If they mean the seller has completed a lease extension and waiting for it to be registered - that shouldn't necessarily delay your purchase.
It's not an extension, just registering the change in owner/occupant I think?
My solicitor's words:
once signed and dated, the ‘new’ lease is that which applies to the property, as this lease will either include the surrender of the previous lease and grant of the new one, or it will be a deed of variation which simply changes the previous lease. Upon completion, this lease has to be registered with Land Registry as it is a legal requirement to do so, hence the ‘new’ lease being with Land Registry.
I guess I need to push the seller's solicitor somehow.
I'd suggest you have a chat with your solicitor as it sounds like they haven't explained the situation very well. Like I said, Land Registry can take ages to register a new lease but it shouldn't necessarily hold up the other parts of the conveyancing process.
