why only part of the page gets sent to me

I use the form for my family services agreement, its a pretty long document of what the company does and what the family is required to do, but when they fill it out and it gets sent to me, its not the whole form, its only  the bottom where they fill in sign and date and put address, so I can never prove in a court of law that they signed the agreement, I cant get the whole form they sign. how do I get the whole form and not just the signatures?

I have attached what gets sent to me, and if you look at the service agreement all the wording is gone. please help. thank you 503.619.5565 Julie
