Lex Koller

Lex Koller is the common name for the Swiss federal law that restricts the acquisition of real estate by non-resident foreign individuals and companies. It aims to limit speculation and to protect the Swiss property market. In practice, it requires cantonal and federal authorisation for the purchase of second homes, building land or certain types of property by buyers without a stable residence permit (C permit) or without residence in Switzerland. In Geneva, any foreign buyer must check their eligibility and, where applicable, obtain this authorisation before signing, failing which the transaction is null and void.
