We have a vacant land and the land next to it (owned by my father's brother) was converted to plots and sold to some parties. Now, we have applied for a government survey, and the surveyor says that the neighbors' have moved into our land to an extent. To know exactly till where our land is in neighbors' compound/enjoyment, surveyor says we have to get rid of all the plants and tress that have grown in the neighbors' land so that they can take machine and check the points and all. These plants and trees are waste ones and grown naturally. No one have made any construction on any of the plots. Only one plot has a fence around it and other have no fencing or any kind of marking for the extent.
Now the doubt is, can we clean the neighbors' plots without informing them or sending any kind of survey notice? (The new plot owners' names are not updated in the survey records, so surveyor seems he can't send the notice to new owners). Will this become trespassing and they may take an action on us?
If we inform them, there may be a chance that they may not agree for cleaning and survey for some reasons. (Some owners may also know that they have purchased a occupied land). Please suggest your guidance on how to proceed. Thank you.
