AI summary

A Sale and Purchase Agreement is the legally binding contract for buying or selling a house in New Zealand. It outlines all terms, conditions, and timelines, and it is critical to get legal advice before signing.

The agreement becomes unconditional once all conditions—such as finance or a building report—are met. Key details include:

- Purchase price and deposit

- Chattels included in the sale

- The settlement date

Failing to meet conditions can cancel the deal, but defaulting on an unconditional agreement carries serious financial penalties.
