How to break up a partnered search?

Hi, Searchfunder community - I am asking this question on behalf of a searcher due to the sensitivities around the situation.

Their search started out as a partnered or duo search. One searcher is moving on to another opportunity, while one searcher wants to continue with a solo search. The searcher would like to know how others have navigated the situation in terms of restructuring the fund, the legal documents and any negotiation terms to be aware of. They'd also like to know how to address the situation with their investor base.

Please respond below, write back to me here or send an email to redacted

If you know someone who faced this situation, please point them to me as well.

Thanks, all! Warmly,
