Taiwan's temples have been originated from Mainland China since Ming Dynasty. Except the 1929 Act of Temple Supervision and the 1936 Act of Temple Registration, the government has neglected the needs of Taiwan's temples for contemporary regulation. In other words, the delay of regilious legislation has obstructed the management of Taiwan's temples. There are two kinds of management organization of Taiwan's temples: administrative organization and target group. Administrative organization implies the government agencies that are related to religion. Target group means those organizations that are responsible to manage the temple itself. Taiwan's temples can be either legally-chartered or not. In the legally-chartered temples, directors of the board have to be elected by law to take charge of the temple's business management. In the nonlegally-chartered temples, the responsibility of management falls on the temple's management committee, sole manager, or supervisors. Numbers of problems arise due to incomplete and insufficient rules in the management system. The conclusion of this research is stated as follows. 1. Lack of contemporary regulation for Taiwan's temples. The existing regulation has been too out-of-date. Those vague articles make it more difficult to implement. 2. Significant problems of management of Taiwan's temples. For instance, local factions intend to involve in the management of Taiwan's temples due to the highly valuable assets owned by the temple. In addition, the property ownerships of some Temples in Taiwan still remain unsolved, because the records of property transactions and/or transfers had vanished for such a long time, e.g. hundreds of years.
