Popsi, you have a problem, my friend.
There are nine TRUE community property states in the USA.
Those nine states are: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin.
Alaska is an opt-in community property state that gives both parties the option to make their property community property.
You see, my new friend Popsi, Mississippi is not among those nine community property states.
Mississippi, as I mentioned, is not on this list of community property states.
In those states without community property laws, the property acquired during the marriage is divided equitably between the divorcing spouses.
Equitably doesn't equate with equally.
An equitable distribution doesn't mean that each spouse will receive an equal share, they could receive some share, an equal share, or no share at all.
In some cases in those non-community property states (ie...your Mississippi), the judge presiding over your divorce may order a spouse to transfer separate property to the other spouse to make the divorce settlement fair for both of them.
In other cases, no such order is issued.
So, after all that blabbing, Popsi, we get to you.
From what you say, no such distribution (equal or equitable was ordered), insofar as your divorce is concerned.
One could infer the legal conclusion that you were simply allowed to live in the home for the last decade out of kindness.
Fast forward to 2015, and your former spouse now seeks to have you removed from HER home.
You can demand it all, demand half, it won't matter.
She is legally entitled to ALL of the profits she can muster.
You have no legal claim to any of HER money, sorry.
Here you go, some reading for you on the subject:
