Question: I have recently been served with a Notice to Treat on my lands. I am concerned about the level of tax I will pay. Can you set out any available reliefs? Answer: Notice to Treat gets served to all people involved in a CPO (compulsory purchase order). These are the people whose lands or properties are included in the CPO. They generally occur when a public infrastructure project needs to go ahead in a certain area (a motorway, for example).
