Leaders of 16 other parties who are vouching for Ms Kumar, including National Congress Party's leader Sharad Pawar, West Bengal Chief Minister Mamata Banerjee, CPI-M's Sitaram Yechury and Rashtriya Janata Dal leader Lalu Prasad are also expected to be present during the filing of nomination.
Ms Kumar will be contesting National Democratic Alliance's (NDA) presidential candidate Ram Nath Kovind who has already filed his nomination papers. The NDA has a clear edge in the election and Mr Kovind is widely expected to sail through.
In a statement on Saturday, she stressed that the post of President of India is "not symbolic" and that "capability and experience must always supersede" every other consideration while choosing the person for the post.
