Lost deeds will result in delays; but nothing that cannot be overcome.
The reason I asked is my initial question is that the urgency of the situation dictates the next step. If the situation is not urgent, then the solicitor can take steps to re-constitute the title documents; She can perhaps get copies from third parties (depending on the title). Alternatively, if the title was a long leasehold, steps might be taken to buy out the freehold - which kinda gives the title a fresh start. A third option in the case of a registry of deeds title would be to start the process of applying to register the title in the Land Registry - difficult when your deeds are lost, but by no means impossible.
On the other hand, if you are about to sell or re-mortgage, there might not be time for any of the above, so you might need to take out a title bond - which is a form of insurance.
The club solicitor should be able to give all of this info.
