[Civil Documents] Power of Attorney and Seal Certificates for Family Living Abroad — A Certificate of Personal Signature Cannot Be Issued to a Proxy

October 7, 2026황윤상 행정사AI

Summary in 3 lines

  • Some documents for a person living abroad cannot be issued to family members in Korea. A Certificate of Personal Signature (본인서명사실확인서) is issued only to the person in person, and a Certificate of Personal Seal Impression (인감증명서) can be issued to a proxy only with a power of attorney confirmed at a Korean diplomatic mission abroad.
  • Order of submission: check the required documents in the public notice → the person abroad has the power of attorney and consent form confirmed at the Korean mission → the proxy in Korea obtains the seal certificate → submit the application → supplement originals.
  • Deadline: support programs follow the closing date in the public notice. International mail takes about 2 weeks, so book the mission appointment 3–4 weeks before the deadline.

Why did the same consent form come back from the county office twice? The form was correct, it was signed, and every applicant field was filled in.

I am an administrative agent (haengjeongsa) with an office in Songdo, Yeonsu-gu, Incheon. Here is one episode from my work. Preparing documents for administrative agencies and submitting them on a client’s behalf is a basic duty of an administrative agent under Article 2 of the Administrative Agents Act. Inquiries have recently increased about one situation in particular: a family member living abroad who must submit documents to a Korean government office. The documents themselves are not difficult. The hard part is who signs and certifies them, where, and in what way.

That was the case with this consent form. Its content was fine. The reason it came back was the certificate that should have been attached to it.

2. An empty house on Ganghwa Island and a sister in Ho Chi Minh City

The client was a man in his early thirties living in Namdong-gu, Incheon. He worked for a logistics company and visited his late grandmother’s house on Ganghwa Island most weekends. After his grandmother died, his father inherited the house; when his father died three years ago, the client and his older sister inherited the house and land in equal shares. The inheritance registration had already been completed.

The house had stood empty for more than 10 years. The slate roof was cracked, and every rainy season soil washed down toward the neighbor’s wall. Neighbors filed several complaints, and the county office advised him to apply for its empty-house clean-up (demolition) support program. The program would cover a large part of the demolition cost. Without it, demolition would have taken a large share of the wedding savings he had put aside for almost a year.

The problem was his sister. She worked as an expatriate employee at the local subsidiary of a Korean company in Ho Chi Minh City, Vietnam, and her next trip home was planned for the Lunar New Year holiday. The application deadline was the end of October.

The client first tried to handle it alone. He emailed the county form to his sister, and she sent back a scanned copy of the signed consent form. He took the printout to the county office.

3. A Certificate of Personal Signature cannot be issued to a proxy

The county officer’s answer was simple. According to the public notice, the program required original consent forms from all building owners and each owner’s own Certificate of Personal Seal Impression or Certificate of Personal Signature. A printed scan was not an original, and the certificate was missing.

The next day the client went to the community service center to obtain his sister’s Certificate of Personal Signature, assuming that family could do it. But a Certificate of Personal Signature is issued only when the person appears in person; it cannot be issued to a proxy at all. A seal certificate can be issued to a proxy, but only with a power of attorney written by the person, and if that person is abroad, the power of attorney must be confirmed at a Korean diplomatic mission.

On his second visit he brought the original consent form his sister had sent by international mail. This time it was an original, but the certificate was still missing, and the form came back again.

He booked a consultation with our office that Friday. He had emailed the public notice and photos of the returned form in advance, so we could see roughly what was missing before we met. There were 23 days left until the deadline.

4. Getting a seal certificate with a power of attorney confirmed at the consulate

First we decided how to obtain the documents. There were two ways that did not require his sister to fly home.

  1. Have a power of attorney for issuing a seal certificate confirmed at the Korean mission, send it to Korea, and have the client obtain his sister’s seal certificate as her proxy
  2. Have the consent form itself confirmed (notarized) at the Korean mission and send it

The second option looked simpler, but the public notice did not say that a consent form confirmed by a mission would be accepted in place of a seal certificate. When we asked the officer by phone, the answer was “it will probably be fine.” With a deadline at stake, “probably” was not enough. So we made the first option the main plan and asked the county office for a written answer on the second. We sent a written inquiry asking whether a consent form confirmed by a Korean mission abroad could replace the attached seal certificate. We asked in writing because a written answer can be relied on if the officer changes or the reception desk says something different.

