Three points to know

Before and after calculating

Representation stays within that branch's share

If a child died before the person leaving the estate, that child's children or spouse may take the child's place. More representatives do not increase the branch's total share.

Only child and grandchild branches are covered

The spouse is calculated as receiving 1.5 times the share of one child. Within a predeceased child's branch, that child's spouse likewise receives 1.5 times the share of one grandchild. All grandchildren are assumed to be alive and eligible to inherit.

Disputes require individual review

Wills, lifetime gifts, care contributions, debts or renunciation may change the actual shares. If relationships are complex or disputed, take the documents to a legal professional. This calculation is not legal advice or representation.

Calculation basis and official sources
