What 'fully executed' means
A contract is fully executed when every party has signed. Until then, one side has signed and the other hasn't — which can leave things uncertain. Countersign promptly and send the final copy to everyone so all parties have the same version.
Check the document hasn't been changed since you last saw it before you countersign.
