When an Elderly Relative Has Dementia or Severe Disability, Can Family Members Directly Sign Contracts or Access Deposits? A Look at Guardianship Declaration, Assistance Declaration, and Voluntary Guardianship

When an elderly relative is unable to manage their own affairs due to dementia or severe disability, a spouse or child does not automatically obtain legal representation rights—without a court's guardianship declaration or a pre-arranged voluntary guardianship, family members signing nursing home contracts or accessing deposits are legally considered 'unauthorized agency,' with uncertain validity. Guardianship declaration (for those without capacity) and assistance declaration (for those with significantly reduced but partial capacity) are two different levels of declarations, with different applicable situations, applicant qualifications, and guardian authorities. Alternatively, while the person still has capacity, a 'voluntary guardianship' can be used to pre-designate a trusted person. The following organizes legal bases, application procedures, and property protection mechanisms, providing neutral legal information, not case-specific legal advice.

Guardianship Declaration vs. Assistance Declaration: What's the Difference?

Both are court declarations regarding limited capacity, but the thresholds and effects differ:

Guardianship declaration (Articles 14 and 15 of the Civil Code): Applies to persons who, due to mental impairment or other mental deficiency, are unable to express or receive intent, or to understand the effect of expression of intent. After declaration, they become 'persons without capacity,' and legal acts are performed by the guardian.
Assistance declaration (Article 15-1 of the Civil Code): Applies to persons whose capacity is 'significantly insufficient' but not to the extent of guardianship declaration. The person retains general capacity, but specific major acts (Article 15-2 of the Civil Code) such as engaging in business, consumer loans, consumer deposits, acting as a guarantor, gifts, trusts, litigation, mediation, arbitration, disposal of important property like real estate and cars, estate division and inheritance require the assistant's consent.
The qualifications for applicants are the same: the person themselves, spouse, relatives within the fourth degree of kinship, other relatives who have lived with the person for the past year, prosecutors, municipal/county authorities, social welfare institutions, the assistant, or the voluntary guardian can apply to the court (Article 14 of the Civil Code).

Can Family Members Directly Sign Nursing Home Contracts or Access Deposits for an Elderly Relative with Dementia?

This is the first hurdle for most families—the answer is: without legal authorization, no.

Taiwan law does not have an automatic general agency system where 'spouses or children can make decisions by default.' Only a court-appointed guardian (Article 1098 of the Civil Code: the guardian is the legal representative of the ward within the scope of guardianship) or a valid voluntary guardian has the legal authority to sign contracts and manage property.
Contracts signed without authorization are legally 'unauthorized agency,' with uncertain validity, requiring ratification by the elderly person (if still capable) or by a subsequent authorized person to take effect—in practice, disputes have arisen such as banks refusing to disburse funds or siblings objecting to decisions made by one family member.
If the elderly person's condition has not reached the point of being 'unable to express intent' but only has weaker judgment or mobility, a guardianship declaration may not be necessary. First, assess the elderly person's cognitive and self-care status (refer to this site's 'Early Signs of Dementia' page), and consider a less restrictive assistance declaration if needed. Not every case requires a guardianship declaration.

Voluntary Guardianship: Choose Your Guardian While You Still Can

The voluntary guardianship system added in 2019 (Articles 1113-2 to 1113-10 of the Civil Code) allows persons with capacity to 'plan ahead':

The person can agree with one or more persons on who will serve as guardian if a guardianship declaration is later made. The contract must be notarized with both parties present, and the notary must notify the court in the person's domicile within seven days (Article 1113-3 of the Civil Code).
The contract does not take effect immediately but only when the person is actually declared under guardianship by the court.
The court generally respects the person's chosen candidate unless there is concrete evidence that the candidate would be detrimental to the person's interests, in which case the court may select another (Article 1113-4 of the Civil Code)—suitable for retirement planning or elderly property arrangements to reduce future disputes among family members over the choice of guardian.

How to Apply? Is an Assessment Required? What Are the Costs?

Both guardianship and assistance declarations are applied to the court, not self-determined:

Apply to the family court of the district court in the elderly person's domicile or residence (Article 164 of the Family Act; assistance declaration applies mutatis mutandis).
The court generally commissions a psychiatrist or professional institution for assessment to determine the person's mental state and capacity level, unless the evidence is already clear (e.g., long-term coma, vegetative state) (Article 167 of the Family Act).
The application fee for non-contentious matters is currently NT$1,500 (subject to the latest announcement by the Judicial Yuan). Assessment fees are additional and vary by the commissioned hospital or institution, with no standardized amount. The entire process, including assessment, typically takes several months in practice, depending on case complexity and court schedule.

