Inheritance Dispute: Elderly Parent Suspects Family Member
Margaret was 74. She had given her daughter Carol power of attorney over her financial affairs so that Carol could help manage her accounts while Margaret's health was declining. When Margaret's other two children reviewed her bank statements, they found £22,000 in withdrawals they could not account for. Carol said the money had been spent on Margaret's care and household expenses. The accounts told a different story.
Important Privacy & Sensitivity Notice
Anonymisation: All names, family relationships beyond general terms, and identifying details have been fully anonymised. "Margaret," "Carol," and the other family members are not the subjects' real names.
Vulnerability: This case involved an elderly individual. The investigation was conducted with appropriate sensitivity to Margaret's age and health circumstances. The arrangement of the test through a solicitor ensured that Margaret's interests were protected throughout the process.
Consent: Carol provided full informed written consent before the session. The test was explained to her by both the solicitor and our pre-session briefing. She understood the nature of the investigation.
Purpose: This case study is published to help families, solicitors, and individuals dealing with suspected elder financial abuse understand how P300 EEG can be used in this specific context — and what the process and outcome involve.
Background
"Margaret" (anonymised, 74, South West England) had three adult children. Her health had been declining gradually since 2022 — nothing acute, but a slow accumulation of reduced mobility, fatigue, and increasing difficulty managing her daily administration. In early 2024, at Carol's suggestion, Margaret granted Carol a Lasting Power of Attorney (LPA) for financial affairs. Carol had been the most physically present of the three children, visiting weekly, accompanying Margaret to appointments, and managing her shopping.
Margaret's other two children — both living further away — had no reason to question the arrangement at the time it was made. Carol seemed devoted. Margaret seemed well cared for. The LPA was a practical response to a genuine situation.
In January 2026, Margaret's son requested access to her bank statements as part of preparing for an estate planning review with Margaret's solicitor. What the statements showed prompted the family to look more carefully at the accounts going back to when the LPA had been activated.
Over the 18 months since the LPA had been in effect, Carol had made withdrawals from Margaret's accounts totalling approximately £22,000 beyond what could be accounted for by Margaret's documented household expenses, care costs, utilities, and regular outgoings. The excess withdrawals — largely in cash — had no corresponding receipts, invoices, or records in Margaret's files.
When the family raised this with Carol, she stated that the money had been spent on Margaret's care and on household items that Margaret had asked for. She produced a partial list of expenses that accounted for approximately £4,800 of the total. The remaining £17,200 in unexplained withdrawals she attributed to cash purchases that had not been receipted, oral instructions from Margaret that she had acted on, and what she described as the general costs of managing an elderly person's needs that "don't always come with paperwork."
Margaret's solicitor arranged the P300 EEG investigation at Margaret's request. Margaret was clear about what she wanted: to know whether Carol had taken her money for Carol's own benefit, or whether the unexplained withdrawals genuinely reflected spending on Margaret's behalf that simply hadn't been documented.
The power of attorney context
Why LPA cases are particularly difficult to investigate by conventional means
A Lasting Power of Attorney for financial affairs gives the attorney (Carol) the legal authority to manage the donor's (Margaret's) financial affairs. All transactions made under the LPA are technically authorised — Carol had the legal power to make withdrawals from Margaret's accounts. The question is whether those withdrawals were made for Margaret's benefit, as the LPA requires, or for Carol's own benefit.
The difficulty is that legitimate LPA expenditure often includes cash purchases, informal arrangements, and spending that an elderly person would not reliably remember or document. Distinguishing between "genuinely spent on Margaret's behalf but not documented" and "taken for Carol's personal use and retrospectively described as care expenses" is a factual question about Carol's intent — exactly the kind of question that financial records alone cannot answer.
P300 EEG addresses this by testing whether Carol holds specific neurological knowledge of having used the withdrawals for her own benefit — knowledge that only someone who had taken the money for themselves would hold in this specific neurological form.
