Me and three friends want to start an investment club using a partnership agreement.
We're all young professionals and are completely new to entrepreneurship and the business world in general.

With that in mind my question(s) are:
- Is a partnership essentially a tacit agreement i.e. we don't need an attorney to create a contract for us?
- How do we register our partnership at SARS?
- What documents do we need to fill out?
- Do we need a joined bank account (cheque account) before getting a tax number or is it visa versa?
- Once we have a tax number and bank account can we open up a brokerage account under the partnership?

Any help and advice is welcome, thanks in advance!
