2 directors, different dividend amounts

Can't believe this...

20 years contracting. 3 companies. 3 accountants and not one of them advised me that my arbitrary dividend taking where most years I take nothing but the wife takes between 10 and 20k is actually wrong!

Apparently, because we have ordinary shares and are 50/50 in the company, I MUST take the same dividend as her.

Anyone find themselves in the same situation in the past? I don't know how to face this.
