What you should know about the review.

Our reviewers read the draft from the buyer’s perspective, examine critical clauses and provide a written risk assessment with specific recommendations for renegotiation before notarisation.

No. Article 216 of the Swiss Code of Obligations requires public notarisation of property purchases. The notary must remain neutral and represents neither buyer nor seller. Terralex reviews the contract from your perspective before notarisation. The two services complement each other.

We primarily support buyers in the canton of Zurich: Zurich city, Limmattal, Goldküste, Säuliamt, Winterthur and Knonaueramt. We review detached houses, condominium apartments, building land and apartment buildings. Enquiries from neighbouring regions are considered individually. We clarify the scope of especially complex transactions in advance.

As soon as the notary or seller provides a draft, ideally three to five days before notarisation, so there is time to discuss and negotiate changes.

For particularly urgent cases, such as notarisation in less than 48 hours, contact us directly through the enquiry form. We will confirm availability promptly.
