How to make a will online in Switzerland?

What is legally possible, what is not, and how to choose the right solution.

Drafting a will using online tools has grown in Switzerland in recent years. Specialized platforms, AI generators, and digital services promise simplicity and speed.

From a legal standpoint, however, digital technology does not create a new form of will: He only assists in the preparation of an act which remains strictly governed by Swiss law.

This guide explains what is truly valid, the differences in purpose between existing solutions, and common mistakes to avoid.

Forms of Will Recognized under Swiss Law

Swiss law recognizes three forms of will:

• le holographic will (manuscript),
• le public will (authentic),
• le oral willreserved for exceptional circumstances.

None of these forms are “digital”.

Online tools are only used upstream, as an aid to reflection or structuring.

The holographic will: the only form compatible with online preparation

A holographic will is the only form that can be prepared using an online tool, under one essential condition: the final text must be entirely handwritten by the testator.

This requirement stems from theArticle 505 of the Swiss Civil Code, which requires that the holographic will be:

• written entirely in the testator's own hand,
• dated (day, month, year),
• sign.

A printed document, even if signed, is legally null.

Reputable platforms therefore provide a customized template that serves only as a support, which the tester must then copy manually, without erasures or additions.

The real role of online platforms

An online will service does not replace the law or a notary. Its role is limited to:

• to structure the wills,
• to draw attention to the rules of forced heirship,
• improve writing clarity,
• reduce the risk of obvious errors.

The legal value of a will depends exclusively on:

• strict adherence to handwritten requirements,
• compliance with Swiss inheritance law.

Legal validation: a security factor, not a formality

A handwritten will, even if correctly copied, can be contested if it contains:

• ambiguous wording,
• violations of the forced heirship rules,
• internal contradictions,
• imprecise designations of heirs or legacies.

A review by a Swiss lawyer constitutes a risk reduction measure, but does not give the document the probative force of an authentic instrument.

Its main aim is to prevent disputes, not to guarantee indisputability.

Holographic wills prepared online and authentic wills: two distinct uses

Comparing a will prepared online and an authentic will solely on the basis of price or duration is legally reductive.
These two instruments meet different needs.

Handwritten will (prepared online)

• private act
• written and kept by the testator,
• normal probative force,
• suitable for simple to medium situations,
• sensitive to disputes in the event of family conflict.

Authentic Will

• public document drawn up by a notary
• official conservation,
• high probative value,
• professional responsibility of the notary,
• suitable for complex situations or situations with high heritage stakes.

A notarial will is generally preferred when:

• The family situation is complex.
• The heritage is significant or structured.
• The risk of dispute is high.
• Legal certainty takes precedence over flexibility.

Cost and time: how to understand them correctly

It is commonly observed that:

• A handwritten will prepared with an online tool involves a lower cost.
• An authentic will requires more formal procedures. 

However:

• Notary fees vary considerably depending on the canton and the complexity of the case.
• A simple, authentic will can be drawn up quickly.
• The price reflects responsibility, probative value and preservation, not just drafting.

The determining criterion is therefore not the price or the time frame, but the level of legal security sought.

Registration with the Central Register of Wills

Regardless of the chosen format, the recording at Central Register of Wills is highly recommended.

This register, managed by the Swiss Chamber of Notaries, allows the authorities to verify the existence of a will upon death.
Only a legal professional can carry out this registration.

Without registration:

• The will may never be found.
• It may be discovered too late.
• Its validity can be more easily challenged.

Limitations of free AI generators

AI generators can provide a basis for reflection, but have structural limitations:

• references to foreign laws,
• lack of responsibility
• generic formulations,
• a thorough lack of understanding of Swiss reserve rules

They do not constitute legal validation or a guarantee of conformity.

Best practices for a valid handwritten will

1. Establish an accurate inventory of the heritage
2. Clearly identify each beneficiary
3. Strictly respect the reserved portion of the estate.
4. Appoint an executor of the will if necessary
5. Copy the entire text by hand
6. Date and sign without omission.

Conclusion

An online will does not replace a notary or an authentic instrument. It is a tool for preparing a holographic will, useful when the situation is simple and the testator seeks flexibility and accessibility.

The choice between a holographic will and an authentic will should be made based on the level of complexity, the risk of conflict and the desired degree of legal security, and not solely on the basis of cost or time.
