Technically it is not UDC who are asking for the amendments to be signed or you do not get your apartment as the contract is between you & The Land & not UDC. UDC are clever about this. Realistically we all know it is UDC who are pushing for these to be signed. Why would a developer when they are so close to getting their final handover cheques put forward a new addendum which favors UDC when they know this will annoy their customers more than they already are? They also know others have not signed this (Sabban, First Qatar) & they just want to hand over their apartments, get paid & move on as quickly as possible.

There is no financial gain for the developer, just hassle & delays.
