AI Legal Letter Drafting: Without Prejudice Offers, Cease and Desist, and Section 62 Notices

April 2026 · 10 min read

AI legal letter drafting is the process of using artificial intelligence to generate structured legal correspondence — including without prejudice settlement offers, cease and desist demands, and costs disclosure notices — from a lawyer's instructions, producing a first draft that follows Australian legal conventions and formatting standards in minutes rather than the 30-60 minutes typically required for manual drafting. The lawyer reviews, edits, and finalises the letter before sending.

Legal correspondence is one of the most repetitive categories of legal work. While every matter has unique facts, the structural elements of common letter types — the opening, the legal basis, the demand, the deadline, and the consequences — follow predictable patterns. A 2024 survey by Thomson Reuters found that Australian lawyers spend an average of 4.3 hours per week drafting correspondence, with much of that time spent on letters that follow standard formats.

AI does not replace the lawyer's judgment about what to say. What it eliminates is the time spent structuring the letter, applying the correct formatting, and inserting standard legal language that appears in virtually every letter of that type.

Without Prejudice Offers

A without prejudice offer is a settlement proposal made during or before litigation that is protected from disclosure to the court under the without prejudice privilege. The privilege encourages parties to negotiate freely by ensuring that concessions made during settlement discussions cannot be used against them if the negotiations fail and the matter proceeds to trial.

Legal basis

The without prejudice privilege is recognised at common law and codified in s 131 of the Evidence Act 1995 (Cth) and equivalent state legislation. The privilege attaches to communications made in a genuine attempt to settle a dispute. The letter must be clearly marked "Without Prejudice" (or "Without Prejudice Save as to Costs" for Calderbank offers) and must constitute a genuine attempt to resolve the dispute rather than a tactical manoeuvre.

Calderbank offers

A Calderbank offer (named after Calderbank v Calderbank [1975] 3 All ER 333) is a specific type of without prejudice offer that is marked "Without Prejudice Save as to Costs." This means the offer cannot be disclosed to the court on the substantive issues, but it can be disclosed on the question of costs after judgment. If the opposing party rejects the offer and subsequently obtains a result less favourable than the offer, the court may order indemnity costs against them from the date the offer was made.

Under the Civil Procedure Act 2005 (NSW), the court has discretion to consider Calderbank offers when making costs orders. Similar provisions exist in other Australian jurisdictions. The strategic value of a well-timed Calderbank offer can be significant — it shifts costs risk to the opposing party and creates pressure to settle.

What AI drafts

When drafting a without prejudice offer, AI generates the letter with the correct heading ("Without Prejudice" or "Without Prejudice Save as to Costs"), a summary of the dispute and the parties' respective positions, the specific terms of the offer (monetary amount, non-monetary terms, conditions), a deadline for acceptance (typically 14-28 days), the consequences of non-acceptance (reference to costs consequences for Calderbank offers), and a clear statement that the offer is made in genuine attempt to resolve the dispute.

The lawyer's review must ensure the offer terms match the client's instructions exactly, the cost consequences language is appropriate for the jurisdiction and procedural rules, and the offer is open for a reasonable period.

Cease and Desist Letters

A cease and desist letter is a formal demand that the recipient stop specified conduct that the sender alleges is unlawful — typically trademark infringement, copyright infringement, defamation, or breach of contract. The letter is not a court order and has no independent legal force, but it serves several strategic purposes.

Strategic value

First, the letter creates a written record of the demand, which is relevant if proceedings follow. A court considering an injunction application will note whether the plaintiff first attempted to resolve the matter by correspondence before resorting to litigation. Second, the letter puts the recipient on notice — particularly important in intellectual property matters where the recipient's knowledge of the infringement is relevant to the available remedies. Under the Trade Marks Act 1995 (Cth), for example, additional damages may be available where the infringer had knowledge of the registration.

Third, a well-drafted cease and desist letter often resolves the matter without litigation. According to a 2023 study by the Intellectual Property Research Institute of Australia, approximately 65% of trademark infringement disputes that begin with a cease and desist letter are resolved without court proceedings.

What AI drafts

For a cease and desist letter, AI generates an identification of the sender and the legal right being asserted (registered trademark, copyright work, contractual right), a description of the infringing conduct with specific details (dates, URLs, product descriptions), the legal basis for the claim (specific legislation, registration numbers, contractual clauses), the demand (cease the specified conduct, remove infringing material, provide undertakings), a deadline for compliance (typically 7-14 days), and the consequences of non-compliance (court proceedings, injunctive relief, damages, costs).

The lawyer must verify that the legal right being asserted is valid and current (trademark registrations expire, copyright duration varies), that the alleged infringing conduct is accurately described, and that the remedies threatened are actually available under the applicable law.

