Haven't looked at the docs yet but a thought just hit me.... (it does occur on occasion!)
What if they are planning on testifying that they were BOTH set up by the mystery third party? The one AL claims actually did the murder. Back to my earlier speculation about him being but a hired hand to "deliver the goods" to a third party, for a handsome fee. A crime right up his alley, no blood, no mess. And CL somehow helping in that - at some point.
AL might be claiming to the attorney that he was / they were both framed by Party C. I don't really think he's that stupid to bury the body at his place of employment. If he were...he'd have been locked up more and longer and never would have won $59,000 from the prison and the rest. Whoever buried that body there, assuming for a second it wasn't AL and he really did just kidnap her, might be the third party setting AL up for the murder.
Out there, I know, but I just peeked in and haven't seen exactly what is going on yet other than the two sets of attorneys conspiring together apparently. And this might explain both attorneys needing to formulate a joint case. Argh.
