1. Total constructed area as per the agreement was 45000sqft. whereas builder has increased it by another 1600sqft. and as per agreement we are entitled for 30% of the additional constructed area. But he is denying that completely. What is our option?
If your agreement contains this clause, you can very well point it out in your legal notice demanding your rightful share in it after which you can initiate proper legal action through court for recovery.
2. One of my uncle who was one of the parties in that agreement passed away last year. His wife, a son and two married daughters are now the legal heirs of the portion as there is no will. After he passed away last year his wife,son and 1 of the daughters gave their POA to the builder and the other daughter couldn't make it as she was pregnant. But the builder has completed multiple sale deeds without her authorization post my uncle's death. Kindly advise on the actions we can take against the builder and the parties in that sale deed who bought the flats?
The affected party i.e., the legal heir who has not authorised the builder to sell her share through a POA deed shall sue the builder for this and can even obtain an order of injunction in further issues as well as she can file a suit for cancellation of the alleged sale deeds. She can even prefer a police complaint against the builder for having sold her share in the property without her knowledge or consent.
Consult a local advocate and initiate proper legal action agaisnt the builder in this regard.
