"People might say we are crazy, let them say so...," the couple said.
The monkey had lost its mother ten years ago to a bad fall and was adopted by the couple.
Now the couple has decided to leave their house, a 200-yard plot of land and all their savings to the monkey whom they consider as their son.
Brijesh Srivastava and his wife Sabista have no children, but they treat their pet monkey as their own son and have set up a trust to ensure the animal is looked after if it outlives them. Monkeys can live for 35 to 40 years.
The trust will use the money to feed monkeys that are forced to leave their natural habitats because of deforestation and wander into human settlements.
"We are childless and 'Chunmun' is a son to us. We want to ensure that even when we are not alive, Chunmun's life is not affected and he continues to live the way he does," the couple said.
They say the monkey has brought them fortune. When they adopted the primate in 2004, they were poor. Now they are prosperous, owning a house.
Sabista (45) is an advocate and her 48-year-old husband owns several businesses all named after 'Chunmun'.
The monkey likes to eat Chinese food and it also drinks tea and mango juice, according to Sabista.
