The waiver agreement

The inheritance agreement is a major legal tool in Swiss inheritance law, enabling the individual to organize his or her inheritance during his or her lifetime. Among the various forms of inheritance agreements, the waiver agreement occupies a special place. It enables a prospective heir to waive in advance all or part of his or her inheritance rights, generally in return for something in return. This arrangement offers great flexibility in estate planning, but also raises complex questions in terms of validity and legal effects. Its use requires a thorough understanding of the Swiss legal framework and its concrete implications for families.

Definition and legal framework of the waiver agreement

The waiver agreement is a legal act by which a prospective heir waives in advance all or part of his or her future inheritance rights. It falls within the broader framework of inheritance agreements, governed by Articles 494 et seq. of the Swiss Civil Code (CC).

Unlike a will, which is a unilateral act, a waiver agreement is a bilateral contract between the grantor (future deceased) and the grantee (heir presumptive). It must be concluded in authentic form before a notary, in the presence of two witnesses.

The main characteristics of the waiver agreement are:

• It is irrevocable, unless mutually agreed by the parties
• It may relate to all or part of the estate
• It may be free of charge or for a fee (in return for something in return)
• It only takes effect upon the death of the person making the agreement

The waiver agreement thus makes it possible to exclude an heir from the estate, which can prove useful in various family or patrimonial situations. It offers greater freedom in the organization of the estate than ordinary legal provisions.

Legal basis in Swiss law

The waiver agreement is specifically provided for in Article 495 CC, which states: “The testator may conclude a waiver of inheritance agreement with one of his heirs, whereby the latter renounces his status as heir in return for compensation or without compensation.”

This provision is part of the chapter of the Civil Code devoted to inheritance agreements. It must be read in conjunction with the other articles relating to inheritance agreements, in particular Article 494 CC on the authentic form and Article 496 CC on the effects of the agreement.

Conditions of validity of the waiver agreement

To be valid, a waiver agreement must meet several strict conditions of substance and form:

Substance

• Capacity of the parties: The person making the waiver and the person waiving the right must have the capacity to dispose of their rights, i.e. they must be of legal age and capable of discernment.
• Free and informed consent: Both parties must freely consent to the agreement, without any vitiating factors (error, fraud, well-founded fear).
• Lawful and specific object: The waiver must relate to identified future inheritance rights.
• Lawful cause: The reason for the agreement must not be contrary to public order or morality.

Formal requirements

• Authentic form: The agreement must be drawn up before a notary, in the presence of two witnesses (art. 512 CC).
• Minimum content: The deed must specify the identity of the parties, the subject of the waiver and any consideration.
• Signature of the parties: The person making the disposition and the person waiving the right must sign the deed.

Failure to comply with these conditions may result in the nullity of the waiver agreement. It is therefore essential to ensure that they are complied with when the deed is concluded.

Special features for heirs entitled to a reserved portion

When the renouncing party is an heir entitled to a reserved portion (descendant, spouse or registered partner), specific rules apply:

• The waiver of the reserved portion must be express and cannot be presumed
• It cannot infringe on the rights of the other heirs entitled to a reserved portion
• It may be subject to judicial review in the event of manifest lesion (art. 497 CC)

These rules are designed to protect heirs entitled to a reserved portion against hasty or disadvantageous renunciations.

Legal effects of the waiver agreement

The waiver agreement has significant legal effects, both for the renouncing party and for the other heirs and the testator:

Effects for the renouncing party

• Loss of status as heir: The renouncing party loses his status as heir for the share concerned by the renunciation.
• Exclusion from the inheritance: He no longer participates in the division of the inheritance for the renounced share.
• Loss of the right of reduction: He can no longer act in reduction against the liberalities made by the deceased.
• Transfer to descendants: Unless otherwise stipulated, the waiver extends to the descendants of the person making the waiver.

Effects for the other heirs

• Increase in their shares: The share of the person making the waiver increases that of the other heirs of the same lineage.
• Change in the reserves: The waiver may result in an increase in the reserves of the other heirs.

Effects for the testator

• Greater freedom of disposition: The testator may freely dispose of the relinquished share.
• Irrevocability: The testator can no longer unilaterally revoke the agreement.

