The Mexican Senate Social Security Commission unanimously approved a draft reform to the ISSSTE law. This reform aims to guarantee widowhood pensions for partners in concubinage, addressing previous unconstitutional restrictions regarding equality and non-discrimination. The proposal includes rules for distributing benefits among multiple claimants until a judicial resolution is reached.

Regarding 2026 benefits, regulations specify that IMSS pensioners under the Ley 73 regime are entitled to an annual bonus equivalent to one monthly pension. Additionally, certain IMSS beneficiaries may need to undergo survival verification processes to prevent the temporary suspension of payments.
