Chindanai ***********************
For reference, I found the Unofficial translation from the Royal Thai Police website:
**************************************************************
Section 76. Any alien who fails to comply with the provisions of Section 37
(2), (3), (4) or (5), shall be punished by a fine not exceeding five thousand baht and a daily fine of not exceeding two hundred baht until full compliance.
---
Section 37. An alien who is permitted to stay in the Kingdom temporarily
shall do the following —
5) Staying in the Kingdom longer than ninety days, an alien shall notify the
competent official at the Immigration Division, of his or her residence, in writing, without
delay, upon the completion of a ninety day period. This shall be repeated at every ninety
day interval. If there is an immigration office in the locality, the notification may be made to
the competent official of that immigration office.
Good luck.