It should be noted that these effects only occur upon the death of the testator. Until that time, the relinquishing party retains his status as heir presumptive.

Special case: conditional waiver

The waiver agreement may include conditions precedent or subsequent. For example, the waiver may be conditional on the survival of other heirs or on the allocation of certain assets to third parties. In this case, the effects of the agreement will depend on whether or not the condition is met.

Advantages and disadvantages of the waiver agreement

The waiver agreement has several advantages and disadvantages that should be carefully weighed before committing to it:

Advantages

• Flexibility in estate planning: Allows for the adaptation of inheritance to complex family situations.
• Conflict prevention: Can avoid future disputes by clarifying the inheritance situation during the testator’s lifetime.
• Tax optimization: Can reduce the overall tax burden of the inheritance.
• Protection of family assets: facilitates the transfer of family businesses or specific assets.
• Legal certainty: offers greater stability than testamentary dispositions, due to its irrevocability.

Disadvantages

• Irrevocability: the agreement cannot be modified unilaterally, even if circumstances change.
• Complexity: requires an in-depth analysis of the long-term consequences.
• Cost: Authentication and legal advice can represent a significant cost.
• Risk of loss: The renouncer may find themselves at a disadvantage if the value of the estate changes significantly.
• Impact on the family: Can create tensions or inequalities between heirs.

The use of a waiver agreement must therefore be carefully considered, taking into account the family situation, assets and objectives of the person making the disposition.

Comparison with other estate planning tools

The waiver agreement differs from other estate planning tools such as the will or inter vivos donation:

• Will: Unlike the agreement, the will is revocable and unilateral.
• Inter vivos donation: The donation takes effect immediately, whereas the agreement only takes effect upon death.
• Agreement as to succession by attribution: Aims to attribute specific assets, whereas the agreement to renounce excludes an heir.

The choice between these different tools will depend on the objectives pursued and the specific situation of each family.

Current and practical implications of the waiver agreement

The waiver agreement plays a significant role in contemporary Swiss inheritance practice, meeting a variety of needs:

Frequent contexts of use

• Transfer of family businesses: Allows capital to be concentrated in the hands of a single heir.
• Blended families: Facilitates the balancing of children from different relationships.
• Compensation for previous advantages: Rebalances the situation of heirs who have already benefited from significant donations.
• Protection of the surviving spouse: Increases the spouse’s share of the inheritance by excluding other heirs.

These uses reflect the evolution of family and wealth structures in Switzerland.

Current legal challenges

The practice of waiver agreements raises several current legal issues:

• Interpretation of conditional clauses: The courts are regularly called upon to clarify the scope of complex conditions.
• Relationship with private international law: The increased mobility of families raises questions of recognition abroad.
• Protection of vulnerable heirs: The risk of family pressure on heirs in precarious situations is a matter of concern.
• Review for lesion: The assessment of lesion in a volatile economic context remains a delicate matter.

These challenges require specialized legal expertise to secure waiver agreements.

Role of legal professionals

Given the complexity of waiver agreements, it is often essential to consult legal professionals:

• Notaries: Play a central role in the drafting and authentication of the agreement.
• Specialist lawyers: Advise on the long-term legal and fiscal implications.
• Accountants: Assess the financial and fiscal impact of the agreement.

These professionals work together to offer a comprehensive approach, taking into account legal, fiscal and patrimonial aspects. Their intervention makes it possible to secure the agreement and optimize its effects.

Legislative and case law developments

Swiss inheritance law is undergoing changes that impact the practice of the waiver agreement:

• Reform of inheritance law: Recent amendments to the Civil Code have relaxed certain rules, offering more freedom in estate planning.
• Case law of the Federal Court: Several recent rulings have clarified the interpretation of inheritance agreements, particularly with regard to revision for lesion.
• International harmonization: Efforts to harmonize inheritance law at the European level indirectly influence Swiss practice.

These developments underline the importance of constant legal monitoring for practitioners of inheritance law.

Ultimately, the waiver agreement remains a powerful tool for estate planning under Swiss law. Its judicious use, supervised by competent professionals, makes it possible to effectively meet the needs of modern Swiss families in terms of wealth transfer. The complexity of this legal instrument and its long-term implications fully justify the use of in-depth legal expertise.
