Client and Architect Agreement 2009 (CAA 2009)

The CAA2009 has now been withdrawn from sale. The CAA2019 is a major revision and we strongly recommend its use to better protect your interests, avoid misunderstandings or disputes and have a contract that is compliant with the Codes of Conduct in each state and territory.

The digital version of the CAA2019 is now available to all Institute members, with access to Acumen, as a membership benefit. Hardcopy versions are also available at 

The Client and Architect Agreement 2009 (CAA2009) can be used for projects of all sizes and complexity. It is published with a comprehensive user guide, proforma guide letters and a sample of a completed agreement. The CAA2009 can be completed and amended by hand and the schedules and signing pages are also available digitally.

The User Guide is intended to give you, the architect, guidance on the contents and effect of the CAA2009 and suggestions on how you can complete the details in the contract’s schedules. The User Guide may also be used to assist the client to correctly complete the necessary details and sign the agreement.
