2 diff agreements?

My attorney sent me the separation agreements she has drafted. I was surprised that there were actually 2 documents rather than one document: 1)SETTLEMENT AGREEMENT/SEPARATION AGREEMENT REGARDING EQUITABLE DISTRIBUTION, ALIMONY, AND OTHER CONTRACTUAL AGREEMENTS ARISING OUT OF MARITAL RIGHTS, and 2) CONSENT ORDER FOR CHILD CUSTODY AND CHILD SUPPORT.

Is this typical? What is the advantage of doing it this way? Why is the custody agreement referred to as a Consent Order?

I normally outline custody in a consent order as it is easier to enforce and in order to change the provisions one party must show there has been a substantial change in circumstances. Further, the child support is enforceable by contempt, and eligible for wage withholding.
