Long story short. MIL passed away recently and we thought we had a sale sorted for her flat which is above a commercial property. Spoke to the buyer and he says his solicitor has pointed out that the loft space is owned by all 4 properties (2 commercial below, 2 flats above) and that means the commercial properties could, for example, say they want to use the loft space as storage and we would have to grant access. However, the only way to access the loft is from MIL's (or neighbouring) flat. So surely this can't be true? They are now concerned and I think reconsidering buying based on this information. Our deeds state a servitude right of access but all google info about this related to land and gardens etc, not actually entering someone's home?! I understand access for repairs to roof or in emergencies but surely no more than this?
We have been in touch with our solicitor today but they didn't reply until near close of business so no time to clarify points. They did confirm the loft space is listed as common.
Google has also led me to read about negative prescription and rights being extinguished after 20 years, no one has entered the property for access in more than 20 years but would this apply in this instance and we have no way to prove it?
Can anyone please help?
