First - hello

Second - my question.
I've been out of music for a goodly while - becoming a lawyer in the interim - and have only returned to it in the last year or so; the business side is now starting to become relevant.
Worked on a collab (outside Taxi) with some reasonably well-known guys agreed splits, uploaded stems. Silence.
My musical background and experience of various folk in the industry tells me that I shouldn't be overly bothered about this - at my level of things this isn't exactly a business renowned for its mastery of paperwork.
On the other hand, my legal background has me twitching at the fact that nearly a month has passed (I have chased once) and I've yet to see paperwork.
It could be that the deal has died (in which case a call would be nice but no matter), or it could just be that these are typical timescales.
It occurred to me that this might be a good place to ask not only about this instance but in general terms too.
All advice appreciated, thanks
