Chapters 1 to 5 of this Part apply only to secure contracts, and address—
(a) variation of secure contracts,
(b) withdrawal of joint contract-holders,
(c) dealing (that is, taking a lodger and transferring the contract), and
(d) the imposition of prohibited conduct standard contracts (where the landlord is a community landlord or registered charity).
Chapter 6 contains a fundamental provision about transfer of a secure contract to a person who is a contract-holder under another secure contract; this fundamental provision is applicable to secure contracts under which the landlord is a community landlord.
