A bond is optional; if the lessor requires one it may be no more than the first 4 weeks' rent, and only one bond may be taken for an agreement. Where a tenancy rolls into a consecutive agreement with at least one continuing tenant, no new bond may be taken unless a bond release application has been made for the old one; otherwise the existing bond carries over. A guarantee or indemnity accepted with or instead of a bond is enforceable only up to the gap between the bond paid and the 4-week maximum.
