How long does legitimation of a child and parental power normally take?
Short answer
Marriage, divorce, legitimation and succession are all registered or adjudicated events with formal requirements. Where one spouse is a foreign national, the receiving country's rules matter as much as the Thai ones, so documents are usually translated and legalised before they are accepted abroad.
How this case runs end to end
Confirm marital and parental status from official records, prepare the agreement or petition, register at the district office where registration is possible, apply to the court where the matter requires a judgment, then translate and legalise the resulting record for use abroad.
Stage-by-stage timeline
| Stage | Work | Owner | Window |
|---|---|---|---|
| Document collection | Collect identity, corporate, title or court documents and prior correspondence | Client | 2–5 working days |
| Drafting | Draft or review the agreement, application, petition or filing | IVC | Depends on complexity |
| Client review | Confirm commercial terms, signatories and authority before execution | Client and IVC | 1–3 working days |
| Execution and filing | Sign, register or file with the relevant authority and retain the receipt | IVC | By the applicable deadline |
| Follow-up | Respond to official queries and archive the executed file | IVC | As required |
| Scoping | Review the facts, documents and the deadline that governs the matter | IVC | On enquiry |
What to prepare
- Passports or Thai ID cards of every party, plus company affidavits where a company is involved
- The underlying documents: draft contract, title deed, register extract or court papers
- The deadline or hearing date that governs the matter
- Evidence of authority to sign: board resolution, power of attorney or shareholder approval
- Certified translations where a document is not in Thai and will be filed with a Thai authority
- Correspondence already exchanged with the counterparty or the authority
- A single contact person who can confirm instructions and receive filings
What "How long does legitimation of a child and parental power normally take?" actually involves
This question sits within family law, matrimonial property and succession. The authority or standard that governs it directly is the Civil and Commercial Code Books 5 and 6, district registrars and the Central Juvenile and Family Court, and every case is assessed against the rules in force on the day of submission. IVC prepares the file, checks internal consistency and coordinates with the receiving office; we are not a government body and we never guarantee how an authority will decide.
A father who was not married to the mother acquires parental power through legitimation, by registration or by court order.
A will limited to Thai assets should say so, to avoid revoking a will made in another country by implication.
Divorce by mutual consent is registered at a district office only if both spouses attend and the marriage was registered in Thailand.
Rules and requirements to settle before you start
An estate administrator is appointed by court order; banks and the Land Office ask for that order rather than for a will alone.
A prenuptial agreement must be registered together with the marriage; one signed afterwards does not have the same effect.
Foreign shareholding of 50% or more brings the Foreign Business Act into play; the test is the activity performed, not the wording of the objectives clause.
BOI promotion is granted per project and per activity, and the conditions attached to it are audited afterwards rather than assumed.
The mistakes that cost the most time
The costliest pattern in legal matters is signing first and asking afterwards. A contract, a deed or a resolution creates obligations from the moment of signature, and undoing one usually costs more than the review that would have prevented it — particularly where a registration has already been made against a title or the public record.
The second is treating deadlines as administrative rather than substantive. Prescription periods, appeal windows, licence renewals and registration periods are hard cut-offs; once one passes, the strength of the underlying position becomes irrelevant and the remaining options are far narrower and far more expensive.
Why files are delayed or returned
- The prenuptial agreement was not registered with the marriage
- One spouse cannot attend the consensual divorce registration
- The estate is dealt with without a court appointment of an administrator
- Foreign documents are filed without certified translation and legalisation
- Board or shareholder approval is missing for a resolution being registered
- A capital increase is paid in without the required evidence of remittance

Practical playbook: Legal Documents and Advisory Support
Legal paperwork used in Thailand has to satisfy two tests at once: it must say what the parties intend, and it must be in the form the registrar, court or counterparty will accept — including language, signature and certification requirements.
Documents to prepare
- Passports or ID cards of every signatory
- Corporate authority documents where a company signs (affidavit, board resolution)
- The underlying documents referred to in the instrument (title deeds, contracts, judgments)
- The receiving authority's format requirements, if any
Steps and method
1. Instruction and scoping
Establish the purpose, the receiving authority and the deadline, then confirm which instrument actually achieves it.
Typical timeframe: 1–3 business days
2. Drafting
Draft in the operative language, with a Thai version where a Thai authority will read it, keeping both versions clause-for-clause aligned.
Typical timeframe: 2–7 business days
3. Execution
Sign with the required witnesses and, where needed, certification by a notarial services attorney.
Typical timeframe: 1–2 business days
4. Certification for cross-border use
Add Apostille or embassy legalisation where the document will be used outside Thailand.
Typical timeframe: 3–15 business days
Consultant tips
- Decide which language version governs and state it in the document — silence causes disputes later.
- Name the specific powers in a power of attorney; a general grant is frequently refused by registrars.
- Check the signatory's authority against the current affidavit, not an old copy.
Pitfalls to avoid
- A document drafted only in English may still need a certified Thai translation before a Thai authority accepts it.
- Undated or unwitnessed signatures are a common reason for rejection at registration.
- General information here is not legal advice on a specific dispute; a case needs its own review.

Template documents vs adviser-drafted documents
A legal document must satisfy both the parties' intent and the receiving authority's accepted form.
| Aspect | Off-the-shelf template | Drafted or reviewed by an adviser |
|---|---|---|
| Fit to the case | Covers the general situation | Adapted to the facts and to the filing authority |
| Bilingual versions | Usually silent on the governing language | States the governing language and aligns both versions |
| Execution | Risk of missing witnesses or dates | Identifies signing authority, witnesses and required certification |
| Use abroad | You research the certification chain | Apostille or embassy sequence planned from the start |
Doing it yourself vs having iVC manage the whole process
Both routes are valid. They differ in the time you spend, the risk of documents being returned, and whether an adviser reviews everything before submission.
| Aspect | Do it yourself | Managed by iVC |
|---|---|---|
| Pre-submission review | You check against the agency's published requirements | An adviser checks each document against the destination's rules first |
| Your time | You travel, queue and follow up yourself | We file and follow up; you receive progress updates |
| Rejection risk | Common causes: name spelling mismatch, expired documents, wrong certification order | We check the usual rejection triggers at source and fix them first |
| Specialist knowledge | You research each agency's rules yourself | A team with 15+ years of casework advises throughout |
| If something goes wrong | You restart the steps yourself | We assess the options and plan the fix immediately |
We work as advisers, not just a document courier
More than 15 years of casework (since 2011) in translation, certification and visa document preparation shows us the patterns behind repeated rejections, so we plan around them from the start.
- Case assessment first
- We review the profile, destination country and receiving authority before recommending a certification route.
- A document plan per person
- We sequence what must be re-issued, translated first, and certified in which order.
- Risks flagged early
- We point out the usual rejection triggers, such as name spelling that differs from the passport or document age limits.
- Follow-through to the end
- Regular progress updates, and immediate options if the authority requests more documents.
- Advice after completion
- The same set is often reused in the next step; we check whether it still qualifies or needs re-issuing.
If you would rather not chase each step yourself, send the case details for an assessment first, then decide.
