• An addendum that only adds rules on the use of AI tools, without changing the price, does not normally carry separate stamp duty. The stamp duty on the existing agreement stays as it is.
• If you use this Addendum at the same time to increase the fees of a service or hire-of-work agreement, additional duty is payable on the increase. Put fee changes in a separate amendment so that the position is clear.

• Check the amendment clause of the existing agreement. If it requires a particular form, such as signature by two directors or the company seal, sign this Addendum in the same way.
• Staple or attach this Addendum to both signed copies of the existing agreement, or keep the signed PDFs in the same folder, so that anyone who reads the agreement also sees the Addendum.
• The Addendum applies to work from … (Clause 1.1). Do not backdate it to cover work already done; agree separately if earlier work needs to be checked.

• Keep the approved list of AI tools up to date. Approve new tools by email so that there is a written record (Clause 3.1).- Ask the Supplier for its list of AI tools at the start and from time to time (Clause 3.1).- The Supplier may not use AI tools to produce the work (Clause 3.1). Make sure the Supplier's team, including subcontractors, knows this (Clause 3.2).
• Free and personal versions of AI tools often allow the provider to use what you type for training. Only business or enterprise versions with training switched off meet Clause 4.1.
• Read the AI disclosure that comes with each deliverable (Clause 7.1) and check the parts made with AI more carefully, especially facts, references and figures.

• No personal data may go into AI tools, because AI tools may not be used for the work (Clause 4.2).- When personal data is put into an AI tool, the tool provider becomes a sub-processor. Ask the Supplier which providers are used and where they process data (Clause 4.2), and check that your privacy notice covers it.- The Supplier must remove names and other identifying details before using AI with your data (Clause 4.2). If a task genuinely needs personal data, agree it in writing first.
• If the Supplier reports an AI-related incident, decide quickly whether you must notify the Personal Data Protection Committee, which in most cases must be done within 72 hours after you become aware of the breach (Clause 10).

• Material produced by an AI tool without enough human creative work may not be protected by copyright in Thailand or abroad. For logos, books, software and other work you need to protect, ask for human-made core elements (Clause 8.2).

• Keep the signed Addendum with the existing agreement, the approved tool list, the AI disclosures received with deliverables and any incident reports.
