Spousal Lifetime Access Trust
Simple explanation
A SLAT is an irrevocable lifetime gift trust created by one spouse for the other spouse and often descendants, seeking to move assets outside the donor's estate while preserving indirect family access through discretionary distributions.
- The donor keeps no enforceable right
- The donor should not retain an enforceable right to trust property.
- Divorce, death or creditors can end practical access
- Divorce, death of the beneficiary spouse, and creditor events can end practical access.
- Mirror-image trusts risk the reciprocal-trust rule
- Near-mirror SLATs created by both spouses can trigger reciprocal-trust concerns.
Who does what in a trust
- Grantor / settlor Creates the trust and contributes property under the governing terms.
- Trust Holds legal title and defines powers, standards, beneficiaries, and duration.
- Trustee Administers, invests, accounts, and distributes under the document and governing law.
- Beneficiaries Receive permitted benefits now or later under the distribution terms.

Questions about Spousal Lifetime Access Trust
What determines how this trust works?
The signed governing terms, valid funding, retained powers, trustee authority, beneficiary rights, administration, tax classification, timing, and applicable state and federal law—not the trust name by itself.
Does this kind of trust automatically reduce tax or protect assets?
No automatic result follows from the label. Income, gift, estate, and GST tax classifications are separate questions, and creditor treatment depends on the settlor's and beneficiaries' rights, governing law, timing, and administration.
What should be verified before creating or funding the trust?
Verify the objective, governing instrument, fiduciaries, beneficiary standards, title and transfer restrictions, valuation, tax reporting, liquidity, governing state, expected administration, costs, and advice from appropriately qualified professionals.
