Are electronic signatures legally binding under U.S. law?

Yes. Electronic signatures are generally enforceable under the ESIGN Act (15 U.S.C. ch. 96) and state UETA laws. Ensure intent to sign, consent to electronic records, ability to reproduce the record, and signer attribution to satisfy validity requirements.

Do I need notarization or witnesses for this contract?

Not typically. Ordinary contracts rarely require notarization or witnesses. Specific transactions or state filing requirements may require notarization or acknowledgements; Remote Online Notarization (RON) is available in many states but rules vary, so verify local notary law.

Who should sign on behalf of a company?

An authorized officer or agent should sign. Confirm authority through board resolutions, corporate bylaws, or power of attorney. For larger transactions, include a statement identifying the signer's title and representation to avoid later challenges to authority.

How can the agreement be amended after execution?

Amendments should be in writing and signed by authorized representatives of each party. Electronic signatures are acceptable if parties consent to electronic records and the platform captures an auditable record of the amendment.

What common pitfalls lead to disputes?

Common issues include vague scope or acceptance criteria, missing signatory authority, unclear IP assignment language, and inconsistent payment triggers. Address these explicitly and attach technical exhibits to reduce ambiguity.

How should executed copies be stored for compliance?

Store signed agreements in a secure contract repository with backups, access controls, and encryption. Follow retention rules such as IRS recordkeeping (IRC §6501(a)) and HIPAA retention where applicable (45 CFR §164.530(j)).
