A couple from the northern Indian state of Uttarakhand are suing their only son and wife for failing to give them a grandchild after six years of marriage.
Sanjeev and Sadhana Prasad, 61 and 57, say they used their savings to raise their son, to pay for his pilot training and a lavish wedding.
They are demanding compensation worth about 75 million shillings ($ 650,000) if no grandchildren are born within one year.
The very unusual case was presented with “mental abuse”.
Mr Prasad said he spent all his savings on his son, sending him to the United States in 2006 for aviation training for $ 65,000.
He returned to India in 2007 but lost his job and his family was forced to support him for more than two years, reports Times of India.
Shrey Sagar, 35, eventually got a job as a pilot. Her parents say they planned her marriage to Shubhangi Sinha, now 31, in 2016 hoping they will have a “granddaughter to play with” during retirement.
The parents say they paid for a wedding party at a five-star hotel, a $ 80,000 luxury car and a honeymoon abroad.
“My son has been married for six years but they still have no plans to have a child,” Mr Prasad said. “At least if we have a grandchild to stay with, our pain will be tolerated.”
The couple’s lawyer, AK Srivastava, told The National that the couple had requested the money “out of mental anguish.”
“It is every parent’s dream to be a grandparent. They have been waiting for many years to become grandparents.”
The couple’s application, submitted to Haridwar, is expected to be heard in court on May 17.
