Will Substitute Trust Lawyer | Advisory on structuring, drafting, and defending a will substitute trust
A will substitute trust (유언대용신탁) is a trust arrangement recognized under Article 59 of the Trust Act (신탁법 제59조) where the settlor retains benefits during their lifetime and designates a beneficiary to receive trust property upon the settlor's death, without going through a will's formal execution requirements. It is increasingly used to pre-empt inheritance disputes, protect a surviving spouse's housing, or delay a young heir's control over assets. However, it interacts in complicated ways with forced heirship (유류분), trustee duties, and inheritance tax rules, so poor drafting can trigger the very litigation it was meant to avoid.

Will Substitute Trust | Will, Will Substitute Trust, or Lifetime Gift — Which Fits Your Situation
There is no single correct way to pass on assets. The right tool depends on how much control you want to keep, how contentious your family relationships are, and how liquid your assets are. These three tools are often compared side by side.
| Formal requirements | Strict; must meet one of five statutory forms |
| Revocability | Freely revocable until death |
| Effect on control during life | None — assets stay in your name |
| Vulnerability to disputes | High if form is defective or capacity is contested |
A will only takes legal effect if it strictly satisfies the form requirements set out in Article 1065 of the Civil Code (민법 제1065조); even small defects can void the entire document.
| Formal requirements | Trust agreement with a trustee; more flexible drafting |
| Revocability | Can be made revocable or irrevocable by settlor's choice |
| Effect on control during life | Settlor can remain the primary beneficiary during life |
| Vulnerability to disputes | Lower on execution formality, but still exposed to forced share claims |
Recognized under Article 59 of the Trust Act (신탁법 제59조); trust property passes to the designated beneficiary upon the settlor's death according to the trust terms, not the general succession rules.
| Formal requirements | Gift contract; registration for real property |
| Revocability | Generally irrevocable once completed |
| Effect on control during life | Donor loses control immediately |
| Vulnerability to disputes | Can still be clawed back into forced share calculations |
Gifts made within a certain period before death, or gifts to heirs generally, can be added back when calculating a forced share claim (민법 제1114조, 제1118조).
Will Substitute Trust | How a Will Substitute Trust Actually Works
Before drafting, it helps to understand who the parties are and what happens at each stage — while the settlor is alive, and after death.
The three roles: settlor, trustee, beneficiary
The settlor (usually the asset owner) transfers legal title of specified property to a trustee, who manages it according to the trust agreement for the benefit of a designated beneficiary. Under Article 59 of the Trust Act (신탁법 제59조), the settlor can be named as the primary beneficiary while alive, with a second beneficiary taking over only after the settlor's death.
Revocable vs. irrevocable trusts
A revocable will substitute trust lets the settlor change the beneficiary or terminate the trust later, which offers flexibility but weakens its protection against future disputes among family members. An irrevocable structure locks in the succession plan but requires the settlor to be confident about the arrangement before signing, since later changes may be difficult or impossible.
What can be placed in the trust
Real estate, cash, securities, and business interests can generally be settled into trust, though real estate requires a change of registered ownership to the trustee (부동산등기법 관련 절차), which is often the step families are most hesitant about. Choosing which assets to include, and which to leave outside the trust for liquidity or tax reasons, is itself a key planning decision.
Will Substitute Trust | Forced Heirship Claims Against Trust Property
The single biggest reason a will substitute trust ends up in litigation is a forced share (유류분) claim by an heir who feels shortchanged. This section covers how that risk arises and how it is currently being addressed in practice.
Can trust property be reached by a forced share claim?
Korean courts and commentators have debated whether property placed in a will substitute trust should be treated like a lifetime gift for forced share calculation purposes. If a court treats the trust transfer as equivalent to a disposition that reduced the estate available to statutory heirs, the trust property (or its value) may be included in the base used to calculate a forced share (민법 제1113조, 제1114조).
Timing and intent matter
A trust set up long before death, with a legitimate management purpose beyond simply disinheriting a particular heir, is generally viewed differently from one set up shortly before death that appears designed mainly to defeat a forced share claim. Documenting the settlor's broader estate planning rationale can matter if the arrangement is later challenged.
