A couple in India is suing their only son and his wife on the grounds of “mental harassment” for failing to give them a grandchild after being married for six years.

The parents, identified as 61-year-old Sanjeev and 57-year-old Sadhana Prasad from the state of Uttarakhand, said their savings have run dry after paying for the education of their son, Shrey Sagar, 35, and taking care of his wedding expenses.

The parents are now demanding compensation of nearly $650,000 or a grandchild within a year’s time, BBC reported.

“I have only one son. I spent all my savings on his upbringing and education. I sent him to the US in 2006 for a pilot training course,” the father said and claimed he spent nearly $65,000 on the course, according to The Times of India.

The son returned to India in 2007, but reportedly failed to find a job for two years, during which time the parents supported him, Sanjeev said.

After the son got a job, the parents eventually decided to get him married in 2016 “with the hope that we would get us a grandchild to play with in our retirement age,” the father said, according to the outlet. “However, almost six years have passed and there is no child. We are facing immense mental harassment.”

Sanjeev also told the outlet their son and his wife were currently working in two separate cities. He added he and his wife were willing to raise the child.

“We killed our dreams to raise him," the couple said in their petition, according to The National. "We even took a loan of 2m rupees for his education.”

"But despite all our efforts, my son and his wife have caused mental torture by not giving us a grandchild. The society also questions us, causing further pain," the couple added.

"They have demanded the money because of mental cruelty. It is a dream of every parent to become a grandparent. They had been waiting for years to become grandparents," Arvind Kumar Srivastava, the couple’s lawyer, told the outlet about the lawsuit.

“They had been trying to convince the son and his wife but they paid no heed to their demands,” the lawyer went on to say. “They are heartbroken that they will die without seeing their grandchild."

The couple filed their plea in the city of Haridwar, and their case is expected to be heard by a court on May 15.
