An electronic contract: legal force, e-signature, and evidence
What proves that a file was signed and was not changed if there is a dispute
What to check in an electronic contract before you enter it
In an electronic contract the dispute is more often about the signature than the text: who signed the file, when, and whether it changed after signing.

What an electronic contract is
An electronic contract is a contract made in electronic form, with an electronic signature or without one (depending on what the law requires).
Under the Civil Code of the Russian Federation, a contract may be made in any form provided for transactions, unless the law sets a specific form. An electronic contract has the same legal force as a paper one if certain conditions are met.
Types of electronic contracts
1. A contract with an electronic signature
A contract signed with a qualified electronic signature (QES) has the same legal force as a contract on paper. A QES confirms:
- The identity of the signer
- That the document was not changed after signing
- The legal significance of the document
2. A contract without an electronic signature
Some contracts can be made in electronic form without an electronic signature if the law or the parties’ agreement says so expressly. For example:
- A public offer (for example, terms of use on a website)
- Contracts where acceptance is expressed by an act (for example, paying for goods)
- Contracts between individuals for small amounts
Electronic signatures: types and specifics
Simple electronic signature (SES)
A simple electronic signature is a code, password, or other means that confirms an electronic signature was formed by a particular person. An SES has legal force if:
- The law says so expressly
- The parties have agreed to it
- It is used inside an information system that meets the requirements
Limits:
An SES cannot be used to sign documents that require notarization or state registration.
Qualified electronic signature (QES)
A qualified electronic signature is an electronic signature that:
- Is created using cryptographic information-protection tools
- Meets the requirements of the Federal Law on Electronic Signatures
- Uses a signature-verification key stated in a qualified certificate
A QES has the same legal force as a handwritten signature on a paper document. It can be used for any contract except those that require notarization.
What to keep as proof of signing
If the contract is signed online, collect a set of evidence in advance. In a dispute, that set is what confirms the transaction is valid.
- The original contract file with the signature and a time stamp
- A certificate-verification report as of the signing date
- EDO platform logs: who signed, from which account, and when
- Proof of the signer’s authority (power of attorney, order, constitutional documents)
- An export of the document card from the EDO system, with the status history
How to store it:
Keep the evidence in two independent places: in the EDO system and in the company’s internal archive. That lowers the risk of losing data if you change provider.
Advantages of electronic contracts
Advantages:
- Speed: A contract can be made in minutes, without waiting for a meeting
- Convenience: No need to print, sign, and scan documents
- Savings: Savings on paper, printing, and delivery

Risks of electronic contracts
1. Technical risks
- Loss of data if the system fails
- A system breach and a forged signature
- Problems accessing the document
- Incompatible formats
2. Legal risks
- The contract is invalid if it was executed incorrectly
- Difficulty proving the case in court
- Problems identifying the parties
- No original of the document
3. How to reduce the risks
Recommendations:
- Use a qualified electronic signature for important contracts
- Keep copies of contracts in a reliable place
- Use proven platforms for electronic document exchange
- Check that the electronic-signature certificate is valid
- Keep a log of every contract you sign
- Make backups regularly
What is specific about checking electronic contracts
When you check electronic contracts, pay attention to:
- Validity of the electronic signature: Check that the signature is valid and has not been revoked
- Identification of the parties: Make sure the contract was signed by the right people
- That the document is unchanged: Check that the document was not altered after signing
- Document format: Make sure the document can be opened and read
- Content: Check every term of the contract the same way you would on paper
When you cannot use an electronic contract
Limits:
- Contracts that require notarization (for example, a contract for the sale of real estate)
- Contracts that require state registration
- Contracts pledging real estate
- Annuity contracts (dogovor renty)
- Contracts where the law expressly prohibits electronic form
What to keep after signing
For a dispute you need the file itself, the EDO operator’s receipt, and the time mark of the signature. A signature does not fix bad terms: check the penalty, withdrawal, and the subject in the text the same way you would in a paper contract.
- The contract file in the form that was signed, not “the latest version from email”
- The operator’s receipt or a signing protocol with the date and an identifier
- A power of attorney or a machine-readable power of attorney (MChD), if the signer was not the director
If you need a general checklist for the substance of the terms (not only the e-signature), use a separate piece: how to check a contract before signing.