The Discrepancy Pattern
The solicitor's review of the accounts identified several patterns in the unexplained withdrawals that, taken individually, had innocent explanations. Taken together, they formed a pattern inconsistent with routine care expenditure.
| Period | Withdrawal pattern observed | Amount (approx) | Flag |
|---|---|---|---|
| Q1 2024 | Regular cash withdrawals at ATM near Carol's home (not Margaret's) | £3,200 | Location |
| Q2 2024 | Six withdrawals of £500–£800 on days when Margaret was documented as at a hospital appointment | £3,900 | Timing |
| Q3 2024 | Online transfers to an account not in Margaret's name and not previously identified as a regular payee | £4,100 | Destination |
| Q4 2024 | Cash withdrawals increasing significantly in frequency — 14 in 12 weeks vs 3–4 in previous quarters | £5,800 | Frequency |
| Q1 2025 | Continued pattern — further withdrawals at location inconsistent with Margaret's care | £5,000 | Pattern |
| Total unexplained — beyond Carol's partial account | ~£22,000 | Referred for P300 EEG | |
None of these patterns was individually conclusive. ATMs near Carol's home could have been used on the way back from Margaret's care tasks. Hospital appointment days could have involved cash purchases for Margaret. The unrecognised account could have been a legitimate care provider. The increased withdrawal frequency could reflect genuinely increasing care needs. Carol had an explanation for each, individually. The solicitor's view was that the pattern as a whole required a more objective assessment than a meeting with Carol alone could provide.
Investigation Design
The probe design was built through a pre-appointment consultation with Margaret's solicitor, who provided the account analysis, the summary of Carol's explanations, and the specific transaction categories that were most anomalous. Margaret herself was not present for the consultation — the solicitor represented her interests throughout the investigation arrangement.
Carol was invited to participate in the investigation by the solicitor. She was advised to take independent legal advice before consenting, which she did. She ultimately agreed to be tested. The solicitor described her agreement as coming with "reluctance but without refusal."
Probe Set 1 — Purpose of the withdrawals: personal benefit or care expenditure?
Stimuli built around the specific question of whether the unexplained withdrawals had been used for Carol's own benefit rather than Margaret's. The probe tested recognition of specific categories of personal expenditure — Carol's own bills, personal purchases, debt repayment — that would only be neurologically familiar to someone who had used the withdrawn money for those purposes. Also tested: whether Carol held neurological knowledge of a different destination for the funds from the care narrative she had provided.
Probe Set 2 — The unrecognised transfer destination
Stimuli built around the specific account to which the Q3 2024 transfers had been made — an account that Margaret's solicitor had identified as being associated with a third party unknown to the family. The probe tested whether Carol held neurological knowledge of this account's ownership and its connection to her own financial arrangements. This was the most forensically specific probe set in the investigation.
Probe Set 3 — Awareness of the scope of the deception
Stimuli built around the approximate total of the unexplained withdrawals and the period over which they had accumulated — a figure known to the solicitor and the investigation team but not disclosed to Carol during the investigation. Tested whether Carol held neurological knowledge consistent with having tracked the running total as an intentional financial exploitation rather than incidental undocumented spending.
Solicitor briefing and consent arrangement
Carol attended with her own solicitor present for the pre-session briefing. The investigation's scope was explained — that it concerned the unexplained withdrawals from Margaret's accounts during the LPA period. Both solicitors confirmed consent had been obtained. Carol's solicitor did not attend the session itself.
Baseline calibration (10 minutes)
Standard baseline established Carol's individual P300 parameters. Her baseline was well-defined and consistent.
Three probe set sessions (70 minutes)
All three probe sets delivered sequentially. Carol was, by the examiner's assessment, notably tense at the start of the session — more so than most subjects. Surface tension does not affect P300 results.
Result delivered to solicitor — same day
Verbal result delivered to Margaret's solicitor at the close of the session. Written report delivered the following morning. Margaret was informed by her solicitor that afternoon.
Results
Probe Set 2 returned the highest probability score (96%) — the probe set specifically designed around the unrecognised transfer account. Carol's recognition responses to the stimuli relating to this account's ownership and its connection to her own financial arrangements were the most significant finding in the investigation. They were consistent with Carol having directed transfers from Margaret's account to an account she controlled or had a financial relationship with — and specifically inconsistent with Carol having no knowledge of whose account it was.
