The ESIGN Act and UETA make electronic signatures legally binding for most legal documents, giving e-signatures the same legal status as handwritten signatures. You can sign most engagement letters, contracts, and client agreements electronically, with exceptions for wills, certain court filings, and documents requiring notarization.
