I entered into an agreement ( unregsitered) with builder in 2012 wherein it was agreed that the builder will give me possession after completion certificate in March 2014. He failed to do so as the project progressed slowly. In august 2014 , the agreement to sell was regsitered and redrafted but the clause dealing with date of completion was retained as such ( although the promised date of completion was already past). The project continued slowly and the builder abandoned the dwelling in 2015, although the construction was almost over but lift was not installed. I moved into the premises in oct 2015 ( in absence of formal possession letter) after getting the remaing work done out of my pocket. The building is complete now and the sale deed was done last month with formal handing over of possession as stated in the sale deed. Can I suit builder for damages due to delaying of project and asking for compensation from March 2014 till sale deed ( two years) . Completion certificate and occupancy is still not procured.
