What a Letter of Competency Is
A letter of competency is a clinician’s written assessment of someone’s mental functioning, or of their ability to make a particular decision.
Families ask for one when an older parent wants to sign estate planning documents — usually after a diagnosis, or when somebody expects an argument. The letter can be useful evidence. It does not automatically make every document that person signs valid. What it is worth depends on what was assessed, when, and how closely that relates to the decision in front of you.
Massachusetts Does Not Require One to Sign a Will
There is no rule that an older Massachusetts resident needs a doctor’s letter before signing a will. Massachusetts law lets an adult of sound mind make a will, and the question is the capacity required for that act.
Age does not answer it. Someone in their nineties may understand their estate plan completely, while a much younger person may be unable to understand a transaction because of illness. Massachusetts General Laws c.190B § 2-501, who may make a will.
Capacity Is Tied to the Specific Decision
For a will, Massachusetts cases look at things like the person’s general understanding of what they own, the people who would naturally have a claim on their consideration, and the nature of making a will. Other transactions carry different standards.
So a general statement that somebody is “competent” is often less useful than an assessment aimed at the understanding the particular document requires. Massachusetts Supreme Judicial Court explanation of testamentary capacity.
A Dementia Diagnosis Does Not Settle It Either Way
A diagnosis does not automatically mean estate planning is impossible. And in the other direction, someone recognizing relatives, holding a pleasant conversation and signing their name does not establish the understanding a particular transaction requires.
The attorney has to make that assessment. Medical information helps by explaining what the limitations actually are. Where it makes sense, the legal and clinical evaluations should be coordinated so the clinician knows which abilities are the relevant ones.
Why Timing Matters
The question is nearly always about capacity at the moment the document was signed. A letter written well before a significant decline tells us very little about a signing that happened afterwards.
An evaluation carried out close to the relevant date is far more useful, particularly when it records the observations and the reasoning behind the opinion. Temporary illness, medication, fatigue and fluctuating cognition may all need to be taken into account before deciding whether to go ahead, and when.
The Clinician’s Job and the Attorney’s Job Are Different
A medical professional assesses functioning and reports what they found. The attorney has to weigh the legal standard, the client’s instructions and the signing process itself.
If it ever reaches a courtroom, the judge weighs the evidence. A letter does not replace that analysis, and notarizing something does not settle it either. What you want is a sound decision-making and signing process, supported by appropriate evidence.
Capacity Is Not the Same as Undue Influence
Someone can understand exactly what they are signing and still be under improper pressure.
That is why the attorney may need to meet privately with the client, ask why the changes are being made now, and take note of who arranged the appointment and who supplied the instructions. A medical opinion about cognition says nothing about whether a beneficiary leaned on somebody to make a particular gift.
When Capacity Is Already Gone
If the person cannot validly execute what is needed, no letter restores what is missing.
Existing powers of attorney, trusts and health care documents should be reviewed first, and conservatorship or guardianship may be necessary depending on the decisions that have to be made. Those proceedings carry their own medical documentation requirements. Massachusetts guidance on guardianship and conservatorship documentation.
