The Will That Changed Everything — Three Weeks Too Late to Ask About It
Robert Callahan had been a meticulous man his entire life. He spent thirty-one years as an electrical engineer at Texas Instruments, raised three children in Frisco, and paid off his home in the Starwood subdivision long before his neighbors had. His will — drafted in 2018 with an estate planning attorney in McKinney — divided his estate equally among his children: Marcus, Diana, and Paul. Three shares. No favorites. The kind of document a careful man makes when he still has time to think.
By the spring of 2025, Robert no longer had time to think about much. He had been diagnosed with pancreatic cancer in January. By February, he was on a palliative care protocol that included high-dose opioids for pain. By early March, he required help bathing, dressing, and moving from his bedroom to the kitchen. Paul, the youngest, had moved back into the house the previous summer to manage medical appointments and household logistics. Marcus lived in McKinney and visited on weekends. Diana was in Colorado and traveled back twice during the final months.
Twenty-two days before Robert died, he signed a new will.
The new document — drafted by an attorney Paul had located and scheduled the appointment with — left 80 percent of the estate to Paul and 20 percent split between Marcus and Diana. It was witnessed by two men from Paul's workplace. Robert's estate, including the Starwood home, retirement accounts, and a brokerage portfolio, totaled approximately $2.1 million. Under the 2018 will, each child would have received roughly $700,000. Under the new will, Marcus and Diana together would receive $210,000.
Six weeks after Robert died, Marcus and Diana retained a probate litigation attorney and filed a will contest in Collin County Probate Court.
What follows is not the story of whether Marcus and Diana were right. It is the story of what their attorney told them the law requires — and what it means for every North Texas family facing the possibility that something went wrong at the end of a loved one's life.
Collin County's Growth Has Created a New Probate Reality
Collin County added more residents between 2010 and 2020 than almost any county in the United States. The growth didn't stop there: Frisco alone has grown from roughly 116,000 people in 2010 to nearly 240,000 today. McKinney, Plano, Allen, Prosper, and Celina have each expanded dramatically. The wealth that followed that growth — in home equity, retirement accounts, business interests, and investment portfolios — has created an estate environment unlike anything this part of Texas saw a generation ago.
Larger estates, combined with more complex family structures — blended families, estranged adult children, caregivers with outsized access to aging parents — produce more contested estates. Collin County's probate court now handles will contests, executor disputes, trust litigation, and heirship fights that reflect the full spectrum of what can go wrong when significant wealth is passed from one generation to the next.
What most families don't realize — until they are sitting across from an attorney with a question about a will they believe was manipulated — is that Texas law gives them meaningful legal tools to pursue those claims. And meaningful deadlines they cannot afford to miss.
The Grounds for Challenging a Will in Texas
A will contest in Texas is a formal legal proceeding filed in the probate court of the county where the will was admitted. Under Texas Estates Code § 256.204, a contest must be filed within two years of the date the court admits the will to probate. That two-year clock starts on the date of the court's order — not the date of death, not the date someone finds the will. Miss that window, and the challenge is barred regardless of what the evidence shows.
The grounds for challenging a will fall into four main categories:
1. Lack of Testamentary Capacity
Under Texas Estates Code § 251.001, a person must have "testamentary capacity" to make a valid will. That means they must, at the time of signing, understand: the nature and extent of their property; the natural objects of their bounty — the people one would ordinarily expect to inherit; what a will is and what it does; and how these elements relate to each other to form a plan of distribution.
The standard is not whether the person was confused or impaired on other days — it is whether they possessed testamentary capacity at the specific moment of signing. A person with dementia can have a valid will if they understood these elements during a lucid interval. A person on strong pain medication may lack capacity even if they seemed perfectly clear the day before.
In contested cases, medical records, nursing notes, hospice documentation, and testimony from treating physicians — sometimes supplemented by expert neurological or psychiatric opinion — form the evidentiary foundation of the capacity analysis. Courts weigh the whole picture, not just a single medical notation.
2. Undue Influence
Undue influence is the most commonly alleged ground in Texas will contests and the hardest to prove. The legal standard requires showing that the influencing party had a susceptible testator, had opportunity to exert influence, had a motive to do so, and actually overcame the testator's free will and independent judgment in making the will.
Persuasion alone — encouraging a parent to leave more to one child — is not undue influence. The law distinguishes between influence that is exerted and influence that has become coercive. Courts look at the totality of the circumstances: isolation from other family members, physical or cognitive vulnerability, financial dependency, the degree to which the accused party controlled access to the testator, and the suspicious timing or content of the change.
