How to execute intellectual property assignment agreements

Secure your company's most valuable assets by legally transferring ownership of all created work from individuals to your business.

Get it in writing, right from the start

To protect your business, you must have every person who creates anything for it—including founders, employees, and contractors—sign an Intellectual Property (IP) Assignment Agreement. This is a formal legal document that transfers the ownership of creative and intellectual work (like code, designs, branding, or content) from the individual creator to your company. Without this, the person who made it could legally own it, even if you paid them, which could seriously damage your company's value and future prospects.

What is an IP Assignment Agreement?

Think of it like the deed to a house. An IP Assignment Agreement is the legal paperwork that proves your company owns the intellectual property it uses. Intellectual Property is the intangible assets that are often the most valuable part of a modern business. This includes:

  • Inventions and discoveries
  • Software code and databases
  • Brand names, logos, and slogans
  • Website content, articles, and marketing copy
  • Product designs and graphics

By default, the person who creates the work is the legal owner. An assignment agreement formally and permanently transfers that ownership to the business entity. This is not a handshake deal; it must be a signed, written contract.

Why is this so critical?

Overlooking this step can have severe consequences. Here’s why it’s one of the most important things you’ll do when setting up:

  • Secures Company Value: Your IP is a core asset. When you seek investment or want to sell your business, potential investors and buyers will perform 'due diligence' to check that your company undisputedly owns all its IP. Missing or poorly drafted agreements are a major red flag that can devalue your business or even kill a deal entirely.
  • Prevents Founder Disputes: It’s common for founders to build the initial product before the company is even formed. Each founder must assign the IP they created to the new company. This prevents a situation where a founder leaves and claims they personally own a critical piece of the technology or branding.
  • Provides Clarity with Contractors: Under UK law, a freelancer or contractor automatically owns the IP of the work they produce for you unless you have a written agreement that states otherwise. This is a vital protection when hiring outside help.
  • Avoids Legal Battles: Clear, upfront agreements prevent expensive and time-consuming disputes about who owns what later on.

How to put an IP Assignment Agreement in place

Follow these steps to ensure your IP is properly secured from day one.

  1. Use a solid legal template: Don't be tempted to copy and paste a generic agreement from the internet. The stakes are too high. Use a template from a reputable legal services provider or, ideally, have a solicitor draft one tailored to your business. This is a worthwhile investment.
  2. Identify who needs to sign: Make a list of everyone who has created or will create IP for the business. This includes all founders, all employees (even if their employment contract has an IP clause, a separate agreement can add stronger protection), and all contractors, freelancers, and agencies.
  3. Make it part of your onboarding: The best time to get the agreement signed is at the very beginning of the working relationship. Make it a standard part of your hiring and onboarding process for every single person. It is much harder to ask someone to sign it retrospectively, especially if they have already left the company.
  4. Ensure it's correctly signed and dated: The agreement must be signed by the individual creator and an authorised representative of your company (e.g., a director). Make sure it is dated correctly.
  5. Store it securely: Keep a digital copy of every signed agreement in a safe, organised folder. These are fundamental company records that you will need to access for any future funding rounds or sale of the business.

A final word of advice

When it comes to your company's intellectual property, if it isn't in writing, it doesn't count. Verbal agreements hold no water. Be diligent and methodical about getting these agreements signed from the very beginning. It’s a foundational step that protects the entire future of your business. If you are in any doubt, speak to a qualified legal professional.
