Shared contributor account as a company

No you cannot collect royalties from assets that are also on another account. One or both of the two accounts will be closed.
If you want to move your assets from the shared account, they must be deleted and resubmitted.

Thank you for all the helpful answers.

What happens to the existing account is not important for me at the moment. The important factor for me is whether I can open a new account as a new contributor on Adobe with my own name and not as a company. I would not upload my old works to the new account, but new ones of mine that do not exist in the old one. Maybe sometimes they would look similar, but definitely not the same. After all, my graphic style hasn't changed. Would it be possible at Adobe? Otherwise, I'll write to customer service directly. I just thought someone here might know about this. Thank you all!

And this, boys & girls, is why all Contributors should have SEPARATE accounts from day #1.

Stuff happens.  Partnerships dissolve and people go their separate ways.  Combined accounts are a messy business for everyone.

You can't duplicate content on another account. You'll be in violation of Stock's Contributor Terms if you do.

Talk to your lawyer.  He can advise you better than we can.

This asks for context that is by far more complex than to discuss here in this public space.

But this is my appreciation:

• As the company operates the stock account, the company is key.
• The stock account is an asset like any other asset you own (car, house, stock, savings, ...). It should be split like all other assets. And as you can't split the car in two, you can't split a stock account in two. It's not foreseen, as of my knowledge.
• The stock assets belong to the company (I suppose that is the current legal situation).
• If the company gets acquired by one person, the other person will be idemnified for that.
• One or the other or both can create a new stock account, where they contribute exclusively own assets.
• You can't upload assets in one stock account to the new one, in addition to keep them in the old one. If you want to do that, you will need to delete them on the other side first. Current customers will be pissed off. 

It sounds like you're not willing to transfer the copyright for the assets you generated to your spouse. Therefore, I think your next step is to delete your assets from the shared account so that only his assets remain, and resubmit them to your new account. If your assets have generated more sales than his, it might be better for his assets to be deleted and yours retained so that you don't lose the sales history and search ranking of those images. Either way, a discussion with an attorney is necessary. 

I'll preface by saying I'm not a lawyer, so take the following with a grain of salt. You are the copyright owner of any images you submitted to the "company account." If your ex continues to sell them, the proceeds need to go to you. If your ex wishes to gain from them, you would need to hash it out with your lawyer(s) to transfer copyright ownership.

I think.
