Partner details on Form AN

I am the only one in our household applying for naturalisation and was wondering if it is necessary to fill this section out if we have been in a relationship and living together with our child (who is British by birth) for nearly 3 years? It seems they only want details if you are married, in a civil partnership or divorced.

Also no section asking details of any children - should I add this to the page for extra info?

Thanks

Leave it blank.

Not needed.

Thanks!
