Electronic signatures have changed how companies and people handle legal agreements and transactions in this digital age. Gone are the days when contracts had to be written out, signed, and sent by mail or fax to be approved. Agreements can be signed quickly from anywhere with an electronic signature, which speeds up the process and is better for the environment.
Using digital signature software, typing a name, or clicking an “I agree” button are all ways that people and businesses can sign papers electronically. This is also known as e-signatures. Many fields, like real estate, banking, healthcare, and legal services, use these signatures to make things run more smoothly and reduce paperwork.
Why Understanding Their Legality in California is Important
Even though electronic signatures have many benefits, knowing the law about them is important. This is especially true in California, where businesses and people must follow state and federal rules about how they can be used. If you don’t understand or follow these rules correctly, it could cause disagreements, contracts that can’t be enforced, or even legal penalties.
California follows the federal Electronic Signatures in Global and National Commerce (ESIGN) Act and the state-specific Uniform Electronic Transactions Act (UETA) to ensure electronic signatures are legally valid. However, not all documents can be signed electronically, and some require additional security measures for authenticity and compliance.
Businesses and individuals can confidently utilize electronic signatures by understanding the legal context and ensuring their transactions are valid, secure, and enforceable under California law.
Legal Framework
Federal and state legislation accept California electronic signatures. These rules give e-signatures the same legal power as handwritten signatures, making electronic transactions easier for businesses and people. The federal Electronic Signatures in Global and National Commerce (ESIGN) Act (2000) and the state Uniform Electronic Transactions Act (UETA) (1999) govern electronic signatures in California
Federal Law – ESIGN Act (2000)
The Electronic Signatures in Global and National Commerce Act (ESIGN Act) was enacted in 2000 to promote the use of electronic signatures in interstate and foreign commerce. This law ensures that electronic signatures and contracts cannot be denied legal effect or enforceability simply because they are in digital form.
Key Provisions of the ESIGN Act:
- Equal Legal Standing – An electronic signature is as legally valid as a handwritten one. A contract or record cannot be rejected solely because it is electronic.
- Consumer Consent Requirement – If electronic records are used in consumer transactions, the consumer must provide consent and be informed of their rights to receive paper copies.
- Record Retention – Electronic records must be kept accurate, accessible, and repeatable for future reference.
- Applicability – The ESIGN Act applies to most industries, including finance, insurance, healthcare, and business transactions. However, some documents (such as wills and court orders) are exempt.
The ESIGN Act provides a broad legal foundation for using electronic signatures across the United States, including California, as long as all parties consent to the electronic transaction.
California State Law – UETA (1999)
Before the federal ESIGN Act was passed, California adopted the Uniform Electronic Transactions Act (UETA) in 1999, making it one of the first states to establish legal guidelines for electronic signatures at the state level. The UETA is codified under California Civil Code Sections 1633.1 – 1633.17 and provides a legal framework for electronic transactions specifically within California.
Key Provisions of UETA in California:
- Legal Recognition of Electronic Signatures – If all parties agree to conduct business electronically, an electronic signature has the same legal standing as a handwritten signature.
- Scope of Application – UETA applies to transactions between individuals, businesses, and government entities but does not cover certain legal documents such as wills, family law matters, and court orders.
- Consent Requirement – Similar to the ESIGN Act, UETA requires parties to consent to using electronic signatures and transactions.
- Secure Recordkeeping – Electronic records must be maintained to preserve accuracy, integrity, and accessibility.
Since both the ESIGN Act and UETA apply in California, UETA governs transactions at the state level, while the ESIGN Act governs transactions that involve interstate or international commerce.
How the ESIGN Act and UETA Work Together in California
- For transactions within California: The UETA is the governing law. However, the federal law takes precedence if there is a conflict with the ESIGN Act.
- For transactions across state lines or internationally: The ESIGN Act applies to ensure electronic contracts and signatures are valid nationwide.
- For consumer transactions: Businesses must comply with additional requirements, such as obtaining clear consent and providing the option for paper records.
Businesses and people in California can use electronic signatures with confidence if they know these laws and make sure they follow federal and state rules.
Requirements for Valid Electronic Signatures
The ESIGN Act (2000) and the California UETA (1999) spell out specific rules that an electronic signature must meet to bind in California legally. These rules make sure that electronic signatures are real, safe, and enforceable. Here are the main things that determine if an electronic signature is valid.
1. Intent to Sign
For any electronic sign or handwritten to be legally valid, the individual signing the document must have a clear and intentional willingness to sign. This means:
The signer must knowingly provide their electronic signature.
The signature cannot be coerced, forged, or unintentionally generated.
The electronic system must provide a clear option to sign or decline the agreement.
