Online documents upload for OCI.. please help

Hello Everyone
Good evening
I have completed section A/B online now just about to upload documents online but don't know what to submit as I only have couple of documents from the list below.. anyone who recently applied please please help..!

1. Current Passport. ( My UK passport right?)
2. Proof of Indian Origin. ( Surrender Certificate..?)
3. PIO Card
4. Spouse OCI Card
5. Relationship Certificate
6. Marriage Certificate.

Do I have to upload Naturalisation Certificate or Indian passport or anything..??


Any help guiding me about documents that are mandatory to upload?

Thanks

Glad you have completed the top two sections.

Next step is to upload Image & Signature

Last step is to upload the documents.

Surrender Certificate
Naturalisation Certificate
British passport

Thats all they require.
