A DTV family plan needs a separate application and record set for each person. The principal holder’s visa establishes an important part of the relationship between the files, but it does not replace a spouse’s passport, a child’s relationship evidence or the documents required for that person’s application.
The DTV family category covers a spouse and children under 20 of a DTV holder. Read the responsible mission’s instructions for the exact evidence and application sequence. A family travelling together may still have different nationalities, residence documents, passport expiry dates and application requirements.
Start by listing every traveller and the immigration route proposed for that person. Then build the links between the files. This is easier than collecting a large folder labelled “family documents” and discovering during submission that nobody knows which certificate belongs in which application.
Identify the principal applicant and the relationship
The principal applicant qualifies through their own DTV basis, such as workcation or an accepted activity. The family application then needs to establish the qualifying relationship and link to the relevant DTV holder.
Use the legal relationship described by the category. Do not assume an unmarried partner, parent, sibling or adult child is included simply because the household considers them family. If the person is outside the published category, discuss a separate route that fits their circumstances.
For a child, check the age condition against the application and travel plan. A child approaching 20 needs a careful review of the relevant authority’s instructions. Do not assume a birthday has no effect because the family began planning while the child was younger.
For adopted children, name changes or complex parental arrangements, identify the documents that establish the actual relationship. A short explanation can connect the records, but it cannot replace a required legal certificate.
Ask how the applications should be sequenced
Some family plans depend on the principal DTV being issued before the dependant submits the evidence linking to it. Do not assume all applications can be completed simultaneously without checking the mission’s procedure.
For example, London’s DTV checklist includes the DTV holder’s visa and relationship evidence in its family category. That instruction matters when planning the order of the files. It does not establish a universal sequence for every other mission.
Ask whether the family applications can be linked in the system and how the principal reference should be supplied. Keep a record of the response if the published instructions do not settle the question.
Leave time between the principal decision and any dependant submission that relies on it. Buying one non-refundable family itinerary before the sequence is understood can create pressure to travel before every person has the correct documents.
Build a family control sheet
Keep a private table with one row per applicant. It should help you organise the work without becoming an informal substitute for the application forms.
| Field | Why it is useful |
|---|---|
| Passport name and nationality | Prevents copying another family member’s identity details |
| Passport expiry | Identifies an early renewal issue |
| Proposed visa basis | Separates principal and dependant applications |
| Residence or application location | Helps establish the correct mission for each applicant |
| Relationship document | Shows which certificate supports the link |
| Application reference and status | Prevents confusing payment, submission and approval |
| Visa and stay dates after travel | Supports individual deadline tracking |
Do not place complete passport numbers or sensitive certificates in a spreadsheet shared more widely than necessary. Give access only to people who need it for the task.
Use separate folders for each applicant, with a common folder for shared relationship records. When uploading, check the actual file contents; similar filenames make it easy to attach one child’s passport to another child’s application.
Review marriage and birth records early
Check the names, dates and issuing authorities on relationship documents. Compare them with the passports being used now. Differences can be legitimate, but they need a documentary explanation.
A marriage certificate may show a previous surname. A birth certificate may use a parent’s earlier passport name. Keep the relevant name-change record or other linking evidence where required. Do not edit the certificate or translate the name differently simply to make the files look consistent.
Use the full certificate where the mission requests one. A short extract may omit parents’ names or other details relevant to establishing the relationship. Ask the issuing authority for the appropriate version early enough to avoid delaying the whole family.
Foreign certificates can require translation, certification or legalisation. Follow the responsible mission’s instructions about the document’s country of issue and accepted authorities. Our foreign marriage certificate guide explains the questions to settle before paying for a translation.
Check minors’ additional documents
A child’s application can involve records beyond a birth certificate. The applicable checklist may request parental identity, residence evidence or other supporting documents. Check those requirements for the child’s age and circumstances.

