Key legal question
Whether the CHF 70,000 paid out after the donor's death was a valid inter vivos gift or part of the estate subject to back taxation and inheritance tax.
Extracted holding
No valid inter vivos gift existed; the amount remained in the deceased's estate and was properly back-taxed.
Extracted reasoning
A gift promise requires written form. An oral promise is void, and a hand-to-hand gift is impossible once the donor has died. Execution after death cannot cure the form defect because the donor can no longer express the gift will through delivery. The transfer was therefore not a valid gift during life, and the amount belonged to the estate.
