We will transfer the balance of the purchase price to the seller’s solicitor.  On the closing day we will have professional law searchers carry out searches in various official registries to make sure the title is still “clean”.  Assuming these are clear we will notify you that the keys are available for collection from the office of the estate agent.  To allow time to make the searches closing usually occurs mid to late afternoon.  You should check with the agent in advance how many sets of keys and what keys (e.g. for internal doors) are available.
