TL;DR:<\/strong> The legal process of contesting a Will involves four primary grounds which include testamentary incapacity because the testator lacked mental capacity and undue influence because someone forced the testator and improper Will execution and the discovery of a later Will or codicil. You cannot contest a Will simply because you were verbally promised something, because you feel you \u201cdeserve\u201d a share, or because the Will was written using an online service. A properly signed and witnessed Will – whether prepared by a lawyer or an online service – has full legal standing.<\/p>\n<\/div><\/div>\n\n\n\n

Can You Contest a Will?<\/h2>\n\n\n\n

The publication of a Will after death often brings unexpected results which family members and friends did not anticipate. People doubt the Will\u2019s authenticity because they suspect someone forced the testator to create the document. The inheritance process sometimes reveals that people who expected to receive property actually become victims of total exclusion from the entire estate.<\/p>\n\n\n\n

What Are the Legal Grounds for Contesting a Will?<\/h2>\n\n\n\n

There are four main grounds on which a Will can be successfully challenged:<\/p>\n\n\n\n

Ground<\/th>What It Means<\/th>Burden of Proof<\/th><\/tr><\/thead>
Lack of testamentary capacity<\/strong><\/td>The testator was not of “sound mind” when the Will was made<\/td>Must show testator did not understand the nature of the document<\/td><\/tr>
Undue influence<\/strong><\/td>Someone in a position of trust pressured the testator<\/td>Must show confidential relationship and abuse of that trust<\/td><\/tr>
Failure to meet formalities<\/strong><\/td>The Will was not properly signed, witnessed, or dated<\/td>Must show specific procedural requirements were not met<\/td><\/tr>
Later Will or codicil<\/strong><\/td>A more recent valid Will or amendment exists<\/td>Must produce the later document and prove its validity<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

What Is Testamentary Capacity?<\/h2>\n\n\n\n

Testamentary capacity defines the legal requirement which demands Will creators to maintain \u201csound mind\u201d status during their Will creation process. The courts of almost every U.S. state determine whether the testator possessed adequate mental capacity when they created their Will.<\/p>\n\n\n\n

    \n
  1. The testator knew what a Will represented because they understood they were creating a document which would control their estate through legal authority.<\/li>\n\n\n\n
  2. The testator knew who would normally benefit – understood that Wills typically provide for a spouse and children<\/li>\n\n\n\n
  3. The testator understood their property holdings because they recognized their ownership of a house and bank accounts and retirement benefits and vehicles and personal belongings.<\/li>\n\n\n\n
  4. The testator understood asset distribution because they knew which people usually receive assets yet they could make special exceptions for certain situations.<\/li>\n<\/ol>\n\n\n\n

    The courts demand strong proof about testator ignorance before they would declare a Will invalid. Medical evidence – such as a doctor certifying advanced dementia – can support a finding of lack of capacity. However, early-stage dementia or having cancer does not automatically invalidate a Will.<\/p>\n\n\n\n

    The testator does not need to understand every legal term in the Will. The document remains valid because the testator understood the overall purpose and result which their Will would create.<\/p>\n\n\n\n

    What Is Undue Influence?<\/h2>\n\n\n\n

    Undue influence represents the main reason which people use to fight against Will validity. The testator becomes victim of undue influence when someone who holds their trust uses this position to force them into changing their Will for personal benefit. The courts evaluate four essential elements during their decision-making process.<\/p>\n\n\n\n

      \n
    1. An unusual distribution:<\/strong> A relative who would normally inherit is excluded, while someone else receives more than expected. If all family members are excluded in favor of a personal caretaker, that is a significant red flag.<\/li>\n\n\n\n
    2. A confidential relationship existed: Seniors and those in ill health often rely on a caretaker for physical and emotional needs. The system depends on others which makes it vulnerable to outside control.<\/li>\n\n\n\n
    3. The person in the confidential relationship benefited:<\/strong> The individual who had the close relationship with the testator received the unusual distribution.<\/li>\n\n\n\n
    4. Someone who held trust authority abused this position through actions which separated the testator from their family members while they also managed financial data and controlled the entire situation.<\/li>\n<\/ol>\n\n\n\n

      A confidential relationship is often presumed if the beneficiary lived in the same home as the testator. However, an unusual distribution alone is not sufficient – there may be legitimate reasons. A father might choose to give all his property to one daughter because she remained in touch with him while she took care of him.<\/p>\n\n\n\n

      What Will Formalities Must Be Met?<\/h2>\n\n\n\n

      Each state has specific requirements for a valid Will. The list of formalities which people commonly follow contains these elements:<\/p>\n\n\n\n
