Who Performs a Capacity Evaluation, and When

There is no single professional who performs a capacity evaluation, because capacity is not one thing: it is decision-specific, and the person qualified to assess whether your mother can sign a power of attorney is not necessarily the person qualified to say whether she can manage a $200,000 financial transaction. Families ask for a general opinion, receive a general opinion, and discover months later that it answered nothing.

If you are here, something has probably already gone sideways. A parent signed something the family did not know about, or a bank refused a transaction, or one sibling says Dad is fine and another says he is not, or a lawyer has asked for a physician’s letter and nobody knows what kind. It is a raw situation, and it is made worse by the fact that the words involved are used loosely by everyone including professionals.

What follows are the six ways this goes wrong, roughly in order of how often they happen, and the specific step that prevents each one. Pine Lake Legacy provides education and a free policy review only; nothing here is legal or medical advice, and a genuine capacity dispute belongs with an elder law attorney and a qualified clinician, not with a website.

Who Performs a Capacity Evaluation, and When

Treating a Screening Score as a Verdict

This is the most common error by a wide margin. Someone scores 21 out of 30 on the Montreal Cognitive Assessment, and the family concludes that Dad cannot sign anything. That is not what the instrument does. The MoCA, the Mini-Mental State Examination, the Mini-Cog and the Saint Louis University Mental Status examination are screening tools designed to flag possible impairment and prompt further evaluation. They are not legal determinations and they do not measure a specific decision.

The MoCA in particular is often administered badly. It requires the administrator to be trained and certified, and scoring adjustments apply for limited education. A rushed administration in a busy office produces a number that will not survive scrutiny if anyone ever challenges it.

What prevents it: ask the physician for the assessment that actually exists as a service rather than a hallway score. Medicare covers detection of cognitive impairment as part of the annual wellness visit, and separately covers a dedicated cognitive assessment and care planning visit that includes a standardised assessment, a medication review, a functional assessment and a written care plan. Ask the practice to schedule that visit specifically and to put the findings in the chart, because a documented assessment is worth more than a score written on a sticky note.

Asking for a Global Opinion When the Decision Needs a Specific One

Second most common, and the one that wastes the most money. Capacity is task-specific and the legal standards differ by task. Testamentary capacity, the standard for signing a will, is famously low: broadly, that the person understands they are making a will, has a general sense of what they own and who their natural heirs are, and understands how those relate. Contractual capacity, the standard for entering a binding financial agreement, generally asks whether the person understands the nature and consequences of that specific transaction. The capacity to execute a durable power of attorney, to consent to medical treatment, or to change a beneficiary designation each have their own framing.

A letter saying the patient has mild cognitive impairment answers none of those. A letter saying the patient can identify her assets, name her children, describe what a life insurance policy is and explain what would happen if she sold one, answers a real question.

What prevents it: have the attorney write the question. The joint publications of the American Bar Association Commission on Law and Aging and the American Psychological Association, including their handbooks for lawyers, psychologists and judges on assessing older adults with diminished capacity, exist precisely to bridge this gap and are worth putting in front of a clinician who has not done this before. Our page on capacity questions in policy decisions covers the version of this question that comes up with insurance.

Evaluating Before Reversible Causes Have Been Ruled Out

An older adult who is acutely confused in a hospital bed is frequently delirious rather than demented, and delirium is treatable. Urinary tract infection, dehydration, pain, hypoxia, constipation, alcohol withdrawal and medication effects, particularly anticholinergic and sedative burden, all produce confusion that fluctuates through the day and clears when the cause is treated. Dementia does not clear.

Evaluations run during an acute illness routinely understate a person’s baseline, and a family that acts on one can strip decision-making authority from someone who would have recovered it in a fortnight. The reverse error also happens: a well-rehearsed person can present convincingly for twenty minutes in a quiet room while being unable to function at home.

What prevents it: ask two questions before scheduling anything. Has delirium been ruled out and reversible causes treated, and can this be done at the person’s best time of day in a familiar setting rather than late afternoon in an unfamiliar clinic. Ask for a full medication review, which is a service a pharmacist can perform. And if the evaluation must happen during a hospitalisation, ask that it be repeated after discharge and recovery. Our overview of who decides on a dementia diagnosis sets out the clinical chain.

