How Long Does Lex Koller Approval Take?

Standard processing time

For a complete and straightforward application, Lex Koller authorisation from the Canton of Vaud typically takes four to eight weeks from the date of submission. This assumes the application is complete, the property meets all requirements, and quota is available.

The notary will submit the application as early as possible in the transaction process — often at the same time as the purchase contract is signed. This minimises the delay between offer acceptance and completion.

Factors that can extend the timeline

Several factors can extend the processing time. An incomplete application — missing documents or unclear information — will be returned for correction, adding weeks to the process. Complex ownership structures (trusts, companies, multiple buyers) may require additional review. Properties with unusual characteristics or historical authorisation conditions may also require more detailed assessment.

The most significant delay factor is quota exhaustion. If the annual quota for the Canton of Vaud is exhausted when the application is submitted, the authorisation will be deferred to the following year — a delay of potentially twelve months.

How to minimise delays

The most effective way to minimise delays is to work with an experienced notary who is familiar with the Lex Koller process and can prepare a complete, accurate application at the outset. Buyers should also verify quota availability before making an offer, so that a quota-related delay does not come as a surprise.

Buyers should also ensure that all required documents are prepared in advance — particularly passport copies, residence evidence and any corporate documentation if the purchase is through a company structure.

Contractual provisions for timing

Purchase contracts for Lex Koller-regulated properties typically include a condition precedent (condition suspensive) that makes completion conditional on authorisation being granted. The contract will specify a long-stop date by which authorisation must be obtained, with provisions for extension if the quota is exhausted.

Buyers and sellers should agree on these provisions clearly before signing the contract. An experienced notary will draft appropriate clauses to protect both parties.

• Standard processing time: four to eight weeks for a complete application
• Incomplete applications and complex structures can extend the timeline
• Quota exhaustion can defer authorisation by up to twelve months
• Work with an experienced notary to prepare a complete application
• Purchase contracts should include appropriate conditional clauses
