Most company types will have concrete details for defining ownership proportions (controlling interest) and/or assigned roles with broad but clear allocations of responsibility and authority. Hopefully you have similar contracts defining the rules of engagement with your angel investors. If you're worried about litigation and liability, fall back on what the concrete legal docs say you can do. If not done yet, step one should probably be updating the company docs to reflect the reality of the founder separation. This of course requires negotiation of an agreement with your cofounder unless you set things up where you have controlling interest already or want to outsource it to a lawyer. If you clarify the region, company type, and whether the separation was formalized, then folks might be able to provide more specific advice.
