How to Apply for Adult Protection in Switzerland: KESB Deputyship / Guardianship Step‑by‑step

Understanding how to apply for adult protection in Switzerland is essential for any relative, carer, clinician or fiduciary who believes an adult can no longer manage their own personal or financial affairs. The process centres on the KESB (Kindes‑ und Erwachsenenschutzbehörde), the cantonal child and adult protection authority that investigates concerns, assesses capacity and, where justified, appoints a deputy (Beistand) with defined powers under the Swiss Civil Code (ZGB Art. 360 ff. ). This guide sets out the full adult protection procedure: eligibility criteria, the step-by-step KESB deputyship application, required documents, realistic timelines, costs, and the important cross‑border recognition changes that took effect on 1 January 2026.

Whether you are initiating a request or responding to a KESB notice, the information below will help you prepare effectively and avoid the most common procedural mistakes.

Overview of the Adult Protection Process and Who It Applies To

Swiss adult protection law is governed by ZGB Art. 360 ff. and administered at cantonal level by the KESB. The system is designed to intervene only as far as necessary, a core principle known as proportionality, and it offers several types of protection measures rather than a single, one‑size‑fits‑all guardianship.

What is the KESB?

The KESB is an interdisciplinary authority composed of legal, social-work and psychological or medical professionals. Each canton has one or more KESB offices. Their role is to receive reports and applications concerning adults who may lack decision-making capacity, to investigate those concerns, and, if warranted, to order a specific protection measure and appoint a suitable deputy.

Types of protection measures

The ZGB provides a graduated range of measures, from least to most invasive:

• Begleitbeistandschaft (accompanying deputyship). Advisory and supportive, the deputy assists but cannot act without the person’s consent.
• Vertretungsbeistandschaft (representative deputyship). The deputy may act on the person’s behalf in defined areas (e.g., finances, medical decisions, housing).
• Mitwirkungsbeistandschaft (cooperative deputyship). Certain transactions require the deputy’s co-signature to be valid.
• Umfassende Beistandschaft (comprehensive deputyship). Equivalent to full guardianship, ordered only when no lesser measure suffices.
• Fürsorgerische Unterbringung (involuntary placement). A separate, urgent measure allowing placement in a suitable institution for treatment or care.

When to consider applying

• An adult has lost, or is progressively losing, decision-making capacity due to illness, disability, cognitive decline or substance dependency.
• No valid Vorsorgeauftrag (advance power of attorney) or Patientenverfügung (patient directive) exists, or the existing instrument does not cover the situation.
• The person’s health, finances or personal welfare are at demonstrable risk and informal family support is insufficient.

Anyone with a legitimate interest may file an application. The KESB may also open proceedings on its own initiative, or following a report from a hospital, social services, police or another public authority.

Eligibility and Prerequisites for a KESB Deputyship

Who qualifies for a protection measure?

Under ZGB Art. 390, a deputyship may be established for any adult who, owing to a mental disability, a mental disorder, or a similar condition of weakness, is wholly or partly unable to manage their own affairs. The test is functional: it asks whether the person can, in practice, handle the specific tasks at issue, personal care, medical decisions, financial management, or legal transactions.

Who can apply?

• Relatives and close persons, spouses, registered partners, children, siblings or any person with a close personal relationship.
• Healthcare professionals, treating physicians, hospital social workers and nursing-home staff may file a report or formal application.
• Public authorities, social-welfare offices, police, tax authorities and other cantonal agencies may refer cases.
• The affected person themselves, an individual who recognises the need for support may apply directly.
• KESB (ex officio), the authority may initiate proceedings whenever it becomes aware of a potential need.

Jurisdiction and venue

The competent KESB is the one at the place of domicile of the affected person. If domicile is disputed or the person has recently moved, the KESB at the last established domicile generally retains jurisdiction until the matter is resolved. For foreign nationals domiciled in Switzerland, Swiss KESB rules apply; for Swiss nationals living abroad, the 2026 cross‑border framework (see below) governs cooperation with foreign authorities.

Urgent and interim measures

Where delay would cause serious harm, for example, an elderly person at immediate risk of financial exploitation, the KESB may order interim measures within days or even hours. An involuntary placement (fürsorgerische Unterbringung) may also be ordered by a designated physician on an emergency basis, subject to KESB review within a short statutory window.

