4 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.
Is a special written form required for this deal type?
Real estate, some guarantees and certain filings still expect paper or a chop.
FormWhat technology was used to sign?
Qualified e-signature, platform click-wrap, PDF scan, or a typed name in WeChat are different records.
MethodCan you prove who signed and that the file was not altered?
Certificate, audit log, hash and device control are the reliability file.
ReliabilityWill a bank or authority accept it?
Private-law validity is not the same as operational acceptance.
ChannelWorking rule: The Civil Code and the Electronic Signature Law do not deny legal effect solely because a document is electronic.
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.
Is a scanned chop on a PDF an electronic signature?
It is electronic data and may evidence execution, but it is not automatically a ‘reliable electronic signature’ under the statute. Treat it as a weaker record than a certified e-sign or a wet chop on the original.
Can WeChat form the contract?
Yes if the law does not require a special form and the thread shows agreement on essential terms. Preserve the full export; see the WeChat evidence Quick Answer.
