I like the concept. However - and isn't there always an "however" - the main impediment is the insurance cost to do it. Those costs will need to be passed on to all clients whether they are impacted by flawed advice or not. Insurance isn't about what will happen but what could happen.
FP firms are already shedding low-value clients, despite not wanting to, due to compliance costs. FP may have helped lovely widow Mabel with Centerlink issues as she and her late husband had been with the firm for many years. No charge to Mabel as the cost was able to be absorbed in the past. Not now as all those actions and advice are required to be fully documented to comply with increased legislative requirements.
So lovely Mabel could be left swinging in the breeze with no one to help her with relatively simple issues from an FP who is switched on with Centerlink matters.