How to Apply for Adult Protection in Switzerland: Step‑by‑Step Procedure

The adult protection procedure follows a broadly consistent pattern across all cantons, though local practice varies in detail and speed. Below is the standard sequence for requesting a KESB deputyship.

Step 1, Prepare the application and gather evidence

Begin by assembling a clear, concise written application addressed to the KESB at the affected person’s place of domicile. The application should include:

• Your full name, address, telephone number and relationship to the affected person.
• The affected person’s full name, date of birth, address and civil status.
• A factual summary of the concerns, specific incidents, observed decline in capacity, financial risks or safety issues.
• A statement of what type of protection you believe is needed (e.g., financial management, medical decision-making, housing decisions).
• Whether you are proposing a specific person as deputy, or requesting that the KESB appoint a professional deputy.

At this stage, obtain a current medical certificate or specialist capacity report from the treating physician or psychiatrist. The report should clearly address the person’s decision-making capacity and functional limitations. Best practice is to ensure this report is dated no more than two to four weeks before the application is filed. Attach any supporting evidence, hospital discharge summaries, police incident reports, bank statements showing unusual activity, or correspondence from care providers.

Some cantons provide standardised application forms (available on cantonal KESB websites). Where no form exists, a well-structured letter achieves the same purpose.

Step 2, File the application with the local KESB

Submit the application, together with all supporting documents, to the KESB of the affected person’s canton of domicile. Most KESB offices accept applications by post; some also accept submissions in person or electronically. Upon receipt, the KESB will:

• Open a clarification file and assign a case officer.
• Acknowledge receipt (usually within a few working days).
• Notify the affected person that proceedings have been initiated.
• Contact the applicant if further information or documents are needed.

The affected person has the right to be heard, to inspect the file, and to retain legal counsel at any stage. If the KESB identifies an immediate risk, it may order interim protective measures simultaneously, for example, blocking bank accounts or arranging temporary care placement.

Step 3, KESB investigation and assessment

The clarification phase is the core of the adult protection procedure. The KESB gathers evidence from multiple sources to form a complete picture:

• Medical or psychiatric expert opinion, the KESB may commission an independent assessment if the submitted medical certificate is insufficient or contested.
• Interviews, the affected person, the applicant, close family members, care providers and other relevant parties may be interviewed.
• Home visits, in many cantons, a social worker or KESB officer conducts a home visit to observe living conditions.
• Third-party inquiries, the KESB may contact banks, landlords, social services or foreign authorities (in cross-border cases) for information.

The investigation typically takes between two and twelve weeks, depending on the canton, the complexity of the case, and whether foreign evidence needs to be collected. The affected person and the applicant may submit additional evidence or written statements during this phase.

Step 4, KESB decision and appointment of deputy

Once the investigation is complete, the KESB issues a formal written decision. If a protection measure is ordered, the decision will specify:

• The type of deputyship and its exact scope (which areas of life are covered).
• The identity of the appointed deputy, this may be a family member, a professional fiduciary, or an official deputy from the cantonal deputyship office.
• Reporting obligations, the deputy must submit periodic reports and accounts to the KESB (typically annually).
• Any restrictions on the affected person’s legal capacity (e.g., inability to enter certain contracts without the deputy’s consent).

The decision is served on the affected person, the applicant and any other parties. It includes instructions on how to lodge an appeal.

Documents Needed for a KESB Deputyship Application

A well-prepared application significantly shortens the adult protection procedure. The table below lists the documents typically required or strongly recommended. Requirements may vary slightly by canton, so applicants should check with the relevant KESB office.

Timeline and Key Deadlines for the Adult Protection Procedure

There is no single national deadline for the KESB to reach a decision, and timelines vary considerably by canton and case complexity. The following benchmarks are drawn from published cantonal guidance and reflect typical ranges rather than guaranteed timeframes.

Clarification and investigation phase

Once the KESB opens a file, the clarification phase, during which the authority gathers medical reports, conducts interviews and possibly arranges home visits, normally takes between two and twelve weeks. Straightforward cases (clear medical evidence, no disputed facts, a willing deputy candidate) are resolved more quickly. Cases involving multiple expert reports, contested family dynamics, or cross-border evidence collection can extend this phase significantly.

Decision timeline

The KESB typically issues its written decision within four to twelve weeks of the application being filed. In cantons with heavy caseloads, or where expert backlogs exist, the upper end of this range is common. Urgent cases, particularly those involving immediate risk to health or finances, may be decided within days under the interim-measures framework.

Appeal deadlines

The affected person and other parties with standing generally have 30 days from service of the KESB decision to lodge an appeal with the cantonal administrative court. This deadline is strict in most cantons, and failure to act within the window ordinarily extinguishes the right to appeal at that level. Some cantons provide for extraordinary remedies in limited circumstances (e.g., where the party was unable to act due to incapacity), but these are rare and require specialist legal advice.

Best-practice timing for applicants

To minimise delay, applicants should aim to have the medical certificate and key supporting documents ready before filing. Ideally, the application should be submitted within two to three weeks of the triggering event (e.g., a hospital admission revealing incapacity, a significant financial loss, or a noticeable deterioration in daily functioning). Early preparation and complete documentation can reduce the KESB’s clarification time by several weeks.

Costs and Fees for a KESB Deputyship in Switzerland

Costs are one of the most frequently raised concerns about the adult protection procedure, and wide inter-cantonal variation makes it difficult to give a single figure. The table below provides indicative ranges; applicants should always confirm current fees with the relevant KESB.

Who pays guardian and deputy fees?

The default rule under Swiss law is that the costs of the proceedings and the deputy’s remuneration are borne primarily by the affected person, provided they have sufficient means. The KESB allocates costs in its decision and may draw on the person’s assets or income to cover them. Where the affected person lacks means, the canton (or in some cases the municipality) bears the costs.

Relatives who apply for a measure are not normally required to pay the affected person’s costs. However, a private (family-member) deputy who incurs out-of-pocket expenses is entitled to reimbursement from the affected person’s estate, subject to KESB approval. The specific tariff rules (cantonal KESV or KESR ordinances) set out the hourly rates, flat fees and expense categories that apply in each canton.

What Changes in 2026: Cross‑Border Adult Protection Update

Effective 1 January 2026, updated federal guidance from the Federal Office of Justice (BJ) clarifies the recognition and cooperation framework between Swiss KESB authorities and their foreign counterparts. The changes are particularly relevant to cases involving foreign nationals domiciled in Switzerland, Swiss nationals living abroad, and situations requiring foreign evidence or the transfer of guardianship across borders.

Key practical effects of the 2026 update include:

• Streamlined recognition. Foreign protection measures from Hague Convention countries benefit from clearer, faster recognition pathways within Switzerland.
• Evidence and legalisation. Practical guidance now specifies which documents require Apostille, which may be accepted under simplified arrangements, and how the KESB should handle translations, reducing delays in cross-border evidence gathering.
• Contact points. The BJ has published updated contact points for international cooperation, facilitating direct communication between Swiss KESB offices and foreign adult-protection authorities.

For applicants with cross-border elements, the 2026 framework is expected to reduce processing times and lower the administrative burden of obtaining and authenticating foreign documents. Industry observers expect that the most immediate benefit will be felt in cases involving EU/EFTA nationals, where institutional cooperation channels are already well established.

Common Pitfalls and How to Avoid Them

• Weak or outdated medical evidence. A vague or stale medical certificate is the single most common reason for delay. Obtain a current specialist capacity report, dated within two to four weeks of filing, that directly addresses the person’s functional limitations.
• Wrong jurisdiction. Filing with the KESB of the wrong canton wastes time. Confirm the affected person’s registered domicile before submitting.
• Incomplete foreign-document authentication. Foreign documents submitted without Apostille or consular legalisation, or without certified translation, will be returned or disregarded. Prepare these well in advance.
• Choosing an unsuitable deputy. Proposing a family member who has a conflict of interest (e.g., shared financial dealings with the affected person) may lead the KESB to appoint an independent professional deputy instead. Consider suitability carefully before nominating.
• Ignoring cost-contribution rules. Failing to account for the affected person’s means, or assuming the state will pay, can result in unexpected cost allocations. Clarify the financial position early and discuss it with the KESB.
• Missing the appeal deadline. The 30-day appeal window is typically strict and non-extendable. If you intend to challenge a KESB decision, instruct a lawyer immediately upon receiving the decision.
