Hello, and welcome to Just Answer.
After researching this extensively, there seems to be no contact information on any Judge Mathis websites regarding how to request a copy of an episode; however, the episodes do seem to appear online about a week or two after they are broadcast, mainly on YouTube. I would recommend that you try to find this episode in about a week, by checking YouTube. Just for your reference, I believe the episode you're looking for, which was broadcast on Tuesday, 4/24/12, is episode #1774.
I did find one phone number to call, if you want to appear on the show (I know you don't want to appear on the show, but it's the only phone number I could find to make contact with the show's producers): 1-888-V-E-R-D-I-C-T.
You can try calling it and either leave a message, if you get an automated system, that you would like information on how to get a copy of the episode from Tuesday, 4/24/12, or hopefully, if you get a 'human' on the phone, ask the best way to accomplish this.
