What is a trust
Inter vivos vs. testamentary
Florida Trust Code highlights
| Provision | Florida statute | Key rule | Practice note |
|---|---|---|---|
| Rule Against Perpetuities | §689.225 | 1,000 years for trusts created after July 1, 2022 | Effectively a dynasty trust jurisdiction — plan multigenerational GST trusts accordingly |
| Trust execution formalities | §736.0403(2) | Two witnesses; notarization not required for validity but essential if real property involved | Execute with same formalities as a will to avoid trust being challenged as testamentary instrument |
| Will execution formalities | §732.502 | Two witnesses who sign in presence of testator; notarization optional (self-proved will) | Pour-over will must meet these requirements; execute contemporaneously with trust if possible |
| Elective share / elective estate | §732.2035 | Surviving spouse entitled to 30% of "elective estate" including certain trust assets | Revocable living trusts are included in elective estate — inter vivos trusts do not fully shelter assets from spousal rights in FL |
| Spendthrift exceptions | §736.0503 | Unenforceable against: (1) child/spouse/former spouse with judgment for support; (2) creditor for beneficiary protection services; (3) state/federal claim | Spendthrift clause does not protect against child support or alimony obligations |
| Trustee loan powers | §736.0816(6) | Trustee may borrow money and mortgage/pledge trust property for any duration | Confirm power exists in trust instrument before pledging trust assets as collateral |
| Loans to beneficiary | §736.0816(19) | Trustee has lien on future distributions for repayment of loans to beneficiary | Document all loans with promissory note; monitor payment; enforce if delinquent |
| Incapacity standard | Trust instrument | Typically: certification by physician that settlor cannot handle financial affairs — lower standard than testamentary capacity | Drafting issue: specify independent physician certification to prevent family disputes over incapacity trigger |
Domestic Asset Protection Trust (DAPT) jurisdiction comparison
| Jurisdiction | Creditor limitation period | Exception creditors | State income tax | Directed trust statute | CGT assessment |
|---|---|---|---|---|---|
| South Dakota | 2 years (shortest) | Child support; alimony; fraudulent transfer | None | Yes — strong bifurcation | Top tier — preferred for most UHNW clients |
| Nevada | 2 years | Child support; existing tort claims; fraudulent transfer | None | Yes | Top tier — competitive with SD |
| Delaware | 4 years | Child support; alimony; fraudulent transfer | None (for non-residents) | Yes | Strong — longer seasoning period than SD/NV |
| Wyoming | 4 years | Child support; fraudulent transfer | None | Yes | Competitive but less established case law |
