The family of Perth man Paul Weeks, who was on the doomed Malaysia Airlines flight MH370, is suing the company for damages.
Five writs were lodged on March 4 in the West Australian Supreme Court - four days before the second anniversary of the plane's mysterious disappearance and just before the statute of limitations was reached.
Mr Weeks' wife Danica, sister Sara, brother Peter and mother Prudence Tomblin are each claiming compensation for "personal injury, loss and damage" suffered as a result of "sudden shock" and "mental harm" after his death.
Danica also launched a separate legal bid on behalf of their two children - five-year-old Lincoln and two-year-old Jack - covering lost earnings, financial loss, funeral costs and damages for the loss of his luggage.
The family is also claiming for six per cent interest on damages per year and reimbursement of their legal costs.
The Boeing 777 aircraft vanished shortly after taking off from Kuala Lumpur bound for Beijing on March 8, 2014 with 239 people onboard.
