"The main issue is that at this age we need a grandchild, but these people [my son and daughter-in-law] have an attitude that they don't think about us," Prasad said.
"We got him married in the hope we would have the pleasure of becoming grandparents. It has been six years since their marriage," Prasad said.
"It feels as if despite having everything we have nothing."
The court accepted their petition and scheduled it for a hearing on Monday in Haridwar, a city in northern Uttarakhand state, media reports said.
The son and daughter-in-law could not be reached for comment.
Prasad said he and his wife love children.
"We are not getting love and affection from where we want it the most," he said. "I feel very unlucky."
