The notary does not represent your interests.

Buying property in the canton of Zurich is one of the largest transactions of your life. The notary authenticates the agreement and must remain neutral. An unfavourable clause may only become apparent when someone reads the contract from your perspective.

Notarisation is not buyer representation

The notary ensures formal validity under Article 216 of the Swiss Code of Obligations. Assessing whether the contract is fair to you as the buyer remains your responsibility.

Critical clauses lie in the details

Exclusions of warranties, transfer of benefits and risk, inventory, existing leases and easements: individual clauses determine who bears a hidden risk.

Before signing, not afterwards

After notarisation, the purchase is binding. Terralex’s team reads the draft while there is still time to negotiate changes.

View all questions
Does the review replace the notary?+

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.

What will I receive?+

A written assessment explaining which clauses are standard or favourable, which are critical and what to renegotiate before signing. Full negotiation support includes ongoing written assistance. Personal consultations and direct negotiations are reserved for Premium.

When should I contact Terralex?+

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.

Which properties and regions do you cover?+

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.

What does the review cost?+

Contract check CHF 250, complete purchase review CHF 500, full negotiation support CHF 1'000, Premium purchase support CHF 2'000. All prices are fixed and include VAT.