Guardian's Responsibilities and Property Protection Mechanisms for the Elderly

A guardianship declaration does not mean 'family members have full authority.' The court continuously supervises the guardian:

Within two months of appointment, the guardian must, together with a person designated or approved by the court, prepare a property inventory of the ward and submit it to the court (Article 1099 of the Civil Code). The court may at any time require the guardian to report on the ward's property status.
The guardian's disposal of the ward's real estate, or leasing or terminating the lease of the ward's residential building, requires court approval. Investments made with the ward's property are limited to government bonds, treasury bills, central bank savings certificates, etc.; stocks or funds are not allowed (Article 1101 of the Civil Code).
This court supervision mechanism is key to protecting the elderly person's property and preventing misuse or fraud by relatives. If you suspect the elderly person has suffered property embezzlement, fraud, or abuse, you can call the 113 protection hotline, or consult the Family Affairs Service Center of the court or the Legal Aid Foundation.

FAQ

What is the difference between guardianship declaration and assistance declaration?

The main difference lies in the degree of limitation on capacity. Guardianship declaration (Articles 14 and 15 of the Civil Code) applies to persons who are 'unable to express intent or understand the effect of expression of intent.' After the declaration, they become persons without capacity, and legal acts are performed by the guardian on their behalf. Assistance declaration (Article 15-1 of the Civil Code) applies to persons whose capacity is 'significantly insufficient' but not to the extent of guardianship declaration. The person retains general capacity, but specific major acts (Article 15-2 of the Civil Code) such as engaging in business, acting as a guarantor, disposing of real estate, or inheritance require the assistant's consent. The qualifications for applicants are the same for both; the court determines which applies based on assessment results.

If parents have dementia, can children directly sign a nursing home admission contract on their behalf?

No. Taiwan law does not grant automatic agency rights to spouses or children based solely on relationship. Only a court-appointed guardian or a valid voluntary guardian has the legal authority to sign contracts on behalf of the person. Signing without authorization is legally 'unauthorized agency,' with uncertain validity, requiring ratification by the elderly person (if still capable) or by a subsequent authorized person. If the elderly person still retains some cognitive and functional capacity, a less restrictive assistance declaration may be considered instead of a guardianship declaration.

After a guardianship declaration is finalized, can family members directly withdraw money or handle accounts at the bank for the elderly person?

Only the court-appointed guardian can manage the ward's property as a legal representative (Article 1098 of the Civil Code). General family members cannot access the elderly person's deposits at the bank based solely on kinship. The guardian is not free to use the property arbitrarily: within two months of appointment, the guardian must submit a property inventory to the court (Article 1099 of the Civil Code). Disposal of real estate or investments is subject to restrictions (Article 1101 of the Civil Code; investments are limited to government bonds, treasury bills, central bank savings certificates, etc.). The court may at any time require the guardian to report on the property status.

How much does it cost and how long does it take to apply for a guardianship or assistance declaration?

The application is a non-contentious matter; the current court fee is NT$1,500 (subject to the latest announcement by the Judicial Yuan). The court usually commissions a psychiatric or professional institution for assessment, with assessment fees varying by institution and not standardized. The entire process, including assessment, typically takes several months in practice, depending on case complexity and court schedule. There is no legally fixed duration. For exact costs and timelines, consult the accepting court or the Family Affairs Service Center.

What is voluntary guardianship? Why should retirees plan for this in advance?

Voluntary guardianship (Articles 1113-2 to 1113-10 of the Civil Code, added in 2019) allows a person with capacity to pre-agree with a trusted person on who will serve as guardian if a guardianship declaration is later made. The agreement must be notarized with both parties present and takes effect only upon the guardianship declaration. The court generally respects the person's chosen candidate unless there is concrete evidence that it is not in the person's best interest. It is suitable for retirement planning or elderly property arrangements to avoid future disputes among family members over the choice of guardian.

What should I do if I suspect a family member is using guardianship or financial management to embezzle the elderly person's property?

The guardian is under continuous court supervision: property inventory, disposal of real estate, and investments are subject to legal restrictions and reporting obligations (Articles 1099 and 1101 of the Civil Code). The court may at any time require reports and inspections. If you suspect the elderly person has suffered property embezzlement, fraud, or abuse, you can call the 113 protection hotline, or consult the Family Affairs Service Center of the court in the elderly person's domicile, or the Legal Aid Foundation. If necessary, you can petition the court to replace the guardian or raise objections.
