In our July edition, we explored how Law No. 20,021 revolutionized lifetime donations, eliminating the historic risks that used to paralyze these transactions. Today we complete the picture: beyond donating, there are three fundamental instruments for professionally organizing the destiny of your estate: the modernized will, the testamentary trust and patrimonial companies. Each responds to different needs, and choosing correctly among them can mean the difference between a conflictive, costly succession and an orderly, efficient transfer.
The will: the reformulated cornerstone. The Uruguayan Civil Code provides for two written testamentary forms with distinct legal implications. The open will (testamento abierto) is executed before a notary with three witnesses (Art. 793 CC), offering maximum legal certainty at the cost of confidentiality. Its strength lies in the evidentiary difficulty of challenging it: notarial public faith and the presence of witnesses create a nearly unassailable presumption of validity. The closed will (testamento cerrado, Art. 801 CC) preserves secrecy through a sealed document that the testator presents before a notary and five witnesses, declaring that it contains their wishes. Here a legal paradox arises: greater privacy means greater vulnerability, and national case law shows higher rates of nullity due to formal defects. Finally, the will executed by public act abroad (Art. 828 CC) is valid in Uruguay if it complies with the formalities of the place where it was executed and conforms to the public policy of the Uruguayan Civil Code, allowing Uruguayans with international estates to structure their assets from abroad, subject to the territorial limits on the disposition of real property. However, a will does not avoid the Uruguayan probate process, which remains slow and costly.
Testamentary trust. Law No. 17,703 introduced a revolutionary figure: the testamentary trust, which is created by will but acquires independent legal life upon the death of the settlor; title to the assets transfers to the trustee upon the testator's death. It allows for arrangements impossible under a pure will: multigenerational administration with successive beneficiaries, clauses protecting against the heirs' creditors, and professional management by trustees regulated by the Central Bank of Uruguay (BCU). However, it cannot affect the heirs' forced share (legítima) or other compulsory allocations. On the tax side, during the settlor's lifetime there is no taxable event; post-mortem, income is taxed in the hands of the beneficiaries. Guarantee trusts enjoy full exemption from the Real Estate Transfer Tax (Impuesto a las Transmisiones Patrimoniales, ITP), an advantage that is preserved in the testamentary form. Even when, upon the settlor's death, real property is transferred to the heir by way of succession, no ITP applies, because what is transferred is the settlor's status, not the property itself.
Patrimonial companies: a necessary mention. SAS companies with endorsable registered shares allow real estate wealth to be transferred through the sale of the share package, avoiding the probate process. Combined with free-trade-zone status, they achieve tax neutrality for non-Uruguayan-source income. This is the third leg of the tripod, especially relevant for investment properties.
Strategic planning: the art of combining tools. Excellence lies not in choosing one instrument but in articulating them synergistically: an open will for personal property and specific bequests, a testamentary trust for productive assets that require professional administration, and patrimonial companies for income-producing real estate. At MECOL ESTUDIO we design succession structures that go beyond the mere transfer of wealth, combining technical rigor with strategic vision. Because true estate planning is not just about transferring assets: it is about perpetuating family wealth with intelligence and regulatory precision.
