1. Dear members, as per section 46(2) of ESI Act, 1948 , family of the insured person is entitled for medical benefit (facilities) from ESIS institutions on certain terms and conditions as laid down in ESI Act, 1948 and rules/regulations framed thereunder. As per section 2(11), the term "family" does not include father-in law, or mother-in law. Therefore, these relatives are not entitled for medical facilities on the basis of ESI entitlement of their son-in law or daughter-in law. However, if their own son or daughter is covered under ESIS, then naturally they will be entitled for medical facilities from ESIS as part of "family" as defined under relevant section as mentioned above.
2. However, section 2(11) stipulates that the parents must be "dependant" and their income from all sources should not exceed as may be prescribed by the Central Govt. A limit of Rs. 5000/- per month has been laid down by the said Govt. in Rule 61-A of the ESI (Central) Rules, 1950. Therefore, the parents whose income from all sources is exceeding to Rs.5000/- per month are not entitled for ESIS medical facilities even though they may be part of "family" as defined under said Act.
