PASCES, the collection and enforcement agency for  support in Pennsylvania, has begun requiring that an obligor’s first support payment be paid at the time of the initial conference if an interim or a final order is entered.  This applies to child support, spousal support and APL cases. 

Montgomery County instituted this requirement a few months ago.  Chester County recently has done so.  I’m sure others will be following suit.  If you are an attorney representing an obligor, make sure your client does not find out about this "surprise" at the end of the conference.
