Congratulations — you got married. And now someone, a relative or the internet, is telling you to just put everything into one joint trust and be done with it. I understand the appeal: one trust, one set of rules, nobody has to think about who brought what into the marriage.
But if you came into the marriage with property of your own — a house, a brokerage account, an inheritance, a business — combining it into one joint trust without keeping track of what was yours can quietly cause real problems. Not now. Later, if the marriage ends, or when one of you dies. Here’s what that means in practice.
Problem No. 1: It becomes difficult and expensive to prove what was yours
Combining your property with your spouse’s doesn’t sort itself out later — it does the opposite. Once everything sits in one pot with no records, it becomes very difficult to tell what came from where. And whatever you might have wanted for that property — to keep it, to share it, or to leave all of it to your spouse — you no longer control the outcome. A court, applying California’s default rules, decides for you. Those rules don’t know your intentions, your inheritance, or your long marriage. They just run the formula.
(If you brought significant separate property into the marriage, a family law attorney should document it properly, so it stays yours without shutting your spouse out.)
Problem No. 2: At divorce, you pay to untangle it
If the marriage ends, you’ll have to prove — with actual records — what was yours, what grew from it, and what was spent from where. If those records don’t exist, the legal fees to reconstruct them can cost more than you were trying to protect.
Problem No. 3: At death, the state’s plan takes over
If you die without an estate plan, California already has one for you, and you won’t like it. Depending on who survives you — children, sometimes parents or siblings — your spouse can receive far less than you intended, and may have to share the estate with others. If any of them are minors, their share lands in a court-supervised “guardianship of the estate”: expensive, slow, and avoidable.
And here’s the part no one expects. To sort it out, your grieving spouse may have to prove to a judge which money was shared and which was yours alone — using records they can’t reach. I’ve seen a surviving spouse ordered to show that deposits into an account were made after the wedding, with no access to the account and no way to get the bank’s history. It is being asked to prove something with the evidence locked away.
An estate plan — really a set of documents working together — prevents all of this. It lets you decide, on purpose, what happens to everything you own, including leaving all of it to your spouse if that’s your wish.
So — one joint trust?
Sometimes it’s exactly right, when everything going in truly belongs to both of you. Sometimes it’s a quiet mistake you won’t discover until it’s too late to fix. The only way to know is to have someone look at your actual situation before you sign, not after. That’s what estate planning is for — and I’d be happy to help.
