Please research and verify all info I provide. I am providing this for informational purposes and am not responsible for the accuracy of the info. The Usufruct needs to be Bilingual both languages. You are right it is best to register the Usufruct at the time of the Transfer of the Chanote into Her name. Why, the Usufruct needs to be submitted by Both parties, all identification needs to be verified and recorded, it saves time and "Burdens" the property from day one. Your name will be recorded on the Chanote. The Usufruct will give you all the use rights, possibly rental/lease rights, and protections. She does Not have to agree to the Usufruct, sign, or help you register it anytime After the Transfer of Property is complete. I have Zero idea Why an Estate Agent would recommend. Two people having to go back, wait in the queue, fill out and record a Usufruct, present identification, and wait for your name to be added to the Chanote. Do it the Same Time. Understand the Land Office has the "Discretion" to Refuse a Usufruct if they believe it is being used to circumvent land ownership laws in Thailand.
