The by-elections have been called following the resignation of Gail Turner from both Ashfield District Council and Nottinghamshire County Council.
The long-serving councillor stepped down from the authorities due to her sister’s deteriorating health.
Announcing her decision last month, she said: “This has been a very hard decision for me.
“However, my sister has become increasingly ill with severe muscular dystrophy and I am having to spend much more time caring for her, in Cheshire where she lives.
“I feel unable to provide the genuine and full-time level of representation I have always prided myself in giving and which residents deserve.”
The former Selston Parish Council member served the district council for 12 years as Selston ward member and spent six years on Nottinghamshire County Council, serving Selston division, representing Selston Independents – Putting People First.
The by-elections will be held on Thursday, November 26, with five candidates standing for each seat, including one man standing in both.
Standing for the Selston ward seat on the district council are: Labour candidate Donna Gilbert, of Lime Tree Avenue, Kirkby; Christine Quinn-Wilcox, of Lilley Close, Selston, for the Selston Parish Independents; Conservative Michelle Sims, of Green Farm Road, Selston; Independent Anna Wilson, of Blackwell Road, Huthwaite; and UKIP candidate Ray Young, of Derbyshire Drive, Westwood.
