Do old documents under my former name stay valid?

They usually remain valid as records of the facts at that time, for example a degree. The office may need the name change record to connect them with your current name.

Where do I get the name change record?

Usually from the district office where the change was registered. If you are unsure, ask the district office or the office that asked for the proof.

Does a German office have to accept the Thai name change?

We cannot say in general. The German office decides on the evidence and the rules for names. Ask the Standesamt or the Auslaenderbehoerde.

Should I translate only the new documents?

Not necessarily. If the office wants to see the full chain, the older documents may need translating too. Ask which documents are required.

Thai name change: linking old and new names across documents

ใบเปลี่ยนชื่อ (Bai Plian Chue)

If your name changed, German offices need proof that the old and the new name belong to the same person. In Thailand a name change is recorded at the district office and noted in the registers. Without that link, documents under different names can be treated as unrelated.

Why previous names matter

Thai documents show the name valid at the time of issue. A birth certificate may show the birth name, a degree the name at graduation, and a passport the current name. A German office comparing these documents has to be sure they describe one person. A clear name change record, or an entry on the house registration or ID card history, can provide that link.

Typical situations

People change given names or surnames in Thailand for various reasons, for example after a marriage or divorce, for personal reasons or after a change of title. The records produced and the wording differ between cases, so we cannot describe one standard form. Always work from the document you actually hold.

Name change after a marriage or a divorce.
Change of given name or surname by application at the district office.
Change of title or a correction of a spelling.

How to show the chain

Collect the document that records the change, plus documents before and after it. The translator should translate each name exactly as written and the translation should show clearly that the old and the new name are the same person, for example with a note based on the name change record. Ask the German office whether it wants all documents together or in a certain order.

Give the translator your passport so the current name is written in the form that appears there.

Legalisation and translation

Thai public documents used in Germany have so far needed legalisation by the German Embassy in Bangkok. Thailand joins the Apostille Convention on 28 February 2027, so confirm the current procedure with the embassy. German authorities generally require a complete German translation by a sworn translator. Read our guide on name transliteration for the spelling rules.

How we help, and when you need a sworn translator

DocDee reads the name change record and your other documents, summarises them in your language and lists the names found, with dates converted from the Buddhist Era. When you upload several documents, you can compare the names side by side and see where a former name appears.

We do not decide whether a name change is accepted in Germany. For official use, a sworn translator produces the official translation, which we offer as an optional paid step. The German office decides what it accepts.

Checklist

Collect the name change record from the district office.
Gather documents issued before and after the change.
Check the date of the change in B.E. and CE.
Give the translator your passport for the current spelling.
Ask the German office how it wants the chain presented.
Plan legalisation and sworn translation for each document.
