Here’s a nice article on Top Financial Divorce Mistakes from Forbes.com.
Here are some of the mistakes the author, Leah Hoffman, names:
Having unrealistic expectations
Not communicating (with your spouse and your lawyer)
Getting into an endless battle
Getting hung up on the numbers (for example, believing that the financial split must be exactly equal)
Focusing on the present and not on the future
Forgetting to account for taxes
Overlooking important information (for example, about retirement plans, assets, and (I would add) all the debts and who owes them)
Staying too entangled financially with your ex-spouse
Failing to allow time for a dormant career to get back on track
It’s a nice list.
