While the older person has decision-making capacity, designate a future guardian in writing
While the person can decide for themselves, record who should act as guardian if that changes, with notarization if desired. The source warns that without prior designation, disputes over signing and managing money can require a court's involvement and take longer when relatives disagree.
What it takes
Notarization costs a few hundred RMB in China. One conversation can settle the choice, but discussing a future loss of independence may be difficult.
What you may gain
China's Civil Code allows an adult with full civil capacity to agree in advance with a close relative, another willing individual or an organization on a future guardian and record the choice in writing. That person assumes the role upon full or partial loss of civil capacity. The source emphasizes that without such a document, determining who signs or manages money may require court designation.
Context & considerations
This is an agreed advance guardianship arrangement, giving effect to the person's own choice ahead of the default order. It is especially useful for people living alone, with children elsewhere or complicated family relationships. The author recommends notarization.
