you obliged to recieve, contest it even , you cant refuse it as such , you cabn only contest it ...... if there are blatent lies, from the "plaintif" , the person who his serving the writ , then , they are in breach......... i guess it is a high court writ , you are asking about, although a county court is just on a lower tier of the "high court " ranking .........
In general terms you do not have to accept the writ in the sense of physically taking hold of it but once you have identified yourself as being the person to whom the writ is addressed then there is little point in not accepting it. The consequences of being served with a writ are that you cannot at some later point say that you did not know about the proceedings.
The case could then proceed in your absence
