I may need to claim UC at somepoint.
At the moment I have nothing official about how and what my Ex should pay me each month. He just sends a bank transfer. There's no court orders, no CM agency.
However, for easy numbers, lets say he sends me £1000 a month, to prove a point for this question.
If I say the £1000 is child maintenance, (and if I'm eligible for UC) then the £1000 won't be deducted from it. But if I said £500 was CM (if based on the CM calculator) and the other £500 was voluntary topups/incidentals/SM/whatever, then that £500 perhaps would get deducted from any UC applicable.
So when people do get assessed for UC, do they just say all money from their Ex is CM, to avoid anything being deducted from UC entitlement? Or does the UC assessment check what amount of the money coming from the Ex, should be considered as CM, and not (deductable) SM. Ie, do they contact him, ask him his salary, and work out themselves what portion of the £1000 should be considered as CM and what should be considered as SM.
