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, and these supplement 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 all this, disputes arise regularly and this is where lawyers step in to help resolve conflict. Lawyers encounter every kind of problem from bankrupt restaurateurs with back rent to pay to unlawful sub-lettings and the mysterious appearance of a roof extension or cellar. In the field of housing law, much of the work relates to the statutory obligations of public authorities to the poor or homeless.
