The Widow’s Pension was one of the oldest established part of the Social Security system in the United Kingdom.
Benefits for Widows were first established by the Widows', Orphans' and Old Age Contributory Benefits Act 1925 at a rate of 10 shillings a week for life, to stop on remarriage.
[1] To get any benefit as a widow a woman had to be married to her husband, and be his only wife, at the time of his death.
She was still entitled if separated or if a divorce had not reached the stage of decree absolute.
The claimant had to be over 45 but under 65 either when their husband died or when their Widowed Mother’s Allowance stopped.
