Usually it depends on the condition in which your business is at that particular moment and this includes going bankrupt, needing more hands due to increasing duties and many others.
As your company grows bigger it requires more than one head or ideas and many other areas which you might not be an expert. Going into partnership with someone is something which requires considering things like sharing the same vision, passion, dreams and many more.
Being able to get along with your business partner you have to be in some kind of a relationship or what I would call a business marriage. Both of you have to be one body but different duties which all together with unity makes the business run smooth and effective.
Choosing a partner who does not share the same qualities just because you need quick cash to inject in your business could be very risky. It is not an easy thing finding a partner but there is always someone out there who has the same qualities and if you stay positive, they always avail themselves.
