Completing Form CF83

Hi there, My partner has been advised by the Pensions Centre that he has gaps in his National Insurance Contributions and has over the minimum number of complete annual NIC payments to apply to make further payments in arrears from abroad. He is also waiting to receive a statement from the Pensions Centre in the post. He is completing a [postal] CF83 form and would like advice regarding the completion of employment dates. There are a couple of instances where is unsure of the precise dates, although he can make a close approximation. He has contacted the relevant employer HR departments re confirmation of the right dates but is finding they are taking a long time to get back to him. Would it be acceptable to complete dates as an approximation and note this on the form, and then post the confirmed dates at a later date to be attached to the submitted form? Any advice you can give is much appreciated.

...also my partner has started completing CF83 but is unsure whether he is completing it correctly. His circumstances are that he lived and worked in the UK from 1998 to 2009, and became a UK permanent resident during that time. He was born in Australia and lived there until moving to the UK. Since leaving Australia in 2009 he has been living in Australia. My queries are: - should he add his first and earlier employment in the UK to the form? He has only added his last job which was for over three years before leaving the UK? - He has put he was ordinarily resident in the UK before leaving for Australia in 2009. Is this right taking into consideration he lived and worked there for over 10 years and was married to me? Also, the form asks when he started living in Australia - does this mean the date he went back to Australia? Or should he put his date of birth here? This part of the form doesn't seem to make sense, and I wonder if he has filled out something wrong. Thanks for your help

Hi,
If your partner does not know the exact dates, it would be acceptable for him to provide approximate dates and advise us that these dates are approximate. 
Thank you.

Hi Lulu Farrow,
Your Partner should add his last employment in the UK at question 16 of the CF83, we will be able to check his National Insurance records to see his previous employments.
We need to know the date that he left the UK, therefore he should provide the date that he left the UK to return to Australia, not his date of birth.
He can also attach a covering letter to his application to explain anything in further detail if necessary.
Please refer to the NI38 when completing the form - Social Security abroad: NI38
Thank you.
