The Era of Free Asset Allocation Arrives: Analyzing Taiwan’s Legal Reform Abolishing Forced Heirship for Siblings

Taiwan's inheritance system has undergone its most significant transformation in recent years. In late July 2026, the Legislative Yuan officially passed the third reading of amendments to the Civil Code, removing the "compulsory portion (forced heirship) for siblings" from the law. This reform reverses the traditional legal framework that previously overemphasized "bloodline family co-ownership," handing full autonomy over estate disposition back to property owners and marking a major victory for individual free will in inheritance law.

Breaking Free from Bloodline Constraints and Restoring Asset Autonomy

In the past, to safeguard the livelihoods of a deceased person's family members, the Civil Code included mandatory "compulsory portion" provisions. Even if a decedent executed a will explicitly stating a wish to exclude a specific sibling, that sibling could still legally claim one-third of their statutory share.

However, amidst drastic changes in societal structure, many siblings have long been estranged or even alienated. The old system frequently led to the absurd situation where siblings who offered no care or support during the decedent's lifetime could still legally claim a piece of the pie after death, sparking countless inheritance disputes. Removing the compulsory portion for siblings frees property owners from bloodline constraints when distributing their hard-earned savings, allowing them to transfer their life's work to actual caregivers or donate it to charitable causes.

Enhanced Rights for Childless Couples and Singles

This wave of inheritance reform deeply impacts modern society's unmarried singles and DINKs (Double Income, No Kids):

• DINK Couples (Childless Spouses):

  Under the old system, if one spouse passed away and both parents had already deceased, the surviving spouse had to divide the estate with the deceased's siblings. Even with a valid will, siblings could still demand their compulsory portion, often resulting in joint property ownership of the marital home. Under the new framework, as long as a valid will is executed in advance, the surviving spouse can inherit 100% of all real estate and financial assets.

  
  

• Unmarried Singles:

  For singles without children, bequeathing assets to a cohabiting partner, close friend, or charity was previously shadowed by the threat of siblings contesting the estate. Following the implementation of the new law, singles gain ultimate control over their personal property.

Siblings Still Retain Inheritance Rights Without a Will

Many people mistakenly assume that "abolishing the compulsory portion" means "siblings lose all inheritance rights," which is a major legal misconception.

This legal amendment only removes the "guaranteed minimum share (compulsory portion)" in Article 1223; it does not revoke siblings' status as "third-order statutory heirs" under Article 1138. This means that if a decedent leaves no valid will and has no first-order (children) or second-order (parents) heirs, the estate will still be distributed among siblings according to statutory proportions. Therefore, executing a legal will in advance has become an indispensable legal step to carry out one's personal asset allocation wishes.

Early Planning Is Essential to Realize Your Intentions

With the amended provisions taking official effect following a 6-month grace period after promulgation, Taiwanese society formally enters a new era governed by individual wills. While regulatory relaxation offers greater freedom, it also implies that individuals must take on greater responsibility for estate planning. Whether choosing a holographic, dictated, or notarized will, ensuring that the document satisfies legal requirements and properly designates an "executor of the will" is essential to guaranteeing that one's post-mortem wishes are smoothly executed, achieving true peace of mind in wealth succession.
