Which itr to be filled

Sir,

My father has recently retired and gets no pension but gets monthly annuity from LIC from his superannuation.  In addition he works as a consultant on a part time basis and is paid Consultancy Fees with no TDS deducted at source.

Kindly advise me which ITR form to be filled up.

Can I fill a ITR1 Form. Would the annuity payment received be filled against "Salary/Pension" and the Consultancy Fees be shown against "Other Source of Income" alongwith the interest income received from his investment.

Thanks

Sunil
