A more thorough explanation:

The execution clause is a section of a legal document, such as a deed, that includes important information about the signing and sealing of the document. This section typically includes the date of the signing, the seal (if required), and the signatures of the grantor, grantor's spouse, and witnesses.

For example, a typical execution clause in a deed might look like this:

IN WITNESS WHEREOF, the Grantor has executed this Deed on the day and year first above written.

SIGNED, SEALED, AND DELIVERED IN THE PRESENCE OF:

_____________________________ (SEAL)

Grantor's Signature

_____________________________

Grantor's Spouse's Signature

_____________________________

Witness Signature

_____________________________

Witness Signature

This execution clause includes the date of the signing, the seal (represented by the blank line with the word "SEAL" next to it), and the signatures of the grantor, grantor's spouse, and two witnesses. These signatures indicate that the document has been properly executed and is legally binding.
