We have a house on a small plot of 5 houses which have a restrictive covenants put on them in 2002 by the builder not to erect a fence, hedge etc at the front of the property. However we want to put up a fence to stop the neighbours from coming all over our front garden which is in front of our dining room and also to hide their bins which are at the side of our house and are accessing from our garden. We have tried to contact the original builder but he went into liquidation in 2020. Therefore are the covenants still valid, and if so who can enforce them and what could we do?
