Ask the vendor or estate agent? Sometimes it is to cover the look of a group of properties such as fencing for front gardens, not parking caravans or camper vans on the drive and so on. Even so it may not be enforceable as the other party may no longer be around.
Your solicitor should be able to find this out for you (before you get to exchange). Most can be dealt with by insurance. Why did the previous covenant cause your sale to fall through? (I’m not really understanding why it would be a good thing not to know what the covenant concerns).
Download the deed that the covenant is in. It should say in the register which deed that is and be listed as a referred document on HMLR website. Then ask your conveyancer to advise you regarding the covenants in the deed.
What happens is that when the property was unregistered one of the old deeds refers to covenants contained in am earlier conveyance but then a copy of that conveyance isn't submitted at first registration, in all likelihood it is lost.
You can get insurance for the loss in value but it doesn't get rid of the unknown covenant.
In my experience of last time the vendor didn't know. We couldn't get insurance because she stupidly approached the ancestor of the beneficiary.
I eant to know where the solicitor found out what this covenent was. On the deeds it was just 'subject to a restrictive covenent' bit then another document appeared 8 weeks later.
I thought there might be anotjer register I could look at.
I can't face shelling out AGAIN for legal advice/conveyancing that just ends up with me writing a big cheque and still ending up with no house! This would be the 4th house we have tried and failed to buy.
