The new buyer need to know the contents spelled in the DMC, you only need to enclosed it together with the SPA when selling it away. There is no need to sign a new deed with the MC because the original DMC has become part of the house rules enforceable by laws. In the very old units, the car park allocation was mentioned inside DMC & not inside SPA, hence you need to enclose the DMC whenever you are selling away your strata unit. Also, the rules within DMC can be amended by the elected MC if they are able to gather sufficient quorum during the AGM. The DMC need to be read together with the latest amended house rules submitted & approved by COB.