What the result meant for Margaret
Margaret had described, in her initial conversation with the solicitor, the difficulty of being in this situation — of suspecting a child you love of exploiting the trust you placed in them. She had not wanted to be right. She had hoped the accounts might be explained. The P300 EEG result confirmed what the accounts had suggested: Carol had used the LPA to take money from her mother for her own benefit.
The solicitor described Margaret's response to the result as quiet and clear. She had, he said, already moved through most of the emotional weight of it in the weeks between discovering the discrepancies and receiving the result. She had needed the confirmation not to grieve — she had already grieved — but to act. With the documented result, she could.
Key Investigation Findings
- All three probe sets returned deception-indicated — with the strongest result on Probe Set 2 (transfer destination, 96%), consistent with Carol holding specific knowledge of the ownership and purpose of the account to which Margaret's funds had been transferred.
- Carol's neurological profile was inconsistent with the care expenditure account she had given. A person who had genuinely spent £22,000 of an elderly parent's money on their care would not produce the specific recognition responses recorded on Probe Set 1 — their memory of those transactions would be formed differently.
- Probe Set 3 (scope awareness, 91%) was consistent with Carol having tracked the accumulation of the unexplained withdrawals as an intentional act rather than incidental undocumented spending.
- The investigation was arranged through a solicitor at Margaret's request — providing an additional layer of procedural documentation and ensuring that Margaret's interests as a vulnerable adult were protected throughout.
- The written report was provided to Margaret's solicitor as supporting documentation for the range of legal actions available following a finding of LPA misuse.
Legal and Family Outcomes
LPA revocation — same week as report
Margaret's solicitor filed an application to revoke Carol's LPA for financial affairs. The application cited the account discrepancies and the P300 EEG report as grounds. The revocation was confirmed, and control of Margaret's financial affairs was transferred to a professional deputy appointed by the Court of Protection.
Office of the Public Guardian referral
The matter was referred to the OPG for investigation under their serious concerns process. The P300 EEG report was included in the referral documentation alongside the financial analysis. OPG investigation was initiated.
Civil recovery proceedings
The solicitor issued a letter before action to Carol on behalf of the estate for recovery of the unexplained withdrawals. Carol did not respond within the required period. A civil claim was filed for £22,000 plus costs. Carol indicated through her solicitor that she wished to reach a settlement.
Partial settlement agreed — estate protected
A settlement was reached for partial recovery, with the balance to be recovered from Carol's share of any future inheritance. The settlement terms were structured by the solicitor to ensure Margaret's estate was protected regardless of the outcome of the OPG investigation.
Estate planning review completed
With the LPA revoked and the professional deputy in place, Margaret's solicitor completed the estate planning review that had originally identified the discrepancies. Margaret's will was reviewed and updated to reflect the circumstances. The P300 EEG report was retained as part of the permanent estate file.
What This Case Demonstrates
LPA misuse is one of the hardest elder financial abuse cases to prove without neurological evidence
An attorney acting under an LPA has legal authority to make the transactions they make. Every withdrawal Carol made from Margaret's accounts was technically authorised by the LPA. The question was never whether the transactions had occurred — they were all documented — but whether they had been made for Margaret's benefit as the LPA requires. That question is specifically about Carol's intent and knowledge, not about the transactions themselves. P300 EEG addresses intent and knowledge directly. Financial records cannot.
Arranging through a solicitor provides additional procedural protection
In cases involving elderly or vulnerable clients, arranging P300 EEG through a solicitor provides several important safeguards: the client's interests are represented throughout; the investigation is conducted within the context of appropriate legal advice; the subject also has access to independent legal advice before consenting; and the result is delivered into a legal context in which it can be acted upon immediately. Margaret's solicitor described the process as "exactly the kind of independent evidence that this type of case needs — and rarely gets."
The result enables action where ambiguity had prevented it
Before the P300 EEG investigation, the family had the account discrepancies and Carol's partial explanation. They could not revoke the LPA, pursue civil recovery, or refer to the OPG on the basis of unexplained withdrawals and a suspect pattern alone — not without exposing themselves to a counter-claim from Carol that the action was unwarranted. The P300 EEG report provided the documented evidential basis for every legal step taken after it. Without it, the family's options were substantially more limited and substantially more risky to exercise.
