AI summary

A Sale and Purchase Agreement is the legally binding contract for buying or selling a property in New Zealand. It details the price, deposit, chattels, and key dates.

Agreements can be conditional, depending on factors like securing finance or a satisfactory building report. Once all conditions are met by the unconditional date, the deal is locked in. The sale is finalised on the settlement date.

Failing to meet conditions can have serious financial consequences. It is crucial to get legal advice before signing.
