Partnership ownership split - what is fair ?

[Westin Hudnall]

For the few 2 years of my business my business partner (my mother and law) and I have always been 50/50 partners. My Wife has been helping quite a bit with paper work and other aspects of the business and my mother in law wants her as an owner on the operating agreement.

Is it right and fair for my Wife and I to be 50% ownership since we are one in the same and mother in law to be 50% or should we all be 1/3rd ?
