An emotional video has emerged from the US of a man being reunited with his biological mother for the first time.

The footage, captured at a home in Nueces County, TX, on July 23, shows the man meeting his mother after 49 years apart.

''At the age of 20, my mother was forced to give up her son for adoption at the aggressive hands of her mother and father,'' the filmer later wrote online.

''Her son had been searching for her since 1989,'' he added.

At the age of 20, my mother was forced to give up her son for adoption at the aggressive hands of her mother and father. Her son had been searching for her since 1989. When he finally found her, I caught this magical event on my phone. Adding to the mystic of the situation, my mother passed away a few days after meeting him. She was loved by many and shall be missed. Love you Mom.
