As a general rule, it is a person’s age that determines whether they possess legal capacity. Persons below the age of 13 lack it entirely; between 13 and 18 it is limited; and upon reaching adulthood it becomes full. There is, however, one very significant exception to this rule — incapacitation (ubezwłasnowolnienie).
Full and Partial Incapacitation
The matter of incapacitation is governed by the Civil Code. Pursuant to Article 13, a person who has reached the age of 13 may be fully incapacitated where certain circumstances — mental illness, intellectual disability, or other disorders such as addiction — mean that they are unable to conduct their own affairs.
The wording of this provision may not be entirely felicitous; however, it is clear from its terms that full incapacitation applies only to extreme situations in which the capacity to direct one’s own conduct is wholly extinguished.
Article 16, for its part, concerns partial incapacitation. Analogous circumstances are taken into account, but they must produce less severe consequences — the person need not be fully incapacitated, yet requires assistance in managing their affairs.
Consequences of Incapacitation
As I indicated in the introduction, a person’s legal capacity may exist at one of three levels — absent, limited, or full. Full incapacitation results in the person being wholly deprived of legal capacity. Partial incapacitation results in that capacity being limited. In practice, this means that a fully incapacitated person is treated in the same way as a child below the age of 13, whilst a partially incapacitated person is treated as a child between the ages of 13 and 18.
Critically, such a person is not left without support. A guardian (opiekun) — whose role is analogous to that of a parent exercising parental authority — is appointed for a fully incapacitated person, whilst a curator (kurator) — who supervises the person’s legal acts — is appointed for a partially incapacitated person.
Procedure
Given the profound significance of incapacitation, the decision to apply it rests with the Court, which acts pursuant to a special procedure. That procedure requires, amongst other things, the production of medical documentation confirming the existence of circumstances that would justify incapacitation, as well as expert opinions. In the course of the proceedings, the person who is to be incapacitated should be heard and afforded appropriate representation. All of these safeguards exist to prevent the institution of incapacitation from being misused in bad faith to deprive a person of the ability to function independently.
Also of critical importance is the fact that incapacitation is reversible — should the circumstances justifying it cease to exist, the Court may order that it be lifted.