Example: If an employee is signing an NDA (Non-Disclosure Agreement) electronically, they must be explicitly aware that clicking “Sign” or typing their name represents their legal agreement to the contract.
2. Consent to Electronic Transactions
Before an electronic signature is legally binding, all parties must consent to conducting business electronically. Consent is especially important in transactions involving consumers, as companies must inform users about their rights and provide alternatives if they prefer paper documentation.
Consent can be obtained explicitly (e.g., by clicking a checkbox that states “I agree to sign electronically”).
In some cases, businesses must also provide disclosure statements explaining how electronic records will be used and stored.
The option to withdraw consent should be available in applicable cases, especially in consumer transactions.
Example: When signing an online mortgage agreement, the lender must inform the borrower that they consent to electronic signatures instead of physical ones.
3. Association with the Record
It doesn’t matter if the signature is electronic or written by hand; the person signing the paper must clearly and knowingly want to sign it. In other words, the person signing must knowingly use a computer signature.
The electronic system must record essential details such as:
Who signed the document (signer’s name, email, or digital ID).
When the document was signed (timestamp of signing).
What document was signed (ensuring the signature is embedded within the specific agreement)?
Digital signature technologies often use cryptographic hashes to link signatures and documents securely.
Example: If a company uses DocuSign to collect e-signatures, the system ensures that each signature is tied to a specific contract and cannot be transferred to another document.
4. Record Retention
To maintain the validity of an electronic signature, the signed document must be securely stored and remain accessible for future reference. Both the ESIGN Act and UETA require that electronic records be retained in a way that ensures:
Accuracy: The document must remain unchanged and unaltered.
Accessibility: The document should be easily retrievable by authorized parties.
Integrity: Security measures (such as encryption or blockchain verification) should be in place to prevent tampering or unauthorized modifications.
Example: A company that signs an employment contract electronically must ensure the document is stored securely in a cloud-based system or an internal database where it can be accessed by both the employer and employee if needed.
Exceptions – When Electronic Signatures Are Not Accepted
While electronic signatures are legally valid in most cases under the ESIGN Act (2000) and UETA (1999), certain documents and transactions are excluded from electronic signing due to legal, security, or procedural concerns. These exceptions ensure critical agreements’ integrity, authenticity, and legality.
1. Wills, Trusts, and Family Law Documents
Documents related to estate planning and family law often require handwritten signatures to ensure authenticity and avoid disputes.
Wills & Codicils: California will typically require wet (handwritten) signatures and witnesses to be legally valid. This prevents fraud or undue influence on the testator (the person making the will).
Trust Documents: While some trusts may allow electronic signatures, many require notarized, physical signatures for legal enforceability.
Prenuptial & Postnuptial Agreements: These agreements often require notarized, physical signatures to be legally binding and recognized in court.
Example: If a person wants to create a will and leave assets to their family, they must physically sign the document before witnesses. An electronic signature would not be legally valid.
2. Court Orders and Some Legal Documents
Due to strict verification procedures, certain legal documents, court filings, and orders require physical signatures to prevent forgery or tampering.
Court Orders & Filings: While some courts accept e-signatures for specific filings, many require wet signatures for judgments, warrants, and official court orders.
Divorce and Adoption Papers: These documents require additional legal scrutiny and notarization, making electronic signatures invalid in most cases.
Power of Attorney (POA): Although California sometimes allows electronic notarization, POA documents often require physical notarization to be legally binding.
Example: If a judge signs an official restraining order, it must have a physical signature to be considered enforceable by law enforcement.
3. Certain Real Estate Transactions
Although many real estate transactions accept electronic signatures, some property-related documents in California still require physical signatures and notarization.
Deeds & Property Transfers: A wet signature is typically required to record a deed with the county recorder’s office.
Foreclosure & Eviction Notices: Some legal notices related to property rights must be signed physically to ensure compliance with tenant protection laws.
Mortgage & Loan Agreements: While many lenders accept e-signatures, some loan modifications and notarized mortgage documents still require physical signatures.
Example: If a homeowner wants to transfer property ownership to another person, they must sign the deed physically and have it notarized before it can be recorded.
Final Thoughts on Exceptions
Although electronic signatures are widely accepted in California, certain legal documents require traditional handwritten signatures for additional security and verification. Before signing an important document electronically, verifying whether an e-signature is legally acceptable or if a physical signature is required is essential.
Digital Signatures vs. Electronic Signatures
Many people use electronic and digital signatures interchangeably, but they are different. While both are used for signing documents electronically, digital signatures offer higher security and authentication than basic electronic signatures.
