Boundary wall

Other

The Landlord who owns the property next to the one I rent out says that the wall that separates our properties is unsafe (it leans a little towards his property) He also says that it is my responsibility to repair it. Of course if that is the case I will do so but I am unsure as to who is responsible. I have downloaded from Land Registry site the Title register and this is what I found regarding this matter. Can anyone convert the following into something I understand? Thank you

South Easterly sides thereof respectively are mesne or party walls and
fences and shall at all times hereafter be used and enjoyed and
maintained and repaired accordingly."
