They play in the Women's National League, the top tier of women's association football in Ireland, and play their home matches at Markets Field, the same ground as their predecessors.

Treaty United was confirmed as the name, and the women's team was ready to enter the 2020 Women's National League season and the men's in the 2020 League of Ireland First Division, but the men's team pulled out of the 2020 season.

The women's team, however, was ready for the season but had to wait until August because of the COVID-19 pandemic.

They started their season on 8 August 2020 against reigning champions Peamount United, losing 5–0.
