Understanding the Grounds for Contesting a Divorce in Rancho Cucamonga

Divorce can be challenging, often fraught with emotional and legal complexities. If you believe your divorce should be contested, it’s crucial to understand the grounds on which you can build your case. 

At the Law Office of Laurence J. Brock, our experienced family law attorneys in Rancho Cucamonga are here to guide you through the entire process.

What It Means to Contest a Divorce

Challenging a divorce is not something couples usually plan on doing when they get married. However, sometimes things don’t work out as planned, and the only way to move forward is to file for divorce. Sometimes one spouse contests the divorce, leading to a complicated process. This post will discuss what it means to contest a divorce.

Disagreement on Divorce Terms

When one spouse files for divorce, they usually have terms in mind regarding how assets will be divided and child custody arrangements will be made. If the other spouse disagrees with these terms or believes they are unfair, they may contest the divorce. This means both parties must go through a legal process to develop mutually agreeable terms.

Legal Process Involved

Contesting a divorce can mean additional time and expenses in the legal process. The couple may need to attend court hearings and mediation sessions to reach an agreement. If they cannot do so, a judge will make decisions on their behalf based on evidence presented during court proceedings.

Impact on Children

If there are children involved in the marriage, contesting a divorce can impact them as well. Going through court proceedings and mediation sessions can be stressful for children who may not understand what is happening or why their parents are fighting over custody arrangements.

Understanding Grounds for Divorce

Divorce is a difficult and emotional process, and it can be made even more complicated by the legal grounds required to file for divorce. To obtain a divorce, one must have valid grounds that meet their state’s or country’s legal requirements. Grounds refer to why a person seeks a divorce and vary depending on the jurisdiction.


One of the most common grounds for divorce is adultery, which refers to when one spouse engages in sexual activity with someone other than their spouse. Adultery can be difficult to prove, but if it can be established through evidence such as photographs or messages, it may be used as a ground for divorce. However, in some jurisdictions, adultery may not be recognized as a valid ground for divorce if both parties engage in extramarital affairs.


Another common ground for divorce is abandonment, which occurs when one spouse leaves the marital home without justification or consent from the other spouse. Abandonment can include physical separation or emotional detachment and may require proof that the absent spouse has no intention of returning.


Cruelty is another potential ground for divorce that refers to physical or mental abuse inflicted by one spouse on the other. This includes acts of violence, threats of harm, verbal abuse, and psychological manipulation. Proving cruelty often requires testimony from witnesses or medical professionals who can attest to any injuries sustained by the victim.


Incompatibility is a no-fault ground for divorce that does not require either party to prove wrongdoing by their spouse

Instead, it simply means that irreconcilable differences exist between spouses, making it impossible to continue their marriage. Incompatibility may also refer to different life goals or values, financial disagreements, or sexual incompatibility.

Common Grounds for Contesting a Divorce

Grounds for contesting a divorce refer to the legally recognized reasons or arguments that a spouse may present in court to challenge the divorce proceedings. These grounds provide a basis for disputing the validity or terms of the divorce, potentially influencing the outcome.

Some common grounds for contesting a divorce are:

  • Lack of Jurisdiction: The Importance of Proper Venue

One of the most common reasons spouses may contest a divorce is lack of jurisdiction. This means the court where the divorce was filed has no authority to hear and decide on the case. Jurisdictional issues can arise when one spouse lives in another state or country or multiple states are involved. In such situations, it’s important to ensure that you file for divorce at the proper venue.

  • Fraud and Misrepresentation

In some cases, divorce proceedings are initiated on the basis of fraud or misrepresentation. Fraud and misrepresentation refer to situations where one spouse deliberately deceives the other about a key aspect of the marriage, such as finances, property ownership, or fidelity. When this happens, it can be grounds for contesting a divorce. Here are some important things about fraud and misrepresentation in divorce cases.

What Constitutes Fraud and Misrepresentation?

