When Alzheimer's or another serious illness erodes a person's ability to make decisions, families can face emotional turmoil alongside legal and financial obstacles. Notary María Cristina Clemente Buendía, based in Alicante, is urging people to consider a solution that remains unfamiliar to many: the preventive power of attorney.
As Clemente explains in a recent social media video, this notarial document allows an individual to designate someone they trust to act on their behalf if they later need support managing their affairs. Unlike a will, which concerns what happens after death, a preventive power of attorney is intended to operate during the grantor's lifetime. Under Spanish law, it can be arranged to remain effective if support needs arise or to take effect only when specified circumstances occur.
How the Preventive Power of Attorney Works
Information from the Consejo General del Notariado, a preventive power of attorney is formalized as a public notarial document. It allows the grantor to appoint one or more people to represent or assist them in the future if they need support. Its scope can include property, banking and contractual dealings, as well as personal management, subject to the powers set out in the document and the limits of Spanish law.
The structure was reshaped by Law 8/2021, of 2 June, which reformed civil and procedural legislation on support for people with disabilities in exercising their legal capacity. The reform moved away from broad substitute decision-making and toward support measures that respect the person’s will, wishes and preferences. A preventive power of attorney can help families avoid seeking court authorization for matters already covered by the mandate, but it does not rule out every possible court proceeding.
Clemente points to a common scenario: a person with Alzheimer's needs to move into a care home, but their assets are tied up in property rather than cash. Selling the family home may require a legally effective act by the owner or an authorized representative. If no suitable mandate is in place, relatives may need to seek judicial support to manage the person's affairs, potentially causing delays and family tensions. Disputes, conflicts of interest, allegations of abuse or matters beyond the document's scope may also require judicial intervention.
Timing Is Critical
Clemente stresses that the basic is to arrange the document while the person can understand the decision, express their wishes and establish the mandate before a notary. Spanish civil law allows powers to be drafted so they continue if future support is needed, or take effect only under specified circumstances. The notarial instrument records the grantor's consent and defines the authority given to the representative.
Even in the early stages of a diagnosis, it may still be possible to grant this power if the individual can make and communicate the relevant decision. Alzheimer's is a progressive neurodegenerative disease associated with declining memory, thinking and behavior. Its effects can make it increasingly difficult to understand transactions or communicate decisions. Early planning gives the person an chance to choose who may assist or represent them, in keeping with their preferences.
What the Appointed Person Can Do
The authority granted by a preventive power of attorney is not unlimited. The document should specify the powers granted, the areas in which the representative can act and the conditions for using those powers. It can also establish whether one person acts alone, several act jointly or representatives act in succession.
Spanish law’s support model emphasizes proportionality and respect for the individual’s preferences. The mandate can include instructions and oversight arrangements, along with safeguards against possible abuse or conflicts of interest. It is a planning tool, not blanket authorization to disregard protections governing the person’s assets. Court involvement may still be needed when voluntary arrangements are insufficient or a matter falls outside the mandate.
With the appropriate powers, the appointed person may be able to sell property, manage bank accounts, pay for care or handle other financial matters on the grantor’s behalf. The mandate operates during life and is distinct from succession planning: it cannot replace a will or determine inheritance. Its terms and the applicable legal safeguards govern how it may be used.
Why Early Action Matters
Many families learn about the preventive power of attorney only when it is too late to establish one. By planning early, individuals can specify who may assist or represent them and set out the scope and conditions of that support. The measure can complement medical assessment and social-care planning, but it does not replace either. Spain’s Instituto de Mayores y Servicios Sociales maintains the Centro de Referencia Estatal de Atención a Personas con Enfermedad de Alzheimer y Otras Demencias, a public resource focused on dementia-related knowledge, care and support. As Spain’s population ages and dementia remains a impressive care challenge, advance legal planning can help families prepare while keeping the person’s wishes at the center.