A will changed within weeks of death, witnessed by associates of the beneficiary who stands to gain the most, drafted through an attorney that beneficiary selected, and executed while the testator was in palliative care — those facts form the factual architecture of an undue influence claim. Whether they prove it requires investigation, discovery, and often trial.
3. Fraud and Duress
Fraud occurs when a testator is deceived — told false facts about family members, for example, to induce them to disinherit someone they otherwise would not. Duress involves coercion: threats, physical pressure, or denial of care to obtain a desired outcome. Both are distinct from undue influence, though the underlying facts often overlap and multiple theories can be pursued in the same lawsuit.

4. Improper Execution
Texas law requires a will to be in writing, signed by the testator, and witnessed by two credible witnesses who are not named beneficiaries. A will that fails these execution formalities is void. In self-proving wills — the standard modern form — the witnesses also sign an affidavit before a notary. A challenge to execution is often the most straightforward ground to prove or disprove: the document either meets the statutory requirements or it doesn't.
Beyond the Will: Executor Misconduct and the Duty to Beneficiaries
Even when the will itself is valid, litigation can arise from how the estate is administered. Once a will is admitted to probate and an executor is appointed, that executor holds a fiduciary position under Texas law. The executor owes beneficiaries a duty of loyalty, candor, and competent administration. Failure to meet that duty gives rise to claims for breach of fiduciary duty — and, in serious cases, to executor removal.
Under Texas Estates Code § 404.003, a probate court may remove an executor who has misappropriated estate funds, grossly mismanaged estate property, failed to make required accountings, or refused to file an inventory. The threshold is meaningful — courts do not remove executors for minor disagreements — but self-dealing, hiding assets from beneficiaries, or actively refusing to comply with court orders will meet it.
Executor removal proceedings happen separately from, and sometimes alongside, a will contest. A family that simultaneously challenges the validity of the will and the conduct of the person named as executor will often be pursuing both tracks of litigation at once.
What Probate Litigation in Collin County Actually Looks Like
Television has given most people a distorted picture of courtroom litigation — dramatic cross-examinations, surprise witnesses, verdicts reached in a single afternoon. Probate litigation in Collin County looks very different.
A contested estate typically begins with a petition filed with the Collin County District Clerk's Office, followed by service on all parties and a scheduling order that sets deadlines for discovery. Both sides exchange records: the decedent's complete medical chart, financial account statements going back years, communications between the decedent and all beneficiaries, the billing records and file of any attorney who drafted the disputed document, and cell phone or email records that illuminate who was communicating with whom during the final months of the decedent's life.
Depositions are taken — of the witnesses who signed the will, of the drafting attorney, of caregivers, of treating physicians, of anyone present at the signing. Expert witnesses — geriatric psychiatrists, forensic accountants, handwriting analysts — are retained to interpret the evidence for the fact-finder. Mediation is typically required before trial, and it resolves many cases without a verdict. Those that do not resolve proceed to a bench or jury trial that can run several days and cover evidence accumulated over a year or more of litigation.
The full process typically runs twelve to twenty-four months; complex cases can take longer. Attorney fees in contested estate matters are substantial. Neither of these facts is a reason not to pursue a legitimate claim — but they are facts every family should weigh clearly before filing.
Back to the Callahans in Frisco
Marcus and Diana filed their will contest within sixty days of probate. Their attorney subpoenaed Robert's complete medical records from Medical City Frisco and the hospice provider. The records showed that Robert had been prescribed fentanyl patches and oral morphine at doses that, according to the treating physician's own notes, "occasionally cause periods of confusion and reduced cognitive engagement." The attorney who drafted the new will was deposed and acknowledged that he had met Robert only once, that Paul had scheduled and attended the meeting, and that he had not conducted an independent capacity evaluation. The two witnesses — Paul's coworkers — confirmed in deposition that they had not spoken with Robert before or after the signing.
The case settled in mediation before trial. The terms are confidential, as most probate settlement agreements in Texas are. Whether the outcome reflected what Robert would have wanted — sitting at his drafting table in 1988, staring at blueprints for a semiconductor plant in Sherman — no one outside the family can say with certainty.
What Marcus and Diana understood by the time the mediation ended is that the law did not guarantee them the outcome they believed was fair. It gave them a process. A process that required evidence, deadlines, and attorneys who understood how Collin County's probate court actually works.
If Your Family Is Facing a Contested Estate in Collin County
Probate litigation is not the answer to every family dispute over an inheritance. Some disagreements reflect choices that were legally valid even if they were painful — a parent who chose to leave more to one child, for reasons that were theirs to make. But when there are real questions about a testator's mental state, about who controlled the environment in which a will was changed, or about how an executor is managing assets that belong to beneficiaries — those questions have legal answers, and the window to pursue them is not unlimited.
