How do I pay a non-employee spouse?

I have an employee that retired and is receiving pension restoration plan payments on a monthly basis.  I understand that we are going to receive a QDRO to pay the ex-spouse a specified amount each month as well.  The way I pay the retired employee right now is to add a paysheet each month and input the amount I want to pay him and deduct the taxes accordingly. How do I set up the ex-spouse to pay in PeopleSoft?  I have never paid anyone who is or never has been an employee.

Thanks
