English to Japanese Law/Patents Law: Contract(s) this frase was in the consent.

Whole sentence goes like this."In consideration of one pound, the receipt, sufficiency and adequacy of which you acknowledge:"
I saw this sentence the pair of English and Spanish though… It is an English cinsent for perticipating a program. I thought there is a particular way to say explessing rather than direct meaning. It was the first line of consent after greeting and before real terms. If you know it please let me know as soon as possible.

Thank youvery much.
