Who will own the rights to the application in the app store?

Question

Law in IT

The situation is this:
I came up with the idea of ​​a mobile application plus designed the entire architecture, design, business model and other points.
The partner acted as an investor and paid for the work of programmers.
The programmers signed an agreement on the transfer of rights to a partner.
The partner agreed that I would upload the application in the app store as an individual.
We will split the profit in half.
The question is, can it hypothetically happen that the partner wants to take this application for himself, given that he signed an agreement with the programmers to transfer the rights to the code?
Perhaps at this stage we need to conclude some kind of contract with the programmer?

Answer 1

The question is, can it hypothetically happen that the partner wants to take this application for himself, given that he signed an agreement with the programmers to transfer the rights to the code?

Yes. In the case of a court, your partner has exclusive rights to the code. And you can't dispute that.

Perhaps at this stage we need to conclude some kind of contract with the programmer?

No more to conclude. Typically, such agreements are concluded on the principle that the author loses the exclusive rights to the work, and cannot transfer them to someone else.
Judging by your previous questions, the contract is most likely concluded with an LLC, of ​​which you are the founder. So basically it's not scary.

Answer 2

You don't need a contract with a programmer - here, as Vasily Bannikov correctly noted , the train has left.
And between you and your partner.
Specifying the investments of each (as I understand it, from him - money, from you - a chair ... work) and the corresponding shares of each, plus the rules for the division of profit and loss (which can be very tricky, such as "up to a certain amount of profit to be distributed, the partner receives , say, 90%, and over a certain amount - 10 ").
For such an agreement, it is also somehow not very early, but it is still possible (and necessary) to do this.
