Abstract
This guide explains lPA capacity assessments for solicitors and families for Mental Capacity Assessment to Grant Lasting Power of Attorney in England and Wales. It gives a decision-specific overview of relevant information, evidence, risk factors, report quality and when a formal assessment may be needed.
LPA capacity assessments for solicitors and families
LPA capacity assessments serve solicitors and families slightly differently. For solicitors, the assessment provides certificate-quality evidence that the donor met the test at execution, protects the file where a diagnosis or family friction raises risk, and supports the certificate provider role where an independent professional is preferred. For families, it settles worry: it either confirms the person can still put an LPA in place, often the most valuable planning step after a diagnosis, or identifies that the moment has passed and deputyship is the honest route. Either answer, evidenced early, prevents far more expensive problems later. This guide explains the process for both audiences.
Two audiences, one instrument
LPA capacity assessments are commissioned by two overlapping audiences with different anxieties. Solicitors need confidence that the retainer is sound and the instrument will survive scrutiny; families need a trusted answer to whether a parent or partner can still put their affairs in order, often against a diagnosis that has just arrived. The assessment itself is the same disciplined exercise for both, and this guide addresses what each audience needs from it and from each other.
What solicitors need the assessment to do
For the drafting solicitor, the assessment answers the professional question of whether the client can give instructions for and execute the instrument, and it converts the file from assertion into evidence: a contemporaneous, independent, decision-specific report alongside the attendance notes. Where the donor's presentation raised the doubt, the report resolves it in either direction, and where the instrument may be attacked, family exclusion, late changes, a new relationship benefiting, it is the exhibit the defence will lean upon.
What families need the assessment to do
For families, the assessment answers a practical and emotional question: can this still be done, and is it truly what our relative wants. A good assessment gives the donor a private, supported opportunity to show their understanding and express their wishes away from everyone's expectations, and it protects the family too, because the sibling who arranged the LPA is the first accused if it is later questioned, and independent evidence is the answer to that accusation before it is made.
When to commission a formal assessment
Not every LPA needs one. The formal assessment earns its cost where a diagnosis affecting cognition exists, where presentation is borderline or fluctuating, where the family is divided or an attack on the instrument is foreseeable, where the estate is substantial or where the arrangement departs from expectation. In those cases the certificate provider's confirmation, though still required, is not evidence built for examination, and the assessment supplies what it cannot.
How instruction usually works
Either audience can instruct directly. Solicitors typically define the instrument, enclose the draft and the relevant background and coordinate timing with execution; families typically describe the situation, the diagnosis and the worry, and the assessor shapes the formal instruction from there. In both routes the essentials are the same: the decision named, the context disclosed including any family tension, the records enclosed and the donor's communication needs and best times identified before the visit.
The visit, from the donor's side
For the donor, the assessment is a conversation, usually at home, usually within an hour or two, with the assessor alone for its substance. The instrument is explained in plain language, piece by piece, and the donor is asked to explain it back: what it is, what the attorneys could do, when, and what they think of that. Nobody is tricked or tested on trivia, support is given throughout and the aim, stated openly, is to let the donor demonstrate whatever understanding they genuinely have.
Timing the assessment with execution
The evidence is strongest when assessment and execution sit close together, ideally within days, so the report speaks to the donor's capacity at the time the instrument was actually made. Solicitors should coordinate the certificate, the assessment and signature within the same window, and where the condition is progressive, treat the window as closing: an assessment finding capacity is an instruction to complete promptly, not a comfort that allows the file to wait.
After the report: the three outcomes
The report lands in one of three places. Capacity present: execute promptly, file the report and the instrument stands protected. Capacity absent: the LPA cannot proceed, and the same evidence founds a deputyship application, so nothing is wasted. Borderline or not yet: the report says what support, timing or treatment might change the position and when to reassess. Each outcome serves the donor, because each replaces uncertainty with a documented position everyone can act upon.
Key takeaway
LPA capacity assessments serve solicitors and families with the same instrument of evidence: a private, supported, decision-specific assessment of the donor, timed to execution and written for later scrutiny. Commission it where doubt or dispute threatens, coordinate it with signature and act on whichever of the three outcomes it delivers, because every one of them leaves the donor better protected than the uncertainty it replaced.
Frequently asked questions
Does a diagnosis automatically mean someone lacks capacity?
No. A diagnosis may explain why capacity is in doubt, but it does not answer the legal question. The assessment must still consider the specific decision, the relevant information, the support provided and whether the person can understand, retain, use or weigh that information and communicate a decision.
What evidence is useful for Mental Capacity Assessment to Grant Lasting Power of Attorney?
Useful evidence will depend on the facts, but it commonly includes draft or registered LPA documents, OPG correspondence, solicitor notes, family background, medical records and information about any concerns regarding pressure, coercion or fluctuating capacity. The assessor should record which documents were reviewed and separate direct observations from information supplied by others.
When is a formal assessment for Mental Capacity Assessment to Grant Lasting Power of Attorney useful?
Assess promptly after any concerning diagnosis. The window in which a person can validly grant an LPA is precious: used in time it avoids deputyship entirely, and the assessment evidences the LPA against any later objection.
