Wills in Uruguay: what the law imposes on your wishes
A handwritten will valid in your home country generally does not govern Uruguayan assets — and the law reserves half or more of the estate to forced heirs.
Anyone with assets in Uruguay tends to believe a will resolves succession however they wish. It does —within limits Uruguayan law imposes, and which come as a surprise.
There are two points almost no one anticipates. The first: not every will made abroad governs assets located in Uruguay. The second: Uruguayan law reserves a portion of the estate to forced heirs, and that portion can reach three quarters of everything. Freedom to dispose is real, but it is smaller than most imagine.
This article shows what the law allows and what it reserves.
The surprising rule: the foreign holographic will
The holographic will —written in the testator’s own hand— is a valid form in several countries.
In Uruguay there is a key nuance. Under the 1940 Montevideo Treaty, a holographic will executed in Argentina or Paraguay is admitted for assets located in Uruguay. But a holographic will executed elsewhere —say the United States, the United Kingdom, Spain or Italy— is not valid in Uruguay.
The consequence is concrete and expensive: a foreigner who handwrote a will in a country not covered by the treaty, trusting it would govern their Uruguayan assets, may have left those assets effectively without a valid disposition —and subject to Uruguayan legal succession, which may not match their wishes.
To dispose of assets in Uruguay safely, the recommended path is a will executed in the forms local law recognizes, typically before a notary (escribano).
Forced heirship: what you cannot take from forced heirs
The core of Uruguayan succession law is the forced share (legítima) —the portion of the estate the law compulsorily reserves for forced heirs, also called legitimarios.
Forced heirs are descendants (children and, by representation, grandchildren) and, in their absence, ascendants. The surviving spouse or partner has their own protections, among them a real right of use or habitation over the family home.
The reserved portion varies with the number of children, and here freedom shrinks:
- With one child, the forced share is half the estate.
- With two children, it rises to two thirds.
- With three or more children, it reaches three quarters.
What remains after the forced share is the disposable portion —the fraction the testator may dispose of freely, leaving it to whomever they wish: a third party, a friend, an institution, or reinforcing one heir’s share.
A will that invades the forced share is not simply ignored —it may be subject to reduction, collation or challenge by the prejudiced heirs. That is why drafting without calculating the real forced share is preparing a future conflict.
What a will can and cannot do
It can: designate heirs or legatees within the disposable portion; appoint an executor (albacea) to enforce the provisions; anticipate the division among heirs; and make specific bequests of particular assets.
It cannot: deprive forced heirs of the forced share, except in cases of disinheritance for a just and proven cause —an exceptional and strictly regulated situation.
It is also worth distinguishing between legally effective provisions and mere expressions of wish. Not everything written in a will produces an automatic effect; statements of intent without adequate legal form bind no one.
The will is essentially revocable: a person may execute as many as they wish over a lifetime, supplementing or revoking earlier ones. And each will executed in the country is communicated to the Register of Wills —though its content and existence only become known after death.
Responsibility note: the rules on form, capacity and content of the will, as well as the forced-share fractions, arise from the Uruguayan Civil Code and may have particularities depending on family composition. This article describes the general regime; drafting an effective will requires analysis of the concrete case.
Tax: what changes on transfer
A relief and a warning.
The relief: Uruguay has no inheritance tax. The transfer itself is not taxed as it is in other countries.
The warning: where there is real estate, the heirs pay the Property Transfer Tax on the cadastral value of the assets, and Net Wealth Tax may apply depending on the case. The absence of inheritance tax does not mean a transfer without cost.
Moreover, the succession process is judicial: to dispose of real estate, vehicles or funds, you must obtain the declaration of heirs and register it. There is also the possibility of accepting the inheritance under benefit of inventory, which limits the heirs’ liability for debts to the inherited estate.
Where you must think about two countries
The succession of assets located in Uruguay follows Uruguayan law —but anyone arriving rarely has wealth on one side only.
Assets in the country of origin follow their own law and taxation, including any levy on the transfer of wealth. And the interaction between the two succession orders —what is transferred where, under which law, at what cost— is the core of international estate planning.
One practical point deserves emphasis: the form of asset ownership interacts with succession. A property held by an individual and the same property held by a company transfer in different ways —and, in some cases, a wealth structure orders continuity better than a will alone.
The starting point
Making a will in Uruguay is possible and advisable for anyone with assets in the country —but with the correct form and within the limits of the forced share. A will brought from home, handwritten, may be worth nothing here; and a will that ignores the forced share plants a dispute among the heirs.