1. What Is an Electronic Signature?
An electronic signature (e-signature) is any mark, symbol, or process used to indicate consent or approval on an electronic document. It can be as simple as:
Typing your name in a signature field.
Clicking an “I Agree” checkbox.
Using a stylus or touchscreen to sign a document.
Uploading an image of a handwritten signature.
Example: When you sign a contract using DocuSign or click “I accept” on an online agreement, you use an electronic signature.
Pros of Electronic Signatures:
-Easy to use and widely accepted.
-Fast and convenient for online transactions.
-Legally binding under UETA and the ESIGN Act.
Cons of Electronic Signatures:
-Less secure than digital signatures.
-Can be forged or tampered with more easily.
2. What Is a Digital Signature?
A digital signature is an electronic signature that uses encryption and cryptographic technology to ensure the signature is authentic, secure, and tamper-proof. Digital signatures are created using:
Public Key Infrastructure (PKI): A system that generates unique digital certificates for verification.
Encryption: A mathematical process that locks the signature to the document and prevents tampering.
Audit Trails: A record of who signed, when, and where they signed.
Example: When signing a document using Adobe Sign with a verified digital certificate, the system applies an encrypted digital signature that cannot be altered.
Pros of Digital Signatures:
-More secure than basic electronic signatures.
-Cannot be forged or altered.
-Includes verification methods like timestamps and unique digital certificates.
Cons of Digital Signatures:
-More complex and costly to implement.
-Requires special software and verification processes.

- By understanding the differences, businesses and individuals can choose the right type of electronic signature to ensure legal compliance and security in their transactions.
Best Practices for Using Electronic Signatures in California
To ensure electronic signatures are legally valid and secure in California, businesses and individuals must follow best practices. These guidelines help protect against fraud, ensure compliance with state and federal laws, and maintain the integrity of signed documents.
1. Verify Signer Identity
Verifying the identity of the person signing a document is crucial to prevent fraud and unauthorized transactions. In California, businesses and organizations can use several methods for identity verification:
Multi-Factor Authentication (MFA): Requiring users to verify their identity through SMS codes, email confirmations, or biometric authentication (e.g., fingerprint or facial recognition).
Government-Issued ID Verification: Some electronic signature platforms allow users to upload a driver’s license or passport for verification.
IP Address & Geolocation Tracking: Many e-signature services log the signer’s IP address and location for added security.
Audit Trails: Electronic signature platforms generate a detailed log of who signed the document when they signed it, and what device they used.
Example: A financial institution requiring a customer to enter a one-time password (OTP) sent to their phone before signing a digital loan agreement.
2. Maintain Proper Records
Electronic signatures must be securely stored and easily retrievable in case of future disputes or audits. Proper recordkeeping ensures legal compliance and protects businesses from potential fraud claims.
Store signed documents securely: Use encrypted cloud storage or a secure document management system to prevent unauthorized access.
Ensure documents are tamper-proof: A legally valid e-signature system should lock documents after signing to prevent modifications.
Keep records for the required retention period: Depending on the type of agreement, California law may require keeping documents for several years for legal and tax purposes.
Enable easy access to records: Ensure signed agreements can be retrieved quickly for audits, disputes, or legal proceedings.
Example: A company using Adobe Sign or DocuSign to keep a digital record of all employment contracts for at least seven years, ensuring compliance with labour laws.
3. Use Legally Compliant Platforms
Not all electronic signature platforms meet the legal requirements of the ESIGN Act and California’s UETA. It is essential to choose a reliable and legally compliant e-signature solution.
Use platforms that provide audit trails and encryption: Secure platforms encrypt documents and maintain an unalterable record of the signing process.
Ensure compliance with industry regulations:
HIPAA-compliant e-signatures for healthcare documents.
FINRA & SEC-compliant e-signatures for financial agreements.
GDPR-compliant e-signatures for international transactions.
Check for third-party certifications: Trusted platforms often have ISO 27001, SOC 2, or eIDAS certifications for extra security.
Example: A healthcare provider using HelloSign (HIPAA-compliant) to collect patient consent forms digitally while ensuring legal protection and compliance.
Conclusion
Electronic signatures are legally valid and widely accepted in California, making them a convenient and efficient way to conduct business transactions. However, to ensure legal compliance and security, businesses and individuals must follow best practices such as:
-Verifying signer identity through secure authentication methods.
-Maintaining proper records by securely storing signed documents.
-Using legally compliant e-signature platforms that meet industry standards.
By implementing these best practices, businesses can streamline operations while ensuring electronic agreements’ security, compliance, and legal enforceability. Whether signing a contract, an NDA, or an employment agreement, following these steps will help protect your interests and maintain trust in digital transactions.
