Are spouse docs needed to apply ILR THROUGH DLR (6 years)

[Allis1977]

hi all,
I got married to a British citizen in 2011 and got DLR for 3 years expiring on 3rd October 2014,then for further extension I submitted my application with all my relevant docs.
I also submitted my spouse and in my name joint bills etc with an attested copy of my spouse British passport
with my application,i was given another 3 years dlr expiring 2017 in October.
Now i'm asking that whether I will need my spouse British passport with my application or not as I have got all other docs in our joint name eg council tax biil,water bills etc ,or it is must to send my spouse passport with my application again?
many thanks
