From family lawyer Sherry Donovan in the Huffington Post.  I agree with all of them, and I’d add an 18th: concentrate on what’s best for the children and yourself, not what might punish your ex.

I’ve warned many clients that they’re likely to come out much worse at trial than if they accepted a reasonable settlement offer, but some are so embittered that they want their day in court anyway.  If they’re particularly obstinate, I will tell them to seek other counsel.
