When Should You Mediate a Probate Dispute?
Mediation may help resolve a probate dispute, but it is not always the most economical first intervention. Sometimes the missing step is a valuation, disclosure of accounts or a properly framed proposal. Before booking a mediation, identify the issue, the evidence needed and who can make the decisions. This guide helps you consider the appropriate next step for an estate in England and Wales.

Identify what you want the discussion to achieve
An estate dispute may concern a will’s validity, a proposed property sale, estate accounts, an executor’s conduct or a claim for financial provision. Describe the specific disagreement and the practical result sought. “We cannot get on” is understandable, but it gives a mediator less to work with than an identified decision about a sale, payment or disputed transaction.
The independent mediator facilitates discussion; they do not decide who is legally right or give either party individual legal advice. Your own adviser can assess your position and a proposed compromise. Mediation does not require you to accept a settlement you consider unsuitable. [1]
Establish enough evidence to negotiate sensibly
You do not need to resolve every factual disagreement before mediation. You do need enough information to understand the important uncertainties and the consequences of an agreement. Depending on the issue, that may include the will and grant, selected accounts, valuations, key correspondence or evidence supporting a challenged transaction.
Where a missing record is central, a targeted information request may be the better immediate step. Conversely, insisting on complete agreement about every historical detail can postpone useful discussions indefinitely. Advice should distinguish information needed for a responsible decision from material that would add cost without changing it.
Consider a narrower negotiation first
Direct negotiation or solicitor correspondence may be sufficient where the issue is limited and the relevant information can be exchanged. For example, two executors disputing a sale price might first agree a process for obtaining and considering valuation evidence.
Mediation may be more useful where several issues interact, communication has broken down or the parties need help exploring a package of terms. A dispute centred on a narrow legal question may instead justify advice about early neutral evaluation. The process should fit the problem rather than be selected simply because correspondence has become exhausting.
| Situation | Possible next step |
|---|---|
| Key estate accounts or valuations are missing | Targeted information exchange |
| The parties disagree on one manageable issue | Direct negotiation |
| Several connected issues need a package of terms | Consider mediation |
| A narrow legal question is preventing progress | Consider early neutral evaluation or specialist advice |
| A procedural deadline or urgent asset risk exists | Obtain urgent legal advice and assess protective action |
These are starting points, not automatic recommendations. The appropriate route depends on the evidence, urgency and parties involved.
Identify everyone whose involvement is needed
Check who must participate and who can approve the proposed terms. An executor cannot necessarily compromise every beneficiary’s rights simply by attending. Consider all affected interests, including trusts, minors, people who lack relevant capacity and beneficiaries who are missing or cannot be identified.
Specialist representation or court approval may be necessary. CPR 21.10 concerns the settlement of claims by, on behalf of or against a child or protected party. Within that scope, court approval is required, including for relevant agreements reached before proceedings. Not every estate arrangement affecting a minor falls under that particular rule; other representation or approval requirements may still need consideration. [2]
Discuss accessibility, communication needs and any intimidation or power imbalance with the mediator and your adviser. Separate rooms or an online format may help some participants, but adjustments do not make every case suitable.
Obtain a budget for the whole exercise
Ask for the mediator’s fee, preparation requirements, session length, cancellation terms and charges if discussions run over. Obtain separate figures for your solicitor’s preparation, attendance and settlement drafting, and for counsel or valuation evidence if needed. Establish whether VAT and other expenses are included.
Identify who is responsible for payment. Do not assume the estate will bear every participant’s costs or that a settlement will produce reimbursement. Compare the proposed expense with the issue at stake, continuing delay and the work that might remain afterwards.
Keep deadlines and protective steps under review
Mediation discussions do not automatically stop limitation periods, extend a caveat-warning response date or vary a court timetable. Identify who is responsible for any protective action and obtain advice promptly. If proceedings are under way, the court’s timetable continues unless appropriately changed.
The civil courts can order parties to engage in ADR. Failure to comply with an ADR order, or unreasonable failure to engage, may affect costs. That does not mean every probate disagreement requires mediation or that attendance guarantees settlement. The appropriate response depends on the facts and any directions. [3]
Record any agreement properly
Discuss in advance who will draft terms and advise before they are accepted. Cover the obligations, payments, dates, costs, any releases, implementation steps and necessary approvals. A property agreement may need conveyancing or other formal work afterwards. Do not assume the mediator’s involvement alone completes every legal step.
Mediation discussions are generally confidential and often protected by without-prejudice privilege, but those protections are not absolute. The mediation agreement and applicable law matter. Obtain advice about what can be shared, the status of proposed terms and when any settlement becomes binding. [1]
If agreement is not reached
The next step is not automatically a court claim. Consider whether the issues have narrowed, further evidence could assist or later negotiation is worthwhile. Assess any offer with your adviser and preserve applicable confidentiality. Where an urgent remedy or binding determination is needed, separate litigation advice may be appropriate.
Assess the next step with Justin
Human Law’s Stage 01 review costs £480 including VAT (£400 + VAT). Justin reviews up to 40 selected core pages concerning one principal issue, holds a 30-minute consultation and provides a two-page Action Plan. It may identify further information, negotiation, mediation preparation or specialist litigation advice as the proportionate next step.
This is advice to the instructing client, not an appointment as an independent mediator. Mediation attendance, further correspondence and settlement drafting are not included in Stage 01 and require separate agreement if offered. There is no obligation to continue. The free ADR preparation questionnaire can help organise your questions; it does not assess merits or replace legal advice.
