How to Disclose a Side Project to Your Employer in English

Learn the English phrases for telling your employer about a side project, addressing IP ownership concerns, and requesting written approval.

Many employment contracts include broad intellectual property assignment clauses that could, in theory, claim ownership of anything you build — even unrelated side projects done on your own time. This guide gives you the English for disclosing a side project proactively, addressing ownership concerns, and getting clear approval in writing.


Raising the Disclosure

Bring it up directly rather than hoping it goes unnoticed.

  • “I wanted to let you know I’ve been working on a personal project outside of work hours, and I’d like to make sure it’s not a conflict of interest.”
  • “I’m building something unrelated to our product on my own time, and I want to be transparent about it before it goes any further.”
  • “Is there a process for disclosing outside projects, or should I just document this in an email to you and HR?”

Describing the Project Clearly

Be specific enough that there’s no ambiguity about overlap with your employer’s business.

  • “It’s a [brief description] — it doesn’t compete with anything we do here, and it doesn’t use any of our proprietary tools or codebase.”
  • “I’m not using company time, equipment, or any confidential information for this — it’s entirely separate infrastructure and hours.”
  • “The project is in a different domain than our product, but I wanted to flag it anyway out of caution.”

Addressing IP Ownership Directly

Ask the question explicitly rather than assuming the contract doesn’t apply.

  • “Given the IP assignment clause in my contract, I want to confirm this falls outside what the company could claim ownership of.”
  • “Could we get written confirmation that this project, built entirely outside work hours and without company resources, isn’t considered company IP?”
  • “I’d like this documented so there’s no ambiguity later if the project ever grows into something more.”

Requesting Written Approval

Don’t rely on a verbal “that’s fine” for something with legal implications.

  • “Could you send a short email confirming this was disclosed and approved, just so we both have a record?”
  • “I’d feel more comfortable if HR could put this in writing rather than leaving it as a verbal understanding.”
  • “If there’s a formal outside-activity disclosure form, I’m happy to fill it out instead of just emailing you directly.”

Handling Pushback or a Conflict Determination

If your employer raises a concern, engage constructively rather than defensively.

  • “I understand the concern — can you help me understand specifically what part of this overlaps with our business?”
  • “Would adjusting the scope of the project resolve the conflict, or is this an area you’d need me to avoid entirely?”
  • “I want to find a resolution here rather than just quietly proceeding without agreement.”
