

While infidelity clauses are the most well-known, prenuptial agreements can also include other ‘lifestyle clauses.’ These are stipulations that outline expectations on various aspects of married life, such as weight gain, rules regarding other relationships, and frequency of sexual relations. As expected, they are often unenforceable under the law.

Lifestyle clauses encompass a range of aspects, including:

If these rules are violated, the idea is that they come with repercussions as outlined in the prenuptial agreement. Nowadays, they are typically not valid and for good reason. A spouse that requires the adherence to such written expectations is most likely controlling and abusive. Fortunately, courts normally refuse to enforce these types of term because they go towards the deprivation of personal liberties that cannot be forfeited, even by voluntary agreement. Some people argue that despite them being unenforceable, these types of terms can provide a useful framework for couples to establish clear expectations and shape behavior within the marriage.

Types of Lifestyle Clauses

The predominant lifestyle clauses typically incorporated in prenuptial agreements are:

These clauses are designed to address specific concerns or behaviors within a marriage, providing expectations regarding potential areas of conflict that may arise when one spouse acts in a certain manner or the other spouse does the same.

Distinctive or atypical lifestyle clauses found in prenuptial agreements include those that impose restrictions and require a partner to compensate their spouse for breaching these restrictions. These clauses are sometimes seen in the marriage contracts of parties to fringe religious sects, celebrities, and high-income couples. While some argue such terms simply address their values and specific concerns, most people understanding that these types of terms are demanded by people controlling people and may even be abusive in nature.

Pros and Cons of Lifestyle Clauses

While lifestyle clauses can provide a framework for clear expectations in a marriage, they also have potential downsides. On the one hand, they can foster open communication and provide a sense of security by defining clear rules for behavior within the marriage.

However, lifestyle clauses have the potential to damage trust in a relationship due to their degrading nature and the perception of some individuals that they are unreasonable and wholly unnecessary. Moreover, the enforceability of such a clause could be uncertain, leading to potential conflicts. Thus, they should be drafted with caution or not at all, taking into account the specific dynamics of the relationship.

Crafting an Effective Infidelity Clause: Tips and Considerations

Crafting a practical infidelity clause involves thoughtful deliberation of what constitutes cheating, the repercussions of infidelity, and obtaining legal advice to ensure the clause is equitable, enforceable, and caters to the couple’s unique situation.

The legal terminology utilized to define cheating should encompass explicit provisions that establish consequences or compensation for infidelity. The consequences should not be extreme, but they should be fair and equitable. The consequences should apply equally between both parties, and none of the consequences should leave either party impoverished. Your marital agreement should have specific examples of what behavior constitutes infidelity, and it should include specific examples of under what circumstances the facts would not constitute infidelity. Some argue that infidelity not only includes extramarital affairs, but also includes any non-platonic relationship, modifying one’s appearance to attract others, or participating in intimate relationships with individuals other than the spouse — even when not sexual physically.

For these reasons, your infidelity clause needs to have a clear and comprehensible definition if it is going to have any chance of being enforceable.

Defining Cheating

Providing a clear definition of cheating in an infidelity clause, while difficult, is required for every enforceable infidelity clause. Without a specific definition, the clause’s enforcement becomes nearly impossible. When the meaning of the clause is not clear, demonstrating a violation of the clause can be extremely challenging. Therefore, for the clause to hold up in legal proceedings, it must explicitly detail what constitutes infidelity within the context of the marriage agreement.

The definition of cheating can encompass a range of behaviors, from physical infidelity to emotional cheating. One common definition of cheating is as follows: the establishment of a substantial and intimate connection with an individual other than one’s spouse, surpassing a platonic friendship. This definition includes emotional cheating. There can be difficulty determining if what the spouse did actually constituted cheating. For example, is it cheating if the other spouse allegedly cheated first? Can cheating occur if the person alleged of cheating claims that the marriage was already broken or that the other party already demanded a divorce? What if the no Can cheating pertain to extramarital sexual relations that are online only? Someone your spouse never met in person? Does this reflect the realities of the digital age? These questions demonstrate the difficulty that judges face, even in jurisdictions where infidelity clauses are permissible.

Ensuring Fairness and Enforceability

Just as defining infidelity is important, ensuring the fairness and enforceability of an infidelity clause is also important. Doing so allows for the formulation of transparent and just consequences for cheating and the clear understanding and voluntary consent of both parties to the clause.

A fair and enforceable infidelity clause should have clear definitions, precise consequences for breaching the clause, and should be equitable and not punitive in nature. Seeking the advice of a family law attorney is essential to ensure that the clause is legally robust and customized to the unique circumstances and requirements of the couple.

Addressing Trust Issues and Communication in Relationships

Trust is an essential component of any successful marital relationship, affecting multiple aspects such as financial matters, intimacy, decision-making, and communication. Addressing trust-related challenges involves:

Furthermore, open communication significantly contributes to building trust. Couples can enhance their communication by:

Discussing Expectations and Boundaries

Open discussions about expectations and boundaries can help mitigate misunderstandings and foster trust in a relationship. This involves transparently communicating boundaries, respecting the partner’s boundaries, and honestly addressing personal needs.

It’s also vital to address expectations with your future spouse prior to entering into a marriage. This includes:

Establishing these expectations can mitigate potential conflicts and foster a harmonious marital relationship.

Seeking Professional Guidance

Professional guidance can be beneficial in managing trust issues and crafting effective infidelity clauses. Relationship counselors can assist couples by:

Similarly, seeking legal advice is essential when drafting an infidelity clause. You want your infidelity clause to be legally robust, equitable, and tailored to the unique circumstances of the marriage. Most of all, you want your infidelity clause to be valid and enforceable, which is often challenge. Be sure to employ a family law lawyer, a divorce attorney, or prenuptial agreement attorney for help with your specific circumstances.


In conclusion, infidelity clauses in prenuptial agreements serve as a measure to protect the interests of spouses in the event of marital unfaithfulness. They provide a financial deterrent to cheating, offering a form of compensation for the aggrieved party. However, their enforceability can be questionable, with some states upholding them and others rejecting them. The language of the specific term is critical, because the language of the infidelity clause will be critically analyzed in the event of a divorce. Therefore, it is crucial for couples to understand the legal landscape in their respective states before incorporating such clauses in their agreements. Above all, trust and effective communication remain the cornerstone of a healthy marriage, with or without an infidelity clause.
