For a person’s own will, Banks v Goodfellow remains the relevant framework, distinct from the Mental Capacity Act test used for statutory-will jurisdiction. Blended families, estrangement and unequal provision make clear instructions and a careful record useful, but do not prove incapacity or automatically require an enhanced report. ## What counts as a complex family situation The situations that most often call for careful capacity evidence include second marriages and blended families where a spouse and children from an earlier relationship both hold expectations of the estate, estrangement where a child is excluded or left significantly less than others, unequal provision where one child has been a carer or where a family business or farm cannot sensibly be divided, late changes to a settled will following a diagnosis, bereavement or new relationship, and concerns about pressure from within the family where someone close to the person stands to benefit from the change. ## Complexity is not incapacity None of these situations means the person lacks capacity. Most testators in complex families have full capacity and simply hold difficult, sometimes unpopular, intentions, and the law protects their right to dispose of their estate as they choose. The assessment exists to evidence that choice, not to police it, and a person's decision to exclude a child or favour one branch of the family is not, of itself, evidence of anything except a decision someone may later dislike. ## Why complexity raises the evidential bar Banks v Goodfellow requires understanding of the will and its effects, the broad extent of property, appreciation of relevant claims and consideration of any disorder influencing the disposition in the legally relevant way. Explore the family context neutrally and record useful explanations. Hughes v Pritchard makes clear that a testator does not have to justify a change or give reasons to prove capacity; an unequal or unpopular will is not itself a failure of the test. ## The golden rule and contemporaneous evidence For an elderly or seriously ill testator, the Golden Rule recommends that a medical practitioner examine and record capacity and understanding and witness and approve the will. It is good practice, rather than a guarantee of validity. The solicitor should consider the appropriate medical input and retain detailed contemporaneous notes of the person’s instructions and reasons. ## What a robust assessment covers Ground the opinion in the actual will, estate and people with possible claims. Apply each limb of Banks v Goodfellow, recording the person’s own explanation and relevant medical or other evidence. Give appropriate communication support and distinguish unpopular wishes from disorder affecting the testamentary disposition. Do not replace the common-law test with a generic section 3 checklist or assume that family conflict is itself evidence of incapacity. ## Where undue influence concerns exist Capacity and undue influence are distinct. An assessor can document the person’s private account, observed interactions, dependence and other reported concerns, with sources clearly identified. Whether a will was procured by undue influence is ultimately for the court. Discuss with the solicitor what additional safeguarding, independent advice or evidence is needed rather than assuming a particular commercial assessment tier resolves the concern. ## Choosing a provider for a complex case For a will that is likely to be scrutinised, look for independence from every branch of the family, direct experience of disputed wills and retrospective work, contemporaneous record keeping and a report written to withstand challenge as opposed to one written to file. Ask whether an enhanced tier is available where a challenge is foreseeable, and expect the provider to work alongside the instructing solicitor so the assessment addresses the actual provisions being made. ## Timing the assessment Ideally the assessment sits alongside the giving of instructions, so that it addresses the will actually being made rather than a hypothetical one. Capacity is assessed at the material time, so fluctuating presentations need careful timing and documentation, and where a will has already been executed and is now in dispute, a retrospective testamentary capacity assessment addresses the historic decision from records and accounts. ## Key takeaway Apply the correct test to the actual will, record the person’s reasons and the supporting evidence, and keep questions of pressure and other validity requirements distinct. A detailed contemporaneous record can assist a later court, but cannot prevent a challenge or guarantee that the will is upheld. ## Frequently asked questions ### Does a complex family mean my relative will fail the capacity test? No. Family complexity does not change the Banks v Goodfellow test or establish a capacity conclusion. Identify the salient property and possible claims, support the person’s understanding and consider the evidence for the actual will. Do not presume either capacity or incapacity from how the family is organised. ### Can an assessment stop the will being challenged? No assessment can prevent a challenge or guarantee its outcome. A reasoned contemporaneous opinion may assist the court alongside the solicitor’s notes, witness evidence and records. Its weight depends on its quality, relevance and the other evidence. ### Should the assessment happen before or after instructions are given to the solicitor? Coordinate evidence with the solicitor while the instructions and proposed will are clear, and consider whether anything material has changed by execution. If presentation fluctuates, choose supportive timing and record the dates, sources and limitations. Medical input under the Golden Rule is a separate consideration from a general specialist report. ## Related mental capacity assessment pages The related pages below explain connected decisions, evidence requirements and legal processes. ### Testamentary Capacity Assessment ### Banks v Goodfellow and the test for making a will ### Undue influence and testamentary capacity assessments ### Read guide ## Practical next steps Before seeking a report, write down the exact decision, relevant date, reason for concern and intended use. Gather the documents that explain the real options and any communication needs. Check any required form or court direction, agree the scope and total fee, and clarify how missing evidence or further questions will be handled. ## Primary sources and official guidance [Mental Capacity Act 2005](https://www.legislation.gov.uk/ukpga/2005/9/contents) [Mental Capacity Act Code of Practice](https://www.gov.uk/government/publications/mental-capacity-act-code-of-practice) ## Related information - [Mental Capacity Assessment to Revoke a Lasting Power of Attorney](https://www.nelliesupports.com/lasting-power-of-attorney-services/revoke-lpa) - [NHS Continuing Healthcare Support](https://www.nelliesupports.com/services/continuing-healthcare) - [CHC Appeal Application: Drafting and Submission](https://www.nelliesupports.com/services/continuing-healthcare/chc-appeal-application) --- Nellie Supports Ltd · 0333 987 5118 · nellie@nelliesupports.com Office 11 and 12, Unit 20, Springfield Business Park, Grantham, NG31 7FZ
