One thing I wish I had thought through more fully was post separation financial management. I have a 401K with employer match. I contribute a larger percentage than my employer. If I had been thinking, I would have reduced my match to the employer's level and instead directed the excess savings to a new and separate retirement account opened post separation. Instead, I have been inadvertently splitting my excess contributions for a year now.

A question I have is whether you could have your employer pause your bonuses and contributions until the divorce is final?
