Presumption of Community Property

TX Fam Code 3.003 -- it is presumed that all property owned by one or both spouses is community property.  The burden of proof to make an item separate property is by "CLEAR AND CONVINCING EVIDNECE".

So if you inherit $50,000.  Put it in a separate bank account.  If you put it into the joint bank account, for even one day, it co-mingles the property.
