When a loved one’s will feels like a betrayal of their true intentions, the sense of injustice is overwhelming. Challenging that document, or contesting a will in court often seems like the only path to setting things right.
But as a financial planner with three decades of “scar tissue,” I have seen these battles up close. They are wars of attrition, fought with money, time, and emotional fortitude. Before you spend a single dollar on a retainer, you must move from “betrayed heir” to “calculated strategist.”
Now, with the One Big Beautiful Bill Act (OBBBA) permanently setting the federal estate tax exemption at $15 million as of January 1, 2026, will contests are exploding in high-value estates. The stakes for a multimillion-dollar inheritance have never been higher, and the court’s scrutiny has never been tighter. [IRS Publication 559]
🆕 2026 Estate Planning Context
With the One Big Beautiful Bill Act (OBBBA) signed July 4, 2025, the federal estate tax exemption is now permanently $15 million per individual ($30 million for couples) starting January 1, 2026. Will contests are increasingly common in high-value estates as beneficiaries fight over multimillion-dollar inheritances. Understanding your legal standing and viable grounds has never been more critical.

Step 1: Clearing the “Standing” Gatekeeper
You cannot contest a will just because you were “wronged.” To even enter the courtroom, you must have legal standing. This is the judicial gatekeeper that prevents frivolous litigation by requiring you to be an “interested party.”
To have standing, you must prove you are:
- A Named Beneficiary: You are in the current will but received less than promised.
- A Prior Beneficiary: You were in a previous version of the will but were removed.
- An Heir-at-Law: You would inherit automatically under intestacy succession laws if the will were thrown out.
- Standing is Binary: If you aren’t an “interested party,” the court will dismiss your case in 10 minutes.
- The 90-Day Window: Many states, including Texas , have strict windows to file a “caveat” or challenge after probate notice is served.
- Capacity is Hard to Disprove: The law presumes the testator was sane. The burden of proof rests entirely on you.
Step 2: The 4 Pillars of Probate Litigation
Your challenge must be built on one of these four specific legal grounds. Your feelings are valid, but they are not evidence.
1. Lack of Testamentary Capacity (The “Sound Mind” Test)
This argues the testator didn’t understand three things: the nature of their assets, their “natural objects of bounty” (family), and the document they were signing.
The Lucid Interval Doctrine:
Here is what generic guides miss: In 2026, a diagnosis of dementia does not automatically invalidate a will. Courts recognize “Lucid Intervals”, temporary windows of clarity where a patient is legally capable of signing documents. To win, you must prove they lacked capacity at the exact moment of execution.
If the testator was in hospice, check the Pharmacy Logs. The use of high-dose analgesics (Morphine) or benzodiazepines (Ativan) creates a rebuttable presumption of incapacity. In 2026, medical expert witnesses use “half-life tracking” to prove the testator was too medicated to have animus testandi (testamentary intent).
2. Undue Influence (The “Procurement” Red Flag)
I worked with a client, James, whose 81-year-old father, a retired dentist, left his $4.2 million estate to a caregiver he’d known for only six months. The will disinherited James entirely.
The “smoking gun” was Procurement. We proved the caregiver:
- Isolated the father from James.
- Chose the new drafting attorney herself.
- Paid the legal fees from the father’s account.
- Was present in the room during the signing.
James won a 60% settlement because we proved the will was an “act of capture,” not an act of love. [American Bar Association (ABA)]
3. Fraud or Forgery
This requires proving the testator was either tricked (Fraud in the Execution) or that the signature is a fake. In 2026, this increasingly involves Forensic Document Examiners who analyze “pen pressure” and digital metadata if the will was executed via Remote Online Notarization (RON).
4. Improper Execution
Every state has strict rules. Generally, a will must be in writing, signed by the testator, and witnessed by two “disinterested” parties. If the witnesses are also beneficiaries, the will is often voided under the Uniform Probate Code.
Step 3: The Machinery of Discovery (Why it Costs $100k+)
Most people think a will contest is a single day in front of a judge. It isn’t. It is an 18-month “Discovery Phase” where your attorney’s retainer vaporizes.
Expect your legal team to issue:
- Interrogatories: Written questions the defense must answer under oath.
- Subpoena duces tecum: Orders for medical records, bank statements, and cell phone logs.
- Depositions: Face-to-face questioning of the caregiver, witnesses, and the drafting attorney.
The Price of War:
Discovery alone accounts for roughly 60% of the total cost of estate matters. If you aren’t prepared to spend $40,000 – $80,000 before even reaching a trial date, do not start this process.

It distills the core action question, highlights the financial tradeoffs, and underscores how probate disputes can permanently damage family relationships while consuming a large share of the inheritance in legal fees.
| Pillar | Action Question | Reality Check |
|---|---|---|
| Proof | Do you have subpoenas for medical logs or other hard evidence? | Suspicions are not evidence; without a clear path to admissible proof, your case is likely to fail. |

How long does a will contest take in 2026?The average timeline from filing a petition to resolution (settlement or trial) is currently 14 to 22 months, depending on the complexity of the discovery phase. What is the success rate of will contests?While only 3% of oral wills succeed, formal will contests have a higher success rate—primarily because they end in settlements rather than “wins” or “losses” in court. Do I have to pay my lawyer upfront?Most probate litigators require a retainer ($5,000 – $15,000). While some take cases on a contingency fee basis, they usually only do so if the estate is valued at over $1 million and the evidence of procurement is “airtight.” Final Takeaway: A Battle of Head, Not Just HeartThe discovery of an unjust will is a deeply emotional experience. But the decision to contest it must be a cold, calculated one. Your feelings of being wronged are valid, but they are not evidence. Assess your case with cold calculation, and you will make the right decision for your future. Does the potential inheritance justify the very real cost?
