Picture this: in early 2026, an adult son in Tennessee helps his mother “save a few hundred dollars” by asking an AI chatbot to write her will. He types in the prompts, prints the document, and has her sign it at the kitchen table with a two neighbors as a witness and a mobile notary.
Eighteen months later, his siblings are filing a lawsuit contesting the will in probate court, and the estate that was supposed to pass peacefully is now hemorrhaging money on attorney fees, depositions, and expert witnesses.
With increasing adoption of AI, this scenario is happening with increasing frequency across Tennessee and other states.
Most states require strict compliance with will execution formalities. Tennessee in particular requires two witnesses to sign an attestation clause and typically a self-proving affidavit before a notary. Online templates and AI tools sometimes overlook these local requirements, meaning the resulting documents are at best vulnerable to attach and at worst completely invalid.
The central thesis is straightforward: the easier it becomes to draft wills and trusts online, the more likely those documents are to be challenged. What families expect to be a simple, inexpensive process often leads to full-blown civil litigation, contested probate, and years of dispute rather than quick, peaceful estate administration.
This article reflects the experience of Crow Estate Planning & Probate, PLC, which serves clients across Tennessee and has seen firsthand how online and AI-generated wills collapse under scrutiny in probate court.

Several modern tools have made will drafting accessible to anyone with an internet connection. National do-it-yourself will websites such as LegalZoom and Trust & Will offer step-by-step questionnaires that guide users through the process, and you can complete the entire online will questionnaire from home, saving time and effort. Online will platforms can offer flat-rate pricing or low subscriptions, providing cost savings over a traditional consultation. Online services also enable the generation of related documents like powers of attorney and living wills. Most online services allow easy updates to estate plans following life changes, and online estate planning claims to meet state-specific legal requirements through guided prompts.
Online will services provide a lower-cost alternative to traditional attorney consultations for simple estates. Step-by-step questionnaires on online platforms reduce errors by guiding users through the process. But these platforms are designed to produce a document, not to ask questions about undue influence, the mental acuity of the person executing the will, or who is exactly preparing the documents for the loved one to sign.
These tools are not licensed to practice law in Tennessee or in other states. They do not provide legal advice. They often do not adapt to state-specific rules on execution, spousal elective shares, treatment of minors, or real property transfers. Choosing the right online service should include checking for state-specific execution requirements, but most consumers never take that step.
Here is where the problem sharpens. When a son or daughter types facts into Claude, ChatGPT, or Gemini and prompts it to draft mom’s will, they are effectively preparing a legal document for someone else. Under Tennessee Code § 23-3-103, that activity could likely be viewed as the unauthorized practice of law. The statute defines “law business” broadly to include advising or assisting in selecting or completing forms that affect a person’s legal rights or interests. A family member who controls the AI prompts and directs the output is arguably exercising the kind of professional judgment the statute reserves for licensed attorneys.
AI does not establish an attorney-client relationship. It cannot ethically screen for conflicts of interest. It cannot give independent counsel. These are issues that judges and opposing counsel will highlight during litigation. An AI chatbot has no duty to the testator, no malpractice insurance, and no obligation to confirm the testator actually understands the document.
Online services and AI tools typically include broad disclaimers – “not legal advice,” “no attorney-client relationship” – which actually undercut the will’s credibility when the drafting process is examined in a contested probate hearing. Those disclaimers become exhibits for the party challenging the will, used to argue that the testator never received genuine legal guidance. As we have previously discussed, national platforms are often not the best choice for Tennessee residents.
When an online will is offered for probate, it is first tested against statutory formalities. If challenged, the proceeding can escalate into full civil litigation with discovery, depositions, and expert testimony on capacity and influence. What was supposed to be a cost-saving measure becomes the most expensive decision the family ever made.
Heirs who feel wronged by an online or AI-generated will have numerous angles of attack. These weaknesses make online wills magnets for lawsuits and alternative dispute resolution efforts. Below are the primary vulnerabilities that courts in Tennessee consistently examine.
Tennessee courts look carefully at whether the testator had their own attorney. An AI chatbot or a website does not satisfy this requirement. When a will is prepared without independent counsel, and the primary beneficiary was involved in the drafting, courts treat the absence of a lawyer as a suspicious circumstance.
Consulting an attorney is recommended for complex estate situations involving substantial assets. But even for modest estates, the lack of independent counsel removes the critical safeguard of having someone ensure the testator’s wishes are freely expressed and properly documented.
Undue influence is one of the most powerful grounds for contesting a will. In Tennessee, when there is a confidential or fiduciary relationship between the testator and a beneficiary, and that beneficiary was active in procuring the will and benefits under it, the law presumes undue influence. The proponent of the will must then rebut that presumption by clear and convincing evidence.
Consider an adult child who manages a parent’s finances, provides daily care, controls access to the parent’s devices, and then uses those devices to generate a will through AI – a will that leaves everything to that child. The confidential relationship is established. The child’s involvement in drafting is established. The benefit is obvious. The presumption of undue influence attaches, and without independent counsel or other evidence of fairness, it may be impossible to overcome.
