Farooq Abdullah filed his nomination at the office of Srinagar District Development Commissioner Farooq Ahmed Lone, the returning officer for the constituency.
He was accompanied by his son and former Chief Minister Omar Abdullah and Congress leaders G.A. Mir and Tariq Hameed Karra.
When PDP's Nazir Ahmad Khan filed his papers, he was accompanied by senior PDP leaders Muzaffar Hussain Baig and Imran Raza Ansari.
The seat fell vacant after Tariq Hameed Karra resigned from the PDP and the Lok Sabha last year.
Karra later joined the Congress and would campaign for Farooq Abdullah as the National Congress and the Congress are fighting the by-poll jointly.
