Relationships between the owners and occupiers of properties, both residential and commercial, can be fraught with problems. There is a raft of UK legislation governing the rights and obligations of residential landlords and tenants, which supplements the contractual relationships between them. The terms of leases typically cover parties’ obligations, such as who is responsible for repairs to a building; how it may be used; and how and when rent will increase. Despite this, disputes arise regularly. Lawyers encounter all kinds of problems from bankrupt restaurateurs with back rent to pay to unlawful sub-lettings and the mysterious appearance of a roof extension or cellar. More recently, lawyers have been dealing with issues arising as a result of the covid-19 pandemic, including tenants/businesses unable to pay rent. In the field of housing law, much of the work relates to the statutory obligations of public authorities to the poor or homeless.
