Packiam Ramanathan, 73, attacked her 76-year-old husband, Kangusabi Ramanathan, at their home in Burges Road, East Ham, on Friday, 21 September.
She was found not guilty of murder by a jury but had previously admitted to manslaughter on the grounds of loss of control and was convicted at the Old Bailey on Monday.
The couple married in Sri Lanka in August 1983 but eventually left due to a civil war and moved to London in 2007.
Ramanathan claimed years of arguments over food and money during their 35 year marriage was one of the reasons she lost control.
But, she had previously told members of her family and other witnesses that “they had never been physically violent towards each other.”
Tensions rose when Packiam discovered her husband had written a letter to police in Sri Lanka, accusing her brother of “cheating” and refusing to return gold jewellery and land documents to him.
She told a relative she would “not watch idly” if her brother was harassed by the police as a result.
The body was discovered when a relative of Kangusabi noticed he hadn’t called them as usual and decided to check on him in the flat at around 1.20pm on the day of the assault.
When she went inside, she saw Kangusabi lying on the bed and Packiam told her: “I have hit him, beaten him. He died.”
Shocked, she called her husband who phoned an ambulance and went to the home where he found Kangusabi’s “head full of blood.”
Paramedics attended the victim at around 2.20pm and estimated he had been dead for three hours.
Packiam was arrested at a friends address in Wimbledon where she attempted to hide a handbag containing her passport, a large number of Rupees, £670 in cash and personal items.
Sentencing will take place on Friday.
