A China contract is generally effective when capable parties genuinely agree on lawful terms.
Under the Civil Code, a contract is typically formed when the parties reach agreement on the essential terms, unless a statute requires a particular form, government approval or registration. A signature or company chop is important evidence of authority and assent, but validity does not depend on a chop alone. Mandatory PRC rules, public-policy limits and transaction-specific licences can still override or delay effectiveness even when the paper looks complete.
5 questions before you choose the route.
This page identifies the right question and evidence. It does not determine the legal outcome on a reader’s facts.
Who are the parties?
Identify the legal entities, not trading names. Confirm each party exists and has capacity for this deal.
CapacityWas there genuine agreement?
Map offer, acceptance, essential terms and any condition that still has to occur.
AssentIs the subject-matter lawful?
Check negative-list, licensing, foreign-exchange and mandatory rules that can void or restrict the bargain.
LawfulnessIs extra form required?
Some deals need writing, notarisation, approval or registration before they take effect.
FormWho had authority to bind?
Legal representative, authorised signatory, chop custody and any board or shareholder approval.
AuthorityWorking rule: Map the regulated role before marketing or launch in China.
The signal ledger.
These facts move the question beyond a label and into a product, money-flow and control analysis.
Bring a compact evidence docket—not a pitch deck.
Give a compliance team or counsel the operating facts that reveal the perimeter.
Questions people ask before they build.
Short answers for orientation. The right result can change with the service model and current rules.
Does a missing company chop make the contract void?
Not automatically. A chop is strong evidence, but a valid signature by a person with authority, plus performance, can still bind the company. The reverse is also true: a stolen or unauthorised chop can be challenged.
Can an oral China contract be valid?
Yes for many commercial deals unless a statute requires writing. Proof is the practical problem. Written terms remain the safer route for cross-border work.