ors under 16. Applicants using London should read that section together with the family-category list. Applicants elsewhere should use their own mission’s requirements rather than transferring London’s list into a supposed worldwide rule.
If one parent is travelling separately, or the child has a guardianship or custody arrangement, resolve the documentation before booking. Visa eligibility, airline rules and permission for a minor to travel are related practical questions but are not identical procedures.
Keep originals available where the authority requires them. A photograph of a certificate in a messaging app may be useful for an early discussion, but it should not be assumed to satisfy the application standard.
Plan finances for each applicant
Do not assume one set of funds automatically covers unlimited dependants. Read the family-category financial instruction and ask about ownership, sponsorship or shared accounts where the published guidance leaves a genuine question.
Make a budget for each application fee as well as the financial evidence. Add translation, legalisation, document-issue and travel costs separately. A family can underestimate preparation costs when it multiplies only the principal visa fee.
If a parent’s statement is proposed for a child, establish the accepted method of linking the funds to the application. A relationship certificate explains who the parent is; it does not automatically answer every financial-evidence question.
Our DTV financial evidence guide explains how to distinguish account ownership, statement dates and application charges. Keep the family’s genuine financial position clear rather than repeatedly transferring the same funds to create a misleading appearance across several accounts.
What London’s family checklist actually asks for
London’s September 2026 family list includes the passport biodata page, a recent photograph, proof of permanent residence in its stated territory, financial evidence of at least £12,000 (500,000 baht), a police-clearance certificate issued within six months, the principal holder’s DTV and relationship evidence. Its examples of relationship documents include marriage, birth and adoption certificates.
For minors under 16, the additional list includes a full birth certificate showing parents’ names, parental passport or ID, parental council-tax or utility bills and a recent official parental UK or Ireland bank statement showing name and address. Read the complete page for the translation and additional non-UK-citizen instructions. These specific London requirements are useful for building a London family file; they are not a substitute for another mission’s list.
Coordinate the principal evidence without duplicating mistakes
The family files should refer to the same principal holder consistently. Check the principal’s passport name, visa category, visa record and relevant reference against every dependant application.
If the principal renews a passport or receives a corrected visa document, identify which family files need updating. Do not leave one dependant linked to an outdated record while another uses the new one.
A change in the principal’s plans can affect the family plan. If the principal no longer intends to travel, their qualifying activity changes or the visa is not issued, ask the mission what happens to the proposed dependant applications. Do not assume the original timetable survives unchanged.
Avoid uploading the principal’s entire professional history to every family member’s file unless requested. Supply the records the family checklist needs, with a clear link. Extra documents can expose unnecessary personal information and make the relevant evidence harder to find.
Test a mixed-nationality household plan
Consider a hypothetical married couple with a child. The principal works remotely, the spouse holds a different passport and the child has a recently renewed passport. All three live together, but their documents do not look identical.
The principal prepares workcation evidence. The spouse establishes the marriage relationship and supplies their own identity and residence records. The child’s file establishes parentage and uses the new passport consistently. The family checks which mission can accept each application before assuming that one household address settles every jurisdiction question.
This example shows why separate files help. It also prevents a mistake in which the principal’s eligibility is described as approval for the entire household. Each application still needs its own decision.
Maintain individual records after arrival
When the family enters Thailand, inspect each admission record. Keep the visa-validity dates separate from each person’s current permitted-stay deadline. Family members who enter on different dates should not rely on a single shared reminder.
If only one person later travels abroad, update that person’s records on return. If the family seeks extensions, obtain the local instructions for the principal and dependants and establish whether attendance or linked filing is required.
Our DTV validity and stay guide explains why a five-year visa and a current stay have different dates. School calendars, rental contracts and family flights should fit around the permission actually held.
Visa Support Thailand offers DTV consultation. Read the DTV overview or contact us with the number of applicants, ages, nationalities, residence locations and proposed principal category. You can describe those facts first without sending children’s full identity documents in an initial message.
