Letter to New Employer of Former Employee_Non-Disclosure Template

In plain language: Opens the letter by identifying the sending company's legal name and contact, and addressing the new employer's authorized representative by name and title.

Common mistake: Addressing the letter to a generic department (e.g., 'Human Resources') rather than a named individual — reducing the likelihood it reaches a decision-maker and weakening its evidentiary value.

In plain language: A clear subject line and opening sentence that immediately state this is a notice regarding a former employee's continuing confidentiality obligations.

Common mistake: Writing a vague subject line like 'Important Notice' — recipients may deprioritize the letter, and the paper trail loses precision.

In plain language: Briefly describes the former employee's role and dates of employment at the sending company to establish context.

Common mistake: Including unnecessary performance details about the former employee. This letter is a legal notice, not a reference — irrelevant commentary can create defamation exposure.

In plain language: Identifies the specific non-disclosure agreement by name and date, and confirms it remains in full force and effect.

Common mistake: Citing the NDA without enclosing a copy. The new employer cannot act on — or acknowledge — an obligation they have not seen.

In plain language: Lists the general categories of confidential information the former employee agreed not to disclose, without revealing the specific confidential content itself.

Common mistake: Disclosing specific confidential details when describing what is protected — inadvertently leaking the very information the letter is meant to protect.

In plain language: Puts the new employer on notice that knowingly facilitating a breach of the NDA may expose them to legal liability, including tortious interference claims.

Common mistake: Omitting this clause entirely. Without it, the letter establishes notice but misses the opportunity to deter the new employer from encouraging disclosure.

In plain language: Asks the new employer to take reasonable steps to ensure the former employee does not disclose protected information in their new role, and requests written acknowledgment of receipt.

Common mistake: Setting no deadline for acknowledgment. An open-ended request produces no response and creates no follow-up trigger.

In plain language: Provides a named contact at the sending company for questions or correspondence, and closes the letter professionally.

Common mistake: Closing with a threatening tone rather than a cooperative one. Aggressive language reduces the chance of voluntary compliance and can escalate a manageable situation unnecessarily.

It is a formal business letter sent by a former employer to notify a departing employee's new workplace that the individual remains bound by a non-disclosure agreement. Its purpose is to put the new employer on constructive notice of existing confidentiality obligations so they cannot later claim ignorance, and to request cooperation in preventing any inadvertent or deliberate breach.

Companies send this letter when a former employee moves to a competitor or a company that handles similar sensitive information, and there is a reasonable concern that proprietary data — client lists, trade secrets, product plans, or pricing — could be disclosed. It creates a paper trail that strengthens the sender's position in any subsequent enforcement action and often deters the new employer from encouraging disclosure.

The letter itself is not a legally binding instrument — the underlying NDA is the binding contract. However, the letter creates a documented record that the new employer received notice of the obligation. This matters significantly if the sender later pursues a tortious interference claim, because it establishes that the new employer had constructive knowledge and cannot claim ignorance.

It is good practice to send the former employee a concurrent reminder of their continuing NDA obligations, either as a separate letter or by cc'ing them on this one. Doing so closes the loop on notice to both parties and reinforces that the former employer is actively monitoring compliance. Whether to cc or send separately depends on the sensitivity of the relationship and your legal counsel's guidance.

Do not include specific confidential details when describing what is protected — general category labels are sufficient. Avoid including performance evaluations, reasons for termination, or any characterization of the former employee's conduct that could form the basis of a defamation claim. Keep the letter factual, professional, and limited to the purpose of establishing notice of the NDA.

For most standard situations, a well-drafted template is sufficient and no formal legal review is required. However, if you have reason to believe a breach has already occurred, if the former employee was in a senior or highly sensitive role, or if you anticipate litigation, having legal counsel review and sign the letter before it goes out is advisable.

Send it as soon as you become aware of the new employment — ideally within the first two weeks of the former employee's start date at the new company. Early notice maximizes the deterrent effect and ensures the new employer has not yet encouraged or received any confidential disclosure. Delays reduce both the practical and legal value of the notice.

If no acknowledgment is received by the deadline you set, send a follow-up letter and document the attempt. If you have evidence of an actual or imminent breach, consult legal counsel about escalating to a formal cease-and-desist letter or seeking injunctive relief. The paper trail from this letter and any follow-up will support that escalation.
