We were due to move a few weeks back ( expected completion dye was 2 weeks ago).
We are having major problems with the Seller's solicitors. Our solicitor has said we need a document saying that we can legally purchase the land that the property is built on. Their solicitor has messed us around telling us it is "in hand" they are now saying they will not provide it until we exchange.
Our solicitor has said that we cannot exchange without it as we won't be able to register the property in our name. He said he will go back to them today but this has been going on weeks and got no where. 
AIBU? What can we do??