Tennessee case law, instructs courts to examine multiple suspicious circumstances: the testator’s physical or mental deterioration, secrecy surrounding the will, the beneficiary’s involvement in the process, and whether the distribution upends natural expectations. In one case in particular, a Tennessee court found that the absence of independent legal advice, combined with a confidential relationship, was sufficient to sustain the presumption that the child had wrongfully influenced their parent to execute a will which was favorable to that child.
Challengers will question whether mom or dad understood what they were signing. Testamentary capacity requires that the testator understand the nature of the act, know the extent of their property, recognize the natural beneficiaries of their estate, and grasp the implications of the disposition they are making.
When a will is executed at home without a lawyer or neutral witnesses who can later testify about the testator’s mental state, capacity challenges become difficult to defend. AI tools do not perform cognitive assessments. They do not ask follow-up questions when answers seem confused. There is no record of the testator’s demeanor, alertness, or understanding at the time of execution, only a printed document and a signature.
Validating an online will typically requires physical signatures and witnesses, according to state laws. Legal requirements for witnessing and notarizing a will can vary significantly by state, and this is where online wills most frequently fail.
In Tennessee, the April 2025 decision in In Re Estate of Nancy Riss illustrates how strictly courts enforce these rules. The court invalidated a codicil because witness signatures appeared on an affidavit rather than on the codicil itself. A separate holographic document failed because it lacked material provisions directing the disposition of the estate. These are exactly the types of errors that online and AI-generated wills produce: witnesses signing at different times, signatures in the wrong places, or no notarization at all.
As we have noted in our discussion of handwritten wills in Tennessee, even documents that appear straightforward can be invalidated when formalities are not met.
Generic AI clauses often conflict with Tennessee elective-share rights, homestead and exempt property statutes, or the particular needs of blended families and business owners. When a will uses boilerplate language that does not account for a surviving spouse’s statutory rights, or when it misidentifies property or mishandles business interests, the result is interpretive disputes that require a judge to determine what the testator actually intended.

Understanding how a contested online will moves through the court system is important for anyone who has used, or is considering, an AI-generated estate plan.
Litigation begins when an executor files to probate the purported will with the probate court. A dissatisfied heir may then file an objection or will contest, alleging undue influence, lack of capacity, fraud, or improper execution. As outlined in our overview of how will contests work in Tennessee, the objecting party must state the grounds for the challenge and serve notice on all interested parties.
Defendants have 30 days to file an answer, depending on the court and the nature of the action. Once an answer is filed, the case is set on a track toward discovery, motions, and potentially trial.
The discovery period allows parties to exchange evidence before trial. In an will contest of an online will, this phase takes on particular significance. Lawyers may request:
If prompt logs show that the child, and not the parent, selected every provision of the will, that fact will be presented to the judge or jury as evidence that the testator did not exercise independent judgment.
Because online will cases can polarize and ultimately destroy families, judges often encourage mediation or other forms of alternative dispute resolution. These proceedings allow the parties to negotiate a settlement, such as redistributing estate assets or acknowledging certain bequests, without the cost and emotional toll of a full trial. Crow Estate Planning & Probate, PLC has experience using alternative dispute resolution to resolve will contests efficiently, protecting both estates and family relationships when a negotiated outcome is possible.
If mediation fails, the case proceeds to trial. Witnesses may include the parties, neighbors, an expert on digital evidence, medical professionals who can testify about capacity, and family members who observed the circumstances of the will’s execution. Most probate contests are heard in state court where the judge may serve as fact-finder depending on the type of proceeding.
After a verdict or judgment, either party may seek post-trial relief. Post-trial motions can be filed to overturn or adjust verdicts. If a party believes the trial court misapplied Tennessee law on capacity, undue influence, or execution standards, an appeal to the Court of Appeals may follow, adding months or years to a dispute that an online will was supposed to prevent.

Working with a local estate planning attorney in Tennessee can dramatically lower the chance of a will contest or expensive civil litigation. The contrast with an online or AI-generated will is stark.
An attorney documents the testator’s capacity through in-person meetings, contemporaneous notes, and, when appropriate, referrals for medical opinions or witness affidavits. These records provide concrete evidence that the client understood their decisions at the time of signing. That evidence can be the difference between a will that is enforced and one that is set aside.
Independent counsel eliminates the presumption that a favored child or caregiver controlled the process. When a licensed attorney prepares the will, the lawyer, not the beneficiary, directs the content and ensures the client’s free will is expressed. Courts give significant weight to the involvement of independent counsel when evaluating claims of undue influence, as discussed in our guide on what you can do to prevent your will from being contested.
