Inheritance Rights of Cousins

In the event of the death of a cousin, one does not automatically receive an inheritance. Nevertheless, there are several ways to receive part or even the entire inheritance.

Cousin’s Will

If the cousin has made a will, she can in turn consider her cousins in the will. In this way, according to the last will of the cousin, one can be considered as the sole heir of the entire estate or with a certain quota (e.g. half, quarter).

Bequest / Legacy of the Cousin

Furthermore, the cousin has the possibility to leave individual objects (e.g. flower vase) or rights (e.g. right of residence in her house) to her cousins as a legacy.

Donation Mortis Causa by the Cousin

In the case of a donation mortis causa, the cousin promises her cousins the transfer of a certain part of the estate as a gift in the event of her death. The effect of the donation only occurs upon death.

In contrast to a testamentary disposition by a will or a legacy, which the cousin could change at any time, the cousin is also bound by the donation mortis causa. The donation mortis causa is a bilaterally binding contract, which can no longer be revoked unilaterally.

Care Legacy

The care legacy is a legal legacy. It is not based on a testamentary disposition of the deceased cousin, but exclusively on the basis of the law.

Cousins are entitled to a care legacy if they have cared for the cousin as follows:

Legal Succession after the Cousin

If the cousin has not made a will, the legal succession comes into effect. However, their cousins are only considered under the legal succession if the following persons (spouse and close relatives of the deceased cousin) do not exist, have already died or are lawfully excluded from the inheritance:

Subsequent Inheritance

In the case of a subsequent inheritance, the deceased appoints another person as heir, the subsequent heir. This person receives the assets after the first-appointed heir.

If the cousin was therefore determined as the heir in an earlier testamentary disposition and the cousins as subsequent heirs after the cousin, the cousins will be considered upon the death of the cousin. Depending on the type of subsequent inheritance, they will then receive the full original inheritance or only the part that the cousin has not consumed.

Substitute Inheritance

When drafting a will, a substitute heir should always be named. The substitute heir will then be considered if the appointed heir cannot inherit or rejects the inheritance.

If the cousin has therefore appointed someone who has already died or who rejects the inheritance as heir and the cousins as substitute heirs, then they will also be considered upon the death of the cousin.

Amount of the Inheritance

The amount of the inheritance or the amount of the value that ultimately remains for the cousins depends not only on the assets of the cousin, but also on the number of other heirs, legatees and beneficiaries.
