This answer was rated:

I have a client who is moving on to using new technology, and has requested the source code provided by my company for several applications. I have never been asked for the source code, and do not currently have a legal contract with this client. What are my options? If I release the code, how do I protect myself from future responsibility for these applications and is there usually a fee that a client is to pay for the source code? We have been paid for our time to develop the applications, so this is not an issue. A new company will be taking on the future work, and we will not be part of the development. I must provide a letter to release the code, but I also want to ensure we can use the code ourselves in the future as well. Please advise asap.


I hope this message finds you well. To directly address the issue, the source code is indeed intellectual property of you and your company and you should require a fee for its use. Decide what an appropriate fee would be based on the market and work to develope this intellectual property and ask this fee for use.


The handling of this arrangement should be done in a small contract that does a few things:


  1. It should address the source code as directly as possible in its identification
  2. It should of course address the parties to the contract
  3. It should address the financial aspects, i.e., money paid for use of the source code.
  4. It should prevent the purchaser from using the code outside of their own work.
  5. It should release you, as you stated, from any and all legal liability that shall result from the purchaser's use of the code.
  6. It should specify that you are still able to use the code as you may need without any incumberences.
  7. It should specify that the company destroy the code at the end of their use.

The contract does not have to be big, just needs to address the essential aspects as detailed above.


I hope this helps and best wishes.

Just to confirm - I am within my full rights to request a fee for the source code even though we have been paid for our time to develop the applications over the last couple of years. (I felt this was the case, however my client feels differently. They already broke a letter of agreement with me last year, so I have been cautious regarding our property and relationship with them ever since then.)


You absolutely have the right to charge for the source code unless the specs and initial contract specified otherwise. Moreover, the company should expect to be charged for the use of the source code. Intellectual property is high dollar stuff, especially in your area of expertise and you should protect it with diligence and be compensated accordingly.

Much appreciated. Before I accept, any chance you (or someone you can direct me to asap) might draft a letter for me for an additional charge? It would save me time which I would appreciate. I would fill in the blanks re. the intellectual property fee once I figure out what that should be based on the market

Here is a template. You should sign and date as well as the individuals and have it notarized.
