Can a noncompete agreement be waived?

Some things that would be relevant to know are: what industry are you in? What specific competition are you worried about? Are you going to include non-disclosure provisions, no-solicitation provisions or non-circumvention provisions? What risks are you specifically worried about?

It depends on the terms of the non-compete and the size of your employer. Without seeing the agreement and knowing the size of your employer, I can't offer more advice.

If the future company buys the equity of your current employer, the Non-Compete continues in effect. If the future company buys the assets, the Non-Compete is terminated. I would request a sentence be added to the effect that "if there is a change of control of the Company (meaning more than 50% of the equity interest or 50% of the voting equity control) is sold or transferred, then this Non-Compete Agreement is terminated.

I am a WA State employment attorney. If you didn’t receive anything in return for signing the non-compete, it may be relatively easy to get out of it. If, however, you signed in return for something, such as a severance package, it will be challenging to get out of the agreement. However, many non-compete agreements are written overly broadly and may not be enforceable under the laws of WA and other states. You may want to consult with a WA State employment attorney for a review of the documents and law(s) of the state(s) where you may want to work or set up a business. (A WA State attorney can only provide legal advice in WA, but can help you find applicable law/case decisions for other states but without providing anything beyond information, much like a law librarian).

If you are in Washington State, where I'm licensed, as opposed to D.C., please let me know what kind of help you are looking for - have you already signed the agreement? I've been a WA State attorney for nearly 38 years, and specialize in employment law.
