A will dispute may concern signing formalities, capacity, knowledge and approval, undue influence or whether a later will exists. Identify the suspected issue before treating disappointment with the inheritance as proof that the will is invalid.
Preserve the making of the will
Locate the original and earlier versions, correspondence with the drafter and the identities of witnesses. Record what is known about instructions, execution and the deceased person's circumstances at the relevant time. Distinguish your observations from family reports and retrospective assumptions.
Medical or drafting records may need to be requested through an appropriate process. Do not alter the will, remove attachments or obtain confidential records by impersonating the deceased.
Match the protective step to the claim
In England and Wales, a caveat can stop a grant being issued while certain probate concerns are addressed. It has its own rules and is not a universal method for every inheritance complaint. [1] A claim for financial provision and a challenge to validity may involve different remedies and deadlines.
Seek advice promptly, stating whether a grant has already issued or assets are being distributed. Executor disputes should be distinguished from validity questions; uncertain beneficiary information may explain an apparent discrepancy without establishing wrongdoing.
Identify the document and the disputed event Write down which will or codicil is in question and obtain the best available copy without interfering with the original. Note its date, the named drafter and where it was found. If several versions exist, arrange them chronologically and record their source. A later date may be significant, but it does not by itself resolve validity. Tell the adviser whether the concern relates to instructions, signing, a particular amendment or an apparent change in who benefits, so the enquiry can be directed at the relevant event.
Describe what you personally observed separately from information received after the death. A witness who attended the signing may address a different issue from a neighbour who saw the deceased months earlier. Record approximate dates honestly when exact ones are unknown. Avoid asking witnesses to adopt a legal conclusion such as lack of capacity or undue influence. Their own account of conversations, behaviour and circumstances is more useful than a shared narrative created through repeated group discussions about what everyone believes must have happened.
Preserve the making file without altering it Keep envelopes, attachments, handwritten notes and electronic correspondence in their existing form. If photographs or scans are made, retain a record of who made them and when. Do not add explanations directly onto an original will or remove a staple to improve a scan. Give the adviser any information about damage or missing pages. An innocent change in physical condition can otherwise create an additional question that distracts from the issue the family originally wanted investigated.
Ask how relevant professional or medical records can lawfully be requested. Different records may involve different confidentiality and access rules, and possession of a death certificate does not necessarily entitle every relative to the full file. Identify the practitioner, dates and reason the material may matter. Preserve records already lawfully held, including appointment correspondence and the deceased's own messages. The purpose is to obtain reliable evidence about the relevant time, rather than assembling every health or family document regardless of its connection to the will.
Assess urgency against the grant position Find out whether a probate application has been made, whether a grant has issued and whether distribution is planned. The England and Wales probate search service can help establish the public record, although a recent grant may not appear immediately. [2] Tell the specialist about any imminent sale or payment. A request for information and a formal protective step have different effects, so do not assume that an unanswered letter to the executor prevents the administration from continuing.
Discuss whether a caveat is appropriate to the actual dispute. HMCTS describes caveats for issues such as entitlement to apply or whether a will is valid, and warns of possible proceedings and costs. [1] A complaint about the size of an inheritance, an executor's conduct or financial provision may require a different route. Ask about the response required if a caveat is challenged and the dates that must be monitored. Filing something without understanding its purpose can create a separate procedural problem.
Prepare a proportionate first instruction Give the adviser a short chronology, document list and explanation of the outcome sought. Identify missing evidence and any alternative explanation that should be considered. For example, a substantial change may follow a documented reconciliation or earlier lifetime support; that possibility should be assessed alongside concerns about pressure. Ask which enquiries are likely to clarify the issue and what they will cost. An initial evidence review can help distinguish a reason to investigate from a conclusion that a challenge will succeed.
Keep communications factual while the issue is examined. Do not publish allegations about relatives or the drafter on the assumption that publicity will preserve the estate. Record any agreement about temporary administration arrangements and its limits. If advice changes after new evidence is obtained, retain the revised assessment and review the next step promptly. The aim is a claim or resolution based on the actual grounds and evidence, with relevant deadlines considered separately, rather than a prolonged exchange of accusations that leaves the estate position uncertain.
Frequently asked questions
Does an unequal inheritance prove that the will is invalid?
No. The will's validity depends on relevant legal grounds and evidence. Disappointment with its distribution may raise a different question for advice.
Should witnesses discuss and agree their memories before speaking to a solicitor?
They should preserve their own recollections independently. A shared account can obscure what each person actually saw or heard at the relevant time.
Can a caveat solve every dispute about an estate?
No. Its purpose concerns particular probate issues. Financial provision, administration misconduct and other disputes may require different remedies and time-limit assessments.
Why preserve an envelope or damaged page with the will?
Physical context can help explain where the document came from and its condition. Altering it may create avoidable uncertainty about the evidence.
What should I disclose if assets may be distributed shortly?
Tell the adviser the proposed transaction, date, grant position and source of your information so any appropriate urgent step can be assessed.
