Hi. No, you don’t need a lawyer to create a partnership, but on the other hand, that is what commercial lawyers do i.e. take the intentions of the people involved and write it down (or customise a document) to set out the rules and arrangements in a way which people can understand and to avoid arguments later. The type of agreement will depend on the type of partnership you want. Different lawyers also specialise in different types of arrangements. For example, I specialise in limited partnerships which is a particular type of partnership often used for investment funds, but if you wanted a simple partnership between a couple of people to run a business, I would refer you to one of my commercial colleagues.
