Secondly, my DH had 3 years of NI contributions and is now retired. .... He has SS contributions for > 30 years and has the meeting this week to apply for benefits. .......So my question is, what if anything can he do to get some benefit from the 3 years of NI contributions? .... I did read that his US contributions could be used to fill out his missing years of NI to get him a pension here too. Is this true?...... In the case that it can be done with no negative consequences, what do we have to do?
If he is at UK retirement age for the State Pension, contact them (UK DWP) and explain about the 30 years of US contributions. DWP will apply the US/UK Totalization Agreement, and he should receive a weekly payment for the 3 years only. It's my understanding he only needs 1.5 years of UK contributions to qualify for the agreement.
As a very rough example, if max UK years are 30, then he would receive 3/30ths of the UK weekly amount (£UK max / 10).
When talking to the US SSA folks, mention the 3 years UK. They may start the ball rolling, or they should confirm his right to apply for the 3 years UK State Pension.
There should be no WEP applied to his US SSA benefit resulting from the UK SP benefit. Does he have any UK company pensions?
