Does the signature work for legal documents?

While some of us on the team enjoy true crime podcasts, that doesn’t make use legal experts. You should check with your attorney or legal adviser about what’s acceptable and what’s not. We do have an article in our resource center that explains the differences between electronic signatures and digital signatures.
