The Armed Forces Tribunal, Madras Region, has ruled that a woman who lived with a retired army man for about 24 years was entitled to family pension. 

The Bench said, “The Supreme Court held that if a man and woman are living under the same roof and cohabiting for a number of years, there will be a presumption that they have lived as husband and wife and the children born will be legitimate.”
