Hi Leah. the signature of JP does not add any weight to statements. As long as the person making statement signs off on it, that is all that matters. You can witness statements. Anyone over 18 can. As Agent Shadow says, there would be circs where a JP autograph is required, but for the run of the mill personal injury cases, in Qld, I doubt that would be necessary. I have never had a query over signed statements in about 2200 cases out of 2200.
