If a principal signer is physically unable to sign, what does Illinois law allow them to do?

Illinois law allows a principal signer who is physically unable to sign to direct another person to sign on their behalf. This provision is in place to ensure that individuals who might have physical disabilities or limitations still have the ability to execute documents legally. When a principal cannot physically sign, having an authorized individual act on their behalf maintains the integrity of the signing process and allows for the legal formalities to be upheld under the law.

While other options may seem feasible in some contexts, they do not align with the specific legal allowances provided under Illinois law. For instance, signing with a thumbprint may not meet the requirement for a valid signature unless specific conditions are met, and digital signatures might not be acceptable in every situation. Providing a signature through video calls does not formalize the signing process as intended in legal contexts. Therefore, directing someone else to sign remains the appropriate and legally sanctioned method for situations where the principal signer is unable to do so personally.
