You can now Request a Signature from your colleagues and third party with the Request Signature button under the signature blocks. This allows you to notify signers only when their signatures is required.
Simply assign the signature blocs to a specific person or third party to be able later on to request their signature.
Note: Third parties and colleagues can still sign the contract, even if you have not requested their signature yet.
Note: First invite your third party to join your document via the Share button. When the signer has joined the contract and the document is finalized and agreed on, you can simply click Request Signature to notify your third party that his signature is requested.
Once you request a signature, the signer will receive a notification email requesting their signatures.
