Best method to make checks payable to two parties and 1099 Implications

All,

In R12, what is the best way to make checks payable to two parties?  For example, a legal payment needs to be paid to vendor and Law Office.  In 11i, the first line of the vendor address could be updated to

'AND XYZ Law Office'  so that check was payable to your vendor plus another party.  As long as the vendor Address lined up under the Pay To:  it worked fine.  I think R12 provides another option, but not sure what it is.  Also, is there any way to split out the payment between the two parties for 1099 purposes?
