B and L have formed a partnership even if they did not intend to.
Explanation:Partnerships can be formed in several different ways and can offer an attractive alternative to setting up as a company or a sole trader.
A partnership is the relationship of two or more 'partners' carrying out a business with a view to making a profit. You and your partners are responsible for running the business. You share profits between yourselves. You and your partners are personally responsible for paying the bills (apart from LLPs). Partnerships are not a separate legal entity (apart from LLPs).
