My agent is dubai property link and was very clear with all aspects of handover from building owners. Basically you should show receipts of all payments made to them in respect of land dept charges, maintenance charges and miscellaneous charges(affection plan, processing fee, liason fees) and then you meet up with them at the building and get your keys from the representative in dubai. Well this is my experience but I am in dubai right now so it is better to find out from your agents what set up is arranged from investors away from UAE.Tip: Takeout printouts from any transactions online and keep them safe.
