I used to register each property and land transaction made by our local Council (I worked in the Council's Conveyancing Section). I am surprised that your deeds weren't registered when you purchased the house as it is mandatory, maybe you purchased the house before registration was compulsory (in our area that was in the 1970s). If, as you say the property is unregistered, I presume there will be numerous documents that will need to be lodged with the registration application. Maybe you could google how to make the application, but I just wanted to warn you that if the house is old, it isn't always very straightford (as the house will probably have been bought and sold quite a few times and each purchaser's documents must be lodged alongside your purchase documents and you will need to establish that all is in order and all relevant documents are lodged). Personally, I would get a conveyancer or solicitor to do it and would be enquiring why the deeds weren't registered when you purchased the house.
