# The SLAT Trap: When the Estate Plan Meets the Divorce

- Description: Spousal Lifetime Access Trusts move wealth out of the taxable estate — with the marriage as the access mechanism. In a divorce, the donor loses the access, sometimes keeps the tax bill, and the trust may be beyond the court's reach.

Over the last decade, wealthy married couples have funded Spousal Lifetime Access Trusts by the thousands — irrevocable trusts set up by one spouse for the benefit of the other, moving assets and their future growth out of the donor's taxable estate while keeping indirect access through distributions to the beneficiary spouse.

As an estate-tax strategy, it works. As a marriage-contingent structure, it has a failure mode nobody enjoys discussing at signing: the marriage is the mechanism. End the marriage, and the donor spouse's access ends with it.

## What breaks in a divorce

**The access is gone, and the assets are not coming back.** The trust is irrevocable. The donor cannot reclaim the assets or rewrite the terms. Unless the document contains "current spouse" or divorce cut-off language, the now-ex beneficiary spouse may simply remain a beneficiary of a trust funded with what used to be the donor's wealth.

**The property analysis turns strange.** Assets that were plainly marital or separate before the transfer may no longer be "property" the divorce court can divide at all — even though they remain economically enormous. Whether the beneficiary spouse's interest counts as a divisible property interest depends on state law and the trust's terms, and the answer reshapes the entire settlement map.

**The tax trap keeps running after the decree.** Most SLATs are grantor trusts — the donor pays the income tax on trust earnings, a feature while married. Under the spousal unity rule of IRC § 672(e), grantor-trust status is measured when the interest was created — meaning the trust can remain a grantor trust *after* divorce. The provision that once softened this, IRC § 682, was repealed by the 2017 tax act for instruments executed in 2019 or later. The result: a donor spouse can end up paying the income taxes on a trust whose distributions now benefit only their former spouse.

The SLAT before and after divorce: access ends, the property analysis turns strange, and the tax bill may stay.

## If you have a SLAT and a divorce is possible

The trust instrument is the first document I want to read — before the financial statements. What matters: whether the beneficiary is defined as "my spouse" or by name; whether divorce terminates the interest; who the trustee is and how removable; whether grantor-trust status can be turned off; and how distributions have actually been administered, because sloppy administration creates its own estate-tax exposure.

Then the SLAT has to be placed inside the settlement arithmetic. A trust that cannot be divided can still be counted — through offsets, through maintenance, through the economic reality of who will enjoy what. And the ongoing tax burden of grantor-trust status is itself a negotiable item with real present value.

## If you are planning one now

Draft for the marriage you hope for and the divorce you might get: a floating-spouse definition or divorce cut-off, a mechanism to toggle off grantor-trust status, and — where the amounts justify it — a marital agreement that says in advance how the SLAT will be treated. This is exactly the coordination gap I wrote about in [The Prenup and the Trust](https://blog.denverdivorce.com/prenuptial-agreement-estate-plan-coordination-colorado/): the estate plan and the marital agreement have to be drafted by people who are talking to each other.
