Legal advisor for children's climate education charity

Climate Ed, a children's climate education charity, seeks a legal advisor to provide guidance on international partnerships, specifically regarding a proposed affiliate in the USA. The role involves navigating legal issues related to collaboration with other charities. The position is remote, allowing work from anywhere, and no specific degree qualifications are mentioned.
We are looking for someone to help guide us over legal issues related to building partnerships with other similar charities internationally.

We are a children's climate education charity and we have been operating in the UK for four years.

We only have a remit to operate in the UK however a group in the United States have approached us to ask if they can set up an affiliate / sister organisation in the USA.

We are seeking legal guidance over how to manage such a partnership.