We sent his sister a one-page list of what to do:

  • Book a visit to the Consulate General in Ho Chi Minh City (online booking, bring her passport)
  • Write a power of attorney for issuing a seal certificate and have it confirmed by the consul, stating the proxy’s (the client’s) name and resident registration number and the purpose of the certificate accurately
  • On the same day, also have the consent form confirmed by the consul (as a backup, depending on the county’s answer)
  • Send both documents to the client’s address by international express mail

We checked one more thing. His sister had registered her personal seal in Korea before leaving. If she had not, she would first have had to register her seal through the mission, which would have taken longer. With documents for people living abroad, the first question to ask is whether they have a personal seal registered in Korea.

She visited the consulate on Tuesday morning, the earliest available slot, and the documents arrived that Friday. The following Monday the client obtained his sister’s seal certificate at the community service center.

5. When the building register did not match the actual buildings

While the signature issue was being resolved, another problem came up. The application had a field for the floor area of the building to be demolished. The building register listed only one house of 52㎡. But the site photos the client sent showed a separate concrete-block storage shed and an outdoor toilet next to the house.

The client intended to ask for the shed to be demolished too. Written that way, the area in the application would not match the register, and a request for supplementation was likely. The public notice alone did not say whether ancillary structures missing from the register could be included in the support.

We entered only the 52㎡ house in the application, as on the register. On an attached sheet, we included 6 site photos and a site layout sketch, stated that the unregistered shed and toilet stood on the same lot, and asked the county to review whether they could be included. When the agency receives the information it needs up front, the application itself is not shaken even if something different comes up during the site inspection.

Around that time the client stopped by the office with a bag of persimmons from the tree in his grandmother’s yard. They were not quite ripe, so he suggested leaving them on the windowsill for about a week. A week later they were quite sweet.

6. Filing before the deadline and replacing an outdated document

The county’s written answer arrived 9 days before the deadline: a consent form confirmed by a Korean mission would also be accepted. Since we already had the seal certificate, we decided to submit both. Having an extra document is better than missing one.

The submission was organized as follows.

CategoryDocumentsNotes
Applicant (client)Support program application, consent form, seal certificate, copy of IDIssued in Korea
Co-owner (sister)Original consent form (consul-confirmed), seal certificate (issued to proxy)Copy of the consulate-confirmed power of attorney attached
Building documentsBuilding register, land register, certificate of registered mattersCheck issue dates
Attached sheet6 site photos, site layout sketch, request to review ancillary structuresShed and toilet not on the register
DelegationPower of attorney for submissionFrom both owners

We filed 7 days before the deadline. On the day of filing, the officer asked for a newly issued land register, because the one we had was issued when the client first visited the county office and was now out of date. We printed a new one at the self-service document kiosk on the spot. The longer it has been since you first gathered your documents, the more often this happens. For applications with a deadline, check the issue-date requirement in the public notice first.

7. Through to the building demolition report

The selection results came out in mid-November. The house was selected for support, and after a site inspection the shed and toilet were included in the same demolition work. The photos and sketch submitted in advance were used as they were for the site inspection.

Demolition was finished in early December. What remained was the building demolition report (멸실신고). Article 34 of the Building Management Act requires the building’s manager to file a demolition report within 30 days of the date the building ceased to exist; this removes the house from the building register. Under the proviso of the same article, a completion report for full dismantling work counts as a demolition report, but we had to check separately whether that report had in fact been filed through the support program. This report also needed authorization from both co-owners. Because the power of attorney we first obtained from his sister already covered the demolition report after demolition, there was no need to send documents abroad again.

With clients abroad, every time documents cross the sea, it takes about 2 weeks. Including later procedures in the scope of the first power of attorney reduces the number of round trips.

His sister came home for the Lunar New Year holiday and saw the empty yard with only the persimmon tree still standing. The client said he plans to start a small vegetable garden there in spring.

8. Checklist for documents involving family abroad

If you need to submit documents to a Korean government office together with a family member living abroad, check the following first.

  1. How the public notice or guidance describes the seal certificate, the Certificate of Personal Signature, and whether originals are required
  2. Whether the family member abroad has a personal seal registered in Korea (if not, start with seal registration through a Korean mission)
  3. Count backward from the deadline, adding the mission appointment date and international mail time
  4. Whether the power of attorney covers later procedures (reports, supplements, receipt)
  5. Whether each document has an issue-date requirement

Requirements and accepted documents differ by agency and program, so each case needs to be checked individually.
