Hello I am a solicitor with over 15 years experience. I will try to help you with this.
Does he say why he thinks the land is his?
He wrote in his letter to us that when he purchased his plot he came to an agreement with the builder to purchase an extra four feet of width to the plot to facilitate minor alterations to construct a passage entrance and a two feet clearance on the east side of his garage to the boundary line for maintenance.
Why do you say the boundary is where you think it is? Do you have the title plans?
The fence was put in the same position the old one was apart from adding extra fence in front of the garage which he is saying has 2 feet of land is his our deeds only have a line drawing with no measurements and they say house frontage of 48 feet or thereabouts
Do you know how long a fence has been following that line in total?
The fence that is there now has been 16 years and the one we replaced was rotten being held up by support posts so probably more than 25 to 30 years
