When a Probate File Becomes Contentious
A routine estate administration can encounter a dispute without the entire file needing to move to another practice. The first task is to identify the legal obstacle, check immediate risks and decide which work your practice can safely retain. This guide is for non-contentious probate solicitors and accountancy probate teams in England and Wales.

Identify the decision that has become blocked
Start with the act, information or decision preventing progress. Is a caveat stopping the grant? Are co-executors unable to agree a sale? Is a beneficiary asking for missing accounts, challenging an entry or alleging a breach of duty? These situations require different assessments. A long correspondence file does not, by itself, identify the legal problem.
Write a short statement of the obstacle, the relevant grant position and what would allow administration to continue. Separate established facts from allegations and record the evidence still needed. This gives the client and any external adviser a usable starting point.
Assess the substance, not the tone, of correspondence. An angry letter may add little; a measured one may identify a serious issue or deadline. Before drafting again, state the decision or information the response should obtain.
Check urgency before considering a referral
Check for issued proceedings, formal service, a caveat warning, limitation dates, threatened distribution and immediate risks to assets. A routine file review is not a substitute for urgent advice or a protective step. Do not assume that settlement discussions suspend a deadline.
Record who is responsible for each live deadline while any referral is considered. Sending an enquiry or a bundle does not establish that another practitioner has accepted responsibility. The referring practice remains responsible for work within its existing retainer unless and until a transfer or other change is expressly agreed. Confirm the receiving practitioner’s acceptance of the particular task and any urgent deadline.
Revisit the client and the capacity in which advice is needed
Identify who your practice represents and whether the instructions concern estate administration, an executor’s personal exposure or a beneficiary’s claim. A person who is both executor and beneficiary may have different interests in those capacities. Do not assume that all family members are clients or that everyone’s interests remain aligned.
Solicitors must assess conflicts and confidentiality before acting or sharing information. Where a complaint concerns the practice’s own work, assess the potential own-interest conflict, independent advice and any insurer-notification requirements. A mistake does not automatically prevent continued acting, but specialist input does not itself cure a conflict. SRA guidance on putting matters right. Accountancy probate teams should apply their own regulator’s requirements and the limits of their authorisation. [1]
Choose the level of additional support
Three routes are worth considering, subject to your authorisation, competence and conflicts position. Your team may retain work it can properly handle. It may commission external advice on one defined issue while continuing appropriate administration work. Or the client may need a litigation practitioner to take responsibility for proceedings, urgent relief or substantial contested evidence.
For ICAEW-authorised probate practices, authorisation covers non-contentious probate only. If the probate matter becomes contentious, the practice must cease that regulated work and arrange an appropriate referral. Not every beneficiary complaint makes the probate application contentious. Assess the position rather than assuming either that all work must stop or that the whole administration can be retained. Other administration or accountancy work may remain possible, depending on authorisation, conflicts and the engagement. [3]
The choice should follow the work required. A discrete external assessment may help where an otherwise manageable file has stalled over legal uncertainty. It is less useful if immediate representation in proceedings is needed. Some disputes affect who can safely act, create conflicts or make continued administration inappropriate; the disputed work cannot always be separated from the wider retainer. Record why the chosen route is proportionate and revisit it as matters develop.
Five Reasons a Probate Dispute May End Before a Final Trial
A probate matter becoming contentious does not necessarily mean that it will proceed to a full trial. Some disputes are resolved through Probate Registry procedure, clarification of the evidence or agreement between the parties. Others require court involvement but conclude before a final trial.
1. Probate Registry procedure may address the immediate problem
Some disputes concern a specific procedural obstacle, such as a caveat preventing the issue of a Grant or uncertainty about who is entitled to apply. Identifying the appropriate Probate Registry procedure may allow that issue to be addressed without immediately commencing wider contested proceedings. This does not mean that the Registry routinely determines disputed allegations or the merits of a will challenge without the appropriate proceedings.
2. A caveat may expire, be withdrawn or be removed
An ordinary caveat may expire if it is not renewed, or the caveator may agree to withdraw it. Where a warning has been properly served and no Appearance or other permitted response is made within the applicable period, the person warning may take the prescribed steps to seek removal.
If an Appearance is entered, the position changes. The caveat cannot simply be treated as expiring in the ordinary way or withdrawn by the ordinary notice route; removal requires the appropriate order. Removing a caveat does not itself determine every underlying dispute. [5]
3. The evidence may change the parties’ assessment
Estate accounts, correspondence, testamentary documents or other records may answer an allegation, clarify what has happened or reveal weaknesses in a party’s position. Once the relevant evidence has been examined, a party may decide that pursuing the dispute is unnecessary or disproportionate.
4. The parties may reach an agreement
Focused correspondence, negotiation or mediation can sometimes resolve the disagreement before proceedings are issued. Settlement may also occur after proceedings have begun. Any agreement must be properly authorised and implemented, particularly where executors, trustees, beneficiaries or protected interests are involved.
5. Early judicial case management may encourage resolution
Where proceedings are necessary, early directions may clarify the issues, identify the evidence required and expose the likely cost and work involved. The court may encourage or, where legally appropriate, order alternative dispute resolution. This can prompt reassessment and settlement before a final trial, although judicial intervention does not guarantee agreement. A directions hearing is already court involvement; avoiding a final trial is different from avoiding court altogether. [6]
What this means for executors and professional advisers
The important first step is to identify the particular issue preventing progress, the evidence required and the appropriate procedural or negotiated route. These are possible routes to conclusion, not a statistical claim about how frequently disputes settle.
