Have name changed for this for obvious reasons.
We live on a street with a history of people that have at various times appointed themselves sheriff of the road.
About ten years ago, the latest sheriff moved in, set up a What's App group which we did agree to be included in.
There is an area behind our houses where he claimed to have discovered some Japanese Knotweed. Helpfully, he posted this on the group.
Neither DH nor I are experts in this and IIRC we did agree to get involved in some treatment. None of this was directly behind our house but obviously it spreads if that's what it is. It was unclear if we ever got confirmation of that.
It was a dolt move, for sure, to have something like that on a public chat but at the time it was many years before we would have considered moving.
We're thinking of putting the house on the market.
Is this the sort of thing that would come up in a survey? Do I need to do anything if it was never confirmed?
