What is missing from the Wedding Ceremony?

I have never seen the signing of the Marriage License during the wedding ceremony. It is usually done in a hurried matter in a corner of the reception hall. This contract is the most important piece of the commitment that the two are making to each other. Why do we hide it like a dirty secret? Why is this piece of paper so umimportant in the wedding day yet it a major deal to erase when there is a divorce? Put this Wedding Contract right there in the middle of the marriage as a reminder that this for real and it is binding and should be handled with care and love.