Fraud is defined as intentional deception intended for personal gain or harm. In divorce, fraud may occur when one spouse lies about their income or assets to gain an advantage in property division negotiations. For example, a spouse might hide significant assets by transferring them to a secret bank account or falsely claim they have less income than they actually do.

Misrepresentation involves making false statements or withholding information that would affect the other spouse’s decision-making process during the marriage. For instance, if one spouse concealed their infidelity history before getting married and only revealed it after filing for divorce, this could be considered misrepresentation.

Proving Fraud and Misrepresentation

Proving fraud or misrepresentation can be challenging since it often involves showing that one spouse intentionally deceived the other. However, several types of evidence can support these claims:

  • Bank statements: If one spouse is suspected of hiding assets, bank statements can reveal unusual transactions.
  • Emails and text messages: These communications may contain incriminating evidence, such as admissions of deceit.
  • Witness testimony: Friends or family members who were aware of the deception may be able to testify supporting your case.
  • Forensic accounting: This investigation can uncover hidden assets or other financial irregularities.
  • Duress or Coercion

Duress or coercion is another ground for contesting a divorce. If one spouse was forced into getting married against their will or threatened with harm if they didn’t agree to marry, they could argue that they were under duress at the time of marriage.

  • Mental Incapacity

Mental incapacity, as grounds for contesting a divorce, refers to a situation where one spouse claims the other spouse lacks the mental capacity to understand the nature and consequences of the divorce proceedings. It suggests that the spouse seeking divorce is incapable of making informed decisions or consenting to the divorce due to a mental condition or illness.

In some jurisdictions, mental incapacity may be a valid ground for contesting a divorce, but the specific laws and requirements can vary. Here are some general points to consider:

  • Lack of Understanding

The contesting spouse must demonstrate that the other spouse lacks the mental capacity to comprehend the nature of the divorce and its consequences. This could be due to a mental illness, cognitive impairment, or other factors significantly affecting their ability to understand and make decisions.

  • Legal Capacity Standards

Courts often assess the mental capacity of an individual based on certain legal capacity standards. These standards can vary by jurisdiction but typically involve determining if the individual can comprehend the nature of the divorce, appreciate the potential consequences, and make rational decisions.

  • Medical or Expert Evidence

In most cases, the contesting spouse must provide medical or expert evidence to substantiate their claim of mental incapacity. This evidence may come from doctors, psychologists, or other qualified professionals who evaluate the spouse’s mental health and capacity.

  • Burden of Proof

The burden of proof generally rests on the contesting spouse establishing the mental incapacity claim. They must present sufficient evidence to convince the court that the spouse seeking the divorce lacks the mental capacity.

  • Impact on Divorce Proceedings

If mental incapacity is successfully proven, it may have various implications for divorce proceedings. The court might appoint a guardian ad litem or an advocate to represent the spouse with mental incapacity and ensure their interests are protected. Depending on the jurisdiction, it could also affect property division, spousal support, child custody, and visitation rights.

  • Invalidity of Marriage

Marriage invalidity is grounds for contesting a divorce based on the assertion that the marriage is legally invalid or void. This means that the marriage is considered to have never existed in the eyes of the law. If a party believes the marriage is invalid, they can contest the divorce on this ground.

There are several situations in which a marriage may be deemed invalid:

  • Bigamy: If one spouse was already legally married to another person when the marriage was contested, the subsequent marriage is invalid.
  • Consanguinity: In cases where the spouses are closely related by blood, such as siblings or close relatives, the marriage may be invalid due to laws prohibiting incestuous relationships.
  • Age restrictions: If one or both parties were underage and had no legal capacity to enter into marriage, the marriage may be deemed invalid.
  • Irreconcilable Differences

“Irreconcilable differences” implies a significant breakdown in the marital relationship, making it impossible or impractical for spouses to continue their marriage. It is often used in no-fault divorce jurisdictions where neither party must prove fault or wrongdoing.

