Terminating an engagement on the chartered accountant's initiative: 2026 template and guide

Quick answer. A chartered accountant may unilaterally terminate an engagement if a legitimate ground is established (persistent non-payment, conflict of interest, AML suspicion, refusal to cooperate from the client). The procedure requires a reasonable notice period (two to three months in practice), notification by registered letter with acknowledgement of receipt (LRAR), the prompt return of the documents belonging to the client and final invoicing up to the effective date. The legal framework rests on decree n° 2007-1387 (OEC Code of Conduct) and decree n° 2012-432 of 30 March 2012, supplemented by the AML duties under article L.561-2 of the French Monetary and Financial Code.

The firm-client relationship has grown more complex in recent years under three converging trends: the generalisation of electronic invoicing on 1 September 2026, the tightening of Tracfin oversight (the chartered accountancy profession transmits more than 1,800 suspicion declarations per year according to Tracfin activity reports), and the continuous rise of civil litigation targeting firms. In this context, terminating an engagement without formalism exposes the firm to a double risk: disciplinary sanction before the regional disciplinary chamber of the Order, and a contractual liability action from the former client.

At Hayot Expertise, a firm registered with the French Order of Chartered Accountants of Paris Île-de-France, we support each year several directors facing a termination (either incurred or initiated). Recently, a fellow Paris firm asked us to take over an urgent patrimonial holding file: the previous termination, made by simple email, had left the annual tax return package unfinished six weeks before the filing deadline. This guide formalises the procedure we apply internally to avoid this kind of situation.

The chartered accountant is not an ordinary service provider: they exercise a regulated profession governed by Ordinance n° 45-2138 of 19 September 1945, supplemented by decree n° 2012-432 of 30 March 2012 on the conditions of practice and by the OEC Code of Conduct annexed to decree n° 2007-1387 of 27 September 2007.

Three principles shape the ability to terminate an engagement:

1. Independence and integrity (articles 145 et seq. of the Code of Conduct): if the engagement compromises the professional's independence, the termination becomes an obligation rather than a mere option.
2. Duty to advise and continuity: French civil case law (notably Cass. com., 16 May 2018, n° 17-11.668) confirms that the chartered accountant must warn the client in time to allow them to organise the handover.
3. Prompt return of the client file: the 2012 decree imposes the return of the documents belonging to the client as soon as the engagement ends, whether or not there is a fee dispute.

For a complete overview of the applicable professional framework, see our dedicated article on the obligations 2026 d'un expert-comptable à Paris as well as the catalogue des missions de l'expert-comptable.

The Code of Conduct does not provide an exhaustive list, but disciplinary practice and case law have identified six grounds that are regularly accepted.

Citable factual atom. Article L.561-2 of the French Monetary and Financial Code has included chartered accountants among the AML-obliged professions since ordinance n° 2009-104 of 30 January 2009 (transposition of the 3rd anti-money-laundering directive).

Specific case of non-payment#

Non-payment is the most frequently invoked ground. For it to support an ethically defensible termination, three cumulative conditions must be met: invoicing consistent with the engagement letter, prior formal notice sent by registered letter with deadline (15 to 30 days), and no serious challenge of the fees. Otherwise, a termination for non-payment may be reclassified as a wrongful termination.

Here is the procedure we systematically apply at Hayot Expertise when a termination becomes necessary.

1. Internal decision and qualification of the ground. The partner in charge of the file formalises in writing the chosen ground and obtains the sign-off of a second partner to avoid impulsive terminations.
2. Prior formal notice (non-payment, failure to produce documents). Reasonable deadline of 15 to 30 days, by LRAR, clearly stating the consequences in case of non-regularisation.
3. Notification of the termination by LRAR. Effective date, succinct and non-defamatory ground, reminder of the notice period and of the firm's return commitments.
4. Information to the regional Order when the termination occurs during a statutory engagement (contractual audit, assurance certificate, statutory audit mission). For a standard contractual engagement, informing the Order is not mandatory but remains recommended in tense situations.
5. Preparation of the handover file. Inventory of documents, trial balance as of the effective date, interim accounting situation, pending declarations and their deadlines, passwords and software access.
6. Physical or digital return of the file. Hand-over minutes signed by both parties, archiving of items proprietary to the firm (permanent file, working notes).
7. Final invoicing pro rata temporis under the engagement letter, without any termination penalty (unless an express and reasonable clause exists).
8. Administrative closure: deactivation of accesses, transmission to the successor firm if appointed, archiving in line with the statutory retention period (article 144 of the Code of Conduct: ten years).