Who	What They Can Actually Say	Typical Cost (2026)	When to Use Them
Treating physician	Clinical impression, medication review, a letter tied to a specific decision	Covered visit; ask about the cognitive assessment and care planning service	First stop for almost every situation
Neuropsychologist	Detailed profile across memory, executive function and judgment	Roughly $2,000 to $6,000 privately; Part B covers when medically necessary	When the answer is close or contested
Geriatrician or geriatric psychiatrist	Distinguishes delirium, depression and dementia	Covered visit; waiting lists are common	When confusion is new or fluctuating
Occupational therapist	Functional performance on real tasks, including money management	Covered when ordered as medically necessary	When the question is daily functioning
Court-appointed evaluator or guardian ad litem	An opinion for the court in a guardianship proceeding	Guardianship commonly runs several thousand dollars and up	Only when less restrictive options have failed
Forensic evaluator	An opinion prepared for litigation	Typically higher and usually not insurance-covered	Active or expected litigation

Evaluating Before Reversible Causes Have Been Ruled Out

Letting the Interested Party Choose the Evaluator

The adult child who stands to inherit arranges the appointment, drives the parent there, sits in the room and answers on their behalf. Even where everyone means well, the resulting opinion is worth very little if it is ever contested, and if it is contested the arrangement itself becomes the story.

The same problem appears in the other direction, where a family member seeking control commissions an opinion from a clinician who has never met the person before and spends thirty minutes with them.

What prevents it: separate the roles deliberately. The person being evaluated should be interviewed alone for at least part of the session. The referral should come from the treating physician or from an attorney representing the older adult, not from a beneficiary. Where a real dispute exists, expect the court to appoint its own evaluator, a court visitor, or a guardian ad litem, and expect the alleged incapacitated person to have their own attorney. Know the costs: a full neuropsychological evaluation involves several hours of standardised testing and commonly runs $2,000 to $6,000 as of 2026 privately, with Medicare Part B covering neuropsychological testing when medically necessary subject to the deductible and coinsurance; a forensic evaluation prepared for litigation is usually more and is usually not covered at all. Confirm coverage with the plan before booking. Where siblings are already at odds, read what a family fight over capacity actually looks like before anyone books an appointment.

Mistaking Hearing Loss, Vision Loss or Language for Confusion

An 84-year-old who cannot hear the questions scores badly on tests that are read aloud. Someone whose first language is not English, tested in English by an examiner using an interpreter who has no training in cognitive testing, scores badly for reasons that have nothing to do with cognition. Low formal education depresses scores on several instruments unless the scoring adjustment is applied. Severe vision loss makes clock-drawing and copying tasks meaningless.

These are not edge cases. They are among the most common reasons a capacity opinion is later withdrawn or disregarded, and they fall hardest on exactly the people least able to push back.

What prevents it: state the sensory and language facts in writing when you make the referral, and ask for accommodations by name. Hearing aids in and working, or a personal amplifier. Adequate lighting and reading glasses. Testing in the person’s primary language by an examiner who speaks it, or with a trained interpreter and instruments validated in that language. And ask the examiner to note in the report what accommodations were used, because a report that is silent on the subject invites a challenge.

Doing It Afterwards Instead of at the Signing

The most expensive mistake of all. A document gets signed, questions arise a year later, and someone asks a clinician to opine retrospectively on capacity on a date they were not present for. Retrospective opinions are weak, they are expensive, and they turn into duelling experts.

The fix costs almost nothing and belongs to the moment of signing. Have the attorney supervising the execution make a contemporaneous note of what the signer said in their own words about what the document does. Consider a physician’s letter dated within days of the signing, addressed to the specific decision. Use disinterested witnesses. Keep the drafts and the correspondence showing the signer’s instructions developed over time rather than appearing in one visit.

The related failure is the springing power of attorney that never springs. Documents drafted to take effect only on a physician’s certification of incapacity routinely stall because no physician is willing to sign, or because the certification standard in the document does not match anything a doctor recognises. Ask the drafting attorney whether an immediately effective durable power is more appropriate, and note that in states following the Uniform Power of Attorney Act, certain acts, including changing beneficiary designations and making gifts, require an express grant of authority in the document itself rather than general language. Our explainers on durable powers of attorney and health care proxies cover the difference between the two instruments.

