I am often asked to help people do this, and typically, the pension company will issue their own form for you to sign in my presence after I have identified you. You would need to send your form in advance so that I can check it for you.
Pension forms do vary wildly, but typically they will have all your details on, which I will check against your passport and I will be asked to confirm that you are alive on the date of signature. Most require you to do this in person, a few will let us do this over video call, but this needs to be recorded on the document as the method used.
The frequency of this depends on where it is and if you are drawing a monthly or lump sum. The latter needs you to do this only once, and is most frequently requested from the Australian Superannuation. They usually request only your notarised identity documents. When it comes to European countries, they often want the form to completed annually or biannually. Some South African pensions want you to visit a notary every three-four months.
When it comes to pension documents, the first visit is always the current minimum fee, after which it is discounted by frequency of your visit. Annually is discounted to £60 and more frequently £45.
