As I understand it, its a legacy thing that is no longer allowed to new claimants so the answer is both yes and no. It was one of those things that used only to apply to women and was stopped when the women’s pensionable age changes started but they may have changed their minds again and may cgange yet again in the future, also it may be different if its serps and not state pension. Not sure if its all settled down now but a couple of years ago when I was trying to get a forecast for mine, it was changing from week to week and I basically got told, yes you can get a credit from your husbands contributions, no you can’t, and then we won’t be able to tell you till you actually claim.
