Notarielle Beurkundung is the strictest form in German law: a notary records the parties' declarations in a deed, reads it aloud to them and has them approve and sign it. Contracts to buy German land or GmbH shares require it, and an agreement left out of the deed can leave the whole purchase void.
• Your own lawyer has approved the final text.
• Every agreement forming part of the deal, from guarantees to side letters, is in the deed.
• The reference deed was executed in advance, and you have read it.
• If your German is not sufficient, the deed is translated to you, in writing on request (§ 16 BeurkG).
• Powers of attorney and company documents meet the land registry's form (§ 29 GBO).
