Hi again, Lurker,
" My purchase contract is dated 17 April 06 and the LFO is dated 16 October 08. I was told by somebody that the LFO must be granted within 30 months of the purchase contract being signed - is this 30 month time limit a legal requirement?"
The LFO should be in place before completion. As to the deadline to apply for it, it is an administrative matter between the developer and the town hall; in general terms, it is not relevant in order to cancel the contract.
"2) My LFO states that the architect's report was issued on 24 October 08, 8 days AFTER the LFO was issued. How can the LFO be issued before the architect has reported on the state of the building? - if point 1 is true, then is it legal to back-date the LFO in this way to cover the developer from legal issues that may arise due to point 1?"
Yes, it is weird, the town hall's technician report should be ready before the decision is passed. Are you sure there is no confusion with another thing? The matter is worth investigating.
"3) My LFO also states that sewage (waste water) disposal has not been completed. There is no connection between my development and the general sewage system. It states that until the sewage paths have been connected to the general system waste water will be collected and transported by truck and disposed of in the relevant place by a named company. Should I be worried about this?"
YES. it is difficult without checking the project and the planning permission, but the Developer is obliged to achieve this and it could be a breach of contract. A good question would be to check who's paying this company, you or the developer...if it is you, then you can attack the developer in order for him to assume this charge and do things correctly.
