The agreement must be in writing, signed by both future spouses and at least two witnesses, and registered with the marriage at the district office (amphur), where it is noted on the marriage register (Kor Ror 2). An agreement signed weeks earlier but not presented at the marriage registration is void. A Thai text is filed; couples usually prepare a bilingual version in advance rather than rely on a translation done at the counter.<\/p><\/p>\n\n\n<p class=\"wp-block-paragraph\"><p><strong>\u0e21\u0e32\u0e15\u0e23\u0e32 1465<\/strong> limits the content.

Couples with assets abroad often need a second, coordinated instrument under the law of the home country, because Thai registration does not by itself guarantee enforcement in England, Australia or the United States; see the guide on <a href=\"https:\/\/www.thailawonline.com\/th\/will-a-thai-prenuptial-agreement-hold-up\/\">whether a Thai prenuptial agreement holds up abroad<\/a>.<\/p><\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"what-the-agreement-changes-at-divorce\">What the agreement changes at divorce<\/h2>\n\n\n<p class=\"wp-block-paragraph\"><p>Without an agreement, property acquired during the marriage is sin somros and is split equally under Section 1533 at divorce, while assets owned before the marriage, and inheritances and <a href=\"https:\/\/www.thailawonline.com\/th\/glossary\/gift\/\">\u0e02\u0e2d\u0e07\u0e02\u0e27\u0e31\u0e0d<\/a> received during it, remain sin suan tua under Section 1471.

Any two people registering a marriage in Thailand, whether both foreign or one Thai and one foreign, can register a prenuptial agreement with the marriage. The text filed at the amphur must be in Thai, so foreigners normally sign a bilingual version and bring a translator or an interpreter on the day.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-2\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">Is a prenuptial agreement valid in Thailand if it was not registered with the marriage?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>No. Section 1466 of the Civil and Commercial Code makes an unregistered prenuptial agreement void. An agreement signed after the wedding is treated as an agreement between spouses under Section 1469 and can be cancelled by either spouse at any time during the marriage or within one year after it ends.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-3\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">Can a Thai prenuptial agreement choose a foreign law?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>No. Section 1465 provides that a clause making the spouses&#8217; property relations subject to the law of another country is void. The rest of the agreement survives, but a couple with assets abroad usually needs a separate agreement drafted under the law of the country where those assets sit.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n<p class=\"wp-block-paragraph\"><p>\u0e14\u0e39\u0e40\u0e1e\u0e34\u0e48\u0e21\u0e40\u0e15\u0e34\u0e21: <a href=\"https:\/\/www.thailawonline.com\/th\/glossary\/marital-property\/\">\u0e0b\u0e34\u0e19 \u0e0b\u0e2d\u0e21\u0e23\u0e2d\u0e2a<\/a>, <a href=\"https:\/\/www.thailawonline.com\/th\/glossary\/personal-property\/\">\u0e1a\u0e32\u0e1b\u0e2a\u0e27\u0e19\u0e15\u0e31\u0e27<\/a>, <a href=\"https:\/\/www.thailawonline.com\/th\/glossary\/postnuptial-agreement\/\">\u0e02\u0e49\u0e2d\u0e15\u0e01\u0e25\u0e07\u0e2b\u0e25\u0e31\u0e07\u0e2a\u0e21\u0e23\u0e2a<\/a>, <a href=\"https:\/\/www.thailawonline.com\/th\/glossary\/marriage-certificate\/\">marriage certificate (Kor Ror 3)<\/a>, \u0e41\u0e25\u0e30\u0e04\u0e39\u0e48\u0e21\u0e37\u0e2d\u0e09\u0e1a\u0e31\u0e1a\u0e40\u0e15\u0e47\u0e21\u0e2a\u0e33\u0e2b\u0e23\u0e31\u0e1a <a href=\"https:\/\/www.thailawonline.com\/th\/prenuptial-agreement-thailand\/\">\u0e02\u0e49\u0e2d\u0e15\u0e01\u0e25\u0e07\u0e01\u0e48\u0e2d\u0e19\u0e2a\u0e21\u0e23\u0e2a\u0e43\u0e19\u0e1b\u0e23\u0e30\u0e40\u0e17\u0e28\u0e44\u0e17\u0e22<\/a> \u0e41\u0e25\u0e30 <a href=\"https:\/\/www.thailawonline.com\/th\/not-to-include-in-a-thai-prenuptial-agreement\/\">what not to include in a Thai prenuptial agreement<\/a>.<\/p><\/p>","protected":false},"excerpt":{"rendered":"<p>A prenuptial agreement (\u0e2a\u0e31\u0e0d\u0e0d\u0e32\u0e01\u0e48\u0e2d\u0e19\u0e2a\u0e21\u0e23\u0e2a, sanya kon somrot, also written ante-nuptial agreement or simply prenup) is a contract between two people [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":214,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"pmpro_default_level":"","site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":"","rank_math_focus_keyword":"prenuptial agreement thailand","rank_math_title":"Prenuptial Agreement Thailand: Section 1466 | ThaiLawOnline","rank_math_description":"Prenuptial agreement in Thailand: a contract on marital property registered with the marriage at the amphur.
