I assume from the original post that the property is in the West Midlands. If so, then in all probability the property will be registered at the Land Registry as compulsory registration applies to an almost all-inclusive list of land transactions these days, and the West Midlands was one of the first counties in which full registration was achieved by the Land Registry. Your solicitors will be requesting the title number of the property and will be routinely obtaining official copies of the register and the title plan before you proceed with the purchase, and will be able to supply you with these. If they try to charge you, it will almost certainly be much cheaper to apply for your own copies. (Not up to date with charges, but probably less than a tenner for a set). Anyone can request official copies from HM Land Registry.
When you read the register, as far as ownership is concerned, it will show only the current registered proprietor. Extracts of various relevant title deeds may be set out on the register though, or various deeds might be referred to as being "copy filed". In the latter case, you can order a set of official copies of all deeds referred to on the register as being "filed". Generally, the older they are, the more interesting they are, and some of the older conveyances and leases contain interesting old plans as well as referring to various previous deeds and parties that might be of interest to you.
