The incident is believed to be the first lawsuit filed in connection to the disaster which led to the disappearance of 239 people on board.
The suit was filed on behalf of two minor sons of Jee Jing Hang, who was among the ill-fated passengers. The family sued Malaysia Airlines for breaching of contract, saying the airliner did not carry out its responsibility to reach Jee to the destination.
The family would seek damages but the figure was not specified, sources in the family's legal team said.
A massive search operation was launched by several countries and across a vast geographical region across the Pacific Ocean but in vain. Neither the Malaysian government nor the airliner revealed results from investigations that were carried out in the wake of the tragedy and said throughout that only the recovery of the lost Boeing 777 aircraft would answer all questions.