When citing irreconcilable differences as grounds for contesting a divorce, one spouse believes that the marriage can still be salvaged or that the differences between the spouses are not significant enough to warrant a divorce. This ground allows the contesting spouse to argue against the dissolution of the marriage and request reconciliation or counseling instead of divorce.

However, it’s important to note that in many jurisdictions, irreconcilable differences alone may not prevent a divorce. Courts generally respect the right of individuals to end their marriage if they believe it is irretrievably broken. In such cases, the court may focus on an equitable division of property, child custody, support, and other related matters rather than reconciling the parties.

Contesting a divorce based on irreconcilable differences typically involves presenting evidence or arguments that support the contention that the marriage can be saved or that the differences are not insurmountable. This may include making efforts to reconcile, seeking counseling or therapy, or showing that the issues causing the breakdown can be resolved through alternative means. Ultimately, the court will decide based on the parties’ best interests.

  • Non-compliance with Legal Procedures

Non-compliance with legal procedures refers to failing to follow the required legal steps or meet the procedural requirements for initiating or pursuing a divorce. It can serve as grounds for contesting a divorce if one spouse believes that the proper legal procedures were not followed, potentially impacting the validity or fairness of the divorce process.

Some examples of non-compliance with legal procedures that may be used as grounds for contesting a divorce include:

If the spouse initiating the divorce fails to properly serve the divorce papers to the other spouse according to the jurisdiction’s legal requirements, it can be argued that proper notice was not given, leading to a contested divorce.

  • Failure to Meet Residency or Jurisdictional Requirements

Each jurisdiction has specific residency or jurisdictional requirements that must be met before filing for divorce. If these requirements are not fulfilled, the divorce may be challenged because of lack of jurisdiction or improper venue.

  • Procedural Errors in Filing or Responding to the Divorce Petition

If there are substantial errors or omissions in the filing or response documents, it can be argued that the procedural requirements were not met, potentially leading to a contested divorce.

  • Non-compliance with Mandatory Waiting Periods

Some jurisdictions impose mandatory waiting periods before a divorce can be finalized. If one party seeks to rush the process or bypass the waiting period without proper legal justification, it may be contested on non-compliance with waiting period requirements.

  • Failure to Disclose or Provide Accurate Financial Information

In many divorces, full and accurate financial disclosure is required. If one spouse fails to provide complete and honest information about their assets, debts, or income, it can be grounds for contesting the divorce based on non-compliance with financial disclosure requirements.

When contesting a divorce based on non-compliance with legal procedures, the contesting spouse must demonstrate how the non-compliance has prejudiced their rights or affected the fairness of the divorce process. This may involve presenting evidence of specific procedural errors or violations and arguing that they warrant reconsideration or invalidation of the divorce proceedings.

  • Marital Misconduct

Refers to behaviors or actions by one spouse that are considered inappropriate, harmful, or detrimental to the marriage. When citing marital misconduct as grounds for contesting a divorce, one spouse believes that the behavior of the other spouse justifies contesting the divorce and potentially seeking a different outcome or resolution.

Examples of marital misconduct that may be used as grounds for contesting a divorce include:

  • Adultery

When one spouse engages in extramarital affairs or sexual relationships outside the marriage, the other spouse may contest the divorce on the grounds of adultery. They may argue that the behavior of the adulterous spouse caused significant harm to the marital relationship.

  • Domestic Abuse

If there is a history of physical, emotional, or sexual abuse within the marriage, the victimized spouse may contest the divorce based on the grounds of domestic violence. They may argue that abusive behavior demonstrates the marriage breakdown and may seek protective measures or a different division of assets.

  • Substance Abuse or Addiction

When one spouse has a substance abuse problem or addiction significantly affecting the marriage, the other spouse may contest the divorce for marital misconduct. They may argue that the addicted spouse’s behavior and actions have harmed the marriage and seek appropriate remedies.

