When late-stage wills are manipulated or powers of attorney used to drain family wealth, passive mediation guarantees financial distress.
In Jersey’s high-value offshore economy, disputed testaments directly threaten generationally accumulated wealth held across premium real estate, international banking lines and complex corporate structures.
Whether you face a will drafted under suspicious circumstances, overt coercion or an attorney systematically stripping a vulnerable relative’s estate, stalling in negotiation gives bad-faith persons the exact window needed to dissipate assets.
We deliver resolute, trial-ready courtroom advocacy to crush predatory inheritance theft, invalidate fraudulent mechanisms and protect your capital.
Dismantle fraudulent will changes, block toxic powers of attorney, and lock in your true inheritance rights.
Secure a Will & LPA Assessment
The Cost of Testamentary Delays
Standard offshore law firms approach contested probate and capacity disputes with a detached, administrative mindset.
They treat profound estate manipulation and financial elder abuse as routine clerical issues.
This traps your commercial interests in endless loops of polite, defensive correspondence with suspect executors, bleeding core capital through cross-border dissipation while billable hours accumulate.
At Sinels, we treat contested wills and Lasting Power of Attorney (LPA) overreach as high-stakes litigation.
Led by Philip Sinel, our advocates operate with a disciplined strategy that prepares for trial from the outset. We identify medical and legal vulnerabilities in the opposition’s file, target rogue executors and self-serving attorneys, and deploy rapid interim remedies.
By lodging immediate caveats at the Jersey Probate Registry and executing emergency freezing injunctions in the Royal Court of Jersey, we halt unauthorised distributions to protect your legacy.
Our Strategic Litigation Framework
Testamentary Capacity & Will Validity Challenges
We litigate high-stakes challenges against the validity of wills encompassing movable and immovable estates under the Wills and Successions (Jersey) Law 1993.
Our advocates target lack of capacity, fraudulent inducement and critical execution defects. By moving instantly to gather contemporaneous medical files, financial timelines and witness statements, we systematically deconstruct manipulated testaments.
This methodical approach allows you to invalidate predatory wills, restore your legitimate statutory rights and securely lock down the estate asset pool.
Lasting Power of Attorney (LPA) Abuse & Revocation
We prosecute and defend actions under the Capacity and Self-Determination (Jersey) Law 2016 concerning the abuse of property, financial affairs, or health and welfare powers.
We can launch rapid applications before the Royal Court under Article 19 to determine the validity of the LPA instrument, compel forensic accounting of all transactions and strip rogue attorneys of their authority. This decisive action permanently neutralises predators exploiting cognitive decline, protects the donor’s core assets and ensures the recovery of misappropriated family capital.
Contentious Probates
Not every estate dispute begins with a challenge to the will itself. Contentious probate covers the wider category of disagreements that arise once someone has died, an executor who will not account for what they have done, an estate distributed to the wrong people, assets that have quietly left the estate before it was ever valued, or beneficiaries left without answers while administration stalls for years. We act for beneficiaries who cannot get a straight answer out of an executor, and for executors facing accusations they consider unfounded. Our approach is the same either way: establish the facts and the paper trail first, apply to the Royal Court where an executor needs to be removed, compelled to account, or replaced, and resolve the matter without a trial wherever that can be done from a position of strength.
Emergency Caveats & Asset Freezing Injunctions
We deploy immediate, heavy-hitting interim relief to halt the administration of a disputed estate or the transfer of liquid wealth. By lodging formal caveats with the Jersey Probate Registry, we can entirely block the issuance of a Grant of Probate. Additionally, we secure ex parte freezing orders against suspect bank accounts without warning. This maintains total tactical supremacy over the asset structure, preventing bad-faith executors or attorneys from dispersing, spending or moving capital offshore while the litigation is fought.
Why High-Net-Worth Heirs and Beneficiaries Instruct Sinels
Sinels is a dedicated litigation practice with a thirty-year history of winning Jersey’s most demanding family wealth, trust and contentious probate battles.
We operate entirely free from the institutional conflicts of interest that prevent large, full-service offshore practices tied to major private banks, dominant trust corporations or wealth managers from acting. We do not produce passive advisory notes or recommend low-value compromises. Instead, we build the evidence, take the points that are actually available, and are ready to run the matter to a hearing if it comes to that.

Frequently Asked Questions About Contesting Wills & LPAs
What is the legal test for testamentary capacity in Jersey?
Jersey applies the established common-law test from Banks v Goodfellow.
The court evaluates whether, at the precise moment of execution, the testator understood the nature and effect of making a will, the general extent of the property being disposed of, and the claims of individuals who might reasonably expect to inherit.
A medical diagnosis of cognitive decline or dementia does not automatically negate capacity, as the legal threshold is time- and task-specific.
We use retrospective expert medical analysis to litigate these boundaries before the Royal Court.
What immediate action can be taken to stop an executor from distributing a disputed estate?
You must act before a Grant of Probate is issued by lodging a formal caveat with the Jersey Probate Registry.
This acts as an absolute legal block, preventing the court from granting probate or letters of administration for a renewable six-month period.
This intervention stops executors from transferring or dissipating local funds or real estate, providing the necessary time to file a substantive challenge before the Royal Court.
How can a Lasting Power of Attorney (LPA) be challenged or revoked in Jersey?
An LPA can be challenged under the Capacity and Self-Determination (Jersey) Law 2016 if there is evidence the donor lacked capacity upon creation, or was subjected to undue influence or fraud.
If an active attorney abuses their position, any interested person may petition the Royal Court under Article 19.
The court has the authority to determine the validity of the document, revoke the attorney’s power or appoint an independent delegate.
