This is a statutorily defined document.
It relates to residential tenancy law.
Under normal residential leases, rent increases are permitted. However, tenants may be able to dispute a rent increase if there are sufficient grounds under residential tenancy laws.
In many countries, these disputes are referred for arbitration, or mediation to the statutory authority, depending on courses of action available under the applicable laws.
The example in this case is a tenant on a fixed income who wishes to dispute the rental increase based on ability to pay. The tenant is hoping to negotiate a waiver of the increase or a lower amount payable.
Note: This correspondence should be conducted during the statutory notification period prior to the actual date of increase in rental. The tenant is technically liable for rental incurred after proper notification of the increase.
