What happens while it is decided
The process from here
This application is with Elmbridge for determination. The council publicises it, consults neighbours and technical bodies where required, and weighs the responses against local and national planning policy.
The statutory target is eight weeks for most applications and thirteen for major development, though extensions of time are common. Comments carry most weight while the case is undecided, so check the council portal for the deadline if you want to respond.
About lawful development applications
How this application type works
A lawful development certificate is a legal determination, not a planning judgement. It asks the council to confirm either that existing use or works are lawful, often through the passage of time, or that a proposal would not need planning permission at all. The applicant must prove the facts; the merits of the scheme are not considered.

17 Green Lane Cobham Surrey KT11 2NN
Tree Preservation Order EL:25/02 - T1 Scott's Pine in Rear garden-Fell Tree is in a very poor location, in very close proximity to the house and neighbours Driveway. Client has suspicions of tree causing subsidence. Prior to the Tree gaining a tree preservation order, the tree had started to get dismantled, with many of the lower branches "flush cut" to the main stem and also Spur marks to gain access into the canopy. There is a large Defect at the base on the house side of the tree, from where a section of the bark is removed and damaged the Cambium, to enable the friction/lowering device to be fitted. I imagine these defects may end up leading to decay or decline and due to the tree being within striking distance of there house and also the neighbours garage, it may become dangerous in the near future. Due to this, I would like to apply to Fell the remainder of the Tree and replant a suitable Replacement in a better position within the garden.