An attorney schedules in-office signings with two qualified witnesses present simultaneously, a notary for self-proving affidavits, and clear procedures so the will meets Tennessee statutory requirements. There is no ambiguity about whether both witnesses were in the room, whether the testator signed voluntarily, or whether the document was properly notarized.
Estate planning involves more than filling in blanks on a form. For many families, the right approach includes revocable living trusts, special needs trusts, business succession plans, and powers of attorney tailored to the client’s assets and family dynamics. These tools, selected and drafted by a licensed attorney, address scenarios that online platforms simply cannot anticipate.
Careful drafting anticipates potential civil litigation. An experienced attorney may include no-contest clauses where appropriate, clarify reasons for unequal distributions, and address known family conflicts directly in the document. These measures deter future lawsuits and give the will the best chance of being admitted to probate without objection.
If you are in Tennessee and have an existing online or AI-generated will, now is the time to have it reviewed. Schedule a consultation with Crow Estate Planning & Probate, PLC before that document is needed in a courtroom.

Is an will prepared online legally valid in Tennessee?
An will prepared online can be legally valid in Tennessee if it satisfies all statutory execution requirements such as proper signatures, two competent witnesses present at the same time, and, for self-proving status, a notarized affidavit. The problem is that many online wills do not meet these requirements. Tennessee courts have shown they will strictly enforce formalities. The fact that a will was created online does not automatically make it invalid, but the conditions under which it was executed will determine whether it holds up if challenged. If you have any question about whether your online will meets state law, having it reviewed by a local probate attorney is the most reliable way to find out.
Can a loved one legally prepare a parent’s AI-generated will?
In Tennessee, this activity carries serious legal risk. Under Tennessee Code § 23-3-103, preparing legal documents that affect another person’s rights can constitute the unauthorized practice of law (UPL) when it requires the exercise of professional legal judgment. A son or daughter who selects the AI prompts, inputs the information, and directs the output is arguably engaging in that prohibited conduct. Beyond the UPL issue, the child’s involvement creates powerful ammunition for a will contest. If the child also has a confidential relationship with the parent (a caregiver, financial manager, or holder of power of attorney) and the will benefits the child, Tennessee courts will presume undue influence. The child would then bear the burden of proving by clear and convincing evidence that the will was the product of the parent’s free and informed choice, not the child’s control. Without independent counsel and documented capacity, that burden is extremely difficult to meet.
What should I do if a family member died leaving only an online or AI-generated will?
The first step is to consult with a probate and estate administration attorney before the will is offered for probate. An attorney can evaluate whether the document meets Tennessee execution requirements and identify vulnerabilities that might invite a contest. If you believe the will does not reflect the decedent’s true wishes, or if there are grounds to challenge capacity, undue influence, or execution defects, your attorney can advise you on the options for filing a will contest. Acting quickly matters as Tennessee imposes deadlines for contesting a will, and missing those deadlines can waive your rights entirely. Gathering information early, including any records of how the will was created, who was involved, and the decedent’s health at the time, will support your position whether you are defending or challenging the document.
Can mediation or alternative dispute resolution resolve a will contest without a full trial?
In many cases, yes. Mediation allows all parties to negotiate a resolution with the help of a neutral mediator, often resulting in a redistribution of assets or acknowledgment of certain bequests that avoids the financial and emotional costs of trial. Courts in Tennessee frequently encourage or order mediation in probate disputes. Alternative dispute resolution is particularly effective when the dispute centers on ambiguous language or unequal distributions rather than outright fraud or forgery. However, where the will suffers from fundamental execution defects, such as missing witnesses or the complete absence of a testator’s signature, a court may need to rule on validity as a matter of law before settlement is possible. Crow Estate Planning & Probate, PLC regularly helps clients explore alternative dispute resolution as a first step in contested estate matters.
How much does it cost to litigate an online will contest compared to hiring an attorney to draft a proper will?
The disparity is significant. A professionally drafted will with proper execution typically costs a fraction of what even a modest probate contest involves. Contested probate proceedings can require many thousands of dollars in attorney fees, expert witness fees, digital forensics, depositions, and court costs and the process can take years to resolve through trial and appeal. Online will platforms may advertise savings through flat-rate pricing or low subscriptions, but those savings evaporate if the document is challenged. In many of the cases our firm has handled, the litigation costs have exceeded the total value of the estate, meaning no one benefits. Investing in proper estate planning from the start is consistently the most cost-effective option. Investing in proper estate planning from the start is consistently the most cost-effective option for Tennessee residents. Working with a local Tennessee estate planning attorney ensures compliance with state-specific legal requirements, including strict witnessing and execution formalities under Tennessee law. This approach reduces the risk of will contests and costly civil litigation that often arise from online or AI-generated wills. Tennessee courts give significant weight to the presence of independent counsel, proper execution, and documented testamentary capacity, all of which are best established through personalized legal services rather than generic online platforms. By choosing professional estate planning tailored to Tennessee law, families can better settle their affairs peacefully and avoid the pitfalls of contested probate proceedings.
