All documents, including agreements, wills, and contracts are generally only valid when executed.  We often hear people saying "executed in full" which is almost stating the obvious a partially signed document is not executed and it can only be considered "executed" when all parts are signed and dated, so executed in full is kind of an overstatement.

Here is an excellent definition we found from obolloo.com:

An executed document is a legal document that has been signed by all parties involved. This can be a contract, deed, will, or any other type of agreement. In order to create an executed document, all parties must first agree and sign the document.

So long story short - executed = signed + dated in full.
