This describes how beneficiary designations generally work. The details differ by country, state and province, and by the kind of account. It is general information, not legal or financial advice about your own affairs. The one action it suggests — checking your own forms — is free and involves no decisions.
A will. Written, signed, witnessed, and filed away with a feeling of something settled.
Some of your money will not follow it.
Anything with a beneficiary named on the account itself. Pensions and retirement accounts, life insurance, and often bank accounts set to pay on death.
Your will says one person; the pension form names another. Who receives it?
The account is not really part of the estate. It has an instruction attached to it that takes effect on its own.
The will governs what is left after all of those have done their work.
It is faster, and it skips the process of settling an estate.
That speed is the reason the mechanism exists at all.
Because the form was filled in once, years ago, and never looked at again.
People marry, divorce, have children, fall out, and the form does not know.
A pension naming an ex-spouse, decades after the divorce, while the will leaves everything to the current family.
The form wins, and there is no argument to have.
Which document usually decides?
Tap an item, then a bucket
There is no annual letter asking whether the name is still right. The form sits in a file at an institution you may not have contacted in years.
Make a list of every account that could have a beneficiary, then check each one.
It is an afternoon, it costs nothing, and it is usually a form on a website.
A marriage, a divorce, a birth, a death. Those are the moments the forms go out of date, and they are the moments nobody is thinking about paperwork.
A will does not control accounts with a beneficiary named on them. Those forms usually win. And almost nobody has looked at theirs since the day they signed.
