Do they all become marital, and get divided 50/50 in a divorce?
Or should I spell it comingled?
It depends upon the assets and how they are commingled. Under most circumstances they do become marital - but simply because they are marital does not dictate a 50-50 split.

Mr. Browde is correct, it becomes a problem of tracing and how they were used.
My name is Stephen R. Cohen and have practiced since 1974. I practice in Los Angeles and Orange County, CA. These answers do not create an attorney client relationship. My answers may offend I believe in telling the truth, I use common sense as well as the law. Other state's laws may differ.. There are a lot of really good attorneys on this site, I will do limited appearances which are preparation of court documents it is , less expensive. However generally I believe an attorney is better than none.

Possibly. The question is whether the parties agree that some of the money is non-marital and then further can the claiming party prove non-marital. Each case is specific as to facts. For example, if you and spouse have a $5,000 savings and he inherits $1MM, you have $1,005,000 in the account. It would not be difficult to trace a large portion of that inherited money to be non-marital even though it is comingled. On the other hand, if you both deposit 10% of your check each month into an account and then you add in a $5,000 gift from your mother 10 years ago, it is likely considered comingled and equally divisible. You need the advice of an experienced divorce/family law attorney to review your specific case.
