Because of this, any sale, <a href=\"https:\/\/www.thailawonline.com\/fr\/glossary\/mortgage\/\">hypoth\u00e8que<\/a>, lease or usufruct on Nor Sor 3 land is registered only after a 30-day public notice posted at the Land Office, the district office and the land itself, during which neighbours and other claimants may object and freeze the transaction.<\/p><\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"practical-points-for-a-foreign-buyer-or-lessee\">Points pratiques pour un acheteur ou un preneur \u00e9tranger<\/h2>\n\n\n<p class=\"wp-block-paragraph\"><p>Nor Sor 3 land is common in rural provinces and on the older parts of islands, and it is often priced well below chanote land nearby. It is not worthless, but it demands more work. A lease, usufruct or <a href=\"https:\/\/www.thailawonline.com\/fr\/glossary\/superficies-right\/\">superficie<\/a> can be registered on it, so a foreigner can take a real right over Nor Sor 3 land; the registration simply takes longer because of the <a href=\"https:\/\/www.thailawonline.com\/fr\/glossary\/notice-period\/\">p\u00e9riode de pr\u00e9avis<\/a>, and some Land Offices ask for a fresh boundary check first.<\/p><\/p>\n\n\n<p class=\"wp-block-paragraph\"><p><strong>Ask for the upgrade before completion, not after.<\/strong> The holder can apply to the Land Office for a ground survey and, if the adjoining owners raise no objection, the plot is converted to a chanote. A cautious buyer makes the sale conditional on that conversion, or at least on a surveyor confirming that the plot on the ground matches the certificate. Also confirm that the Nor Sor 3 has not lapsed: possession that is not used or is left in another person&#8217;s hands can be lost far faster than titled land. <a href=\"https:\/\/www.thailawonline.com\/fr\/due-diligence-in-thailand\/\">V\u00e9rifications n\u00e9cessaires<\/a> on Nor Sor 3 land should include the neighbours, not just the paper.<\/p><\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"comparing-the-three-possessory-and-ownership-documents\">Comparaison des trois documents de possession et de propri\u00e9t\u00e9<\/h2>\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Fonctionnalit\u00e9<\/th><th>Ni Sor 3<\/th><th>Ni Sor 3 Gor<\/th><th>Chanote<\/th><\/tr><\/thead><tbody><tr><td>Bien enregistr\u00e9<\/td><td>Possession<\/td><td>Possession<\/td><td>Possession<\/td><\/tr><tr><td>Survey<\/td><td>None; description only<\/td><td>Photographie a\u00e9rienne<\/td><td>GPS ground survey with posts<\/td><\/tr><tr><td>Couleur Garuda<\/td><td>Noir<\/td><td>Vert<\/td><td>Rouge<\/td><\/tr><tr><td>Public notice before registration<\/td><td>30 jours<\/td><td>Aucun<\/td><td>Aucun<\/td><\/tr><tr><td>Loss of right by another&#8217;s possession<\/td><td>1 year (Section 1375 CCC)<\/td><td>1 an<\/td><td>10 years (Section 1382 CCC)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n<p class=\"wp-block-paragraph\"><p>The last row is the one foreigners overlook.
