Peter is the freeholder of flat, a lease over which Peter granted to Marie in 1994 for 50 years. Peter wishes to sell the freehold, but is concerned that there are a number of restrictive covenants which may influence the sale. Peter has heard the phrase "touch and concern the land", and seeks our advice with regards the following: Whether the following "touch and concern the land": i."no business to be carried out on these premises" ii."maintain the roof of the property" iii."cut the grass in the front garden"