The template below is designed for a contractual engagement covering bookkeeping and preparation of annual financial statements. It must be adapted to each situation (audit, statutory audit, ad-hoc advisory, court expertise). Copy-pasting without personalisation is a trap: case law sanctions terminations drafted in vague or stereotyped terms.

Termination for AML suspicion#

When a suspicion of money laundering or serious tax fraud emerges in the course of the engagement, the procedure is twofold. The firm must first file a suspicion declaration to Tracfin via the ERMES portal, without informing the client (tipping-off prohibition, article L.561-19 of the French Monetary and Financial Code). Only then can the termination be notified, using neutral terms: "persistent difficulties in carrying out the engagement" or "impossibility to maintain our professional independence". Any mention of the suspicion in the LRAR would constitute a criminal offence.

Termination of a statutory audit engagement#

The statutory auditor's mission is statutory and nominative for six financial years. Resignation is only admissible on serious grounds (article L.823-7 of the French Commercial Code): illness, conflict of interest, serious breach by the audited company that makes the mission impossible. It must be notified to the president of the competent court and to the Compagnie nationale des commissaires aux comptes (CNCC). A resignation without a legitimate ground exposes the auditor to disciplinary sanctions and to reimbursement of replacement costs.

Termination during an ongoing DGFiP tax audit#

If the client is under a tax audit at the time of termination, the firm must guarantee the continuity of the duty to advise until the end of the audit or organise a documented handover with the successor firm. A brutal termination in the middle of a procedure may be qualified as a serious breach of the duty to advise and trigger the firm's civil liability.

Termination during an assurance certificate or compilation engagement#

For these engagements with standardised value (NEP applied by transposition), the firm must ensure that the termination does not occur during the report-issuance phase, which must either be completed or expressly resumed by the successor firm.

• Underestimating the notice period. A fifteen-day notice close to a tax or social-security deadline is almost always reclassified as a wrongful termination.
• Invoking a general right of retention. The right of retention over original client documents is tightly framed; it is better to secure unpaid fees through a payment-injunction procedure.
• Notifying by simple email. Email does not provide a certified date and lacks the probative force of an LRAR.
• Mentioning the Tracfin suspicion in the LRAR. Absolute prohibition, criminal sanction.
• Omitting to return the parts of the permanent file that belong to the client. Common confusion between the firm's permanent working file (firm's property) and items provided by the client (to be returned).
• Forgetting to archive the file for ten years. The retention obligation runs from the date of termination, independently of any retention by the client.

Based on files processed in recent years, three grounds account on their own for nearly 70 % of terminations on the firm's initiative. First, non-payment for more than 90 days, particularly frequent at the end of a cash crunch among young structures. Second, client opacity around certain operations likely to fall within the AML scope: atypical flows with at-risk jurisdictions, refusal to provide supporting evidence on asset disposals, repeated inconsistencies between filings and banking flows. Lastly, loss of trust with governance: contact person changing every three months, contradictory instructions, pressing requests for adjustments outside the accounting framework.

Our conviction: the LRAR is never enough on its own to secure a termination. It must be combined with an evidence file that holds up in court (time-stamped unpaid invoices, exchanged emails, meeting minutes), a proposed successor firm where possible, and a documented handover of the client file. This level of formalism protects the firm during the ten years following the termination, the period during which civil liability can still be triggered.

To benchmark the fees applicable in an incoming engagement letter (and thus limit the risk of future non-payment), our simulateur de tarif expert-comptable and our fourchettes de tarifs expert-comptable 2026 give the orders of magnitude observed on the Paris market.

Hayot Expertise tip. Before any termination, organise a physical or video meeting with the client to formalise the breakdown of the relationship and try one last regularisation. In more than one file out of three, this meeting leads to an agreement (staggered payment of unpaid invoices, adjustment of the engagement scope, change of contact on the firm's side) that avoids termination. When it remains unavoidable, the meeting becomes additional evidence of your good faith and of your compliance with the duty to advise.

• Termination on the chartered accountant's initiative is governed by decree n° 2007-1387 (Code of Conduct) and decree n° 2012-432.
• Six grounds are regularly accepted: non-payment, conflict of interest, loss of independence, AML suspicion, refusal to cooperate, major disagreement.
• The LRAR with two-to-three-month notice is the rule for contractual engagements; an email alone is not enough.
• Prompt return of the client file; only the firm's permanent file remains with the firm.
• In case of AML suspicion, report to Tracfin before terminating, without mentioning the suspicion in the LRAR.
• The statutory audit mission follows a specific regime with notification to the court and to the CNCC.
• File retention runs ten years from the termination date (article 144 of the Code of Conduct).
