2. Check if it has been 12 months since the last increase

Look at the date the increase is to begin and the date your last increase began. If this is the first increase, look at the date of the increase and the date you moved in. If there are not at least a full 12 months between the two dates, the increase is probably not legal and you don’t have to pay it.

A full 12 months means from any date to the same date the following year, for example, January 15, 2017 to January 15, 2018.
