Conveyancing solicitors negligence - failed to purchase all of the land

Mr and Mrs F purchased a new home with space to build a home office. Their solicitors failed to notice that the expansion land belonged to someone else and allowed them to purchase their home thinking they would own that land. Under a ‘no win, no fee’ agreement, Bell Lax recovered the cost of purchasing the land from Mr and Mrs F’s neighbours so that Mr and Mrs F could build their home office.
