Focus Families seeking legal protection for a person with disabilities.
Main risk Requesting a measure that is too broad, insufficient or disconnected from the person’s real assets and needs.
Useful decision Choose the proportionate support before starting or reviewing a file.
These are the 7 keys to support measures under Law 8/2021 that families should review:
- 01 Legal capacity is no longer automatically substituted
- 02 Voluntary support is the first level of protection
- 03 De facto guardianship may be enough if it works properly
- 04 Curatorship is reserved for ongoing support
- 05 A judicial defender covers temporary situations or conflicts
- 06 Important asset decisions require special control
- 07 Measures should be reviewed when circumstances change
The support measures under Law 8/2021 exist so that a person with disabilities can exercise legal capacity with the assistance they need. The reform abandoned the traditional language of incapacitation and placed the focus on support, proportionality and respect for the person’s will, wishes and preferences.
For a family, the important question is not usually how to incapacitate someone, but what support the person needs, who can provide it safely, which acts require judicial authorisation and how to protect assets without cancelling autonomy.
This is decisive in situations involving intellectual disability, cognitive decline, mental illness, dependence, vulnerable assets or family conflict. The same diagnosis can lead to different legal measures depending on autonomy, communication, assets, family support and the decisions at stake.
This guide explains voluntary support, de facto guardianship, curatorship, judicial defender and review of measures, with a practical focus on risks, documents and decision criteria.
7 keys to choosing support measures without leaving the person unprotected
1. Legal capacity is no longer automatically substituted
Law 8/2021 changed the starting point. A person with disabilities keeps legal capacity and support measures should help them exercise it on equal terms. The amended Civil Code requires measures to respect dignity, fundamental rights and the person’s will, wishes and preferences.
This has a practical consequence: a broad measure should not be requested if a specific support is enough. The analysis should focus on need, proportionality and concrete legal acts, not only on a medical diagnosis.
- Which decisions the person can make with reasonable support.
- Which acts require stable, occasional or representative assistance.
- Which real risks exist if no measure is adopted.
2. Voluntary support is the first level of protection
Voluntary support measures are those established by the person themselves, normally in a public deed, to appoint who they want to assist them and with what scope. They may include preventive powers of attorney, mandates, self-curatorship instructions, rules of action, safeguards and criteria for managing certain decisions.
Article 250 of the Spanish Civil Code places these measures within the support system, together with de facto guardianship, curatorship and judicial defender. In practice, they are especially useful when the person can still express their will clearly and wants to anticipate future scenarios.
3. De facto guardianship may be enough if it works properly
De facto guardianship exists when someone provides real support without necessarily having been appointed by a court. Law 8/2021 gave it greater recognition because many families already worked this way: a child supports an elderly parent, a sibling helps with bank procedures or a parent supports an adult child with disabilities.
The Spanish Civil Code allows a person who has been properly exercising de facto guardianship to continue doing so, even where voluntary or judicial measures exist but are not being applied effectively.
However, de facto guardianship is not suitable for every act. Where a representative act is required, the guardian may need judicial authorisation. Selling real estate, accepting an inheritance, waiving rights or entering into a transaction can require a different level of control.
4. Curatorship is reserved for ongoing support
Curatorship is the stable judicial measure for people who need continuous support. It should not be requested automatically or as a general substitution of the person’s will. The court must justify why no other sufficient support measure exists.
Curatorship may involve assistance and, only exceptionally, representative functions. This means the curator usually helps, informs and accompanies decisions, but does not decide for the person unless the court authorises representation for specific acts.
- Which areas need support: assets, health, housing, contracts, benefits, inheritance or procedures.
- Which acts the person can carry out alone.
- Which acts require curator assistance or exceptional representation.
- Which safeguards prevent abuse or family conflict.
5. A judicial defender covers temporary situations or conflicts
A judicial defender is not designed to replace stable curatorship. It is usually temporary, specific and linked to a conflict of interest, absence or impossibility of the person providing support, an urgent need or the handling of a particular file.
It can be useful, for example, where the person with disabilities must participate in an inheritance in which the family member who supports them also has personal interests. It may also be appointed where assets need protection while the main procedure is pending.
6. Important asset decisions require special control
Support measures often become more sensitive when they affect housing, inheritance, bank accounts, investments, protected assets, pensions or tax obligations. The aim is not to block the person’s financial life, but to avoid acts that are abusive, harmful or vulnerable to challenge.
