「福祉型信託」(Welfare Trusts)為家族治理(Family Governance)、家族事業所有權(Family Property Business Ownership)、家族財產事業經營管理(Family Property Business Management)所組成之「家族信託」(Family Trust)核心,具有民事信託與商業信託之雙面性,且非僅僅為單純之財產管理制度,而係「財產管理運用、活用以及傳承」機能之最大程度展現,以完整支援信託利益享有者包括生活及財產管理全盤支援架構建立之身心照護。有鑑於此,本文以我國信託法主要繼受之日本「信託法」法制規範及其相關學理與實務發展為比較法對象,以福祉型信託為核心,對家族信託與遺囑信託進行研究。首先,家族信託制度之建置上,須考量其與消費者權益調和、裁量信託使用界線與合理分配、共益定性、第三人介入之限制、責任信託之搭配。其次,針對永續傳承、連續受益人、特留分、目的信託與特定目的信託、「閉鎖性公司+自益信託」架構等家族信託爭議問題,提出研究對策。再者,家族信託法制尚未完整建立前,應以前述福祉型信託為核心之家族信託為基礎,對信託行為與方法解釋與修正、受益人權益確保、遺囑信託受託催告、法院選任遺囑信託受託人、遺囑信託委託人之繼承人、替代遺囑信託等議題進行解析,俾使我國遺囑信託功能確實發揮與家族信託內涵相互搭配。最後,從家族信託架構下之委託人與受託人角色與功能,提出本文之結論與建議。<br />&ldquo;Welfare trust&rdquo;is the core of a family trust composed of family governance, family property business ownership, and family property business management. It has duality of civil trust and commercial trust in that it is not only a pure property management system, but also the maximum demonstration of the function of property management application, utilization, and inheritance to support the physical and mental care of the trust beneficiaries which include the establishment of a comprehensive support structure for life and a thorough property management. In the establishment of the family trust system, this article firstly argues that it is necessary to consider the coordination with consumer rights, discretionary trust boundaries and reasonable distribution, common benefits, restrictions on third party intervention, and liability trust. Secondly, this article puts forward the research results on the controversial issues of family trust such as perpetual inheritance, continuous beneficiaries, legally reserved portion, purpose trusts and special purpose trusts, and&ldquo;closed company with self-benefit trust&rdquo;structure. Furthermore, before the establishment of a complete family trust legal structure, it is important to analyze the combination of testamentary trust and family trust, interpretation and amendment of trust behaviors and methods to ensure the rights and interests of the beneficiaries, and the appointment the trustee of the testamentary trust by the court, the successor of the settlor of the testamentary trust, and alternative testamentary trust (trust with successive beneficiaries). Finally, the article provides conclusions and suggestions from the perspective of the settlor and the trustee of trust.<br />
