If your startup plans to sign deals before the corporate entity is officially born, that’s exactly what you’re dealing with. Under U.S. law as of 2026, the corporation itself can’t be bound until it’s legally formed—so the founder who signed usually stays personally responsible unless the new company formally takes over the contract later.
Quick Fix Summary: A pre-incorporation contract isn’t binding on the future corporation until it’s formally adopted after the company exists. Founders should either delay signing until the corporate entity exists, or get explicit post-incorporation ratification; otherwise the promoter remains personally liable.

What’s Really Going On Here
When someone signs “for a company that doesn’t exist yet,” they’re technically signing as an individual. That’s because a corporation only becomes a legal person once the state issues its certificate of incorporation. At that exact moment of signing, the contract can’t be enforced against the corporation itself. The founder who put their name on the dotted line is usually on the hook—unless the newly formed corporation later accepts the agreement.
Here’s How to Handle This Properly
- Confirm the Company Doesn’t Exist Yet
- Before you sign anything, double-check the entity isn’t already registered in your state’s business database (like Florida’s or Delaware’s).
- Wait Until After Incorporation to Sign
- Incorporate first—file the Articles of Incorporation, pay the fees, get your EIN.
- Then sign the contract under the company’s name using the new corporate EIN.
- If You Have to Sign Early: Make Sure It Gets Adopted Later
- Once the certificate of incorporation arrives, hold a board meeting and pass a resolution adopting the pre-incorporation contract.
- Have the corporation issue a novation agreement—this releases the founder and substitutes the corporation as the party.
- File the resolution and novation in the corporate records (shareholder ledger, board minutes).
- Tell Everyone About the Risk Upfront
- Add a clause in the contract: “This agreement is expressly contingent on the corporation being formed and duly adopting this contract within 60 days of incorporation.”
When Things Go Wrong
- Try a Conditional Agreement Instead
- Insert “subject to formation of XYZ Corp by [date]” so the other party knows the contract isn’t binding unless the corporation is legally created and adopts it.
- Switch to an Early-Stage LLC or LLP
- An LLC or LLP can legally exist before formal corporate filing (state filing is enough). You can then sign the contract in the LLC’s name, avoiding promoter liability entirely.
- Protect Yourself With Insurance
- Grab directors-and-officers (D&O) insurance or errors-and-omissions (E&O) coverage for the pre-incorporation period.
How to Avoid This Situation Altogether
| Action | Deadline | Documentation |
|---|---|---|
| Reserve corporate name & file Articles of Incorporation | Day 0 | Certificate of Incorporation |
| Obtain EIN & open corporate bank account | Within 5 business days | IRS Form SS-4 confirmation & bank account opening letter |
| Hold first board meeting & adopt resolutions | Within 30 days of incorporation | Minutes signed by directors |
| Review all pre-incorporation letters of intent | Before signing any follow-on agreements | Amendment to contract or novation agreement |
Honestly, this is the kind of detail that trips up even experienced founders. State laws vary, and courts don’t always see eye to eye. Always run this by a qualified business attorney in the state where you’re incorporating—before you sign anything or adopt an existing contract. Promoter liability can stretch beyond the contract itself and drag in third-party claims you never saw coming.
