But back to the question - as Lippy might be aware - the UK standard for party walls/fences is that each property (where they adjoin) is allocated the wall/fence on one adjoining side only. So in a row of properties each house will legally own only one boundary wall/fence, apart from the house at the end which will have 2.
The individual ownership of each boundary is defined by which side the support posts are.
This is simplifying things because there will also be times when a property adjoins at the rear with yet another wall - like mine, (and god knows whose wall THAT is!) But these things are clearly set out in the property deeds.
As Pete says - erecting a fence/wall just within your boundary line is clearly your responsibility. But if the original developers construction is still there I would say you still have responsibility for it one way or another (and beware the neighbour taking it down and falsly 'extending' their property.)
You are right to be a little concerned IMO because these things can blow up into full scale neighbour battles. EG - one of my neighbours has planted a thick hedge and plans to remove the small boundary fence soon, which I'm not happy about because we will lose the defined boundary and his garden will merge with mine. But it's his fence - end of story. Depends on the neighbour of course.
Yes in the Uk very clear. I live in a terrace of housing and know exactley which wall I own. Makes things much simpler!
I think most people in Thailand would rightly or wrongly assume that all dividing walls between properties are shared. Where there is empty land either side of a property as in my case then to some degree we are free to build the wall higher. I guess the issue occurs when the new residents move in if they object to the height/ design of it.
Some of the extensions I have seen residents have errected wooden fences from inside supporting posts so its on their land and the original wall top width
remains untounched. For me this defeats the object as it still means people can walk on the top of the wall easily jumping into the garden.
Interesting point about the supporting posts. I have heard this mentioned a few times now that they establish ownership of the wall if their on your land.
Anyone else heard about this?
Anyway thanks for the posts some good advice and interesting topic. I guess the bottom line comes down to your neighbours and being amical and flexible. Hopefully I will have a few more years of blissfull peace!!
