Blended families, cohabitation and business succession

How does inheritance work in a blended family?

Blended families are among the most common and most complex succession planning situations today.

A parent may wish to:

• protect a current spouse;

• preserve the rights of children;

• take account of children from previous relationships;

• provide for stepchildren with whom strong personal bonds exist.

Swiss inheritance law does not automatically treat all these individuals in the same way.

Do stepchildren inherit automatically?

No.

Even where a stepchild has been part of the family for many years, they do not automatically become a statutory heir.​‌

To include them in the transfer of assets, it is necessary to make specific provision for this as part of your estate planning. Solutions such as a will or certain provisions in an estate plan make it possible to arrange for a transfer in their favour within the limits laid down by law.
 

How can you protect your spouse without disadvantaging your children?

This is one of the most common questions in blended family estate planning.

On the one hand, a surviving spouse may need financial security and stability.

On the other hand, children expect their future inheritance rights to be respected.

The challenge is particularly acute when the family's wealth is tied up in:

• the family home;

• investment portfolios;

• a family business.
  
  

Without proper planning, these competing interests can become difficult to reconcile.

Which tools can help balance different family interests?

Depending on the circumstances, several tools may work together:

• the matrimonial property regime;

• a marital agreement;

• a will;

• an inheritance agreement;

• usufruct rights;

• rights of residence;

• life insurance;

• pension arrangements.
  
  

In some blended families, the matrimonial property regime is even one of the main means of protecting the surviving spouse. It can help to improve their financial situation even before the rules of succession come into play, thereby reducing certain tensions between the different branches of the family.

The objective is not to favour one generation at the expense of another, but to create a balanced and transparent succession strategy.

How can you transfer a family business?

A family business cannot usually be divided in the same way as a bank account.

Where it represents a significant share of family wealth, succession planning becomes one of the most important strategic decisions a family can make.

What if only one child takes over the business?

This situation is extremely common. One child may have worked in the business for years, while the others have followed different careers.

The future owner must be able to continue operating the business successfully.

At the same time, the other heirs generally expect fair treatment.

Balancing these objectives often requires a combination of inheritance planning tools, including inheritance agreements and lifetime wealth transfers.

Why should business succession planning start early?

Business succession should rarely be handled at the last minute.

Early planning makes it possible to:

• prepare the future successor;

• evaluate the business properly;

• organise compensation between heirs;

• secure the founder’s future income;

• anticipate tax implications.

The earlier the planning begins, the more options become available.​‌

How can family disputes be reduced?

Inheritance disputes do not necessarily arise because large sums are involved.

More commonly, they result from:

• poor communication;

• unclear intentions;

• different expectations;

• insufficient planning.
  
  

Where succession plans have been discussed, documented and reviewed in advance, family members generally have a better understanding of the reasons behind the decisions that have been made.

The goal is not to eliminate every disagreement, but to reduce unnecessary uncertainty.