  • Financial Misconduct

If one spouse engages in financial misconduct, such as hiding assets, dissipating marital funds, or engaging in fraudulent financial activities, the other spouse may contest the divorce for financial misconduct. They may argue that the actions of the financially irresponsible spouse warrant a different division of assets or financial compensation.

It’s important to note that the relevance and impact of marital misconduct as grounds for contesting a divorce can vary depending on the jurisdiction and specific circumstances of the case. Courts may consider the nature and severity of the misconduct, its impact on the marital relationship, and the overall equitable resolution of divorce proceedings.

When contesting a divorce based on marital misconduct, the contesting spouse must provide evidence of the misconduct and present arguments supporting their claim for a different outcome or resolution. Consulting with an experienced family law attorney at The Law Office of Laurence J. Brock can provide guidance on how best to present the case and navigate the legal process.

  • Unfair Distribution of Assets

Unfair distribution of assets refers to the perceived inequitable division of property, finances, or assets during the divorce process. When citing unfair distribution of assets as grounds for contesting a divorce, it means that one spouse believes that the division of assets in the divorce settlement is unjust or biased and seeks to challenge the distribution to obtain a more favorable outcome.

Some situations that may lead to contesting a divorce based on unfair distribution of assets include:

  • Hidden or Undisclosed Assets

If one spouse suspects that the other spouse has concealed assets or provided inaccurate financial information during the divorce proceedings, they may contest the divorce on the grounds of unfair distribution. They may argue that a more comprehensive assessment of assets is necessary to ensure an equitable division.

  • Dissipation of Marital Assets

Suppose one spouse recklessly or intentionally dissipates marital assets (such as spending money on unnecessary expenses, excessive gambling, or extravagant gifts for a third party) prior to or during the divorce process. In that case, the other spouse may contest the divorce based on unfair distribution. They may argue that the dissipation of assets should be considered when dividing the remaining assets.

  • Significant Financial Disparity

If there is a substantial difference in the spouses’ financial resources or earning capacity, one spouse may contest the divorce for unfair distribution. They may argue that a more favorable division of assets is necessary to ensure a fair and reasonable financial outcome.

  • Non-Marital Property Inclusion

If non-marital assets or property, such as inheritances or pre-marital assets, are erroneously included in the division of marital assets, a spouse may contest the divorce on the grounds of unfair distribution. They may argue that the non-marital property should be excluded or treated differently in the division process.

When contesting a divorce based on unfair distribution of assets, it is important to gather evidence, such as financial records, documentation of hidden assets, or expert opinions, to support the claim of inequitable distribution. Seeking the guidance of a knowledgeable divorce attorney can help build a strong case and advocate for a fair and just division of assets in the divorce settlement.

  • Child Custody and Support

Child custody and support are critical aspects of divorce, and they can serve as grounds for contesting a divorce when one parent believes that the proposed custody arrangement or support agreement is not in the child’s best interests or is unfair. Contesting a divorce based on child custody and support typically involves the following grounds:

  • Best Interests of the Child

If a parent believes that the proposed custody arrangement does not prioritize the child’s best interests, they may contest the divorce on this ground. They can argue that the child’s well-being, safety, and development require a different custody arrangement that better promotes their welfare.

  • Parental Fitness

If one parent believes that the other is unfit or incapable of providing proper care for the child, they may contest the divorce on the grounds of parental fitness. They can present evidence demonstrating neglect, abuse, substance abuse, or other factors that could harm the child’s well-being.

  • Parental Alienation

If one parent believes that the other parent is intentionally alienating the child from their relationship, they may contest the divorce on the grounds of parental alienation. They can present evidence of actions or behaviors by the other parent that undermine their relationship with the child.

  • Financial Support

If a parent believes that the proposed child support arrangement is unfair or does not adequately meet the child’s needs, they may contest the divorce for inadequate financial support. They can present evidence of the child’s expenses, the income of both parents and other relevant factors to support their claim for a different child support arrangement.

