Just to give you all an update - Just got back from Calis and at the site AGM, I obtained formal agreement and subsequently got it written in the decision book that I could sign POA to the sites solicitor. The reason being is that the solicitor had told me that she couldn't act on my behalf without formal POA, for certain tasks eg: getting the bailiffs in for non paying maintenance.
So all sorted and formally done at the Notary.
