When a Contract Isn’t Worth the Paper It’s On: Key Mistakes That Void Agreements in California

Steven McLellan & Claire Melehani

Void Agreements in California

Not every signed contract is enforceable—and relying on a defective agreement can be a costly mistake.

California contract law is unforgiving when key elements are missing or improperly drafted.


Common Contract Defects


Contracts may be invalid due to:

  • Lack of mutual assent
  • Unlawful or unconscionable terms
  • Failure of consideration
  • Statutory violations specific to California

Even small drafting errors can have major consequences.


Why “Templates” Often Fail


Generic or AI-generated contracts often:

  • Ignore California-specific requirements
  • Conflict with public policy
  • Fail under real-world disputes


Courts do not fix bad contracts—they enforce or void them.


What Happens When a Contract Fails

A defective contract can lead to:

  • Loss of expected revenue
  • Inability to enforce rights
  • Exposure to counterclaims


Litigation then shifts from enforcement to damage control.
