Common questions

Is a drawn signature legally valid?

In many everyday situations, yes: most jurisdictions accept electronic signatures for routine documents. Nanodoc places your signature on the document but is not a certificate-based e-signing service, so for contracts that require identity verification and audit trails, use a dedicated e-signature platform.

Can other people fill out the forms I create?

Yes. Fillable fields you add are saved as standard PDF form fields, so recipients can complete them in common PDF readers.

Do I need an account to sign a document?

No. There is no sign-up and no login. Open the editor and sign.
