Enquiries are the questions your solicitor raises once the contract pack and search results are in. Anywhere between ten and over a hundred is normal depending on the property. They exist to surface anything that could affect your ownership or your ability to sell later. Delays nearly always come from the same places: missing building regulations certificates, undocumented alterations, and slow replies from a freeholder or managing agent. If you are selling, gathering your paperwork before going to market is the most useful thing you can do.
