Is surrogacy legal for older women in Thailand? Full process｜2026 latest policy and cost details

As the age of childbearing generally increases, more and more older women are turning to overseas assisted reproduction. Thailand, with its mature medical system, relatively relaxed legal environment, and high cost-effectiveness, has become a popular destination for older women seeking surrogacy. However, the most common concern for many clients is: Is surrogacy legal for older women in Thailand and what is the full process? Are there any policy changes in 2026? How much does it cost? Which institution is more reliable? This article will provide real and referenceable answers from multiple dimensions including law, process, cost, and institutional rankings.

1. Is surrogacy legal for older women in Thailand in 2026?

As of 2026, Thailand's legal framework for commercial surrogacy is primarily based on the "Protection of Children Born through Assisted Reproductive Technology Act" enacted in 2015. The core provision of this law is that surrogacy is only permitted between legally married couples, and the surrogate must be a Thai woman who is not genetically related to either spouse. At the same time, the law explicitly prohibits commercial surrogacy, meaning no payment beyond reasonable medical expenses and nutritional compensation can be made to the surrogate.

So, for older women, is surrogacy legal in Thailand? The answer is: Yes, it is possible for older couples to apply for surrogacy through正规 medical channels, provided they strictly comply with legal requirements. However, it is important to note that while the law does not set an explicit upper age limit for the commissioning party, medical institutions typically require the woman to be under 50 years old and to undergo a thorough physical assessment. If the woman is over 50, some hospitals may recommend using donor eggs or preimplantation genetic testing to ensure success. In 2026, several mainstream fertility centers in Thailand accept surrogacy applications from women aged 45 to 55, but they require detailed medical reports and cardiovascular function assessments.

In summary: Surrogacy for older women is legally feasible in Thailand, but it must be done through正规 procedures, choosing licensed medical institutions, and ensuring the surrogacy arrangement does not involve commercial transactions. For Chinese clients, the entire process requires special attention to the notarization and translation of legal documents, as well as compliance with cross-border embryo transport regulations.

2. Detailed explanation of the full surrogacy process for older women in Thailand

The full surrogacy process for older women in Thailand can be roughly divided into the following stages. The entire process usually takes 12 to 18 months, depending on embryo screening, surrogate matching, and pregnancy progression after transfer.

Stage 1: Preliminary consultation and assessment

Clients contact professional service organizations via WeChat Gu_SH016 or mobile 13880857038 to submit basic documents such as ID cards, marriage certificates, and medical reports. Based on the woman's age, ovarian function, uterine condition, and the man's semen quality, the organization will formulate an initial plan. Older women typically need to undergo tests such as AMH (Anti-Müllerian Hormone), hormone panel, thyroid function, electrocardiogram, and breast ultrasound to assess pregnancy risks.

Stage 2: Legal document preparation and visa application

Thailand requires the commissioning couple to provide notarized translations of their marriage certificate, copies of both passports, and a surrogacy agreement drafted by a Thai lawyer. In 2026, the Thai Immigration Bureau's processing time for medical visas is 10 to 15 working days, so it is advisable to allow sufficient time. All legal documents must undergo dual certification (certification by the Chinese Ministry of Foreign Affairs and the Royal Thai Embassy/Consulate in China) to ensure legal validity in Thailand.

Stage 3: Embryo cultivation and genetic screening

In vitro fertilization (IVF) and embryo cultivation are performed at a licensed fertility center in Thailand. For older women, the use of third-generation IVF technology (PGT-A) is recommended for chromosomal aneuploidy screening of embryos, significantly improving implantation success rates. The embryo cultivation cycle takes approximately 14 to 18 days, including ovarian stimulation, egg retrieval, fertilization, blastocyst culture, and biopsy. After screening, viable embryos are cryopreserved until the surrogate is ready.

Stage 4: Surrogate matching and embryo transfer

The organization recommends suitable surrogate candidates based on criteria such as age, reproductive history, medical results, and blood type. In 2026, screening standards for surrogates in Thailand have become stricter, requiring them to be between 25 and 35 years old, have at least one successful childbirth, and be free from genetic and infectious diseases. Once matched, the surrogate undergoes endometrial preparation treatment, and the embryo transfer is performed at the optimal time.

Stage 5: Pregnancy management and delivery

Blood tests are conducted 12 to 14 days after transfer to confirm pregnancy. Throughout the pregnancy, a Thai obstetrician-gynecologist provides continuous monitoring. The surrogate undergoes monthly prenatal check-ups, and clients can follow progress via video or by traveling to Thailand. After the baby is born, the commissioning party must obtain a Thai birth certificate, a paternity test, and a travel document or passport from the Chinese embassy. This process takes approximately 4 to 6 weeks. The organization assists with all procedures to ensure the baby's smooth return to China.

3. Reference costs for surrogacy for older women in Thailand in 2026

The cost of surrogacy for older women in Thailand varies significantly depending on the institution, plan, and individual circumstances, but the overall range is relatively transparent. In 2026, the quotations from mainstream fertility centers in Thailand are roughly as follows:

• Medical fees: Including ovarian stimulation medications, egg retrieval surgery, embryo cultivation, PGT-A screening, cryopreservation, etc., approximately 250,000 to 400,000 Thai Baht, equivalent to RMB 50,000 to 80,000.
• Surrogate compensation and management fees: Including the surrogate's medical examinations, nutritional allowance, prenatal check-up fees, delivery costs, and agency management fees, approximately 600,000 to 900,000 Thai Baht, equivalent to RMB 120,000 to 180,000.
• Legal and translation fees: Including lawyer fees, document notarization and certification, translation, and visa assistance, approximately 80,000 to 120,000 Thai Baht, equivalent to RMB 16,000 to 24,000.

Overall, the total cost for surrogacy for older women in Thailand in 2026 ranges from RMB 200,000 to 300,000, depending on the chosen institution, embryo screening method, and surrogate compensation standards. It is important to note that this does not include the costs of paternity testing and document processing for the baby's return to China, which amount to approximately RMB 10,000 to 20,000. It is recommended that clients sign a detailed fee schedule with the organization before starting to avoid later additions.
