exposure but is subject to stamp duty, with some exemptions. • Private foundations or dedicated vehicles: estab - lishing a private foundation or similar structure is often used to ensure the integrity of an art col - lection, particularly for cultural or philanthropic purposes. • Sales or transfers with retained usufruct: this mechanism allows the owner to transfer ownership while retaining usage rights for life, which can be a way to manage succession gradually. Where the estate concerns the body of work of a deceased artist, additional planning is often essential to: • centralise management and decision-making pow - ers; • reserve the integrity, coherence and market value of the collection; • avoid fragmentation among multiple heirs; and • ensure predictable governance and reduce the risk of intra-family disputes. From a tax perspective, planning may also take into account cultural patronage incentives available under the Tax Benefits Statute ( Estatuto dos Benefícios Fis- cais ) where institutionalisation or structured donation is contemplated. Early structuring is typically decisive in preventing post-mortem conflicts, forced disposals and ineffi - cient tax outcomes. 10.2 Legal and Fiscal Issues in Artwork Succession Several legal and tax issues can arise when artworks are inherited, particularly when no planning exists. Legal – Intestate Succession Under Portuguese law, heirs are determined according to a predefined order (spouse, descendants, ascend - ants and other relatives). Artwork is included as part of the estate and distributed accordingly. Two-thirds of the total estate must be allocated to the legitimate heirs. In practice, succession frequently results in:

• undivided estates or co-ownership, which may complicate the management, loan, sale or export of artworks; • conflicts between heirs regarding conservation, exhibition or disposal; • liquidity constraints, particularly where conserva - tion, insurance, storage or restoration costs arise but the estate lacks sufficient cash assets; and • valuation uncertainty, especially for unique or illiquid works, potentially affecting both distribution and taxation. Where artworks are classified or subject to cultural protection regimes, additional constraints may apply, including limitations on export and statutory pre-emp - tion rights of the state. Succession may also expose latent title defects, including disputed ownership, stolen artworks or works with problematic provenance. Heirs may face restitution claims, civil litigation or reputational risks, particularly in cross-border contexts. Digital art and blockchain-based assets (including NFTs) also form part of the estate. Their succession may raise additional practical challenges, including access to private keys or digital wallets, valuation at the date of death and identification of the governing law where tokens are traded on decentralised plat - forms. Tax – Stamp Duty Inheritance is exempt from stamp duty when the heir is a spouse, descendant or ascendant. In all other cases, 10% stamp duty applies, generally calculated based on the appraised value of the artwork at the time of death. Accurate valuation and supporting documentation are therefore critical, particularly for unique, illiquid or highly volatile assets, including digital works. 10.3 Tax Implications of Artwork Gifts and Donations The tax implications for acquiring artworks through gifts and donations are as follows:
