Sir, my husband worked in a reputed company of gurgaon, company told me that your husband did not change his nomination for claims and funds, (mother to wife) , thats why this problem occurs, company told me that claims and funds belongs to wife only but , if your mother inlaw is also expecting for money, than it should be 20% belongs to mother and 80% belongs to wife according to law. When i told about this rule to my mother inlaw than she refused and said if you also want than i will give you only 50% otherwise not. Sir, someone told me the judgement of supereme court, that the nomination made before marriage is invalid, after marriage nominee will automatically belongs to wife only, mother inlaw is only a care taker, when legal hier found then mother inlaw has to give all rights to legal hier, and for mother inlaw gratuity will be 50% .