Human Law provides solicitor-led assessment and defined non-court assistance, with Probate Registry work separately agreed where appropriate. For accepted direct individual instructions, the Dispute Assessment & Action Plan costs £480 including VAT. Advice commissioned by a professional practice follows the separate Professional File Review arrangements explained below. Tell us what is holding matters up and we will quote a fixed fee for the work; the assessment is optional.
Where proceedings or specialist litigation representation are necessary, the appropriate referral should be identified promptly. Relevant procedural deadlines must be protected throughout. The possibility of resolution before trial does not change a practitioner’s authorisation limits or justify continuing work they are not authorised or competent to undertake.
Consider information exchange and settlement
Before commissioning another broad response, ask what it should achieve. A focused exchange of accounts, valuation evidence or the grounds of an objection may narrow the dispute. Negotiation may then address the remaining decision. Mediation can be considered where an independent facilitator could assist, but it does not remove the need to understand the evidence or obtain settlement authority.
The ACTAPS Code offers probate and trust dispute practice guidance on identifying claims, exchanging relevant material and considering ADR. It is not a mandatory CPR pre-action protocol and does not replace applicable rules, directions or deadlines. Its relevance depends on the dispute. [2]
Record what the evidence currently supports, realistic alternatives and which missing or disputed facts could change the advice. Reassess when the record changes. Test whether a proposed agreement leaves the estate able to progress through the next decisions, rather than recreating the same disagreement.
Document review and technology-assisted analysis
Where technology assists review, check which documents, attachments and pages it has actually processed. Trace material conclusions to the originals, test competing explanations and verify legal propositions against current authoritative sources. Use approved systems with appropriate confidentiality and data safeguards. Justin remains responsible for his analysis and recommendations; the referring adviser remains responsible for decisions and work within its own role.
Agree responsibility and costs before sharing the file
An external instruction should identify the client, fee payer, permitted recipients of the advice, included documents and deliverable. Confirm who communicates with the other side, who deals with deadlines and which administration tasks remain with your team. Address confidentiality, privilege and authority for disclosure before sending substantive papers.
Distinguish advice commissioned for the practice itself from outsourced work on its client’s matter and a direct client referral. A fee-payer or contractual client label does not determine all professional duties. When one solicitor firm outsources part of a client matter to another, the originating firm retains responsibility and both firms may owe client-care duties to the underlying client. Obtain the client’s consent to outsourcing or referral and the necessary authority to share confidential information. [4]
Explain the additional fee alongside the likely continuing administration costs. A fixed fee gives certainty for its stated scope; it is not automatically an overall cap. Solicitors must provide appropriate information about likely overall costs and update it as matters progress. Whether fees can properly be borne by the estate needs separate consideration; an external instruction does not itself establish that entitlement. [1]
Communication and complaints during a dispute
A family dispute and a service complaint are different issues; both may need attention. Record the concern, explain progress and delay, identify the next action and review date, and address service dissatisfaction through the appropriate complaints procedure. A specialist referral does not replace complaint handling or guarantee that complaints will be avoided.
What the published complaints evidence shows
The Legal Ombudsman accepted 1,128 wills and probate complaints in 2024/25, up 28%, and 1,147 in 2025/26, approximately 1.7% higher. Within the latest broader category, probate complaints fell 3%, while will-drafting and power-of-attorney complaints rose. These figures do not establish a continuing rise specifically in inheritance-dispute complaints, or a higher complaint rate per matter.
Its probate spotlight identifies communication difficulties and recognises that providers may be unfairly accused of taking sides. Distinguish the merits of an allegation from whether a reasonable request or service complaint has received a proper response.
The SRA probate review notes that the Legal Ombudsman can consider beneficiary complaints even where the beneficiary is not the firm’s client, and recommends using the internal complaints process. The service owed is not identical to that owed to a client. Accountancy practices should apply their own regulator’s and applicable complaints-scheme requirements; the figures above do not establish a separate trend for accountants.
Plan the return to ordinary administration
Agree what marks completion. The handback should state the issue assessed, advice or action delivered, unresolved questions, relevant deadlines and the person responsible for the next step. If court representation is required, identify the receiving practitioner’s acceptance and the limits of any interim involvement.
Record the decision, evidence relied upon, alternatives considered and next review point. A short handback record helps prevent two advisers duplicating work or each assuming the other is acting. The aim is a clear division of responsibility that lets the administration continue wherever that remains appropriate.
Defined support from Human Law
The Professional File Review costs £1,020 including VAT (£850 + VAT). It covers one principal blockage, up to 60 selected core pages, a 30-minute consultation with the responsible fee-earner and written recommendations. Unlike a preliminary referral discussion, this is a defined advisory instruction resulting in recommendations the practice can use to decide how the administration should proceed.
Human Law’s role is limited to the agreed issue, without taking over the underlying administration. The engagement confirms who is instructing, who may rely on the advice and whether the work is advice to the practice or outsourced advice on its client’s matter. Retaining the administration remains subject to the practice’s authorisation, conflicts position and continuing duties.
A separate direct referral means the executor, administrator or other accepted individual instructs Human Law as its client; confidentiality and information sharing must be agreed accordingly. Further work is separately scoped and priced. See the Professional File Review page for service boundaries and the Professional Referral Guide for arrangements. Send a brief outline and any deadline before substantive documents.
