How important is the Title Plan?

Hi everyone,

We’re FTBs and its been already 5 months although the seller is also chain free. Almost everything is done and we arranged an exchange date for the next week. However, our solicitor informed us sellers solicitor hasn’t been provided an Official Title Plan yet and we think we need to wait for it. However the seller is threatening us with pulling out and they say we should exchange as it is without having official title plan.

How important is this document? We are really upset and trying everything to close the deal before the end of March and EA is now ghosting us.

We could really use your suggestions. Thank you.

Edit: THANK YOU SO MUCH EVERYONE!! WE’LL NOT EXCHANGE UNTIL WE RECEIVE THE OFFICIAL PLAN.