Where the Life Insurance Policy Sits While All This Is Unresolved

Be plain about this. If capacity to make a specific financial decision is genuinely in question, the policy should not move. A transaction signed by someone whose capacity is contested invites rescission, family litigation and a regulatory complaint, and no legitimate buyer wants that file. Reputable providers ask for a physician’s attestation or an attorney’s certification when there is any question, and a party that does not ask is a party to walk away from; our list of red flags worth walking away from covers the rest.

Meanwhile, the policy still needs to stay alive. Premiums must be paid, and a lapse during a capacity dispute destroys value for every side of the argument. Ask the carrier to add a designated third party to receive lapse notices, a service most carriers offer at no cost and one that exists for exactly this situation. That one form is the highest-value action in this whole article.

Also be clear about when selling would be wrong even if capacity were not in question. A small burial or final expense policy of $10,000 or $25,000 is below the size the secondary market considers and is doing the job it was bought for. A healthy insured draws weak offers because projected life expectancy is long. A term policy with no conversion right generally has no market value. And a policy a surviving spouse still needs for income or estate liquidity should stay in force. Our page on when a life settlement is a bad idea sets out the full list.

If financial exploitation is part of the picture, route it rather than investigate it. Adult Protective Services in your state takes reports of suspected elder financial abuse. The state insurance department handles complaints about agents and insurers, the state securities regulator handles investment products, and local law enforcement handles theft. Pine Lake Legacy does not investigate or intervene in these matters, does not purchase policies, and does not give legal or medical advice. If a policy is simply sitting there and you want to know what it is, send the cover page for a free review or call (732) 978-9575 — but if capacity is contested, resolve that first.

Frequently Asked Questions

Is a low MoCA or MMSE score enough to say someone lacks capacity?

No. Those are screening instruments meant to flag possible impairment and prompt further evaluation, not legal determinations, and they are frequently administered without the required training or the education-based scoring adjustment. Ask instead for a documented cognitive assessment tied to the specific decision at hand, and ask that it go into the medical record.

Who should perform the evaluation?

It depends on the decision. The treating physician is the first stop for most situations. A neuropsychologist gives the most detailed picture when the answer is close or contested. A geriatrician or geriatric psychiatrist is best when confusion is new or fluctuating. In a guardianship proceeding, the court appoints its own evaluator regardless of what the family arranged.

What does a capacity evaluation cost?

A physician visit is generally covered. A full neuropsychological evaluation commonly runs $2,000 to $6,000 privately as of 2026, with Medicare Part B covering neuropsychological testing when medically necessary, subject to the deductible and coinsurance. A forensic evaluation prepared for litigation typically costs more and is usually not covered. Confirm coverage before booking.

Can a family member sit in on the evaluation?

Part of the session should be conducted with the person alone, and the referral ideally comes from the treating physician or from an attorney representing the older adult rather than from someone who stands to benefit. An evaluation arranged and attended throughout by an interested party carries very little weight if it is ever challenged.

Is capacity the same as competency?

No. Capacity is a clinical judgment about a specific decision at a specific time, and it can fluctuate. Competency, in most usage, is a court’s legal determination, typically made in a guardianship or conservatorship proceeding. People commonly have capacity for some decisions and not others, which is why a global opinion is rarely the useful answer.

Can someone with dementia still sign a power of attorney?

Sometimes, because the standard is decision-specific and early-stage dementia does not automatically remove capacity for every act. That is a question for the attorney supervising the execution together with a clinician, documented at the time of signing rather than reconstructed later. Note that some states require an express grant for acts such as changing beneficiary designations.

What should happen to a life insurance policy while capacity is disputed?

It should not be sold, transferred or surrendered until the question is resolved, because a contested signature invites rescission and litigation. Keep it in force: ask the carrier to add a designated third party to receive lapse notices, which most carriers do at no charge, so a missed premium does not destroy the asset everyone is arguing about.
