The process of contesting a will is often complex, emotionally charged, and legally challenging. It typically arises after the loss of a loved one, when family members or beneficiaries believe that the deceased's wishes were not properly reflected in the final document. While a will is generally assumed to represent the true desires of the decedent, there are situations where individuals may wish to contest it. Understanding the grounds for contesting a will, the procedural steps involved, and the associated timelines is essential to navigating this difficult process. Working with an experienced estate attorney can help guide you through these legal complexities and ensure that your interests are properly represented.
Several legal grounds can serve as the basis for challenging the validity of a will. Below are some of the most common reasons a will may be contested:
Fraud or forgery is a significant ground for contesting a will. This occurs when the will has been altered, forged, or created under false pretenses. If a person can prove that the will presented to the court is a fraudulent document or that the decedent's signature was forged, the will may be declared invalid. Fraud may also include cases where the decedent was misled into signing the will under false information or coercion.
For example, a will may be contested if someone creates a fake will or alters an existing will to benefit themselves or others, and the decedent was unaware of the changes. In such cases, the burden of proof lies with the contesting party to demonstrate that fraud occurred.
Undue influence involves manipulating or pressuring the decedent into making decisions that they would not have made on their own. In the context of will contests, it typically refers to cases where an individual unduly influenced the decedent to create or alter a will in their favor. Undue influence can be subtle, such as emotional manipulation, or it can involve outright coercion or threats.
For example, a caregiver who isolates the elderly decedent from family members or pressures them to change their will in favor of the caregiver could be seen as exerting undue influence. To prove undue influence, the contesting party must demonstrate that the decedent’s free will was compromised by manipulation, leaving them unable to make independent decisions about their estate.
Testamentary capacity refers to the legal ability of an individual to create or modify a will. In order for a will to be valid, the decedent must have had the mental capacity to understand the nature of the document, the extent of their estate, and the consequences of distributing their assets.
If a person lacked the necessary mental faculties at the time they signed their will, it may be challenged on the grounds of lack of testamentary capacity. Common signs of lack of capacity include severe dementia, mental illness, or cognitive impairment. Contesting a will on these grounds requires evidence that the decedent was unable to comprehend or appreciate the effect of their actions when creating or updating the will.
In many cases, a physician’s testimony or expert opinion may be necessary to establish whether the decedent had the mental capacity to create a valid will. Witnesses who were present at the time of the will’s creation may also testify to the decedent’s mental state.
A will must be executed in accordance with state laws for it to be legally valid. Each state has specific requirements regarding how a will should be signed and witnessed. If the will fails to meet these requirements, it may be invalidated.
Many states require the will to be signed by the testator in the presence of at least two witnesses, who must also sign the document to confirm that they witnessed the testator’s signature. If these formalities are not followed correctly, whether due to missing signatures, improper witnessing, or a lack of notarization (when required)—the will may be challenged on the grounds of improper execution.
It’s important to note that even if the decedent intended to make a valid will, failure to adhere to legal procedures can render the document invalid.
Contesting a will is a formal legal process that involves several steps. It’s crucial to follow these steps carefully to ensure that the challenge is properly filed and considered by the court.

The first step in contesting a will is determining whether you have the legal right to do so. Typically, only individuals or entities with a financial interest in the estate, such as beneficiaries named in a prior will, heirs who would inherit under state law if no will existed, or parties named as potential beneficiaries can contest a will.
If the contested will completely disinherits you or reduces your inheritance without explanation, you likely have standing to challenge it. However, if you have no direct interest in the estate, you may not have the legal grounds to contest the will.
If you believe you have valid grounds to challenge the will, you must file a formal petition with the probate court. The petition must outline the specific grounds for the contest (e.g., fraud, undue influence, lack of capacity, improper execution), and it must be filed within a certain time frame after the will is admitted to probate.
The court will then schedule a hearing where both parties, the one contesting the will and the one defending it, can present their evidence and arguments.
During the discovery phase, both parties gather evidence that supports their respective positions. This may include medical records, witness testimony, and documents that show the decedent’s mental state at the time the will was created or evidence of coercion, fraud, or forgery.
Gathering witness testimony from those who were present when the will was signed or who can speak to the decedent’s intentions is crucial. In cases involving undue influence or lack of capacity, expert opinions, such as medical or psychological evaluations, may be necessary.
After all evidence is presented, the probate court will evaluate whether the will is valid or invalid based on the grounds for the contest. If the court determines that the will was invalid, it will typically revert to the decedent’s previous will (if there is one), or, if no valid will exists, the estate will be distributed according to state intestacy laws.
If the court determines the will is valid, the contesting party may have limited recourse, such as filing an appeal to a higher court.
The timeline for contesting a will varies depending on the jurisdiction, but most states impose a deadline for filing a will contest, often referred to as a "statute of limitations." In many cases, this deadline falls within 120 days to one year from the date the will is admitted to probate. However, the deadline may vary, so it is crucial to consult with an attorney to understand the specific timelines in your state.
Failing to file a contest within the prescribed time frame will generally result in the will being deemed valid, and the estate will be distributed according to its terms.
Challenging a will can be a complex, emotional, and legally intricate process. It’s important to approach it with clear knowledge of the grounds for contesting a will, the legal procedures involved, and the timelines that must be adhered to. Whether you are contesting a will based on fraud, undue influence, lack of testamentary capacity, or improper execution, understanding the legal framework is essential to ensuring that your challenge is taken seriously and processed correctly.
If you are considering contesting a will, it is strongly advisable to consult with an experienced probate attorney who can guide you through the legal process, evaluate the strength of your case, and represent your interests effectively.
