We are negotiating the purchase of part of our neighbour's garden in order to extend our own (ie not to build on).
What do we need to do for the sale to go ahead.
Do we need a surveyor to re-draw plans? What else do we need to do?
And how much is it all likely to cost (as this affects how much we can afford to pay for the land...)
Both sides are clueless really, so any advice gratefully received
