Why skipping probate matters so much
My wife works in probate real estate, so I see the aftermath up close. In California, probate routinely takes a year or more, and the statutory fees come straight out of what the family inherits. Meanwhile, the deceased person's bank accounts can be frozen while the court sorts things out, but the mortgage, the funeral home, and the utility company all still want to be paid this month.
That gap (money owed now, money locked up for a year) is exactly where families get hurt. It's why a funeral so often ends up on someone's credit card.
How life insurance gets around it
A life insurance policy is a contract, not an asset of your estate. When you name a beneficiary, you're telling the insurance company who to pay directly. That payment happens outside the will and outside probate; it doesn't wait on the court, and the fees that eat into a probate estate don't apply to it.
That's the whole point of the tool: it puts cash in your family's hands within weeks, while everything else is still stuck.
The exceptions that catch people
Life insurance can get pulled into probate in a few specific cases, and they're all preventable. First: if you name 'my estate' as the beneficiary (or name no one at all), the money flows into the estate and through probate. Second: if your only named beneficiary has died and you never named a contingent (backup) beneficiary, the proceeds default to the estate. Third: if you name a minor child directly, the court usually has to appoint someone to manage the money until they're an adult.
The fixes are simple: name a person, name a contingent, and use a trust or custodian arrangement if minor children are involved. This is the kind of thing I check on in fifteen minutes.
