Section 425. Agreement to support

If an agreement for the support of the
  petitioner is brought about, it must be reduced to writing and submitted
  to the family court  or  a  support  magistrate  appointed  pursuant  to
  section  four hundred thirty-nine of this act for approval. If the court
  or support magistrate approves it, the court without further hearing may
  thereupon enter an order for  the  support  of  the  petitioner  by  the
  respondent in accordance with the agreement, which shall be binding upon
  the respondent and shall in all respects be a valid order as though made
  after  process  had been issued out of the court. The court record shall
  show that such order was made upon agreement.