Before signing an important asset transaction, it is advisable to check whether the person understands the act with suitable support, whether a voluntary measure, de facto guardianship, curatorship or judicial defender exists, whether judicial authorisation is required and whether there are conflicts of interest.
7. Measures should be reviewed when circumstances change
Judicial support measures are not immutable. They should remain proportionate to the person’s needs and must be reviewed periodically or when the situation changes. This is especially relevant for families with old judgments, broad measures or circumstances that no longer match reality.
A review may be appropriate if the person has gained autonomy, needs new support, the curator can no longer act properly, family conflict has appeared, assets have changed or an inheritance, sale, residential care decision or change of home is approaching.
Which support measure may fit each family situation
There is no single answer for every family. The same disability may require different support depending on autonomy, communication, assets, family network, conflict and existing documents.
| Situation | Measure that may fit | Risk if chosen poorly |
|---|---|---|
| The person can decide and wants to anticipate the future | Voluntary support, preventive powers or self-curatorship | Losing the chance to leave clear instructions |
| A relative provides daily support and there is no conflict | De facto guardianship | Unnecessary judicialisation or acting without authorisation in relevant acts |
| Stable support is needed in several areas | Assisting curatorship | Requesting a measure that is too broad or unclear |
| A specific act involves a conflict of interest | Judicial defender | The act may be challenged or harmful |
| There are assets, inheritances or real estate | Support measure plus authorisations if required | Disposing of assets without sufficient control |
Proportionate protection
Is curatorship needed or is a lighter support enough?
Before going to court, distinguish daily support, judicial authorisation, conflict of interest and need for ongoing support.
Documents to gather before requesting support measures
To prepare a legal consultation about support measures, it is useful to gather personal, medical, asset and family documentation. Not all documents will always be needed, but they help identify the most proportionate path.
- ID documents for the person and relevant relatives.
- Disability certificate, if available.
- Updated medical, social or psychological reports.
- Previous court decisions, if any.
- Public deeds for powers, mandates, self-curatorship or advance instructions.
- Housing, real estate or lease documents.
- Bank certificates or relevant asset information.
- Benefits, pensions or public aid documents.
- Wills, pending inheritances or relevant gifts.
The voluntary jurisdiction procedure may require documents evidencing the need for support and expert reports from social and health professionals. The Spanish Voluntary Jurisdiction Act is therefore a relevant official source when preparing the file.
Common mistakes when requesting support measures
Requesting curatorship without considering lighter supports
Curatorship may be necessary, but it should not be the automatic first answer. If voluntary supports or de facto guardianship work, it may be enough to request authorisation for a concrete act.
Confusing support with total substitution
The reform requires respect for the person’s will, wishes and preferences. A measure designed to remove the person entirely from decisions may clash with the current legal framework.
Not anticipating conflicts of interest
In inheritances, sales or asset management, the person who supports the individual may also have their own interests. In those cases, a judicial defender or specific safeguard may be needed.
Ignoring tax and administrative effects
A support measure may affect accounts, real estate, benefits, taxes, protected assets or inheritances. Separating civil law from tax and administration often leads to incomplete decisions.
Not reviewing old measures
Some families keep old decisions without checking whether they still fit. A review can adjust functions, change supports, reduce excesses or solve gaps.

Frequently Asked Questions (FAQs)
What are the support measures under Law 8/2021?
They are legal mechanisms that help a person with disabilities exercise legal capacity with the assistance they need. They may be voluntary, informal or judicial, including preventive powers, de facto guardianship, curatorship and judicial defender.
Does judicial incapacitation still exist in Spain?
The traditional model was replaced by a support system. The current approach is not to modify the person’s capacity, but to determine which support they need to exercise it.
When is curatorship appropriate?
Curatorship may be appropriate when the person needs ongoing support in one or several areas and lighter measures are not sufficient. It should be tailored to concrete acts and should not be requested automatically.
Can de facto guardianship be enough?
Yes, where it works properly and there is no need for broader judicial support. However, certain representative acts or important asset decisions may still require judicial authorisation.
When should support measures be reviewed?
They should be reviewed when the person’s circumstances change, when existing support no longer works, when family conflict appears, or when the measure is too broad or too limited for the current situation.
Why coordinate civil support with asset and tax advice?
Because support measures may affect inheritances, real estate, bank accounts, benefits, taxes and family administration. Coordinating these areas helps protect the person’s autonomy and the security of their assets.