Section 62 Notices (Costs Disclosure)

A Section 62 notice — technically a costs disclosure under s 174 of the Legal Profession Uniform Law (NSW and Victoria) or equivalent provisions in other states — is a mandatory disclosure that lawyers must provide to clients about the costs of legal services. The specific section number varies by jurisdiction, but the obligation is universal across Australian states and territories.

What must be disclosed

The costs disclosure must include the basis on which legal costs will be calculated (hourly rates, fixed fees, or a combination), an estimate of the total legal costs or, if an estimate is not possible, a range of likely costs and an explanation of why a precise estimate cannot be given, the client's right to negotiate a costs agreement, the client's right to receive an itemised bill, the client's right to seek costs assessment, and information about the firm's dispute resolution process for billing complaints.

Under the Legal Profession Uniform Law, failure to provide adequate costs disclosure can result in the costs being reduced or disallowed entirely if the client challenges the bill through costs assessment. The costs disclosure must be provided before or as soon as practicable after the lawyer is retained.

What AI drafts

AI generates a costs disclosure notice with all required elements pre-populated based on the lawyer's input (hourly rates, estimated range, matter type). The lawyer reviews to ensure the cost estimates accurately reflect the likely scope of work, the billing basis matches the firm's standard terms, all required statutory information is included for the relevant jurisdiction, and the disclosure is provided within the required timeframe.

The AI Drafting Workflow

Regardless of the letter type, the AI-assisted drafting workflow follows a consistent pattern that produces usable first drafts in 2-5 minutes.

Step 1: Select the letter type. The lawyer chooses from the available letter types — without prejudice offer, cease and desist, costs disclosure, or general correspondence.

Step 2: Input the key details. The lawyer provides the matter-specific information: party names, the nature of the dispute or legal right, the specific terms or demands, relevant dates, and any jurisdiction-specific requirements.

Step 3: AI generates the draft. The tool produces a complete letter with proper formatting, legal language appropriate to the letter type, and all structural elements included. The draft uses formal Australian legal correspondence conventions including the firm's reference, the addressee details, "Dear Sir/Madam" or named addressee, and proper sign-off.

Step 4: Lawyer review and edit. The lawyer reviews every element of the letter. This step is critical — the lawyer must ensure factual accuracy (AI may infer or assume facts not provided), legal accuracy (AI may state legal propositions that need refinement), tone appropriateness (the letter may need to be more or less aggressive depending on the strategy), and that the letter reflects the client's specific instructions.

Step 5: Send and bill. The finalised letter is sent, and a billing entry is generated for the drafting time.

Quality Control: What to Watch For

AI-drafted legal letters are first drafts, and certain errors appear more frequently than others.

Overstated legal positions. AI may assert legal rights more broadly than is warranted. A cease and desist letter claiming trademark infringement should be reviewed against the actual scope of the registered mark — the AI may not correctly assess whether the alleged infringing use falls within the mark's specification.

Generic deadline periods. AI typically inserts a 14-day deadline because that is the most common period. Some situations warrant shorter deadlines (urgent injunctive relief) or longer periods (complex commercial negotiations). The lawyer should adjust the deadline to match the strategic context.

Missing jurisdictional nuances. Costs disclosure requirements vary between states. A notice drafted for NSW may not include all required elements for Queensland or Western Australia. Always verify against the specific legislation that applies in the relevant jurisdiction.

Tone mismatches. AI tends toward formal, measured language. Sometimes a letter needs to be sharply worded to convey urgency; other times it needs to be conciliatory to preserve a commercial relationship. The lawyer should adjust the tone to match the strategic objective.

Can AI draft a without prejudice offer for Australian lawyers?

Yes. AI generates a structured letter with the correct heading, dispute summary, offer terms, acceptance deadline, and Calderbank cost consequences language. The lawyer must review to ensure the offer terms match the client's instructions exactly and that the costs consequences language is appropriate for the specific jurisdiction and procedural rules. The strategic decision about when and at what amount to make the offer remains entirely with the lawyer.

What is a Section 62 notice under Australian law?

It refers to the costs disclosure obligation under the Legal Profession Uniform Law (NSW and Victoria) or equivalent state legislation. Lawyers must inform clients in writing about the basis of legal costs, provide an estimate or range, and advise clients of their rights to negotiate costs, receive itemised bills, and seek costs assessment. The specific section number varies by jurisdiction — the obligation is commonly referred to as "Section 62" but the applicable provision depends on which state's legislation governs. AI can generate the standard notice, but the lawyer must ensure cost estimates and billing terms are accurate.

Is a cease and desist letter legally binding in Australia?

No. A cease and desist letter is a formal demand, not a court order. It has no independent legal force — the recipient is not legally compelled to comply. Its value is strategic: it creates a written record of the demand, puts the recipient on notice of the alleged wrongful conduct (relevant for remedies in IP cases), and demonstrates willingness to litigate. Approximately 65% of trademark disputes that begin with a cease and desist letter resolve without court proceedings.
