The Football Association has agreed to a rebalancing of the number of teams in FA WSL 1 and FA WSL 2 for the 2017-18 season in the wake of Notts County Ladies folding.
The decision has been made to continue with 10 FA WSL 1 teams for the forthcoming 2017-18 season, which begins in September, ensuring there is even numbers in both divisions.
FA WSL 2 clubs are now able to apply for the remaining place in FA WSL 1.
The application process will require clubs to demonstrate how they will meet the additional licence criteria, financial and staffing requirements of FA WSL 1.
The decision, which will be made in June, will be based on the applicant clubs' skills in business management, youth development and marketing, as well as the quality of their facilities and their performances on the pitch in the past 12 months.
Before the Lady Pies' liquidation, there would have been 10 teams in WSL 1 for 2017-18, and 11 in WSL 2.
Everton can win the WSL 2 Spring Series title on Saturday, but there is no promotion and relegation between the top two tiers at the end of the one-off competition.
One of either Blackburn Rovers or Tottenham Hotspur, who face each other in a promotion play-off at the end of May, will join WSL 2 for the 2017-18 campaign.
