Alison sometimes the county sites are a bit slow to update things so if your owner has recently bought it may be that the site hasn't got their information online yet,Or it could be that it is owned by more than one person and it is registered under the other owners name or the person you are dealing with simply handles the bookings for their parents for example.One other alternaitve is that it is registed in the name of a company they have set up .I would offer my help but I am off to Spain for a week today .Don't wory I am sure all wil be ok .Start as Kilee says and go from there.