  • Modification of Existing Custody or Support Orders

Sometimes a parent may contest the divorce based on the need to modify an existing custody or support order. They may argue that a change in circumstances, such as a parent’s relocation, a significant change in income, or the child’s evolving needs, warrants a modification of the existing orders to better serve the child’s interests.

When contesting a divorce based on child custody and support, it is crucial to gather relevant evidence, such as witnesses, documentation of the child’s best interests, financial records, or expert opinions, to support the claim. 

Exploring Alternative Options Before Contesting a Divorce

Divorce is never easy, and it can be incredibly stressful for both parties involved. It’s important to know that alternative options are available before contesting a divorce in court. 

Here are some methods to consider:


Mediation is a process where both parties work with a neutral third-party mediator to agree. The mediator facilitates communication between the two parties, but does not make decisions. Mediation can be less expensive and time-consuming than court, often results in a more amicable resolution.

Collaborative Divorce:

Collaborative divorce is another option that involves working with professionals such as lawyers, financial advisors, and therapists to reach an agreement outside of court. Both parties sign an agreement to resolve their issues without court. Collaborative divorce can be beneficial because it allows both parties to have more control over the outcome of the divorce.


Arbitration is similar to mediation as it involves a neutral third party who resolves disputes. However, unlike mediation, the arbitrator can decide for the couple if they cannot agree on something. This method can be more expensive than mediation but less expensive than traditional litigation.


Negotiation involves both parties attempting to come up with an agreement on their own or with the help of their attorneys without involving third-party professionals like mediators or arbitrators. This method can save time and money compared to litigation, but it requires effective communication skills from both parties.

Remember that each couple’s situation is unique, and what works for one may not work for another. It’s crucial for couples considering alternative methods before contesting a divorce in court to seek legal advice before proceeding forward.

Importance of Hiring an Attorney for Contesting a Divorce

Going through a divorce can be a difficult and emotional. It can become even more complicated when one party contests the divorce. In such cases, hiring an experienced attorney who can help you navigate through the legal system and protect your interests is essential. 

Here are some reasons why hiring an attorney is crucial when contesting a divorce:

Protect Your Rights and Interests

When contesting a divorce, you need to ensure your rights and interests are protected. An experienced attorney can help you understand your rights, explain how they apply to your situation, and provide guidance on protecting them. They will also work with you to identify potential issues during the process and develop strategies to address them.

Navigating Complex Legal Procedures

Divorce procedures can be complex, especially when contested. Many legal requirements must be met, including filing paperwork within specific timelines and attending court hearings. An experienced attorney will have in-depth knowledge of these procedures and can guide you through each step of the process.

Negotiate Settlements

In most contested divorces, parties try to negotiate settlements outside of court. This process requires skillful negotiation tactics that only an experienced attorney possesses. They will work with you to identify what you want from the settlement agreement and negotiate with your spouse’s lawyer on your behalf.

Provide Emotional Support

Divorce proceedings can be emotionally draining for all parties involved. An experienced attorney understands this and provides legal support and emotional support throughout the process. They will listen to your concerns, offer advice on coping with stress and provide reassurance during challenging times.

There have been several instances where individuals who contested their divorces without proper legal representation ended up losing everything they had worked hard for in life–assets, properties, businesses, or even custody of their children–due to a lack of knowledge, experience, or legal representation. 

In contrast, those who hired an experienced attorney got a fair settlement and protected their interests. Contesting a divorce can be complex and emotional. It involves challenging the legal validity of divorce on specific grounds that may vary by jurisdiction. These grounds could range from fraud and misrepresentation, duress and coercion, lack of mental capacity, and more.

If you are considering contesting a divorce, it is crucial to understand the various grounds for doing so and how they can affect your case. Each ground has specific requirements for evidence and proof in court.
