Do I need to include joint assets on surrogate papers.

My father passed away without a will. I am now trying to fill out surrogate papers to get the short certificates. Myself and my minor sister are the only living relatives. My dad was not married. My dad has some assets that are joint with his brother. His mother passed away and left my dad and his brother a property, and estate money for them to split. It is not solely in his name as it is in a joint account. Do I need to list these assets on surrogate court papers (Estate information sheet)? Or do I only list assets that are solely in his name?
