Yup.

It’s all about who owns the domain name.

The recognized owner controls the DNS records and can point the site. Anywhere they want. Access to the current site is not needed, ever.

If she registered it in her name and not the organization you’ll need to challenge in court.

A simple letter from the organizations attornies may suffice, or not.

Depends on how bitter she is.

Point of order, is it the actual site she refuses to give access to or the domain registrar account where DNS is managed?

If it’s the registrar account she is holding hostage that may be solved with a phone call. Assuming of course that the organization pays the bill and not her.