Structuring around the risk, not ignoring it
Rather than assuming a trust automatically avoids forced share exposure, careful drafting anticipates it — for example by balancing trust distributions with other lifetime arrangements for heirs who would otherwise have a forced share claim, or by keeping records that support the trust's independent management purpose.
⚠ Forced share claims must be filed within a limited period
A forced share claim generally must be exercised within one year of the claimant learning of the infringement of their forced share, and in any case within ten years of the inheritance opening (민법 제1117조). Trust beneficiaries and trustees should be aware this clock exists on the other side too.
Will Substitute Trust | Trustee Selection and Duties During the Trust's Life
A will substitute trust is not a one-time signing event — it creates an ongoing legal relationship that needs active administration until the beneficiary transition occurs.
Choosing a trustee: family member vs. financial institution
A family member trustee may better understand the settlor's wishes but can face conflicts of interest, especially if they are also a beneficiary or an heir with competing claims. A financial institution trustee (bank or trust company) tends to offer more neutral administration and better recordkeeping, at the cost of trustee fees.
Fiduciary duties and reporting obligations
Trustees owe a duty of loyalty and a duty of care to the beneficiaries and must manage trust property separately from their own assets (신탁법 제32조, 제37조). Beneficiaries can request accounting and information about trust administration, which becomes important if disputes arise later about how property was managed.
What happens to the trust if the trustee changes or the settlor becomes incapacitated
Trust agreements should specify a succession mechanism for the trustee role and address what happens if the settlor loses capacity before death, since a poorly drafted trust can leave a gap in management authority at exactly the moment it is most needed.
Will Substitute Trust | Inheritance Tax and Gift Tax Considerations
A will substitute trust does not avoid inheritance tax; the tax authorities generally still treat the transfer to the beneficiary upon the settlor's death as part of the taxable estate.
When is trust property taxed as inheritance
Property that passes to a beneficiary upon the settlor's death under a will substitute trust is generally included in the taxable estate for inheritance tax purposes under the Inheritance Tax and Gift Tax Act (상속세 및 증여세법 관련 규정), since economically it functions like a bequest even though it bypasses the probate-style formalities of a will.
Distinguishing lifetime benefit from death benefit
If the settlor names themselves as the lifetime beneficiary and only designates a successor beneficiary to take effect at death, the timing of when value actually transfers to that successor is central to determining when and how tax applies. This is an area where tax counsel and trust drafting need to be coordinated rather than treated separately.
Will Substitute Trust | From Initial Consultation to a Signed Trust Agreement
The lawyer reviews the client's assets, family structure, and what outcome they are trying to achieve — protecting a spouse, delaying a young heir's control, or simply avoiding a contested will.
Before drafting, the lawyer maps which heirs could bring a forced share claim and estimates how the proposed trust structure interacts with inheritance tax rules.
The lawyer drafts trust terms covering beneficiary designation, revocability, trustee powers and reporting duties, and, where a financial institution will serve as trustee, coordinates the agreement with that institution's standard trust terms.
The client executes the trust agreement and completes any required title transfers to the trustee, such as real estate registration changes.
For revocable trusts, the lawyer can assist with later amendments as family circumstances change, and can advise the trustee or beneficiaries if a dispute arises during administration.
Will Substitute Trust | How Fees Are Generally Calculated
Typically calculated based on the complexity of the family situation and the number and type of assets to be settled into trust, rather than a flat rate, since a single-asset trust and a multi-generational plan with several heirs require very different amounts of drafting work.
If a bank or trust company will serve as trustee, additional time may be required to align the lawyer-drafted terms with the institution's internal trust templates; this is usually billed separately from the core drafting fee.
Where real property is settled into the trust, registration tax, acquisition tax considerations, and registration service fees are separate from legal fees and depend on the property's value.
Some clients retain the firm for periodic review of the trust as family circumstances or tax law change, billed as a separate ongoing arrangement rather than a one-time fee.
If a forced share claim or trustee dispute later develops into litigation, that is billed separately from the original advisory and drafting engagement, generally following standard litigation fee structures.
