Should I tell new neighbours their trees are inside my fence?

[miaCara]

Several years ago my next door neighbour had her idiot son put up a much needed replacement fence between our gardens. However , instead of following the line of the old fence he opted for the easier method of simply going round any obstacles.
In this case the obstacles are 3 quite mature trees which the original owner of the house had planted/allowed to grow along the fence line.
The trees are now on my side of the fence and although sturdy enough they wouldnt be my choice of tree .
There are now new owners of the property who are not yet aware of the tree/fence situation.
So should I tell them of their tree ownership? They are a young family and probably couldnt be less interested in trees just now.
What happens if there is a problem with the trees - is this down to my insurance since its within the new fence line for example?

“Hey, not sure if your solicitors flagged this or not, but when the previous owner erected this fence, they chose to place it X inches inside the boundary. So X inches of your property is in the other side of this fence. If you ever want to replace the fence or do anything with these trees, just let me know. The original boundary markers are still in place, and if you’d ever like to see them, just let me know.”

No solicitor would flag it up as it’s a non issue

@rwalker Agreed. It’s not even a survey issue!

The solicitor couldn’t flag it up as they wouldn’t see the actual land (to notice that the fence doesn’t follow the original boundary line).
Usually all they would see is the land registry title plan, and they’d ask the buyer to confirm that the land they’re buying matches the title plan.
Only a boundary surveyor (doing an actual boundary survey, not a general house survey) can confirm the real exact boundary, and they’d usually need to do a site visit and look at historical documents etc in order to do that.
As I said upthread, land registry title plans don’t claim to give the exact accurate boundary, they’re usually only accurate to within a meter or so.

Depends if you're bothered about trimming or removing the trees. To pretend they are yours means the neighbours won't do anything to them other than possibly trim over hanging branches. That means you can if you want but if you want them to take responsibility, you need to tell them.

It’s not always shown in a lot of detail on the title plan. The solicitor also doesn’t go to the property to measure and check the boundary.

@Onelifeonly Where does the op say she’s pretending they are hers? The former neighbour skirted the fence round them! Not the op! She knows they belong to the neighbour!

Go round, say hello, be friendly. Among other things "btw ha ha the former owners put a fence in not quite the right place, do you want a foot of land back? And technically those are your trees. Let's leave things as they are for now? Good good."

I would say 'those are your trees' leave out technically
