You can stop probate by entering a Caveat at the Probate Registry. This prevents a Grant of Probate from being issued for six months, giving you time to investigate potential invalidity, fraud, or lack of capacity. This is a critical first step for anyone questioning a Will’s authenticity.

The Caveat: Your Legal “Emergency Brake”
In the world of estate litigation, timing is everything. Once a Grant of Probate is issued, the executors have the legal authority to liquidate assets, sell property, and distribute funds. For “The Skeptic,” this is the point of no return.
A Caveat acts as a legal “stop notice.” It informs the court that the Will is being challenged and that the estate should not be unsealed. As validity specialists, we view the Caveat as the most powerful tool in your initial arsenal; it shifts the power balance back into your hands by pausing the clock.

When Should You Stop Probate?
Stopping probate is not a decision to be taken lightly, but it is necessary if you suspect:
- Lack of Testamentary Capacity: The deceased did not understand what they were signing due to dementia, illness, or medication.
- Undue Influence: A third party coerced or pressured the testator into changing their Will.
- Fraud or Forgery: The signature is suspect, or the document has been tampered with.
- Improper Execution: The Will was not witnessed or signed in accordance with the Wills Act 1837.
The Mechanics of Entering a Caveat
In 2026, the process for entering a Caveat remains streamlined but requires precision. You can submit an application via the HMCTS online portal or by post.
- Cost: The fee is currently £3.
- Duration: A Caveat lasts for six months.
- Renewal: You can renew it for further six-month periods, provided you do so before the current one expires.
Once the Caveat is in place, the Probate Registry will not issue a Grant to the executors without notifying you first.
The Investigation Phase: Use Your Time Wisely
Stopping probate is only the beginning. The six-month window provided by a Caveat is designed for Investigation, not just delay. During this time, a Validity Specialist will typically:
- Submit a Larke v Nugus Request: This demands the drafting solicitor’s file and attendance notes.
- Gather Medical Records: We analyze the testator’s health at the time the Will was signed.
- Interview Witnesses: We speak to the people who were present during the execution of the document.
What Happens if the Executor Challenges Your Caveat?
If the executors believe your Caveat is groundless, they can issue a “Warning.” This is a formal notice telling you that you must either “enter an Appearance” at the Probate Registry or let the Caveat lapse.
Warning: This is the “High-Stakes” Nodal Point. If you enter an Appearance, the Caveat becomes “permanent” until the dispute is resolved by a court or by agreement. However, once you enter an Appearance, you may become liable for legal costs if the court later finds your challenge was meritless. This is where professional guidance becomes indispensable to ensure you are not walking into a personal liability trap.
The Risk of Waiting Too Late
If you wait until after the Grant of Probate is issued, your legal path becomes significantly more difficult. You would have to apply to the court to “revoke” the Grant, a process that is far more expensive and legally burdensome than simply entering a Caveat.
As we move through 2026, the Probate Registry’s digital systems are faster than ever. If you have a suspicion, you must act before the “Grant of Probate” status on the public register changes to “Issued.”
Hold the Line
Stopping probate is the first line of defense for those who suspect foul play. It ensures that the estate remains intact while the “Validity Specialist” uncovers the truth behind the document’s creation. By entering a Caveat, you are telling the executors, and the court, that the truth matters more than administrative speed.

The Cost of Hesitation: The “Pre-Grant” Priority
In the landscape of 2026 probate, the window between application and the issuance of a Grant is narrowing due to increased automation at the Probate Registry. For the Validity Specialist, this means that “The Skeptic” must treat the pre-grant period as a critical forensic opportunity. Once the Grant is issued, the executors gain the “Shield of Authority,” allowing them to move funds beyond the reach of the court’s immediate oversight.
By failing to stop probate via a caveat, you are essentially allowing the opposing side to use the estate’s own resources to fund their defense against you. Stopping probate doesn’t just buy time; it preserves the status quo and ensures that the assets you are fighting for remain within the jurisdiction of the court rather than being dissipated by an executor whose authority you intend to challenge.

FAQs
Q1: Can I stop probate if I just think the Will is “unfair”?
Technically, you can enter a caveat for any reason, but using one purely to negotiate an Inheritance Act claim (where you admit the Will is valid but want more money) is considered an abuse of process. If the executors “warn” your caveat and you cannot show a genuine challenge to the validity of the document (such as fraud or lack of capacity), you could be ordered to pay the estate’s legal costs. For “unfair” Wills, you should instead seek a “standing search” and prepare a claim for financial provision.
Q2: How long does it actually take to stop probate once I apply?
In 2026, online caveat applications are processed almost instantaneously by the HMCTS system. Once the fee is paid and the digital form submitted, a block is placed on the probate record. However, it is vital to apply before the Grant has been signed by the registrar. If the Grant is issued even an hour before your caveat is processed, the caveat will not be effective, and you will be forced into the much more expensive territory of applying for a “Revocation of Grant.”
Q3: What happens if the six months runs out and I’m still investigating?
A caveat is not a “one-time” tool. You can renew it for a further six months as many times as necessary, provided the renewal application is made within the final month of the current caveat’s lifespan. As your Validity Specialist, I recommend setting a calendar alert for the five-month mark. If you miss the renewal window and the executors are quick, they can slip a probate application through the gap, instantly dissolving your ability to freeze the estate.
