How to properly spin off a subdivision of an existing company?

[rzettle2525]

An existing client of mine is the parent of a subsidiary. The parent business  currently drives traffic for the subsidiary and has been doing so for many years. The subsidiaries owner is wanting to create their own website even though the companies are still in great relationships.  So I'm wanting to make sure they don't compete.

What necessary steps do I need to take? My one major issue is the address. They both work under the same address and I plan on using a suite number for the subsidiary.  Will that work? Even though the parent company doesn't priortize it's subsidary business for SEO, I don't want to drop in rankings and for them to compete.

Any knowledge or insight on this would be greatly appreciated! The more details the better Thanks!
