What it means
The first sentence is the whole rule: as between trustee and beneficiaries, the trustee administers the trust solely in the interests of the beneficiaries. A sale, encumbrance, or other transaction involving trust property that serves the trustee's own account — or is otherwise tainted by a conflict between fiduciary and personal interests — is voidable by an affected beneficiary, without proof the trust lost a dollar.
The statute then lists the exits: the trust's terms authorized the deal, a court approved it, the beneficiary consented, ratified, or released it, the claim lapsed under §736.1008, or the contract predates the trusteeship. Transactions with the trustee's spouse, descendants, siblings, parents, or affiliated entities are presumed conflicted, and later subsections regulate proprietary-fund investments, voting stock the trust controls, and a trustee's use of trust money for defense fees.
- Core command: administer solely in the interests of the beneficiaries.
- Self-interested transactions in trust property are voidable by an affected beneficiary — harm to the trust need not be proved.
- Exits: authorization in the trust, court approval, beneficiary consent/ratification/release, expiration of the claim under §736.1008, or a contract made before trusteeship.
- Deals with the trustee's spouse, descendants, siblings, parents, or entities the trustee controls carry a presumed conflict.
- Corporate trustees investing in their own proprietary funds operate under specific authorization and annual-disclosure rules.
- A trustee defending its own conduct must give written notice before paying attorney fees from the trust — and the court can order the money restored with interest.
How it plays out
Loyalty problems in the trusts we see are usually casual rather than corrupt — a trustee who hires his own management company, sells the trust's condo to a daughter, or parks trust cash in his business. The statute makes those transactions voidable whether or not the price was fair, and it presumes a conflict for close relatives. Our standing advice to trustees: get the conflicted deal authorized in advance — by the instrument, by beneficiaries after full disclosure, or by the court — because unwinding it later always costs more than asking first.
